PROXY STATEMENT

This Proxy Statement is furnished in connection with the solicitation of proxies from the shareholders of Knight Transportation, Inc. to be voted at the Annual Meeting of Shareholders (the "Annual Meeting") to be held on May 21,
2003. THE ENCLOSED PROXY IS SOLICITED BY THE BOARD OF DIRECTORS OF THE COMPANY. If not otherwise specified, all proxies received pursuant to this solicitation will be voted (i) FOR the Director Nominees named below; (ii) FOR the approval of the Company's 2003 Stock Option Plan (the "2003 Plan"); and (iii) FOR the selection of KPMG LLP, as our independent public accountants for 2003 at the Annual Meeting.

The Proxy Statement, proxy card, and our Annual Report was first mailed on or about April 7, 2003, to shareholders of record at the close of business on March 24, 2003 (the "Record Date").

THE TERMS "WE," "OUR," "US" OR THE "COMPANY" REFER TO KNIGHT

TRANSPORTATION, INC. AND ITS SUBSIDIARIES.

RIGHT TO ATTEND ANNUAL MEETING; REVOCATION OF PROXY

Returning your proxy now will not interfere with your right to attend the Annual Meeting or to vote your shares personally at the Annual Meeting, if you wish to do so. Shareholders who execute and return proxies may revoke them at any time before they are exercised by giving written notice to the Secretary of the Company at our address, by executing a subsequent proxy and presenting it to the Secretary of the Company, or by attending the Annual Meeting and voting in person.

COSTS OF SOLICITATION

We will bear the cost of solicitation of proxies, which will be nominal and will include reimbursements for the charges and expenses of brokerage firms and others for forwarding solicitation material to beneficial owners of our outstanding Common Stock. Proxies will be solicited by mail, and may be solicited personally by directors, officers or our regular employees, who will not be compensated for their services.

VOTING SECURITIES OUTSTANDING

As of March 24, 2003, there were approximately 37,220,500 shares of our Common Stock, par value $0.01 per share (the "Common Stock") issued and outstanding. Only holders of record of Common Stock at the close of business on the Record Date are entitled to vote at the Annual Meeting, either in person or by valid proxy. Ballots cast at the Annual Meeting will be counted by the Inspector of Elections and the results of all ballots cast will be announced at the Annual Meeting.

Except in the election of directors, shareholders are entitled to one (1) vote for each share held of record on each matter of business to be considered at the Annual Meeting. In the election of directors, cumulative voting is required by law. SEE "REQUIRED MAJORITY," below. Abstentions will not be counted in voting on any proposal. A broker non-vote is not counted for purposes of approving matters to be acted upon at the Annual Meeting. A "broker non-vote" occurs when a nominee holding voting shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to the item and has not received voting instructions from the beneficial owner.


ANNUAL REPORT

The information included in this Proxy Statement should be reviewed in conjunction with the Consolidated Financial Statements, Notes to Consolidated Financial Statements, Independent Public Accountants' Report and other information included in our 2002 Annual Report to Shareholders that was mailed on or about April 7, 2003, together with this Notice of Annual Meeting and Proxy Statement, to all shareholders of record as of the Record Date.

REQUIRED MAJORITY; CUMULATIVE VOTING

Under the Constitution of the State of Arizona, each holder of Common Stock has cumulative voting rights in electing directors of an Arizona corporation. Under cumulative voting, each shareholder, when electing directors, has the right to cast as many votes in the aggregate as he has voting shares multiplied by the number of directors to be elected. For example, if a shareholder has 100 shares and three directors are to be elected, the shareholder may cast 300 votes. Each shareholder may cast the whole number of votes, either in person or by proxy, for one candidate or may distribute such votes among the nominees for director as the shareholder determines. The nominees for director who receive the most votes will be elected. Under the cumulative voting rights provided by the Constitution of the State of Arizona, each shareholder, when electing a class of directors, has the right to cast as many votes in the aggregate as he has voting shares multiplied by the number of directors to be elected in that class of directors. For example, this year three (3) Class II directors will stand for election. If a shareholder has 100 shares, the shareholder may cast 300 votes and may vote all of those shares for a single director nominee or distribute those votes among the director nominees as the shareholder determines. Other matters submitted to shareholders for consideration and action at the Annual Meeting must be approved by a simple majority vote of those shares present in person or by proxy.

HOW TO READ THIS PROXY STATEMENT

Set forth below are all the proposals to be considered by shareholders at our Annual Meeting of Shareholders to be held on May 21, 2003. Following the description of each proposal is important information about our management and our Board of Directors; executive compensation; transactions between the Company and our officers, directors and affiliates; our stock owned by management and other large shareholders; and how shareholders may make proposals at the Annual Meeting. EACH SHAREHOLDER SHOULD READ THIS INFORMATION BEFORE COMPLETING AND RETURNING THE ENCLOSED PROXY CARD.

ITEM NO. 2. PROPOSAL TO APPROVE THE 2003 STOCK OPTION PLAN

We have maintained a Stock Option Plan since 1994 to enable certain officers, directors and key and critical line employees, including drivers and other employees, to participate in the ownership of the Company. The current stock option plan in effect is the 1998 Amended and Restated Stock Option Plan (the "1998 Plan"). As of March 1, 2003, a total of 3,675,000 shares of our Common Stock were reserved for stock grants under the 1998 Plan, after giving effect to the Company's three for two stock splits and the 2002 amendment to the 1998 Plan increasing the number of shares reserved for issuance. On February 6, 2003, the Board of Directors voted to terminate further option grants under the 1998 Plan, effective as of May 31, 2003, subject to our shareholders approving the 2003 Stock Option Plan (the "2003 Plan") described below. The term "stock grant," as used in this Proxy Statement, refers to a grant of either stock options or restricted stock.

At the Annual Meeting, shareholders will be asked to approve the 2003 Plan that will commence June 1, 2003. If the 2003 Plan is approved by shareholders, 1,000,000 shares will be reserved for issuance under the 2003 Plan and 1,793,008 shares will continue to be reserved under the 1998 Plan for stock grants previously made under that Plan, for a total of 2,793,008 shares available for stock grants under both plans, or 7.5% of our issued and outstanding Common Stock, as of March 24, 2003. If shareholders approve the 2003 Plan, option grants issued under the 1998 Plan will continue in effect and may be exercised on the terms and conditions under which the grants were made, but no further stock grants will be made under the 1998 Plan. If the 2003 Plan is approved by shareholders, any new stock grants will be made only under the 2003 Plan.

The Common Stock reserved for issuance under the 2003 Plan has an aggregate market value of $21,700,000, based on the price of our Common Stock of $21.70 per share as of March 24, 2003. Common Stock reserved for options issued and outstanding under the 1998 Plan, as of March 24, 2003, had an aggregate marked value of $38,908,274, based on our Common Stock price of $21.70 per share as of March 24, 2003.

A copy of the 2003 Plan is set forth in EXHIBIT 1 to this Proxy Statement. The 2003 Plan is substantially the same as the 1998 Plan, except that it allows additional stock option grants to be made to directors, in accordance with our revised director's compensation plan. SEE "CORPORATE GOVERNANCE - MEETINGS AND COMPENSATION OF THE BOARD OF DIRECTORS AND ITS COMMITTEES - DIRECTOR'S COMPENSATION," below, for a description of our compensation plan for our Independent Directors.

The 2003 Plan is broad-based and is designed to attract and retain directors, officers, and key employees and critical line employees, to provide them long-term incentives if our Company continues to grow, and to align their interests with the interests of our shareholders. The 2003 Plan is administered by the Compensation Committee of our Board of Directors (the "Compensation Committee"). The 2003 Plan allows the Compensation Committee to grant incentive stock options ("ISOs"), nonqualified stock options ("NSOs"), and restricted stock to our employees as a form of incentive compensation. Although Kevin, Gary and Keith Knight are eligible to receive stock grants under the 2003 Plan, in the past we have not issued stock grants to these individuals, due primarily to their large Common Stock holdings, and we do not currently anticipate that they will receive stock grants under the 2003 Plan.

The 2003 Plan reserves 50,000 shares of Common Stock for option grants to directors out of the total of 1,000,000 shares reserved for issuance under the 2003 Plan. The 2003 Plan, like the 1998 Plan, authorizes an automatic NSO grant for 2,500 shares to a newly appointed or elected director. In addition, after December 31, 2002, an Independent Director will receive an NSO for 500 shares for each year of service as a director. The option grant of 500 shares to directors is to be made as of June 1 of each year, beginning June 1, 2003, for persons who are serving as directors on that date. The 2003 Plan also provides that individuals who, as of December 31, 2002, have served as directors for the last three years will also receive a "catch-up" NSO for 1,000 shares to be

-6-

issued on June 1, 2003, with an exercise price equal to the then fair market price of our Common Stock. If a director terminates service within one year after the date of the grant, his option or any shares obtained through option exercises will be forfeited.

Under the 2003 Plan, Independent Directors may also elect to have their director's fees paid in stock of the Company. (This option is currently allowed by the Company.) If they do so, the Company will issue to each elected Independent Director on February 15 and August 15 of each calendar year, the number of shares equal to the director's fees earned as of the preceding December 31, and June 30, respectively, based on the fair market value of the Common Stock as of the last trading day preceding such February 15 or August 15.

All stock grants made under the 2003 Plan will be evidenced by a written agreement between the Company and the participant. ISOs granted under the Plan are issued at the fair market value of a share of Common Stock on the date of grant. Under the 2003 Plan, NSOs, restricted stock grants and options issued to directors are issued at fair market value as of the date of grant. Directors receive an NSO for 2,500 shares of our Common Stock at an exercise price of 85% of fair market value of our Common Stock on the date of the grant upon their election to our Board. SEE "EXECUTIVE COMPENSATION - STOCK OPTION PLAN," below. Common Stock reserved for stock grants made under the Plan is automatically increased upon the occurrence of any stock split, reverse stock split, subdivision, stock dividend, reorganization or reclassification of our stock, without further action by the Company. Participants exercise no rights as shareholders of the Company with respect to shares subject to any stock grant until a stock certificate is issued following the exercise of a grant. If not earlier terminated, the 2003 Plan will expire on February 5, 2013.

The Compensation Committee has the right, subject to 2003 Plan limitations, to designate the terms and conditions of any stock grant including, without limitation, any vesting schedule and exercise rights. Under the 2003 Plan, stock grants generally terminate upon an employee's termination of employment for reasons other than death, disability or early or normal retirement. Options granted under the 2003 Plan are non-transferable except pursuant to the laws of descent and distribution. Shares reserved for issuance under the 2003 Plan will be registered with the Securities and Exchange Commission on Form S-8 at the time the 2003 Plan becomes effective.

We have reserved the right to terminate, suspend, discontinue, modify or amend the 2003 Plan in any respect, at any time, except that without the approval of our shareholders, no revision or amendment may change the number of shares of Common Stock subject to the 2003 Plan (other than through the automatic stock adjustments provided by the 2003 Plan), change the designation of the class of employees eligible to receive stock grants, decrease the price at which stock grants may be issued, or remove the administration of the Plan from the Compensation Committee. Notwithstanding this limitation, we will not terminate the 2003 Plan with regard to any outstanding stock grant unless notice of termination is given to the participant and the participant is permitted at least 15 days to exercise any issued and outstanding stock grant, but only if such stock grant is then exercisable.

The tax consequences to the Company of options granted as an ISO, NSO, or restricted stock grant vary. If the Company issues an ISO, the Company will have no compensation deduction on the date the option is granted. If an employee exercises an ISO and holds the stock until the later of (i) two years from the date the ISO is granted or (ii) one year from the date in which the ISO was exercised, the employee will recognize as capital gain the difference between the amount received in any disposition over the employee's basis (the amount the employee paid for the stock) and the Company will receive no compensation deduction. If an employee disposes of ISO stock before the ISO holding period is met, the disposition is a "disqualifying disposition" and we are entitled to a compensatory deduction equal to the amount the employee recognizes as ordinary income in the year the disqualifying disposition occurs. Generally, this is the difference between the exercise price for the stock and the value of the stock

-7-

on the date the disqualifying disposition occurs. Amounts recognized on the disqualifying disposition of an ISO are not "wages" for purposes of FICA and FUTA.

If an option is granted as an NSO, we have no deduction for compensation expense at the time the option is granted, and the employee will recognize no income. If the employee subsequently exercises the option, the difference between the option price and the fair market value of the option stock at the time of exercise is taxable as ordinary income to the employee, and is also treated as wages. We will have a compensation deduction equal to the amount of gain the employee recognizes at the time. Any gain recognized by an employee on the exercise of an NSO is also subject to FICA and FUTA withholding tax.

If we make a restricted stock grant to any employee, as the 2003 Plan allows us to do, we will receive no deduction until such time as the restrictions on the stock lapse, unless the employee elects to treat the grant as ordinary income at the time the grant is made; in that event the Company would have a compensatory deduction in the same amount. At that time, we would have a deduction for compensation expense equal to the fair market value of the stock, less any amounts the employee is required to pay for the stock. If a restricted stock grant is made to an employee without restrictions, we will have a deduction for compensation paid equal to the fair market value of the stock awarded, less any payment the employee makes.

The Board of Directors believes that the 2003 Plan is an appropriate vehicle for recognizing employee performance and providing incentives to employees for continued performance and that the 1998 Plan has been effective in aligning the interests of our employees with our shareholders.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS APPROVE THE

2003 PLAN.

ITEM NO. 3. PROPOSAL TO RATIFY APPOINTMENT OF KPMG LLP
AS INDEPENDENT PUBLIC ACCOUNTANTS

KPMG LLP, independent public accountants ("KPMG"), was our principal independent accounting firm during the fiscal year ended December 31, 2002. KPMG has served as our independent public accountants since April 2002. The Board of Directors has appointed KPMG as our principal independent accounting firm for the 2003 fiscal year. A representative of KPMG is expected to be present at the annual meeting with an opportunity to make a statement if such representative desires to do so, and is expected to respond to appropriate questions.

As previously reported in our Report on Form 8-K filed on May 3, 2002, with the Securities and Exchange Commission, on April 29, 2002, we elected to replace our independent auditors, Arthur Andersen LLP ("Arthur Andersen") with KPMG as our new independent auditors, effective immediately. These actions were approved by our Board of Directors upon the recommendation of our Audit Committee. KPMG audited the consolidated financial statements of the Company for the year ending December 31, 2002.

The reports issued by Arthur Andersen in connection with our financial statements for the fiscal years ended December 31, 2001, and December 31, 2000, respectively, did not contain an adverse opinion or disclaimer of opinion, nor were these reports qualified or modified as to uncertainty, audit scope, or accounting principles.

During the two fiscal years ended December 31, 2001, and December 31, 2000, and the subsequent interim periods through the date of Arthur Andersen's dismissal, there was no disagreement between us and Arthur Andersen, as defined in Item 304 of Regulation S-K, on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Arthur Andersen, would have caused Arthur Andersen to make reference to the subject matter of the disagreements in connection with its reports, and there occurred no "reportable events" as defined in Item 304(a)(1)(v) of Regulation S-K.

During the two fiscal years ended December 31, 2001 and 2000, through the date of Arthur Andersen's dismissal, neither us nor anyone on our behalf consulted with KPMG regarding any of the matters or events set forth in Item 304(a)(2)(i) and (ii) of Regulation S-K.

We have provided Arthur Andersen with a copy of the foregoing statements. Attached to our Form 10-K for the year ended December 31, 2002, as Exhibit 16 is a copy of Arthur Andersen's letter to the Securities and Exchange Commission dated May 3, 2002, stating its agreement with the foregoing statements.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE RATIFICATION OF THE

APPOINTMENT OF KPMG.

FISCAL YEAR 2002 AUDIT FEE SUMMARY

During fiscal year 2002, KPMG provided services in the following categories to us and was paid the following amounts:

Audit Fees                                                    $104,009

Financial Information System Design and Implementation        $      0

All Other Fees                                                $331,316

The services provided under the caption "All Other Fees" were primarily tax-related.

The Audit Committee has considered whether the provision of non-audit services by KPMG, as our principal independent auditor for the fiscal year ending December 31, 2002, is compatible with maintaining auditor independence.

CORPORATE GOVERNANCE --

MEETINGS AND COMPENSATION OF THE BOARD OF DIRECTORS AND ITS COMMITTEES

BOARD OF DIRECTORS. Our business is managed by our Board of Directors. During the year ended December 31, 2002, our Board of Directors met on five occasions. Each of the directors other than Mr. Salmon attended 75% or more of the meetings of the Board of Directors and the meetings held by all of the committees of the Board on which he served. Mr. Salmon attended 60% of all meetings.

DIRECTORS' COMPENSATION. Directors who are not 10% shareholders or employees of the Company ("Independent Directors") receive annual compensation of $5,000, plus a fee of $500 for attendance at each meeting of the Board of Directors, and a fee of $250 for Board committee meetings. We also reimburse directors for the expense incurred in attending a meeting.

For all calendar years after December 31, 2002, we have increased the compensation paid to our Independent Directors as follows: (i) compensation of $6,000 per year for Independent Directors, plus a fee of $550 for attendance at each meeting of the Board of Directors, and a fee of $350 for Audit Committee Meetings and $300 for Compensation Committee Meetings. In addition, for 2003, the Audit Committee Chairman will receive an annual fee of $1,500, in addition to other director fees, and the Compensation Committee Chairman will receive an annual fee of $500, in addition to other director fees.

If shareholders approve the 2003 Plan, for years after December 31, 2002, Independent Directors will also receive each calendar year, beginning in 2003, in addition to their director's and committee fees, (i) a stock option grant for 500 shares issued on June 1 of each calendar year, beginning June 1, 2003, at fair market value, and (ii) for those directors who have served at least three years as of December 31, 2002, a catch-up stock option for 1,000 shares, issued at fair market value as of June 1, 2003.

Independent Directors appointed to the Board of Directors also receive an automatic NSO grant for that number of shares of Common Stock approved by the Board but not less than 2,500 nor more than 5,000 shares. To date, all directors have received an option grant of 2,500 shares of our Common Stock upon their election to our Board. The exercise price of this NSO is 85% of the fair market value of our stock as of the date of grant. The option is forfeitable if a director resigns within one year after election as a director. The Board of Directors has granted each of Donald A. Bliss, G.D. Madden, Matt Salmon and Mark

-10-

Scudder, an NSO for 2,500 shares of our Common Stock upon their election to our Board of Directors.

Members of the Board of Directors also have the option to accept shares of our Common Stock in lieu of directors fees. If this option is elected, we issue Common Stock on February 15 and August 15 of each year in payment of accrued director's fees for the preceding six month periods ending June 30 and December 31, respectively, at the closing market price for such shares as of the trading day prior to issuance.

COMMITTEES OF THE BOARD OF DIRECTORS

The Board of Directors has established four committees, which are authorized to act on behalf of the Board in their respective spheres: the Executive Committee, the Audit Committee, the Compensation Committee and the Nominating Committee. The Nominating Committee was established on February 6, 2003, to nominate directors for elections beginning in 2004. The responsibilities of each committee are described below.

EXECUTIVE COMMITTEE

The Executive Committee of the Board was established November 7, 2000. The Executive Committee is authorized to act on behalf of the Board of Directors when the Board of Directors is not in session. The members of the Executive Committee are Kevin P. Knight, Gary J. Knight, Donald A. Bliss, and Mark Scudder. The Executive Committee did not meet in 2002.

AUDIT COMMITTEE AND AUDIT COMMITTEE REPORT

The Audit Committee for 2002 was composed of Donald A. Bliss, G.D. Madden and Matt Salmon. Mr. Bliss served as Chairman of the Audit Committee. The Audit Committee is comprised of directors who meet the NASDAQ and Sarbanes-Oxley Act of 2002 Standards for independence. The Audit Committee met five (5) times during 2002. Each member of the Audit Committee attended at least 75% of the Audit Committee meetings during 2002. Since 1994, the Audit Committee has operated pursuant to a written charter detailing its duties. In October, 2002, the Audit Committee amended and restated its charter to comply with certain requirements of the Sarbanes-Oxley Act of 2002. The Audit Committee's Amended and Restated Charter is set forth in EXHIBIT 2, below. In performing its duties, the Audit Committee, as required by applicable Securities and Exchange Commission rules, issues a report recommending to the Board of Directors that our audited financial statements be included in our Annual Report on Form 10-K, and certain other matters, including the independence of our outside public accountants. The REPORT OF THE AUDIT COMMITTEE is set forth below.

THE AUDIT COMMITTEE REPORT SHALL NOT BE DEEMED TO BE INCORPORATED BY REFERENCE INTO ANY FILING MADE BY US UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES EXCHANGE ACT OF 1934, NOTWITHSTANDING ANY GENERAL STATEMENT CONTAINED IN ANY SUCH FILINGS INCORPORATING THIS PROXY STATEMENT BY REFERENCE, EXCEPT TO THE EXTENT WE INCORPORATE SUCH REPORT BY SPECIFIC REFERENCE.

REPORT OF THE
AUDIT COMMITTEE
OF
KNIGHT TRANSPORTATION, INC.

The Board of Directors of the Company has appointed an Audit Committee. The functions of the Audit Committee are focused on: (1) the adequacy of the Company's internal controls and financial reporting process and the reliability of the Company's financial statements; (2) the independence of the Company's external auditors; and (3) the Company's compliance with legal and regulatory requirements.

The Audit Committee meets periodically with management to discuss the adequacies of the Company's internal financial controls and the objectivity of its financial reporting. The Committee also meets with the Company's independent auditors.

For the fiscal year ending December 31, 2002, Donald A. Bliss, Chairman, G.D. Madden and Matt Salmon comprised the Audit Committee.

The directors who serve on the Audit Committee are all "independent" for purposes of the Sarbanes-Oxley Act of 2002 (the "Act") and the NASDAQ Stock Market listing standards. That is, none of the members have a relationship to the Company that would interfere with his independence from the Company and its management.

The Board of Directors has adopted a written charter setting forth the Audit Committee's functions and responsibilities. The Board of Directors adopted an Amended and Restated Charter to enhance the Audit Committee's functions and responsibilities in order to comply with certain provisions of the Act. A copy of the Audit Committee's Amended and Restated Charter may be found in Exhibit 2 to this Proxy Statement.

The Company retains independent public accountants who are responsible for conducting an independent audit of the Company's financial statements, in accordance with generally accepted accounting principles, and issuing a report thereon. In performing its duties, the Audit Committee has discussed the Company's financial statements with management and the Company's independent auditors and, in issuing this report, has relied upon the responses and information provided to the Audit Committee by each of them.

Management of the Company is primarily responsible for the Company's financial statements and the overall reporting process, including maintenance of the Company's system of internal controls. The independent auditors audit the annual financial statements prepared by management, and express an opinion as to whether those financial statements fairly present the financial position, results of operations, and cash flows of the Company in conformance with generally accepted accounting principles, and discuss with the Audit Committee any issues they believe should be raised.

For the fiscal year ending December 31, 2002, the Audit Committee:

(1) Reviewed and discussed the audited financial statements with management of the Company;

-12-

(2) Discussed with KPMG LLP, the independent auditors of the Company, the matters required to be discussed by Statement on Accounting Standards No. 61 (communications with Audit Committees); and

(3) Received the written disclosures and the letter from the Company's independent auditors (required by Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees) and has discussed with the Company's independent accountants, the matters relating to the auditors' independence from the Company.

Based upon the Audit Committee's review and discussion of the matters above, the Audit Committee recommends to the Board of Directors of the Company that the audited financial statements be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2002, filed with the Securities and Exchange Commission.

FISCAL 2002 AUDIT COMMITTEE:

G.D. Madden, Member
Matt Salmon, Member

COMPENSATION COMMITTEE

The Compensation Committee is composed entirely of directors who are not officers, employees or 10% shareholders of the Company. The Compensation Committee reviews all aspects of executive compensation and makes recommendations on such matters to the Board of Directors. The Compensation Committee also reviews and approves stock options granted by the Company. The Compensation Committee met formally once in 2002 to issue its Report on Executive Compensation. The Compensation Committee, by written action taken without a meeting, also approves stock option grants we propose to make to officers and employees. Additional information concerning the Compensation Committee, its members, Compensation Committee interlocks, and its REPORT ON EXECUTIVE COMPENSATION and the Performance Graph are set forth under "EXECUTIVE
COMPENSATION," below.

NOMINATING COMMITTEE

By action taken at the February 6, 2003, meeting of the Board of Directors, the Board established a Nominating Committee to recommend to the Board potential candidates for election to the Board of Directors for 2004 and thereafter. The members of the Nominating Committee are Randy Knight and Mark Scudder. As of the date of this Proxy Statement, the Nominating Committee has not held any meetings.

OTHER COMMITTEES

We do not maintain any other standing committees of the Board of Directors.

COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

Section 16(a) of the Securities Exchange Act of 1934 requires our directors and executive officers, and persons who own more than 10% of a registered class of our equity securities, to file with the Securities and Exchange Commission ("SEC") and the National Association of Securities Dealers Automated Quotation System ("NASDAQ") reports of ownership and changes in ownership of Common Stock and other equity securities of the Company. Officers, directors and greater than 10% beneficial owners are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file. Based solely upon a review of the copies of such reports furnished to the Company, or written representations that no other reports were required, we believe that during the 2002 fiscal year, all
Section 16(a) filing requirements applicable to our directors, executive officers and greater than 10% beneficial owners were complied with. Pursuant to the Sarbanes-Oxley Act of 2002, we will post copies of Section 16(a) forms our directors and executive officers file with the SEC on our website at www.knighttrans.com.

Except as set forth above, no stock appreciation rights (SARs) or other options were granted during the 2002 fiscal year to any of the Named Executive Officers.

The following table sets forth the information with respect to the exercise of stock options during the fiscal year ended December 31, 2002.

(1) In 2002, 2001 and 2000, compensation included in the category of "All Other Compensation" for each of the Named Executive Officers included Company contributions in the amount of $625, for each year, to the Knight Transportation, Inc. 401(k) Plan. The balance of compensation included in "All Other Compensation" represents the annual economic benefit derived from a $2,000,000 split-dollar life insurance policy maintained for each of the Knights, and a $1,000,000 policy maintained for Mr. Kohl, during 2002, which will be reimbursed to the Company upon termination or payment of the policy. In compliance with Section 402 of the Sarbanes-Oxley Act of 2002, as of July 30, 2002, the Company no longer makes premium payments under these split-dollar life insurance polices. To the extent any officer receives compensation in lieu of such premium payments, the Company reports such payments as compensation.

EMPLOYMENT AGREEMENTS

We currently do not have any employment contracts, severance or change-in-control agreements with any of our Named Executive Officers.

Upon Randy Knight's retirement as Chairman in 1999, we entered into a Consulting Agreement with Mr. Knight for $50,000 per year. The Consulting Agreement is terminable at any time by either party. Presently, consulting services are rendered by Randy Knight through a limited liability company controlled by Mr. Knight.

STOCK OPTION PLAN

We adopted in 1994 and currently maintain a stock option plan to enable directors, officers and certain key and critical line employees of the Company, including drivers and other employees, to participate in the ownership of the Company. This plan was amended and restated during 1998 (the "1998 Plan") and was approved by the Company's shareholders on May 13, 1998. In authorizing stock grants under the 1998 Plan, the Compensation Committee has sought to align the interests of employees with our shareholders and has sought to make stock grants to those key employees and operating personnel whose performance is important to our success. As of February 27, 2003, after giving effect to stock splits and the 2002 amendment to the 1998 Plan increasing the number of shares reserved for issuance by 300,000, we had 1,793,008 shares of our Common Stock subject to outstanding option grants and 456,525 shares of Common Stock were reserved for the issuance of future grants. Of the total number of issued and outstanding stock grants under the 1998 Plan, 89% have been made to employees and only 11% have been made to officers and directors. If Proposal No. 2 to approve the 2003 Plan is approved by shareholders, no further stock grants will be made under the 1998 Plan after May 31, 2003, and all future stock grants will be made exclusively under the 2003 Plan. SEE Item No. 2, "PROPOSAL TO APPROVE 2003 STOCK OPTION PLAN," above, for more information on the 2003 Plan.

401(k) PLAN

We also sponsor a 401(k) Plan (the "401(k) Plan"). The 401(k) Plan is a profit sharing plan that permits voluntary employee contributions on a pre-tax basis under section 401(k) of the Internal Revenue Code. Under the 401(k) Plan, a participant may elect to defer a portion of his compensation and have us contribute a portion of his compensation to the 401(k) Plan. We make a discretionary matching contribution. For 2002, our maximum contribution was $625 per participant. The 401(k) Plan's assets are held and managed by an independent trustee. Under the 401(k) Plan, eligible employees have the right to direct the investment of employee and employer contributions among several mutual funds. The 401(k) Plan also allows its participants to direct the trustee to purchase shares of our stock on the open market up to a maximum of 20% of their 401(k) Plan account balance. As of December 31, 2002, approximately 5% of all assets held by the 401(k) Plan were invested in our Common Stock. Our senior executives and certain key employees are not permitted to participate in the 401(k) Plan feature that allows them to purchase our Common Stock in their 401(k) Plan accounts.

Amounts we contribute for a participant vest over five years and are held in trust until distributed pursuant to the terms of the 401(k) Plan. An employee is eligible to participate in the 401(k) Plan if he has attained age 19 and completed 1,000 hours of service within a 12 month period. Distributions from participant accounts are not permitted before age 59-1/2, except in the event of death, disability, separation from service, or certain financial hardships.

COMPENSATION COMMITTEE, COMPENSATION COMMITTEE INTERLOCKS, REPORT ON EXECUTIVE COMPENSATION

THE COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION, AND THE PERFORMANCE GRAPH THAT FOLLOW SHALL NOT BE DEEMED TO BE INCORPORATED BY REFERENCE INTO ANY FILING MADE BY US UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES EXCHANGE ACT OF 1934, NOTWITHSTANDING ANY GENERAL STATEMENT CONTAINED IN ANY FILING INCORPORATING THIS PROXY STATEMENT BY REFERENCE, EXCEPT TO THE EXTENT WE INCORPORATE THIS REPORT AND GRAPH BY SPECIFIC REFERENCE.

The Compensation Committee is composed entirely of directors who are not officers, employees or 10% or greater shareholders of the Company. The Compensation Committee reviews all aspects of compensation of our executive officers and makes recommendations on compensation matters to the full Board of Directors. The Compensation Committee of the Board of Directors for 2002 was composed of G.D. Madden and Mark Scudder. Mr. Scudder served as Chairman of the Compensation Committee. SEE "CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS," below, for a description of transactions between us and members of the Board of Directors or their affiliates, and "CORPORATE GOVERNANCE - MEETINGS AND COMPENSATION OF THE BOARD OF DIRECTORS AND ITS COMMITTEES," above, for a description of compensation of the members of the Compensation Committee. The Compensation Committee also renders an annual report to the Board of Directors concerning the compensation of our executive officers.

The Compensation Committee of the Board of Directors has furnished the following Report on Executive Compensation:

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

Under the supervision of the Compensation Committee of the Board of Directors, the Board of Directors reviews the compensation of the Company's executive officers annually. The compensation program for the Company's executive officers is administered in accordance with a pay-for-performance philosophy to link executive compensation with the values, objectives, business strategy, management incentives, and financial performance of the Company.

Because the most senior executive officers of the Company each have substantial holdings of the Company's Common Stock, corporate performance directly affects these executive officers. The Committee believes that stock ownership by the Company's most senior executive officers aligns the interests of management with the interests of shareholders in the enhancing of shareholder value. With the exception of Mr. Timothy Kohl, Chief Financial Officer and Secretary, who is eligible for stock options and bonus awards, the Company's executive officers are compensated with a base salary only, with no bonus or short or long term incentives. With respect to Mr. Kohl and other executive officers without substantial holdings of the Company's Common Stock, the objectives of the Company's compensation program are to align, through the grant of stock options, executive and shareholder long-term interests by creating a strong and direct link between executive pay and shareholder return. The Company's stock option program is intended to enable executives to develop and maintain a significant, long-term stock ownership position in the Company's Common Stock. The Committee believes that the Stock Option Plan is an effective tool for accomplishing this objective.

In reviewing base salaries of senior management for 2002 and salary compensation for 2002-2003, including the salary of Mr. Kevin P. Knight, the Company's Chief Executive Officer, the Compensation Committee reviewed and considered (i) compensation information disclosed by similarly-sized publicly held truckload

-18-

motor carriers; (ii) the financial performance of the Company, as well as the role and contribution of the particular executive with respect to such performance; (iii) non-financial performance related to the individual executive's contributions; and (iv) the particular executive's stock holdings.

The Compensation Committee believes that the annual salaries of the Company's Chief Executive Officer and other executive officers are reasonable compared to similarly situated executives of other truckload motor carriers.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

COMPANY'S PURCHASE AND LEASE OF PROPERTIES

Our headquarters and principal place of business is located at 5601 West Buckeye Road, Phoenix, Arizona, on approximately 65 acres. We own approximately 57 acres and, as of December 31, 2002, leased approximately 8 acres from Randy Knight, a director and principal shareholder of the Company. The property we lease from Randy Knight includes terminal and operating facilities. We made total payments of approximately $83,000 to, or on behalf of, Total Warehousing and Randy Knight for the year ended December 31, 2002. Randy Knight owns a 50 percent interest in Total Warehousing; the balance is owned by an unaffiliated party.

In March 1999, we exercised our option to extend our lease with Randy Knight for five (5) years, until April 30, 2004. We have an additional option to extend the lease term for an additional five (5) years. The current monthly base rent is $6,700. Under the lease, base rent increases by 3% on the first day of each option term, and the third anniversary of the commencement date of each option term. In addition to base rent, the lease requires us to pay our share of all expenses, utilities, taxes and other charges. Under the lease, the Company and Total Warehousing will continue to use portions of the premises jointly. We have granted Randy Knight access and utility easements over our owned and leased properties. The purchase and lease agreements between us and Randy Knight include cross-indemnities relating to liabilities and expenses arising from the use and occupancy of the property by the parties to the agreements.

We and Total Warehousing from time to time provide services to each other. Total Warehousing provided us with general warehousing services and we paid $15,000 to Total Warehousing for these services for the year ended December 31, 2002.

OTHER INVESTMENTS AND TRANSACTIONS WITH AFFILIATES

We have adopted a policy that transactions with affiliated persons or entities will be on terms no less favorable to us than those that could be obtained from unaffiliated third parties on an arm's length basis, and that any such transaction must be reviewed by our Independent Directors. We periodically examine investment opportunities in areas related to the truckload carrier business. Our investment strategy is to add to shareholder value by investing in industry-related businesses that will assist us in strengthening our overall position in the transportation industry, minimize our exposure to start-up risk and provide us with an opportunity to realize a substantial return on our investment.

-22-

In April 1999, we acquired a 17% interest in Concentrek, Inc. ("Concentrek"), formerly known as KNGT Logistics, Inc., with the intent of investing in the non-asset transportation business. Our investment in Concentrek was approved by a majority of our Independent Directors. We hold non-voting Class A Preferred Stock in Concentrek which is preferred in the event of liquidation, dissolution, sale or merger and with respect to dividends over all other classes of stock, including stock held by members of the Knight family. We have preferential rights if Concentrek issues additional shares and limited voting rights with respect to any merger, consolidation, sale of substantially all of Concentrek's assets, and certain other major corporate events. We have loaned a total of $3.4 million to Concentrek to fund start-up costs. These loans are evidenced by two promissory notes. One note evidences a loan by the Company under a wholly owned limited liability company for $824,500 that is convertible into Concentrek's Class A Preferred Stock and is secured by a first lien on Concentrek's assets. The other note evidences a loan by the Company directly to Concentrek for an additional $2.6 million that is secured by a first lien on Concentrek's assets. Kevin Knight, Gary Knight, Keith Knight and Randy Knight, who collectively own 34% of our issued and outstanding stock, and who are also investors in Concentrek along with other unrelated Concentrek shareholders, have personally guaranteed repayment of the $2.6 million note. The notes are on parity with respect to their security. Our loans to Concentrek have priority over the loans made by the Knights described below. Our investment has been structured to limit our exposure to Concentrek start-up losses and business risk. SEE "MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - OFF BALANCE SHEET ARRANGEMENTS," in our Form 10-K for the year ended December 31, 2002.

Other investors in Concentrek include Randy, Kevin, Gary and Keith Knight, who collectively own 43% of Concentrek's issued and outstanding stock, and through the same limited liability company affiliate through which we invested, Randy, Kevin, Gary and Keith Knight have collectively loaned to Concentrek the sum of $4.5 million. This loan is evidenced by a promissory note convertible into Concentrek Class B Preferred Stock to fund Concentrek's start-up costs.

In November 2000, we acquired a 19% interest in Knight Flight Services, LLC ("Knight Flight"), which acquired and operates a Cessna Citation 560 XL jet aircraft. The aircraft is leased to Pinnacle Air Charter, L.L.C., an unaffiliated entity, which leases the aircraft on behalf of Knight Flight. The cost of the aircraft to Knight Flight was $8.9 million. We invested $1.7 million in Knight Flight to assure access to charter air services for the Company. We have a priority use right for the aircraft and are not obligated to make additional capital contributions to Knight Flight. The remaining 81% interest in Knight Flight is owned by Randy, Kevin, Gary and Keith Knight, who have personally guaranteed the balance of the purchase price and agreed to contribute any capital required to meet any cash short falls. Under the Knight Flight Operating Agreement, losses are allocated first to Kevin Knight, Gary Knight and Keith Knight. The acquisition of our interest in Knight Flight was approved by a disinterested majority of our Board of Directors. We believe that our interest in Knight Flight allows us to obtain any access to needed charter air services for Company business at prices equal to or less than is available from unrelated charter companies. Knight Flight also makes the aircraft available for charter to third parties through a licensed aircraft charter company.

Randy Knight retired as an officer of the Company on July 31, 1999, and since then has acted as a consultant to us for which we paid him fees of $50,000 per year. The consulting agreement is terminable at the will of either party. The Board of Directors has approved this arrangement.

We paid approximately $50,000 during 2002 for key employees' life insurance premiums. The life insurance policies provide for cash distributions to the beneficiaries of the policyholders upon death of the key employee. We are entitled to receive the total premiums paid out on the policies at distribution prior to any beneficiary distributions. In compliance with Section 402 of the Sarbanes-Oxley Act of 2002, as of July 30, 2002, the Company no longer makes premium payments under these split-dollar life insurance polices. To the extent

-23-

any officer receives compensation in lieu of such premium payments, the Company reports such payments as compensation.

The Knight family has been involved in the transportation business for a number of years and members of the families of Kevin Knight, Gary Knight, Keith Knight, and Randy Knight have been employed by us since our inception and are employed on the same terms and conditions as other non-related employees. During 2002, we employed and compensated in excess of $60,000 (total compensation) seven individuals who are related to our principal shareholders and senior executive officers. The aggregate total compensation paid to these seven individuals in 2002 was $541,700.

During 2002, we retained Scudder Law Firm to perform certain legal services on our behalf. Mark Scudder, a member of our Board of Directors, is also a member of Scudder Law Firm and performed legal services on our behalf. We intend to continue the use of Scudder Law Firm during 2003. Amounts paid to the Scudder Law Firm in 2002 were less than $60,000.

SHAREHOLDER PROPOSALS

The Board of Directors will consider proposals from shareholders for nominations of directors to be elected at the 2004 Annual Meeting of shareholders that are made in writing to the Secretary of the Company, are received at least ninety (90) days prior to the 2004 Annual Meeting, and contain sufficient background information concerning the nominee to enable a proper judgment to be made as to his or her qualifications, as more fully provided in our Articles of Incorporation and Bylaws.

Proposals of shareholders as to other matters intended to be presented at the 2004 Annual Meeting must be received by the Company by December 6, 2003, to be considered for inclusion in our Proxy Statement and form of proxy relating to such meeting. Proposals should be mailed via certified mail, return receipt requested, and addressed to Timothy M. Kohl, Secretary, Knight Transportation, Inc., 5601 West Buckeye Road, Phoenix, Arizona 85043.

OTHER MATTERS

The Board of Directors does not intend to present at the Annual Meeting any matters other than those described herein and does not presently know of any matters that will be presented by other parties.

ARTICLE 1.
HISTORY AND PURPOSE

1.1 HISTORY.

Knight Transportation, Inc. (the "Company" or "Knight") has maintained a stock option plan for the benefit of officers, employees and directors since 1994. Grants under all prior plans have been broad-based and have been designed to align the interest of employees of the Company receiving grants with those of the Company's shareholders. On February 6, 2003, the Board of Directors approved the termination of all further stock grants under the Company's Amended and Restated Stock Option Plan adopted February 10, 1998 (the "1998 Plan"), effective as of May 31, 2003, subject to the Company's shareholders approving this 2003 Stock Option Plan. As amended, the 1998 Plan permits any issued and outstanding option grants to continue in force and effect, in accordance with their terms, but no further options or stock grants will be made under the 1998 Plan, if the Company's shareholders approve this Plan. The Board also adopted, effective as of June 1, 2003, the Knight Transportation, Inc. 2003 Stock Option Plan (the "Plan"), subject to approval by the Company's shareholders at its annual meeting to be held in May, 2003.

This document sets forth the terms of the Company's 2003 Stock Option Plan, including, without limitation, the number of shares that are reserved for grants under the Plan and all other terms and conditions applicable to the Plan. This Plan and any options or rights granted hereunder, are subject to approval by the Company's shareholders within 12 months of February 6, 2003. 1.2 PURPOSE. The Plan has been adopted to: (a) provide certain key employees of the Company (as defined below) with an opportunity to purchase the common stock of Knight as an incentive to continue employment with the Company and to work for the long-term growth, development, and financial success of the Company; (b) attract qualified independent directors by providing the automatic grant of certain nonqualified stock options to independent directors upon their appointment to the Company's Board of Directors; and (c) attract, motivate, and retain the services of critical employees of the Company and its subsidiaries and reward such employees by the issuance of Stock Grants so that these employees will contribute to and participate in the long-term performance of the Company.

ARTICLE 2.
DEFINITIONS

2.1 DEFINED TERMS. The following terms shall have the meanings set forth below, unless context otherwise requires:

-2-

for Stock Grants under this Plan, 50,000 shares of Stock are reserved for Stock Grants made under the Independent Directors Plan set forth in Article 6. The balance of the Shares are reserved for Stock Grants awarded under any other provision of this Plan; provided, however, that in no event shall the aggregate number of shares of Stock subject to all Stock Grants made under this Plan since inception exceed 1,000,000 shares of Stock, adjusted as described in Section 3.2, below.

3.2 ADJUSTMENT TO SHARES. The aggregate number of shares of Stock which may be issued pursuant to Stock Grants made under this Plan shall be automatically adjusted, without further action by the Board or the shareholders of the Company, to reflect changes in the capitalization of the Company, such as stock dividends, stock splits, reverse stock splits, subdivisions, reorganizations or reclassification, or any similar recapitalization that affects or modifies the number of shares of Stock issued and outstanding at any time. The adjustment of shares of Stock reserved for Stock Grants under this
Section shall not cause shares of Stock subject to a Stock Grant Agreement to be automatically adjusted, unless the Stock Grant Agreement specifically requires such an adjustment.

3.3 NUMBER OF STOCK GRANTS; PARTIAL EXERCISE. More than one Stock Grant may be made to the same Participant, and Stock Grants may be subject to partial exercise, as the Committee may in its discretion determine. If any Stock Grant made under this Plan expires or is terminated without being exercised, or after being partially exercised, the shares of Stock allocated to the unexercised portion of a Stock Grant shall revert to the pool of shares reserved in Section 3.1 and shall again be available for Stock Grants made under this Plan.

ARTICLE 4.
PLAN ELIGIBILITY

4.1 GENERAL. The Committee, subject to the following limitations, shall from time to time designate from among the Company's employees those persons who will be Participants in this Plan, subject to the following rules:

4.2 STOCK OPTION PLAN. Only full-time employees of the Company, who, in the sole judgment of the Committee, (i) are qualified by position, training, ability, and responsibility to contribute substantially to the progress of the Company; (ii) have a material, positive effect on the results of the operations of the Company; or (iii) are key employees or critical line employees (as determined by the Committee, in its discretion), shall be eligible to participate in the Stock Option Plan described in Article 5.

4.3 INDEPENDENT DIRECTORS PLAN. Independent Directors of the Company shall be automatically eligible to participate in the Independent Directors Plan described in Article 6.

ARTICLE 5.
STOCK OPTION PLAN

5.1 AWARD OF STOCK GRANT. The Committee may award Stock Grants to a Participant in the form of Stock Options, including, without limitation, "ISOs," "NSOs," or Restricted Stock Grants under this Article 5, or any combination thereof. At the time a Stock Grant is awarded under this Article 5, the Committee shall designate the number of shares of Stock subject to the grant and indicate whether such grant is an ISO, NSO or a Restricted Stock Grant.

5.2 ISOS. The following rules shall apply to any Stock Options granted as ISOs, in addition to any other provisions of this plan that may be applicable.

-3-

(a) FAIR MARKET VALUE OF ISO. The aggregate fair market value of Stock subject to an ISO granted under this Article 5 (determined without regard to this Section 5.2) exercisable for the first time by any Participant during any calendar year (under all plans of the Company) shall not exceed $100,000. The preceding sentence shall be applied by taking ISOs into account in the order in which they were granted hereunder. If any ISO is granted that exceeds the limitations of this Section 5.2 at the first time it is exercisable, it shall not be invalid, but shall constitute, and be treated as, an NSO to the extent of such excess. For purposes of this Plan, the fair market value of the Stock subject to any ISO shall be determined by the Committee without regard to any restriction other than a restriction which, by its terms, will never lapse.

(b) DISPOSITION OF ISO STOCK. No Stock issued in connection with a Participant's exercise of an ISO may be disposed of by the Participant within two years from the date the option is granted nor within one year after the date such Stock is issued to the Participant and be eligible for treatment as an ISO; provided, however, unless otherwise provided in the Stock Grant Agreement, these holding periods shall not apply if the Stock Option is exercised after the death of a Participant by the estate of such Participant, or by a person who acquired the right to exercise such option by bequest or inheritance or by reason of the death of a deceased Participant.

(c) INSOLVENT PARTICIPANTS. A disposition of Stock described in
Section 422(c)(3) of the Code, which was acquired pursuant to the exercise of an ISO, shall not constitute a disposition of Stock in violation of Section (b) of this Article 5.

(d) CONSTRUCTION. Any ISO granted under this Plan shall be construed to meet the requirements of Section 422 of the Code and the regulations thereunder.

5.3 OPTION OR PURCHASE PRICE.

(a) Each Stock Option shall state the exercise price of the option, which, in the case of an ISO, shall not be less than 100% of the fair market value of the optioned Stock on the date the ISO is granted, as provided below. Any Restricted Stock Grant shall state the price at which the Restricted Stock may be purchased. In the case of a Participant who, at the time the ISO is granted, owns shares of Stock possessing more than 10% of the total combined voting power of all classes of stock of the Company (or any parent or subsidiary), the exercise price of such ISO shall be not less than 110% of the fair market value of Stock on the date the option is granted, and, in no event, shall such option be exercisable after the expiration of five years from the date such option is granted.

(b) The exercise price of an NSO, the purchase price under a Restricted Stock Grant, or the exercise price of any Stock Option granted to a director under Article 6 shall not be less than 85% of the fair market value of a share of the Stock as of the date of grant. For purposes of this Plan, the fair market value of a share of Stock shall equal the mean of the highest bid and lowest selling prices for such stock on the day preceding the date of grant, as reported by the National Association of Securities Dealers Automated Quotation System (NASDAQ) (National Market). If for any reason the Company's Stock is not publicly traded on a national securities market or not listed on NASDAQ, the Committee shall evaluate all factors which the Committee believes are relevant in determining the fair market value of a share of Stock and, the Committee, in good faith and exercising its business judgment, shall establish the fair market value of the Stock as of the date an option is granted.

5.4 LIMITATION ON PERIOD IN WHICH TO GRANT OR EXERCISE OPTIONS. No ISO shall be granted under this Plan more than 10 years after the earlier of (i) the date the Plan is initially adopted by the Board or (ii) the date the Plan is approved by the shareholders of the Company. Any Stock Grant, other than an ISO, made under the Plan may be exercised within any reasonable term and may be granted any time prior to the termination or expiration of the Plan. In no event shall an ISO granted under this Plan be exercised after the expiration of 10

-4-

years from the date such ISO is granted. Any provision of this Plan to the contrary notwithstanding, the Committee may, in its sole discretion, grant any Participant an NSO which, if provided in the Stock Grant Agreement, may be exercised after the termination of the Participant's employment with the Company.

ARTICLE 6.
INDEPENDENT DIRECTORS PLAN

6.1 AUTOMATIC GRANT; ANNUAL COMPENSATION; FORFEITURE. Any Independent Director appointed to the Board after September 1, 1995, shall automatically receive an NSO for 2,500 shares of the Company's Stock; the exercise price of such option shall be 85% of the fair market value of the Company's stock as of that date. In addition, for calendar years beginning after December 31, 2002, Independent Directors will receive an NSO for 500 shares, as described in the next sentence, for each calendar year an Independent Director is a Director. Such option grant shall be made on June 1 of each calendar year, beginning June 1, 2003, and continuing on the same day of each year thereafter, for each person who is an Independent Director on that date. In addition, each Independent Director who, as of December 31, 2002, has served as an Independent Director for at least three calendar years, shall also be entitled to an NSO grant of 1,000 shares for service previously rendered to the Company; such option shall be issued on June 1, 2003 and the exercise price shall be the fair market value of the Company's stock as of that date, as provided in Section 5.3(b) above. Any NSO granted to an Independent Director (other than the NSO grant for 1,000 shares described in the preceding sentence) will be forfeited if the director resigns within one year of the date of the grant of such NSO.

6.2 TERMINATION OF INDEPENDENT DIRECTOR OPTION. Except as otherwise provided in any written agreement between the Company and the Independent Director, any NSO granted hereunder will expire on the earlier of (i) ten years after the date of grant; (ii) one year after such independent director terminates his services as a director of the Company; (iii) the expiration date stated in the Stock Grant Agreement (as this term is defined in the Plan); or
(iv) any earlier date provided in this Article 6. An Independent Director may also elect to receive the Director fees in Stock of the Company.

6.3 HOLDING PERIOD. Any Stock Option made to an Independent Director may not be exercised for at least seven months following the date such Stock Option is granted. 6.4 EXISTING OPTIONS. All Stock Options granted by the Company to Independent Directors, including options issued prior to the date hereof, shall be subject to the terms and conditions of this Article 6.

6.5 PAYMENT OF DIRECTORS FEES IN STOCK. With the consent of the Independent Director, the Company may pay the director's fees due any Independent Director in Stock of the Company. In such event, the Company shall grant to each consenting Independent Director on February 15 and August 15 of each calendar year the number of shares of Company Stock (disregarding any fraudulent shares) equal to the director's fees due such Independent Director as of the preceding December 31 and June 30, respectively, based on the fair market value of the Company Stock, as provided in Section 5.3(b) above, as of the trading day preceding each such February 15 and August 15.

ARTICLE 8.
GENERAL PROVISIONS

8.1 GRANT AGREEMENT. Each Stock Grant made under this Plan shall be evidenced by a Stock Grant Agreement and shall be executed by the Company and the Participant. The Stock Grant Agreement shall contain any terms and conditions required by this Plan and such other terms and conditions as the Committee, in its sole discretion, may require, including, without limitation, restrictions on the transferability of any Stock which are not inconsistent with the Plan.

8.2 MERGERS OR CONSOLIDATIONS. If the Company at any time dissolves or undergoes a reorganization, including, without limitation, a merger or consolidation with any other organization, in any manner or form whatsoever, and the Company is not the surviving organization and the surviving organization does not agree to assume the options granted pursuant to this Plan or to substitute options in place thereof, the Stock Grants made under this Plan may be terminated, subject to the procedures set forth in this Article 8. Prior to any termination of this Plan or the Stock Grants made hereunder, each Participant holding an outstanding Stock Grant not yet exercised shall be notified of such termination and shall be provided a reasonable period of not less than fifteen (15) days in which to exercise such Stock Option prior to its termination, to the extent such option is then exercisable. The Committee may, in its sole discretion, prescribe such terms and conditions as the Committee deems appropriate and authorize the exercise of such Stock Grants with respect to all shares covered in the event of a merger or consolidation. Any Stock Grant not exercised in accordance with such prescribed terms and conditions shall terminate as of the date specified by the Committee, and simultaneously, the Plan itself shall be terminated without further order of the Company or the Board of Directors.

8.3 TERMINATION OF EMPLOYMENT. Except as provided in Sections 5.4, 6.1 or as otherwise permitted by this Plan (or any Stock Grant Agreement), any Stock Grant made pursuant to this Plan shall immediately terminate upon a Participant's termination of employment with the Company, unless such termination of employment occurs by reason of the death or retirement (including early retirement, if approved by the Committee) of the Participant, or on account of the permanent and total disability of the Participant (as such term is defined in Section 22(e)(3) of the Code and the regulations therein). Upon retirement (including early retirement), a Participant (or the administrator or conservator of the Participant's estate) may, subject to Section 5.4(a) of the Plan, exercise any Stock Grant in full within three months of retirement or, if the Participant retired or terminated employment on account of "permanent and total disability" (as that term is defined in Section 22(e)(3) of the Code), within one year of retirement. If a Participant dies while in the employment of the Company or within three months after retirement, the Participant's personal representative of his or her estate or other person who acquired the right to exercise such Stock Grant by bequest or inheritance or by reason of the death of the deceased Participant may, subject to Section 5.4 of the Plan or any contrary provision of the Stock Grant Agreement, exercise the option in full within one year from the date of the Participant's death, unless such exercise period would disqualify such ISO as an incentive stock option under Section 422 of the Code, but the Committee, with the consent of the Participant, may waive this limitation.

8.4 PAYMENT FOR STOCK. The exercise price for any shares of Stock acquired through the whole or partial exercise of any Stock Grant shall be paid in full in cash or immediately available funds, or in Stock with a current market value equal to all or a part of the exercise price, or both.

8.5 COMPLIANCE WITH APPLICABLE LAWS AND REGULATIONS. Stock Grants made under this Plan shall contain such provisions with respect to compliance with applicable federal and state law as the Committee, with the advice of the Company's counsel, may deem appropriate, including, without limitation, any provision necessary to comply with state or federal securities laws.

-7-

8.6 NO RIGHT TO EMPLOYMENT. Designation of an employee as a Participant in this Plan for any purpose shall not confer on the employee the right to continue in the employment of the Company or any right to receive a Stock Grant for any Plan Year.

8.7 TAXES. A Participant shall be responsible for paying any taxes with respect to a Stock Grant. The Company is hereby authorized to deduct any taxes that may be applicable from the dollar value of any Stock Grant to a Participant, including, without limitation, FICA or FUTA, and the Company may effect any such deduction by reducing the number of shares acquired upon the exercise of Stock Grants by the amount of such FICA or FUTA tax liability, or may make other reasonable arrangements for the payment of any such tax liability.

8.8 EXPENSES. All expenses incurred in connection with the administration of this Plan shall be borne by the Company, except as any Stock Grant Agreement may otherwise provide.

8.9 UNFUNDED BENEFITS. Nothing in this Plan shall be construed as requiring the Company to establish a trust or to fund this Plan, or to create a trust of any kind or any fiduciary relationship between the Company and any Participant, employee or Beneficiary.

8.10 TRANSFERABILITY. Except as otherwise expressly permitted by this Plan, no Stock Grant made under this Plan shall be transferable by the Participant other than by will or by the laws of descent and distribution. During a Participant's lifetime, a Stock Grant made hereunder shall be exercisable only by the Participant and only if at all times during the period of time beginning on the date the Stock Grant is made and ending on the day three months (or one year, in the case of an employee or Independent Director who retires on account of becoming "permanently and totally disabled" within the meaning of that term under section 22(e)(3) of the Code) before the date of exercise of such Stock Grant, such Participant was an employee or director of the Company (or a corporation or a parent corporation or subsidiary corporation of a corporation assuming an option in a transaction to which section 424(a) of the Code applies).

8.11 EXPIRATION DATE OF PLAN. If not earlier terminated, this Plan shall expire on February 5, 2013. In no event shall any Stock Option be granted under this Plan after February 5, 2013. In no event shall any ISO be granted under this Plan after February 5, 2013.

8.12 CORPORATE ACTION. The issuance of a Stock Grant pursuant to this Plan shall not affect in any way the right or power of the Company to make adjustments, reclassifications, reorganizations, or changes of any kind to its capital or business structure or to merge, consolidate, dissolve, liquidate, sell or transfer all or any part of its business or assets.

8.13 RIGHTS AS A SHAREHOLDER. A Participant shall have no rights as a shareholder of the Company with respect to any shares of Stock subject to a Stock Grant made hereunder until the date of the issuance of a stock certificate to the Participant for such shares pursuant to such Stock Grant. Except as provided in Section 3.2, no adjustment shall be made for dividends (ordinary or extraordinary, whether in cash, securities, or other property) or distributions or other rights for which the record date precedes the date a stock certificate is issued to a Participant upon exercise of a Stock Grant.

8.14 INVESTMENT PURPOSE. Unless the Stock received pursuant to a Stock Grant issued under this Plan is registered with the Securities and Exchange Commission, each Stock Grant is subject to the condition that the issuance of the Stock Grant and any Stock issued upon exercise of the Stock Grant is for investment purposes only, and not with a view to the subsequent resale or distribution of such Stock, unless such Stock is registered under the Securities Act of 1933, as amended, or an exemption from registration is available.

-8-

8.15 INVESTMENT LETTER. Any Participant exercising a Stock Grant shall, as a condition to such exercise, execute and deliver to the Company an investment letter in such form as the Board of Directors or the Committee, with the advice of the Company's legal counsel, may from time to time require.

8.16 TERMINATION OR AMENDMENT OF THE PLAN. The Board may terminate, suspend, discontinue, modify or amend this Plan in any respect whatsoever, except that, without approval of the shareholders of the Company, no such revision or amendment shall change the number of shares of Stock of the Company subject to the Plan, change the designation of the class of employees eligible to receive options, decrease the price at which options may be granted or remove the administration of the Plan from the Committee. The preceding sentence notwithstanding, the Company may not terminate this Plan with respect to any issued and outstanding Stock Grant unless it gives the Participant notice of termination and not less than 15 days in which to exercise such Stock Grant, but only if such Stock Grant is then exercisable.

8.17 APPLICATION OF FUNDS. The proceeds received by the Company from the sale of shares of Stock pursuant to the exercise of Stock Grants shall be used for general corporate purposes. 8.18 OBLIGATION TO EXERCISE GRANT. A Stock Grant made hereunder shall impose no obligation on the Participant to exercise such grant.

8.19 APPROVAL OF SHAREHOLDERS; TERMINATION OF PLAN. This Plan, shall be effective as of June 1, 2003, subject to the approval of the shareholders of the Company, which approval must occur within the period beginning 12 months before and ending 12 months after February 6, 2003. The Committee may cause Stock Grants to be made under the Plan, subject to the Plan being approved by the Company's shareholders within the period described above.

8.20 GOVERNING LAW. The Plan shall be governed by and construed under the laws of the State of Arizona.

IN WITNESS WHEREOF, the foregoing Plan was approved by the Board of Directors on February 6, 2003, and is executed by the undersigned officers of the Company, each being duly authorized to do so.

EXHIBIT 2

KNIGHT TRANSPORTATION, INC.
AMENDED AND RESTATED AUDIT COMMITTEE CHARTER


AMENDED AND RESTATED
CHARTER OF THE AUDIT COMMITTEE
OF
THE BOARD OF DIRECTORS
OF
KNIGHT TRANSPORTATION, INC.

OCTOBER 1, 2002

RECITALS

In June 1994, the Board of Directors of Knight Transportation, Inc. (the "Company") appointed an Audit Committee, and that committee, since July 26, 1994, has maintained a written Charter specifying its duties.

On December 14, 1999, the Securities and Exchange Commission (the "Commission") issued Release No. 34-42231 (the "NASDAQ Release"), amending the rules applicable to the qualification and responsibility of directors participating on the audit committees of NASDAQ traded companies. On December 22, 1999, the Commission issued Release No. 34-42266 (the "SEC Release") amending, among other rules, the rules applicable to audit committees for all publicly traded companies.

Congress enacted the Sarbanes-Oxley Act of 2002 on July 30, 2002, which, among other things, amended certain laws and regulations applicable to audit committees of companies subject to the reporting requirements pursuant to
Section 13 (a) or 15(d) of the Securities Exchange Act of 1934.

The Board of Directors of the Company (the "Board") believes that it is appropriate to amend and restate the Charter of the Audit Committee of the Board of Directors of Knight Transportation, Inc. (the "Charter") to comply with the applicable provisions of the NASDAQ Release, the SEC Release and the Sarbanes-Oxley Act of 2002. Accordingly, the Charter is hereby amended and restated, in its entirety, as follows, effective as of October 1, 2002, to reflect the directives of the Company's Board.

CHARTER

1. PURPOSE OF AUDIT COMMITTEE. The purpose of the Audit Committee is to provide independent and skilled guidance to the Board in fulfilling its responsibility to ensure the fairness and accuracy of the Company's financial statements; to ensure the existence of appropriate internal financial controls; to ensure the independence of the independent public accounting firm engaged to audit the Company's financial statements (the "external auditors"); to render the reports required of the Audit Committee pursuant to Item 306 of Regulation S-K; and to allow the Company to make the disclosures required by Item 7(d)(3) of Schedule 14(A) and related Commission regulations.

2. QUALIFICATIONS OF AUDIT COMMITTEE. The Audit Committee shall consist of not less than three directors nor more than five directors, each of whom shall not accept any consulting, advisory, or other compensatory fee from the Company or be affiliated with the Company or any of its subsidiaries, and qualifies as an "independent director" as defined by Rule 4200 of the NASDAQ Stock Market, Inc.'s listing requirements, unless exceptional circumstances exist that, under NASDAQ listing requirements, would allow the Audit Committee to include one non-independent director member, who may not be either a current employee or immediate family member of a current employee. Each member of the Audit Committee shall be able to read and understand financial statements, including the Company's balance sheet, income statement, and cash flow statement. Additionally, at least one member of the Audit Committee shall be a "financial expert" who, in accordance with Securities and Exchange Commission rules, by education and experience as a public accountant or auditor or a principal financial officer, comptroller, or principal accounting officer, or from a position involving similar functions and has, in the judgment of the

(2) the effect of significant accounting policies in controversial or emerging areas for which there is a lack of authoritative guidance or consensus; (3) the process used by management in formulating particularly sensitive accounting estimates, and the basis for the auditors conclusions regarding the reasonableness of those estimates; and (4) disagreements with management, if any, over the application of accounting principles, the basis for management's accounting estimates, and the disclosures in the Company's financial statements);

(n) Recommend annually the selection and engagement of the Company's external auditors and review their fees and the proposed scope and plan of the annual audit;

(r) Review the performance of the Company's Chief Financial Officer and Controller;

(s) Review any difficulties any external auditor may have encountered with respect to performance of an audit, including, without limitation, any restrictions placed upon the scope of the audit on access to information, or any changes in the proposed scope of the audit;

(t) Provide, as part of the Company's proxy filed pursuant to Regulation 14A or 14C, as applicable, the report required by Item 306 of Regulation S-K, and cause a copy of that report to be included annually in the Company's proxy solicitation materials;

(u) Review any and all complaints received by the Company regarding accounting, internal accounting controls or auditing matters and determine in its good faith business judgment the proper course of action to be taken by the Audit Committee and the Company with respect to each individual complaint received, including conducting investigations and taking corrective action, to the extent necessary; and

4. ACCESS TO INFORMATION. In order to perform its obligations, the Audit Committee shall have unrestricted access to all relevant internal and external Company information and to any officer, director or employee of the Company.

5. COMPLAINTS, EMPLOYEE ACCESS TO AUDIT COMMITTEE.

(a) The Audit Committee shall establish a procedure for the receipt, retention and treatment of complaints received by the Company and Audit Committee on issues regarding accounting, internal accounting controls or auditing matters, and the confidential anonymous submission by employees of issues or concerns regarding questionable accounting or auditing matters.

(b) Any person employed by the Company and any of the Company's independent contractors will have access to the Audit Committee to report any matter which such person believes would be of interest to the Audit Committee or of general concern to the Audit Committee or the Board. Contacting a member of the Audit Committee to report any irregularity, questionable activity, or other matter will not subject the person making the report to discipline.

6. FREQUENCY OF MEETINGS. The Audit Committee will meet each quarter prior to the release of the Company's earnings statements to review the earnings release. In addition, the Audit Committee will convene if a meeting is noticed by its Chairman, any member of the Audit Committee, any member of the Board, the Chief Financial Officer, or the Chief Executive Officer.

7. ACCESS TO LEGAL COUNSEL. The Audit Committee, at its request, shall have access to the Company's outside legal counsel, and, if requested, to its own independent legal counsel. The Company will pay for the cost of any such legal counsel.

8. MEETING PROCEDURES.

(a) Members of the Audit Committee shall endeavor to attend all meetings of the Committee. The Audit Committee may meet telephonically or in person and may take action, with the written consent of all members. A majority of the Audit Committee will constitute quorum for all purposes.

(b) Written minutes will be maintained for each meeting of the Audit Committee.

(c) The Audit Committee, at least once a year, will meet privately with the Company's external and internal auditors, and no representative of the Company's management shall attend such meetings.

9. OTHER DUTIES. The Audit Committee will perform such other duties as the Board may assign to it.

10. LIMITATION OF AUDIT COMMITTEE DUTIES. The Audit Committee is not an investigative committee of the Board and shall have no investigative duties, unless expressly assigned to the Audit Committee by the Board. The Audit Committee will exercise its business judgment in performing its duties under this Charter, including the duties outlined in Paragraph 3, and may emphasize and prioritize those duties and responsibilities set forth above which the Committee, in its discretion and judgment, believes are the most important, given the particular circumstances. The external auditors shall remain ultimately accountable to the Company's Board and the Audit Committee, as the designated representatives of the Company's shareholders. Accordingly, it is not the duty of the Audit Committee to undertake the audit of the Company itself, to plan the audit, or to undertake any of the responsibilities of the Company's internal or external auditors. The Audit Committee is not required to follow the procedures required of auditors in performing reviews of interim financial

statements of audited financial statements. In performing its functions, the Audit Committee may rely upon information provided to it by management, by the Company's internal and external auditors, or by legal counsel. This Charter imposes no duties on the Audit Committee or its members that are greater than those duties imposed by law upon a director of an Arizona corporation under
Section 10-830 of the Arizona Revised Statutes or upon a director under applicable Federal law, including the Sarbanes-Oxley Act of 2002. If any claim is asserted against the Audit Committee, any of its members, or the Company by a shareholder or any other person, nothing in this Charter shall be construed to limit or restrict any defense available to the Audit Committee, to any of its members, or to the Company.
