                                 PROXY STATEMENT

     This Proxy  Statement is furnished in connection  with the  solicitation of
proxies from the shareholders of Knight Transportation,  Inc. (the "Company") to
be voted at the Annual Meeting of Shareholders (the "Annual Meeting") to be held
on May 9, 2001. 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  FOR the  Director  Nominees  named  below,  FOR the
Amendment to the Articles of Incorporation  clarifying the Amendment  adopted at
the 2000 Annual  Meeting,  and FOR the  ratification  of the selection of Arthur
Andersen LLP as the Company's independent public accountants for 2001. The Proxy
Statement,  proxy card,  and the Company's  Annual Report on Form 10-K was first
mailed on or about  April 5,  2001,  to  shareholders  of record at the close of
business on March 23, 2001 (the "Record Date").

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 the address of the Company,  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

     The Company 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 the outstanding common stock of the Company. Proxies will be solicited
by mail,  and may be  solicited  personally  by  directors,  officers or regular
employees of the Company, who will not be compensated for their services.

VOTING SECURITIES OUTSTANDING

     As of March 23, 2001,  there were  approximately  15,384,760  shares of the
Company's 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 will be 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 the Company's 2000 Annual Report to  Shareholders  that
was mailed on or about  April 5, 2001,  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 the  Company.  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 four directors are to be elected,  the shareholder may cast 400 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 two or more candidates for
director.  The nominees for director who receive the most votes will be elected.
Under  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  nine  (9)  directors  are up for  election  in  three  (3)  classes.  If a
shareholder has 100 shares,  the shareholder may cast 900 votes,  with 300 votes
to be cast in each of the three classes. 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.

the  Company's  Annual  Meeting  of  Shareholders  to be  held  on May 9,  2001.

            ITEM NO. 2. PROPOSAL TO CLARIFY ARTICLES OF INCORPORATION

     At the Annual Meeting of  Shareholders  in 2000,  shareholders  approved an
amendment to the Articles of Incorporation authorizing the election of directors
in classes. Under the amendment, the Corporation's Board of Directors is divided
into  classes of  directors  with one class of directors to be elected each year
commencing in 2001,  with each class of director so elected to hold office for a
term expiring on the second Annual Meeting  following their  election.  The same
procedure is to be provided  each year until such time as the Board is comprised
of nine (9) or more  directors.  At that time,  the Board  will be divided  into
three separate classes of directors,  with Class I directors to be elected for a
one (1) year term, Class II directors to be elected for a two (2) year term, and
Class III directors to be elected for a three (3) year term. As the term of each
class  expires,  that class will be reelected for a three (3) year term. For the
2001 Annual Meeting of Shareholders  the Board of Directors has recommended nine
directors; accordingly, three classes of directors will be elected at the May 9,
2001 Annual Meeting of Shareholders.

     The  Articles of  Incorporation  state that Class III  directors  are to be
elected for a three (3) year term. The Articles  incorrectly state that the term
of Class III  Directors  expires on the  conclusion  of the "second"  succeeding
Annual  Meeting of  Shareholders  following the election of Class III directors.
The Articles  should state that the term of Class III  directors  expires on the
"third"  succeeding  Annual  Meeting of  Shareholders  following the election of
Class III directors.  All other references in the Articles of Incorporation make
it clear  that  Class III  directors  are to serve for a three  year  term.  The
adoption of this  amendment will assure that the Articles of  Incorporation  are
clear about the term of Class III  directors  by  substituting  the word "third"
succeeding  Annual Meeting for the word "second"  succeeding  Annual Meeting.  A
copy  of the  amendment  language  is set  forth  in  Exhibit  1 to  this  Proxy
Statement.

     THE BOARD OF DIRECTORS  UNANIMOUSLY  RECOMMENDS THAT  SHAREHOLDERS  APPROVE
THIS AMENDMENT TO THE ARTICLES OF INCORPORATION.

        ITEM NO. 3. PROPOSAL TO RATIFY APPOINTMENT OF ARTHUR ANDERSEN LLP
                           AS INDEPENDENT ACCOUNTANTS

     Arthur Andersen LLP,  independent public accountants  ("Arthur  Andersen"),
was the  principal  accounting  firm used by the Company  during the fiscal year
ended December 31, 2000. Arthur Andersen has served as the Company's independent
public  accountant  since 1994.  The Board of  Directors  has  appointed  Arthur
Andersen as the principal independent  accounting firm to be used by the Company
during the current fiscal year. A representative  of Arthur Andersen 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.

                       FISCAL YEAR 2000 AUDIT FEE SUMMARY

     During fiscal year 2000, Arthur Andersen provided services in the following
categories to the Company and was paid the following amounts:

     Financial Statement Audit Fees and Quarterly Reviews          $115,000
     All Other Fees                                                $ 83,000

     All Other  Fees  include  amounts  that were paid by the  Company to Arthur
Andersen for certain tax and due  diligence  procedures  performed in connection
with the Company's acquisition of John Fayard Fast Freight, Inc.

                                       -6-

     The Audit  Committee  has  considered  whether the  provisions of non-audit
services by the  Company's  principal  auditor is  compatible  with  maintaining
auditor independence.

     THE  BOARD  OF  DIRECTORS  RECOMMENDS  A VOTE FOR THE  RATIFICATION  OF THE
APPOINTMENT OF ARTHUR ANDERSEN.

                             CORPORATE GOVERNANCE --

     MEETINGS AND COMPENSATION OF THE BOARD OF DIRECTORS AND ITS COMMITTEES

BOARD OF DIRECTORS. The Company's affairs are managed by the Board of Directors.
During the year ended  December 31, 2000,  the Board of Directors of the Company
met on four occasions and once through  resolutions  and actions taken without a
meeting. Each of the directors 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.

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.  Independent  Directors appointed to
the Board of Directors also receive an automatic grant of a non-qualified  stock
option  ("NSO") for a number of shares of Common Stock to be  designated  by the
Board of not fewer than 2,500 nor more than 5,000 shares.  The exercise price of
a NSO is 85% of the fair market value of the  Company's  stock as of the date of
grant.  The option is forfeitable if a director  resigns one year after election
as a director.  The Board of Directors has granted each of Donald A. Bliss, G.D.
Madden, and Mark Scudder,  an NSO for 2,500 shares of the Company's Common Stock
at original  exercise prices of $13.18,  and $20.19,  and $11.75,  respectively.
Members of the Board of Directors  also have the option to accept  shares of the
Company's  Common Stock in lieu of  director's  fees. If this option is elected,
the  Company  issues  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.

     Mr.  Randy  Knight,  who is a director  of the  Company,  also  serves as a
consultant  to the Company  and  receives  $50,000  per year for his  consulting
services. The consulting agreement with Mr. Knight is terminable at the election
of either party.

COMMITTEES OF THE BOARD OF DIRECTORS

     The  Board  of  Directors  has  established  three  committees,  which  are
authorized  to act on  behalf  of the  Board in their  respective  spheres:  the
Executive  Committee,  the Audit Committee and the Compensation  Committee.  The
responsibilities of each Committee are described below.

                                       -7-

                               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  Knight,  Gary Knight,  Don Bliss,  and Mark  Scudder.  The
Executive Committee did not meet in 2000.

                   AUDIT COMMITTEE AND AUDIT COMMITTEE REPORT

     The Audit  Committee  for 2000 was  composed  of  Donald A.  Bliss and G.D.
Madden. Mr. Bliss served as Chairman of the Audit Committee. The Audit Committee
met four times during 2000. The  responsibilities of the Audit Committee are set
forth in the Audit Committee Report,  which appears below. All of the members of
the Audit  Committee are independent  directors,  as defined in the NASDAQ Stock
Market's  Listing  Rule 4200.  Since 1994,  the Audit  Committee,  has  operated
pursuant  to a written  charter  detailing  its  duties.  The Audit  Committee's
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 the  Company's
audited financial  statements be included in the Company's Annual Report on Form
10-K, and certain other  matters,  including the  independence  of the Company's
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 THE COMPANY UNDER THE  SECURITIES ACT OF 1933
ON 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 THE COMPANY INCORPORATES 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, 2000,  Donald Bliss and G.D. Madden
comprised the Audit Committee. Donald Bliss acted as the Chairman.

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

                                       -8-

     The Board of  Directors  has adopted a written  charter  setting  forth the
Audit  Committee's  functions.  A copy of the Audit  Committee's  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  auditing  standards  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 has primary  responsibility  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 operation 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, 2000, the Audit Committee:

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

     (2) Discussed  with Arthur  Andersen 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) Reviewed and discussed the written  disclosures and the letter from the
Company's   independent   auditors  the  matters   relating  to  the   auditor's
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, 2000, filed with the Securities and
Exchange Commission.


Donald Bliss, Chairman                                          February 7, 2001

                             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 full Board of Directors. The Compensation
Committee  also reviews and approves stock options  granted by the Company.  The
Audit  Committee  met  formally  once in 2000 to issue its  Report on  Executive
Compensation.  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.

                                OTHER COMMITTEES

     The Company  does not  maintain a standing  nominating  committee  or other
committee performing a similar function.

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

     Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
directors  and  executive  officers,  and  persons  who own  more  than 10% of a
registered class of the Company's 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 the Company 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,  the
Company  believes  that during the 2000 fiscal  year,  all Section  16(a) filing
requirements  applicable to its directors,  executive  officers and greater than
10% beneficial owners were complied with.

LONG TERM INCENTIVE PLAN

     Other than the  Company's  Stock  Option Plan in which the Named  Executive
Officers, other than Mr. Timothy M. Kohl and Dr. Bruce Beck, do not participate,
the Company does not have a long-term  incentive plan or a defined benefit plan,
and the Company has not issued any stock appreciation rights.

EMPLOYMENT AGREEMENTS

     The Company currently does not have any employment contracts,  severance or
change-in-control agreements with any of its Named Executive Officers.

     Upon Randy  Knight's  retirement as Chairman in 1999,  the Company  entered
into a Consulting  Agreement  with Mr.  Randy  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

     The Company  adopted in 1994 and  currently  maintains a stock  option plan
(the "Plan" or the "Stock Option Plan") to enable directors,  executive officers
and certain key and critical line  employees of the Company,  including  drivers
and other  employees,  to participate in the ownership of the Company.  The Plan
was amended and restated  during 1998 to  authorize  the grant of options for an
additional  525,000  shares of  Common  Stock  under  the  Plan,  for a total of
1,500,000  shares of Common Stock,  after giving  effect to the  Company's  1998
stock dividend. The Plan is designed to attract and retain directors,  executive
officers,  key  employees  and critical  line  employees of the Company,  and to
provide long-term incentives to those persons. In authorizing stock grants under
the Plan,  the  Compensation  Committee  has  sought to align the  interests  of
employees with the Company's shareholders and has sought to make stock grants to
those key employees and operating  personnel  whose  performance is important to
the Company's success.  As of December 31, 2000, the Company had granted options
to employers  and  directors to purchase  1,202,073  shares of its Common Stock;
297,927  Shares of Common  Stock were  reserved for the issuance of future stock
options and grants.

401(K) PLAN

     The Company  also  sponsors 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 the Company  contribute a portion of his  compensation  to the 401(k) Plan.
The Company makes a discretionary matching contribution. For 2000, the Company's
contribution was $625 per participant. The 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 Plan also allows its  participants  to direct the trustee to
purchase shares of the Company's stock on the open market.  Senior executives of
the Company and certain key employees are not permitted to  participate  in this
aspect of the Plan.

                                      -13-

     Amounts  contributed  by the Company for a participant  will vest over five
years and will be held in trust until  distributed  pursuant to the terms of the
401(k) Plan. An employee of the Company 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 will not be permitted
before age 59-1/2, except in the event of death,  disability,  certain financial
hardships or separation from service.

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 THE COMPANY UNDER THE  SECURITIES ACT OF 1933
OR THE SECURITIES  EXCHANGE ACT OF 1934,  NOTWITHSTANDING  ANY GENERAL STATEMENT
CONTAINED IN ANY SUCH FILING  INCORPORATING  THIS PROXY  STATEMENT BY REFERENCE,
EXCEPT TO THE EXTENT THE COMPANY  INCORPORATES SUCH 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 executive officers
of the Company and makes  recommendations  on such  matters to the full Board of
Directors.  The  Compensation  Committee of the Board of Directors  for 2000 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 the Company 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 the Company's 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 M. Kohl, Chief Financial  Officer and

                                      -14-

Secretary,  and Dr.  Bruce Beck,  Vice  President,  each of whom 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 2000 and  salary
compensation  for  2000-2001,  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 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.

                             COMPENSATION COMMITTEE

                             Mark Scudder, Chairman

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

COMPANY'S PURCHASE AND LEASE OF PROPERTIES

     The Company's  headquarters  and principal  place of business is located at
5601 West Buckeye Road, Phoenix, Arizona, on approximately 43 acres. The Company
owns approximately 35 acres and, as of December 31, 2000, leased approximately 8
acres from Randy Knight,  a director and principal  shareholder  of the Company.
The  property  leased by the Company  from Randy  Knight  includes  terminal and
operating  facilities.  Total payments of approximately $81,000 were made by the
Company to, or on behalf of,  Total  Warehousing  and Randy  Knight for the year
ended  December  31,  2000.  Randy  Knight  owns a 50 percent  interest in Total
Warehousing; the balance is owned by an unaffiliated party.

     The lease between the Company and Randy Knight had an original term at five
(5) years, with two five year renewal options. The original base rent was $4,828
per month and has increased  periodically through automatic rent escalators.  In
March 1999,  the Company  exercised its option to extend the lease term for five
years.  The current  lease term will expire April 30, 2004.  The Company has one
more  option to extend the lease  term for an  additional  five (5)  years.  The
current monthly based 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  the  Company to pay its 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.  The Company has granted  Randy Knight
access and utility easements over its owned and leased properties.  The purchase
and  lease   agreements   between   the  Company   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.

     The Company and Total  Warehousing  from time to time  provide  services to
each other.  Total  Warehousing  provided  general  warehousing  services to the
Company  and was paid  $33,000 by the Company  for the year ended  December  31,
2000.

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

     The Company paid  approximately  $90,000 during 2000 for certain of its key
employees'  life  insurance  premiums.  The total  premiums paid are included in
other assets in the  consolidated  balance sheet attached to Form 10-K. The life
insurance  policies provide for cash  distributions to the  beneficiaries of the
policyholders upon death of the key employee. The Company is entitled to receive
the  total  premiums  paid  out on the  policies  at  distribution  prior to any
beneficiary distributions.

CONCENTREK INVESTMENT

     The Company periodically examines investment opportunities in areas related
to the truckload carrier business.  The Company's  investment strategy is to add
to  shareholder  value by investing  in industry  related  businesses  that will
assist the Company in strengthening  its overall position in the  transportation
industry,  minimize  the  Company's  exposure to  start-up  risk and provide the
Company with an opportunity to realize a substantial  return on its  investment.
In  April  1999,  the  Company  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. The Company's investment in
Concentrek  was approved by a majority of the Company's  Independent  Directors.
The Company holds  non-voting  Class A Preferred  Stock in  Concentrek  which is
preferred  in the event of  liquidation,  dissolution,  sale or merger  and with

                                      -17-

respect to dividends  over all other classes of stock,  including  stock held by
members of the Knight family.  The Company has preferential  rights in the event
Concentrek  issues  additional  shares and limited voting rights with respect to
merger,  consolidation,  sale of substantially all of Concentrek's  assets,  and
certain other major corporate events.  The Company,  through a limited liability
company,  has agreed to lend up to a maximum of $935,000 to Concentrek  pursuant
to a  promissory  note to fund  start-up  costs.  The note is  convertible  into
Concentrek's  Class A Preferred  Stock and is secured by a lien on  Concentrek's
assets.  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  may lend up to a
maximum of $4,565,000 to Concentrek  pursuant to a promissory  note  convertible
into Concentrek Class B Preferred Stock to fund Concentrek's start-up costs. The
loans to  Concentrek  made by the Company and the Knights are on a parity  basis
with regard to security.  The Company's  investment has been structured to limit
its exposure to Concentrek start-up losses and business risk.

KNIGHT FLIGHT

     In November  2000,  the Company  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  $8,942,700.  The  Company  invested
$1,717,700  in Knight Flight in order to assure access to charter air travel for
the Company's  employees.  The Company has a priority use right for the aircraft
and is 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 to  contribute  any  capital  required  to meet any cash  short  falls.  The
Company's  acquisition  of its  interest  in Knight  Flight  was  approved  by a
disinterested majority of the Company's board of directors. The Company believes
that its  interest in Knight  Flight will allow it access to needed  charter air
services for Company  business at prices equal to or less than is available from
unrelated charter companies.

TRANSACTIONS WITH AFFILIATES

     The Company has adopted a policy that transactions with affiliated  persons
or entities  will be on terms no less  favorable  to the Company 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 the  Company's  Independent
Directors.

CERTAIN BUSINESS RELATIONSHIPS

     During 2000, the Company retained Scudder Law Firm to perform certain legal
services on its behalf. The Company paid Scudder Law Firm approximately $116,000
for services  during 2000.  The amounts paid to Scudder Law Firm  exceeded 5% of
that Firm's revenue in 2000.  Mark Scudder,  a member of the Company's  Board of
Directors,  is a member of Scudder  Law Firm and  performed  legal  services  on
behalf of the Company. (The Company used the services of Scudder Law Firm during
2000, and intends to continue the use of Scudder Law Firm during 2001.)

                                    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.

     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") in order to comply
with the  applicable  provisions  of the  NASDAQ  Release  and the SEC  Release.
Accordingly,  the Charter is hereby  amended and restated,  in its entirety,  as
follows,  effective  as of May  10,  2000,  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  and to  ensure  the  existence  of  appropriate  internal  financial
controls, and the independence of the independent public accounting firm engaged
to audit the Company's financial  statements (the "external  auditors"),  and 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(e)(3) of Schedule 14(A) and related Commission regulations.

     2. QUALIFICATIONS OF AUDIT COMMITTEE.  The Audit Committee shall consist of
not less than two (and not later than June 14, 2001,  three  directors) nor more
than five directors,  each of whom qualifies as an "independent  director" under
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  fundamental  financial  statements,  including the Company's balance
sheet,  income statement,  and cash flow statement.  Additionally,  at least one
member  of the  Audit  Committee  shall,  in the  judgment  of the  Board,  have
experience in finance or accounting,  requisite  professional  certification  in
accounting,  or any other  comparable  experience  or  background  in evaluating
financial  statements,  which may include past  experience as a chief  executive
officer,  chief  financial  officer  or  other  senior  officer  with  financial
oversight responsibilities.

     3.  DUTIES  OF THE AUDIT  COMMITTEE.  Subject  to the  second  sentence  of
Paragraph 10, below,  the Audit  Committee will perform the following  duties in
the manner and priority the Audit Committee determines, in its discretion, to be
appropriate under the circumstances:

with management and with the Company's external auditors prior to the release of

Commission as part of the Company's report on Form 10-K;

          (c) Review and discuss the Company's audited financial statements with

Company to assure that such services do not  compromise  the external  auditors'
independence;

dialogue  with the  external  auditors,  with  respect to any  relationships  or

the external  auditors and take, or recommend  that the Board take,  appropriate
action to ensure the independence of the external auditors;

          (g)  Review  annually  the  scope  of  the  external  auditors'  work,

quarterly interim financial statements;

          (i) Review with  management  and the Company's  external  auditors any
significant  financial  reporting  issues or judgments  called for in connection

adequacy  and  appropriateness  of  any  reserves,   policies  relating  to  the
recognition  of  revenue,  the  quality  and  appropriateness  of the  Company's

the Company's  external  auditors,  the Audit Committee will, in accordance with
SAS-61,  communicate with the external auditors with respect to (1) methods used
to  account  for  significant  or  unusual  transactions;   (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

of accounting principles,  the basis for management's accounting estimates,  and
the disclosures in the Company's financial statements);

external  auditors and review their fees and the proposed  scope and plan of the
annual audit;

          (o) Review the external  auditors'  management letter and consider any
comments  made by the  external  auditors  with respect to  improvements  in the
internal  accounting  controls of the Company,  consider any  corrective  action
recommended by the external auditors,  and review any corrective action taken by
management;

                                      -3-

          (p) Review and devote  attention to any areas in which  management and
the  Company's  external  auditors  disagree and  determine the reasons for such

          (q)  Review  the   performance  of  the  external   auditors  and,  if

          (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; and

          (u)  Periodically  review  the  adequacy  of  this  Charter  and  make
recommendations to the Board with respect to any changes in the Charter.

     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. EMPLOYEE ACCESS TO AUDIT  COMMITTEE.  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.

                                      -4-

     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. If any claim is asserted against
the Audit  Committee,  any of its members or the Company by  shareholder  or any
other  person,  nothing in this Charter  shall be construed to limit or restrict
any defense  available to the Audit  Committee,  any of its  members,  or to the
Company.
