Exhibit 23.1

                          INDEPENDENT AUDITORS' CONSENT

The Board of Directors
Knight Transportation, Inc.:

We consent to the incorporation by reference in the registration  statement (No.
333-72377) on Form S-8 of Knight  Transportation,  Inc. and  subsidiaries of our
report dated  January 22, 2003,  except as to paragraph 1 of Note 3, which is as
of February 13, 2003, with respect to the  consolidated  balance sheet of Knight
Transportation,  Inc. and  subsidiaries as of December 31, 2002, and the related
consolidated statements of income,  comprehensive income,  shareholders' equity,
and cash flows for the year then  ended,  and the  related  financial  statement
schedule,  which report appears in the December 31, 2002,  annual report on Form
10-K of Knight Transportation, Inc. and subsidiaries.

Our report dated January 22, 2003,  except as to paragraph 1 of Note 3, which is
as of February 13, 2003, states that the consolidated  financial  statements and
consolidated  financial  statement schedule of Knight  Transportation,  Inc. and
subsidiaries  as of December 31, 2001, and for each of the years in the two-year
period then ended were  audited by other  auditors  who have ceased  operations.
Those auditors expressed an unqualified opinion on those consolidated  financial
statements  in their report dated  January 16, 2002. As described in Note 1, the
consolidated  financial statements have been revised to include the transitional
disclosures  required by Statement of Financial  Accounting  Standards  No. 142,
GOODWILL  AND OTHER  INTANGIBLE  ASSETS,  which was adopted by the Company as of
January 1, 2002. In our opinion, the disclosures for 2001 and 2000 in Note 1 are
appropriate.  However,  we were not  engaged  to  audit,  review,  or apply  any
procedures  to the 2001 and 2000  consolidated  financial  statements  of Knight
Transportation,   Inc.  and  subsidiaries   other  than  with  respect  to  such
disclosures.
