Exhibit 23.1



                         Independent Auditors' Consent


The Board of Directors
Knight Transportation, Inc.:

We consent to the incorporation by reference in the registration statements Nos.
333-72377  and  333-105718  on Form S-8 of Knight  Transportation,  Inc.  of our
report dated January 21, 2004 with respect to the consolidated balance sheets of
Knight  Transportation,  Inc. and subsidiaries as of December 31, 2003 and 2002,
and  the  related  consolidated  statements  of  income,  comprehensive  income,
shareholders'  equity,  and cash flows for the years then ended, and the related
financial  statement  schedule  for the years ended  December 31, 2003 and 2002,
which report  appears in the December  31, 2003,  annual  report on Form 10-K of
Knight Transportation, Inc.

Our report  dated  January  21,  2004  states  that the  consolidated  financial
statements   and   consolidated   financial   statement   schedule   of   Knight
Transportation,  Inc. and  subsidiaries as of December 31, 2001 and for the year
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  in Note 1 are
appropriate.  However,  we were not  engaged  to  audit,  review,  or apply  any
procedures   to  the  2001   consolidated   financial   statements   of   Knight
Transportation,   Inc.  and  subsidiaries   other  than  with  respect  to  such
disclosures.
