EXHIBIT 23.2

NOTICE REGARDING CONSENT OF ARTHUR ANDERSEN LLP

     Section 11(a) of the  Securities Act of 1933 provides that in case any part
of a  registration  statement,  when such part became  effective,  contained  an
untrue  statement  of a material  fact,  or  omitted  to state a  material  fact
required to be stated  therein or necessary to make the  statements  therein not
misleading,  any person  acquiring  a  security  pursuant  to such  registration
statement  (unless it is proved that at the time of such acquisition such person
knew of such untruth or omission) may sue,  among others,  an accountant who has
with his consent  been named as having  certified  any part of the  registration
statement, or as having prepared any report which is used in connection with the
registration statement.

     On April 29, 2002, we terminated Arthur Andersen LLP ("Arthur Andersen") as
our  independent  auditors.  After  reasonable  efforts,  we have been unable to
obtain Arthur  Andersen's  written consent to the  incorporation by reference of
Arthur  Andersen's  audit report with respect to our financial  statements as of
December  31, 2001 and for the years ended  December  31, 2001 and  December 31,
2000 into our  registration  statements  on Form S-8 No.  333-72377  relating to
common stock of Knight Transportation, Inc. ("Knight") issuable upon exercise of
options  under the 1998  Stock  Option  Plan.  We were  unable to obtain  Arthur
Andersen's  written  consent  because Arthur Andersen is no longer in the public
accounting business and does not issue written consents.

     Under  these  circumstances,  Rule 437a  under the  Securities  Act of 1933
permits Knight to file this Form 10-K,  which is  incorporated by reference into
the above listed registration  statement,  without a written consent from Arthur
Andersen.  However,  as a result,  Arthur  Andersen  will not have any liability
under  Section  11(a)  of the  Securities  Act for any  untrue  statements  of a
material fact contained in the financial  statements  audited by Arthur Andersen
or any omissions of a material fact required to be stated therein.  Accordingly,
you would be unable to assert a claim  against  Arthur  Andersen  under  Section
11(a) of the Securities Act.
