                      P.A.M. TRANSPORTATION SERVICES, INC.
                    ANNOUNCES RESULTS FOR THE SECOND QUARTER
                             ENDED JUNE 30, 2004

Tontitown, Arkansas, July 26, 2004..........P.A.M. Transportation Services, Inc.
(NASDAQ:  PTSI)  today  reported  net  income of $3,647,123 or diluted and basic
earnings  per  share of $.32 for the quarter ended June 30, 2004, and $5,677,941
or  diluted  and  basic earnings per share of $.50 for the six month period then
ended.  These  results  compare to net income of $4,046,569 or diluted and basic
earnings  per  share  of  $.36, and $6,864,138 or diluted and basic earnings per
share  of  $.61, respectively, for the three and six months ended June 30, 2003.

Operating  revenues of $79,070,723 were reported for the second quarter of 2004,
a  5.5%  increase  compared  to  $74,956,404  for  the  second  quarter of 2003.
Operating  revenues for the six months ended June 30, 2004 were $156,744,158, an
8.0%  increase  compared to $145,095,314 for the six months ended June 30, 2003.

Robert  W. Weaver, President of the Company, commented, "Comparisons made of our
second  quarter 2004 results to the results of the second quarter of 2003 do not
adequately  reflect  the  true improvements made by the company in the past four
quarters.  A  more  accurate  picture  of  the improvements in our operations is
apparent  by  comparing  successive  quarters.  Increases  in freight rates have
erased the decrease that was experienced in rate per mile during the second half
of  2003 and surpassed rate levels that were in place prior to that period. Cost
containment  measures  and  programs  put  in  place in workers compensation and
maintenance  reflect  improvement  as  well.  As  we  have  stated  previously,
improvements  in  operations continues to be a work in process evidenced by more
improvement in each month of the quarter ending June 30, 2004."

P.A.M. Transportation Services, Inc. will be holding a live conference call with
certain  financial  analysts  to  discuss  the  earnings release, the results of
operations,  and  other  matters  on  Tuesday,  July  27, 2004 at 10:00 a.m. CDT
