                      P.A.M. TRANSPORTATION SERVICES, INC.
                    ANNOUNCES RESULTS FOR THE SECOND QUARTER
                             ENDED JUNE 30, 2005

Tontitown, Arkansas, July 28, 2005..........P.A.M. Transportation Services, Inc.
(NASDAQ:  PTSI)  today  reported  net  income of $3,679,592 or diluted and basic
earnings  per  share of $.33 for the quarter ended June 30, 2005, and $6,582,979
or  diluted  and  basic earnings per share of $.59 for the six month period then
ended.  These  results  compare to net income of $3,647,123 or diluted and basic
earnings  per  share  of  $.32, and $5,677,941 or diluted and basic earnings per
share  of  $.50, respectively, for the three and six months ended June 30, 2004.

Operating  revenues  excluding  fuel  surcharges were $83,321,440 for the second
quarter  of 2005, a 5.4% increase compared to $79,070,723 for the second quarter
of  2004. Operating revenues excluding fuel surcharges were $163,429,915 for the
six months ended June 30, 2005, a 4.3% increase compared to $156,744,158 for the
six months ended June 30, 2004.

Robert  W. Weaver, President of the Company, commented, "Results from our second
quarter  of 2005 showed modest improvement in earnings as compared to the second
quarter  of 2004. We achieved these results despite significant downtime at many
of  our  automotive  customers,  a  substantial driver pay increase, and overall
softness in the general truckload sector as reported by some of our competitors.
Revenue,  before  fuel  surcharge,  increased  5.4%. We feel our results for the
quarter  reflect  the  positive steps implemented to diversify our customer base
allowing  us  the  flexibility  to respond to varying demand from the automobile
industry. Projected downtime for the remainder of the year is currently expected
to  be  minimal.  Revenue  per  mile,  before  fuel  surcharges, showed a strong
increase  of 10% from $1.11 in the second quarter of 2004 to $1.23 in the second
quarter  of 2005. Although collections from fuel surcharges increased from 4.06%
of  revenues,  before fuel surcharges, in the second quarter of 2004 to 9.25% in
the  second quarter of 2005, the increased cost of fuel, net of fuel surcharges,
had the effect of reducing earnings per share by $.09 for the quarter."

P.A.M. Transportation Services, Inc. will be holding a live conference call with
