ANNOUNCES RESULTS FOR THE FIRST QUARTER

ENDED MARCH 31, 2006

Tontitown, Arkansas, April 26, 2006......P.A.M. Transportation Services, Inc. (NASDAQ: PTSI) today reported a 78.5% increase in net income to $5,183,360 and a 92.3% increase in diluted and basic earnings per share to $.50 for the quarter ended March 31, 2006 as compared to net income of $2,903,387 or diluted and basic earnings per share of $.26 for the quarter ended March 31, 2005. Operating revenues excluding fuel surcharges were $90,849,451 for the first quarter of 2006, a 13.4% increase compared to $80,108,475 for the first quarter of 2005.

Robert W. Weaver, President of the Company, commented, “We are pleased to announce the results of operations for the first quarter of 2006. We have been working diligently on the key elements of our operating plan. We were, and continue to be, confident that we are applying our efforts in the correct areas to achieve success and we feel the results speak for themselves. Our consolidated operating ratio for the first quarter of 2006 improved to 90.0% for the first quarter of 2006 from 93.6% for the first quarter of 2005, and our operating ratio for our truckload business improved to 89.2% from 93.3% for the same periods.

We experienced strong demand for our services during the quarter ended March 31, 2006, which helped to drive a 13.4% increase in revenue, before fuel surcharge. Revenue per loaded mile, before fuel surcharge, increased 12.7% to $1.45 from $1.28 for the quarters ended March 31, 2006 and 2005, respectively. In addition, revenue per tractor per week, before fuel surcharge, for truckload business increased 13.9% to $3,480 per week during the first quarter of 2006 from $3,055 per week during the first quarter of 2005. Demand was strong throughout our customer base, including our automotive business, which remains an integral part of our customer mix and contributes to our overall operating efficiencies. Automotive freight constituted approximately 54% of our total revenue, before fuel surcharge, a slight gain when compared to the first quarter of 2005. This gain was largely driven by improved pricing in this segment, as opposed to an increase in the actual shipments handled, which actually decreased.

We are encouraged by the results achieved and remain focused on improving the fundamentals of our business. By closely monitoring the evolution of our industry in regard to professional drivers, petroleum prices, and the changing needs of our customers we will strive to add value for our shareholders.”

___________________________________________________________

* Operating ratio has been calculated based upon total operating expenses, net of fuel surcharge, as a percentage of revenue, before fuel surcharge. We used revenue, before fuel surcharge, and operating expenses, net of fuel surcharge, because we believe that eliminating this sometimes volatile source of revenue affords a more consistent basis for comparing our results of operations from period to period.
