ANNOUNCES RESULTS FOR THE SECOND QUARTER

ENDED JUNE 30, 2006

Tontitown, Arkansas, July 26, 2006......P.A.M. Transportation Services, Inc. (NASDAQ: PTSI) today reported net income of $5,241,387 or diluted and basic earnings per share of $.51 for the quarter ended June 30, 2006, and $10,424,746 or diluted and basic earnings per share of $1.01 for the six month period then ended. These results compare to net income of $3,679,592 or diluted and basic earnings per share of $.33, and $6,582,979 or diluted and basic earnings per share of $.59, respectively, for the three and six months ended June 30, 2005.

Operating revenues excluding fuel surcharges were $89,691,702 for the second quarter of 2006, a 7.6% increase compared to $83,321,440 for the second quarter of 2005. Operating revenues excluding fuel surcharges were $180,541,154 for the six months ended June 30, 2006, a 10.5% increase compared to $163,429,915 for the six months ended June 30, 2005.

Robert W. Weaver, President of the Company, commented, “We are very pleased with results for our second quarter. Good utilization and steady demand combined with favorable pricing produced record results for the Company in both earnings per share and net income. Year over year net income improved 42.4% and earnings per share improved 54.5% for the second quarter ended June 30, 2006 as compared to the second quarter ended June 30, 2005.

Revenue per total mile, before fuel surcharge, increased 9.6% to $1.34 from $1.23 for the quarters ended June 30, 2006 and 2005 respectively. The slight decrease in this rate from $1.37 per total mile, before fuel surcharge, for the first quarter of 2006 represents a transition of several lanes from temporary spot rates which included fuel surcharge to longer term contractual rates that break the regular and fuel surcharge rate into separate components.

Total miles were down slightly as a result of one less workday in the second quarter of 2006 compared to 2005 and a decrease in the average number of owner operators contracted with the Company from 70 to 45 for the quarter ended June 30, 2005 and 2006 respectively. However, average total tractors increased by 32 tractors from the first quarter to the second quarter of 2006. The majority of these tractor additions occurred late in the quarter, and as a result the impact of this additional equipment should be more apparent in the third quarter of 2006.

Customer demand remained strong throughout most of our customer base, including the automotive market, which comprised approximately 52% of our total revenue before fuel surcharge for the quarter ended June 30, 2006. While automotive freight for the second quarter 2006 is up slightly when compared to the second quarter of 2005, it is down from 54% reported for the first quarter of 2006.

While we are pleased with our results, we remain keenly aware of the forces at work that have created a sustained volatility in petroleum pricing that has directly affected our fuel cost. This fuel volatility coupled with the cost of hiring, compensating and retaining safe, qualified drivers are currently our most challenging concerns pertaining to operating costs. We will continue to strive to contain the components of these expenses which are in our control in order to mitigate their affect on future earnings and continue 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.
