ANNOUNCES RESULTS FOR THE FIRST QUARTER

ENDED MARCH 31, 2007

Tontitown, Arkansas, May 2, 2007......P.A.M. Transportation Services, Inc. (NASDAQ: PTSI) today reported net income of $1,264,931 or diluted and basic earnings per share of $.12 for the quarter ended March 31, 2007. These results compare to net income of $5,183,360 or diluted and basic earnings per share of $.50 for the quarter ended March 31, 2006. Operating revenues excluding fuel surcharges were $87,543,603 for the first quarter of 2007, a 3.6% decrease compared to $90,849,451 for the first quarter of 2006.

Robert W. Weaver, President of the Company, commented, “Several factors contributed to the reduction of net income for the first quarter of 2007 when compared to the first quarter of 2006. Predominant among these factors was the softening of the freight market in the first quarter of 2007. This decline in demand resulted in very aggressive competition for available freight and generally resulted in a shift to a market more favorable to shippers. The softer freight demand resulted in a decrease in our equipment utilization and a $.08 decrease in our revenue per total mile, before fuel surcharges, for the quarter ended March 31, 2007 compared to March 31, 2006.

Other detriments to first quarter profit included increases in equipment maintenance costs and, to a lesser degree, fuel expense. Severe weather experienced in many of the states which we operate in most heavily resulted in year over year increases in equipment maintenance costs and decreased fuel efficiency. In addition, the cost of fuel increased sharply in March, outpacing offsetting increases in fuel surcharges recovered from customers.

Depreciation expense increased approximately $980,000 for the first quarter of 2007 compared to the same period in 2006. This increase resulted from a 279 truck year to year growth in the average number of company owned trucks from 1,739 in the first quarter of 2006 to 2,018 in the first quarter of 2007.

While these increases in operating costs were contributory to reduced year over year first quarter net income, our number one challenge remains achieving improvements in freight rates and equipment utilization in the current freight market. If rate and utilization levels achieved in the first quarter of 2006 had remained level in the first quarter of 2007, the Company would have seen little shortfall from expectations.”

___________________________________________________________

* 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.
