This press release contains forward-looking statements and information that are based on our current beliefs and expectations and assumptions we have made based upon information currently available. Forward-looking statements include statements relating to our plans, strategies, objectives, expectations, intentions and adequacy of resources, and may be identified by words such as "will," "could," "should," "may," "believe," "expect," "intend," "plan," "schedule," "estimate," "project" and similar expressions. These statements are based on current expectations and are subject to uncertainty and change. Although we believe that the expectations reflected in such forward-looking statements are reasonable, we cannot assure you that such expectations will be realized. If one or more of the risks or uncertainties underlying such expectations materialize, or if underlying assumptions prove incorrect, actual results may vary materially from those expected. Among the key factors that are not within our control and that have a direct bearing on operating results are increases in fuel prices, adverse weather conditions, increased regulatory burdens and the impact of increased rate competition. Our results have also been, and will continue to be, significantly affected by fluctuations in general economic conditions, as our tractor utilization is directly related to business levels of customers in a variety of industries. In addition, shortages of qualified drivers and intense or increased competition for drivers have adversely impacted our operating results and our ability to grow and will continue to do so. Results for any specific period could also be affected by various unforeseen events, such as unusual levels of equipment failure or vehicle accident claims, as illustrated by our adverse experience with self-insured claims in the fourth quarter of 2005. Additional risks associated with our operations are discussed in our SEC filings, including our annual report on Form 10-K and our quarterly reports on Form 10-Q.

All forward-looking statements attributable to us, or persons acting on our behalf, are expressly qualified in their entirety by this cautionary statement.

We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise. In light of these risks and uncertainties, the forward-looking events and circumstances discussed in this press release might not occur.

References to the "Company," "we," "us," "our" and words of similar import refer to USA Truck, Inc. and its subsidiary.
