The National Highway Traffic Safety Administration recently submitted the first of two reports, prepared in response to a congressional mandate to study the alcohol concentration at which a driver should be considered under the influence. The report was reviewed and approved by various modal administrations and by the Office of the Secretary of Transportation before being submitted by the Secretary. This article covers a portion of the congressional report, specifically scientific literature on the influence of alcohol concentration on driver performance and crashes. The conclusions are the same as in the congressional report. A small amount of editing was done to the text selected from the report to smooth transitions and to clarify points raised by reviewers.
