abstract="This paper discusses the role of roadside surveys in defining the drug and driving problem. Past roadside surveys conducted in the United States are briefly reviewed, and research constraints and methodological issues are identified. Of particular concern are subject cooperation in studies that require the chemical analysis of blood specimens and the use of appropriate incentives to enhance cooperation. Alternative methods required for the study of drugs other than alcohol alone are identified and possible approaches to the design and conduct of roadside surveys in the United States are outlined.<p />",
