16. Abstract

This study developed and tested procedures to enhance roadside survey procedures to include collecting and analyzing oral fluid and blood samples from the nighttime weekend driving population. Roadside surveys involve collecting information from a random sample of drivers. In the past, they have been used to measure the extent of alcohol use in the nighttime driving population in order to establish regular measures of that activity, which is a measure of progress in reducing impaired driving. This study developed and tested techniques to extend the scope of that measurement to drugs other than alcohol. Breath and oral fluid samples were successfully collected from over 600 drivers at 6 locations across the United States. Blood samples were obtained from approximately half of those subjects. Laboratory analyses for alcohol and other drugs were conducted on the oral fluid and blood samples. Procedures and results are described in this report. The findings indicate that this form of expanded roadside survey is practicable in the United States. The intent of this Pilot Test was to develop and test procedures that would be used in the next full-scale national roadside survey. It was not designed to yield a nationally-representative sample of the nighttime weekend driving population; thus the results are not representative of the United States as a whole.
