2007 National Roadside Survey of Alcohol and Drug Use by Drivers: Drug Results

This report presents the first national prevalence estimates for drug-involved driving derived from the recently completed 2007 National Roadside Survey (NRS). The NRS is a national field survey of alcohol- and drug-involved driving conducted primarily among nighttime weekend drivers, but also daytime Friday drivers. The survey involved randomly stopping drivers at 300 locations across the continental United States; sites were selected through a stratified random sampling procedure. This included data that we collected during a two-hour Friday daytime session at 60 locations and during four 2-hour nighttime periods (10 p.m. to midnight and 1 a.m. to 3 a.m. on both Friday and Saturday) at 240 locations. Both self-report and biological measures were taken. Biological measures included breath alcohol measurements on 9,413 respondents, oral fluid from 7,719 respondents, and blood samples from 3,276 respondents. Oral fluid and blood samples were subjected to laboratory screening and LC/MS-MS and GC/MS confirmation for 75 drugs and metabolites, including illegal, prescription, and over-the-counter drugs. These data were analyzed to develop the first national prevalence estimate of alcohol- and drug-involved driving. Two prior reports on the 2007 NRS described: (1) the sampling plan and data collection methodology, summarizing the response patterns to the various stages of the multi-part survey; and (2) the prevalence estimates for alcohol-involved driving derived from the study, and comparing them with the three previous National Roadside Surveys (NRS).
