Traffic Safety Facts: Results of the 2007 National Roadside Survey of Alcohol and Drug Use by Drivers. Research Note

摘要

Over the last four decades, the National Highway Traffic Safety Administration (NHTSA) and/or the Insurance Institute for Highway Safety have conducted four national surveys to estimate the prevalence of drinking and driving in the U.S. (Wolfe, 1974; Lund and Wolfe, 1991; Voas, et al, 1998). These surveys utilized a stratified random sample of weekend nighttime drivers in the contiguous 48 States. The first National Roadside Survey (NRS) was conducted in 1973, followed by national surveys of alcohol use by drivers in 1986, 1996, and 2007. The 2007 NRS included, for the first time, measures to estimate the use of other potentially impairing drugs by drivers. Prior roadside surveys had collected breath samples to determine blood alcohol concentration (BAC).
