National Roadside Survey

A major component of addressing the impaired driving crash risk question is determining the incidence of drivers on the road with positive blood alcohol concentrations (BACs) and/or who have measurable amounts of drugs in their system. Five "national roadside surveys" were conducted on the incidence of impaired drivers on the road in 1973, 1986, 1996, 2007, and 2013-2014. This research project will provide current data on the incidence of alcohol-positive, and drug-positive, drivers through a national roadside survey planned for 2025. The methodology will largely follow from the most recent surveys, but it will strive for more representative samples of drivers. In addition, NHTSA is concerned about increasing numbers of fatalities among pedestrians and other vulnerable road users. Understanding the scope of alcohol and drug use among these road users will inform countermeasure development. Because of this need, NHTSA will also obtain data from road users other than drivers, such as pedestrians, bicyclists, and electric scooter riders, at the data collection locations. It will also pilot test a methodology for conducting a roadside survey without drivers, focused on these other road users as participants. This study also allows for an optional task for additional testing attitudes and awareness of traffic safety issues, human subjects testing and/or validation studies with newly developed behavioral test batteries or technology.
