Notes: Source of data: 2007 National Roadside Survey and the 2006–2007 U.S. Fatality Analysis Reporting System. 95% confidence intervals of relative risk are in brackets. Relative risk corresponds to the relative risk at the midpoint of the BAC interval (i.e., .015, .035, .065, .090, .125, and .220). BAC = blood alcohol concentration; FSV = fatalities in single-vehicle crashes; IAll = involvement in all fatal crashes (involvement denotes drivers who were involved in a fatal vehicle crash but were not fatally injured).
