About the National Data
Data Source: Fatality Analysis Reporting System (FARS), DOT/NHTSA
Baseline: 29.0 percent of motor vehicle crash deaths involved a driver with a BAC of 0.08 g/dL or higher in 2017
Target: 28.3 percent
Minimal statistical significance
The National Highway Traffic Safety Administration (NHTSA) defines a fatal crash as alcohol-impaired driving if a driver involved in the crash has a measurable or estimated blood alcohol concentration (BAC) of 0.08 g/dL or above. Thus, all fatalities that occur in a crash involving an alcohol-impaired driver are called alcohol-impaired-driving fatalities. BAC is measured as a percentage by weight of alcohol in the blood (expressed as grams per deciliter). An elevated BAC level (0.08 g/dL and higher) indicates that enough alcohol was consumed by the person tested to impair normal functions. Only deaths that occur within 30 days of the motor vehicle crash are included (less than 2 percent of the total number of deaths occur after 30 days). FARS data are obtained solely from a State's existing documents, including police crash reports, death certificates (coded to ICD-10 V30-V39 [.4-.9], V40-V49 [.4-.9], V50-V59 [.4-.9], V60-V69 [.4-.9], V70-V79 [.4-.9], V81.1, V82.1, V83-V86 [.0-.3], V20-V28 [.3-.9]. V29 [.4-.9], V12-V14 [.3-.9], V19 [.4-.6], V02-V04 [.1, .9], V09.2, V80 [.3-.5], V87 [.0-.8], V89.2), vehicle registration files, and hospital medical reports.
