Abstract

The data in this traffic safety fact sheet provide estimates of alcohol involvement in fatal crashes for the USA and individually for the 50 states, the District of Columbia, and Puerto Rico (not included in the national totals). These estimates are based on data from the National Highway Traffic Safety Administration's (NHTSA's) Fatality Analysis Reporting System (FARS). Unfortunately, known blood alcohol concentration (BAC) test results are not available for all drivers and nonoccupants involved in fatal crashes. In 2001, NHTSA began using a revised method, namely multiple imputation, to estimate missing information about BAC levels for persons involved in fatal crashes. The alcohol estimates in this fact sheet are based on the new imputation method. Because many states have adopted 0.08 g/dl as the legal threshold for alcohol intoxication, NHTSA now estimates alcohol involvement in the following three categories: 0.00 g/dl, no alcohol; 0.01 to 0.07 g/dl, impaired; and 0.08+, intoxicated. The estimates presented include a mix of both known and estimated BACs. Both 1982 and 2001 BAC data are provided.
