This report presents estimates of alcohol involvement in fatal traffic crashes that occurred during 1992. The data are abstracted from FARS and represent a combination of actual blood alcohol concentration (BAC) test results and estimated BAC distributions for those drivers and nonoccupants for whom no BAC test results are available. The estimates are made using a model developed by the National Highway Traffic Safety Administration (NHTSA). In 1992, 36% of all fatalities occurred in crashes with a driver or nonoccupant with BAC of 0.10 or greater (in this report a BAC of 0.10 or greater is synonymous with intoxication). This represents a 22% reduction compared to 1982, when 46.3% of all fatalities occurred in crashes involving an intoxicated active participant. Occupant fatalities resulting from crashes involving an intoxicated driver or nonoccupant totalled 11.636. Less than one-half (45.4%) of the occupant fatalities in single-vehicle crashes involved an intoxicated driver, compared with 25.9% of the occupant fatalities in multi-vehicle crashes. An estimated 39.3% of the fatalities in nonoccupant crashes involved an intoxicated driver or nonoccupant. More than two-thirds (67.2%) of the fatally injured drivers in single-vehicle fatal crashes in weekend nights were drunk. Overall, male drivers involved in fatal crashes were almost twice as likely as female drivers to be drunk (24.7% versus 12.7%). Drivers of age 25-29 years exhibited the highest rates of intoxication (30.8%) followed by drivers of age 30-34 (30.6%). Drivers of age 16-20 years were intoxicated 17.5% of the time. Between 1982 and 1992, estimated reductions in the proportion of intoxicated drivers in fatal crashes are 29% for drivers of passenger cars, 25% for light trucks and vans, 44% for medium trucks, 71% for heavy trucks, and 12% for motorcycles. Drivers of motorcycles continue to exhibit a high rate of intoxication in fatal crashes, with 35.6% of involved drivers exhibiting a BAC of at least 0.10, compared to 25.6% for drivers of light trucks and vans, and 21.7% for drivers of passenger cars.
