Chance an Alcohol-Impaired Traffic Fatality Involved BAC 0.15+ (2023)

NHTSA's 2023 traffic crash summary reports 8,272 of 12,429 alcohol-impaired-driving fatalities for this measure. The probability shown here is 67% of alcohol-impaired-driving fatalities, using alcohol-impaired-driving fatalities as the denominator. Among alcohol-impaired-driving fatalities, NHTSA reported 67 percent were in crashes with at least one driver at BAC .15 g/dL or higher.

This fact should be read carefully because traffic safety denominators change the meaning of the number. Annual population rates answer, "how common was this outcome among people in the United States during 2023?" Per-mile rates answer, "how often did this outcome occur per vehicle mile traveled?" Conditional percentages answer, "among crashes or fatalities already in a specific category, how often did this factor appear?" Mixing those denominators would create misleading comparisons.

The decision value is exposure control. Traffic risk is not just about whether someone owns a car; it changes with miles driven, speed, alcohol use, seat belt use, road type, time of day, vehicle type, age, local infrastructure, and whether the person is walking, cycling, riding a motorcycle, or riding in a passenger vehicle. For this topic, practical prevention usually centers on recognizing that severe impairment drives much of the fatality burden and planning alternatives before alcohol consumption starts.

The 2023 NHTSA summary uses FARS for fatal crashes and CRSS for estimated nonfatal injuries. FARS includes traffic crashes on public trafficways that involve a motor vehicle in transport and result in a death within 30 days. CRSS injury figures are estimates, not exact counts, so they are best used as national benchmarks for decision framing rather than as personalized forecasts.
