Summary

This report, published by the National Highway Traffic Safety Administration (NHTSA) in 1994, presents statistical data on alcohol involvement in U.S. traffic crashes for the year 1993. The document aims to quantify the prevalence of alcohol-related fatalities and injuries, analyze demographic and temporal trends, and evaluate the impact of legislative measures such as minimum drinking age laws. NHTSA defines a crash as alcohol-related if any driver or nonoccupant has a blood alcohol concentration (BAC) of 0.01 g/dl or greater, and defines intoxication as a BAC of 0.10 g/dl or greater. The analysis relies on police-reported crash data and NHTSA estimates. The report compares 1993 statistics with data from 1983 and 1992 to identify long-term trends. It categorizes data by driver age, sex, vehicle type, time of day, and day of the week. Additionally, it examines the driving records of fatally injured drivers and the intoxication rates of pedestrians and pedalcyclists. In 1993, there were 17,461 fatalities in alcohol-related crashes, representing 44 percent of all traffic fatalities. This figure marked a 2 percent decrease from 1992 and a 26 percent reduction from the 23,646 alcohol-related fatalities recorded in 1983. Alcohol was involved in 7 percent of all crashes and resulted in approximately 289,000 injuries. Intoxication rates varied significantly by demographic and context. Drivers aged 21 to 24 had the highest intoxication rate in fatal crashes (30.7 percent), while motorcycle operators had the highest rate among vehicle types (32.9 percent). Conversely, large truck drivers had the lowest rate (1.7 percent). Alcohol involvement was substantially higher at night (65.3 percent of fatal crashes) than during the day (19.5 percent) and on weekends (56.9 percent) compared to weekdays (33.5 percent). From 1983 to 1993, intoxication rates declined for all driver age groups, with the largest decreases observed in drivers aged 16–20 (47 percent decline) and those 65 and older (44 percent decline). The report highlights significant behavioral and legal correlations. Only 16.0 percent of fatally injured intoxicated drivers used safety belts, compared to 41.5 percent of sober drivers. Fatally injured intoxicated drivers were six times more likely to have prior driving while intoxicated (DWI) convictions than sober drivers. Among pedestrians aged 16 and older killed in crashes, more than one-third were intoxicated, with the highest rates among those aged 25–34. The document concludes by noting that minimum drinking age laws, implemented in all states by 1993, are estimated to have reduced traffic fatalities involving drivers aged 18–20 by 13 percent and saved approximately 13,968 lives since 1975.

Key finding

Alcohol was involved in 44 percent of fatal crashes in 1993, with intoxication rates being over three times higher at night than during the day and highest among drivers aged 21 to 24.
