The role of heavy drinking in the risk of traffic fatalities.
Recent studies have identified a "hard core" of drinking drivers who do not fit a "social" drinker profile and may require medical intervention. This article builds on these studies by quantifying the role of heavy drinking in motor vehicle fatalities. Data on male alcohol-involved fatally injured drivers (AIFIDs) were obtained from the U.S. Fatal Accident Reporting System (FARS) for the years 1989-1990 (n = 8876). The AIFIDs were grouped into either a "heavy" or "light" drinking category based on drinking behaviors inferred from prior driving records and blood alcohol concentrations (BAC). The majority of male AIFIDs were between the ages of 20-39 (70%). Sixty-five percent had a BAC of 150 mg/dl or greater, and 41% had a BAC in excess of 200 mg/dl. AIFIDs with high BACs were more likely to have histories of DUI convictions and license suspensions than AIFIDs with low BACs. According to the study's criteria, 73% percent of the AIFIDs could be classified as "heavy" drinkers. There were no driving variables that differentiated the heavy and light drinker groups, indicating that heavy drinking per se is the primary factor that distinguishes the groups. Male alcohol-involved fatally injured drivers are comprised mostly of heavy drinkers who may suffer from serious drinking problems or alcoholism. Successful interventions may require medical treatment as well as punitive criminal justice policies.
