Summary

This report, titled *Alcohol and Highway Safety 1984: A Review of the State of the Knowledge*, serves as an interim update to the National Highway Traffic Safety Administration’s (NHTSA) 1978 comprehensive review. Motivated by growing public concern from organizations such as Mothers Against Drunk Driving (MADD) and the implementation of new federal and state legislation, the document aims to document significant developments in alcohol safety research between January 1978 and December 1982. The update focuses on integrating new data systems, such as the Fatal Accident Reporting System (FARS) and the National Accident Summary System, to provide a current assessment of the alcohol-crash problem and the effectiveness of countermeasures. The methodology involves a synthesis of existing scientific literature rather than new primary data collection. The authors, led by Robert B. Voas, revised the original 1978 report by Ralph K. Jones and Kent B. Joscelyn to include new references and reorganize content to emphasize general deterrence. The review categorizes research into five approaches: determining alcohol consumption and elimination, laboratory studies of behavior, driving performance studies, epidemiological studies of driver populations, and naturalistic field studies observing the effects of legal and social changes. The report highlights methodological challenges, particularly the lack of comprehensive epidemiological studies comparing crash-involved drivers with control groups exposed to identical driving environments, and the difficulty in translating laboratory findings to real-world driving tasks. Key findings establish that alcohol is a significant factor in highway crashes, with data from FARS and other sources quantifying the incidence of alcohol involvement in fatal and non-fatal accidents. The report details the physiological effects of alcohol, including absorption rates and blood alcohol concentration (BAC) metrics. It identifies specific demographic and behavioral characteristics associated with drinking drivers, noting variations by age, sex, time of day, and drinking frequency. Crucially, the review presents evidence that raising the minimum legal drinking age reduces teenage alcohol-related crashes and that increased enforcement and stricter penalties contribute to general deterrence. The analysis also evaluates various remedial programs, including vehicle-roadway engineering, exposure reduction, criminal justice initiatives, health care treatments, and public information campaigns. The significance of this report lies in its role as a technical basis for federal recommendations and state-level alcohol safety programs. By consolidating the state of knowledge up to 1982, it provides policymakers with evidence-based insights into the efficacy of different countermeasures. The report concludes by identifying research needs, particularly in general deterrence, prevention, and impairment information, and outlines new directions for integrated alcohol programs. It underscores the importance of rigorous evaluation in program development and highlights the progress made through legislative changes and enhanced enforcement strategies, offering a framework for future efforts to reduce alcohol-related highway losses.

Key finding

The report provides a comprehensive review of the state of knowledge on alcohol and highway safety, documenting the establishment of new national data systems and evaluating the effectiveness of various countermeasures like raising the drinking age and enforcement programs.
