Summary
This report, titled *Alcohol and Highway Safety 1978: A Review of the State of Knowledge*, was prepared by Ralph K. Jones and Kent B. Joscelyn for the National Highway Traffic Safety Administration (NHTSA). The study addresses the critical public health issue of alcohol-impaired driving, which contributes significantly to motor vehicle crashes, a leading cause of death in the United States. Motivated by the need to update the scientific understanding established in a landmark 1968 Department of Transportation report, this comprehensive review aims to summarize existing knowledge regarding the nature of the alcohol-crash problem, the physiological and behavioral effects of alcohol, the characteristics of drinking drivers, and the efficacy of various countermeasure programs. The methodology employed is a systematic review and analysis of scientific literature rather than primary data collection. The authors examined epidemiologic studies, experimental laboratory studies, and evaluations of countermeasure programs conducted primarily between 1968 and 1977. The review focuses on four key areas: defining the magnitude of the problem through epidemiologic data; analyzing the biochemical, physiological, and behavioral effects of alcohol on driving performance; characterizing the demographic and behavioral profiles of drivers involved in alcohol-related crashes; and evaluating past societal responses, including legal, health, public information, and technological approaches. The authors prioritized scientifically reliable studies to ensure factual accuracy and minimize speculation. The findings establish that alcohol is a major factor in highway crashes, with epidemiologic data confirming that drinking drivers are overrepresented in crash statistics compared to the general driving population. The report details how blood alcohol concentration (BAC) correlates with increased crash risk and impairment of both simple neuromuscular functions and complex cognitive processes. It identifies specific demographic groups and drinking patterns associated with higher crash risks. Furthermore, the review evaluates various intervention strategies, noting that while legal enforcement and health-based approaches have been utilized, many programs lacked rigorous evaluation. The report also projects future trends, suggesting that without effective interventions, the alcohol-crash problem would persist or worsen in the 1980s. The significance of this report lies in its role as a definitive synthesis of the state of knowledge at the time, providing a factual basis for policymakers and researchers. It concludes by identifying priorities for future research and action, emphasizing the need for more rigorous evaluation of alcohol-safety programs and a better understanding of the specific mechanisms linking alcohol consumption to crash involvement. By consolidating disparate research findings into a single volume, the report facilitates more informed decision-making regarding laws, enforcement strategies, and public education campaigns aimed at reducing alcohol-related highway fatalities.
Key finding
The report establishes that drinking drivers are significantly overrepresented in fatal and nonfatal crashes compared to their presence in the general driving population, confirming alcohol as a major contributor to highway fatalities.
