Summary

This 1983 report by the National Highway Traffic Safety Administration (NHTA) investigates the factors contributing to a significant decline in traffic fatalities observed in 1982. The study aims to determine if changes in public travel patterns, driving behaviors, or attitudes toward safety issues—specifically drunk driving and seat belt usage—accounted for this reduction. The research was conducted by Tarrance & Associates to provide data-driven guidance for national highway safety programs. The study employed a three-phase methodology. Phase I involved focus groups to develop the survey instrument. Phase II consisted of a nationwide telephone survey of 1,200 American adults (including a re-contacted sample of 200 respondents from an 1981 survey) conducted between March and April 1983. Phase III utilized additional focus groups to interpret the quantitative data and assess the qualitative intensity of the findings. The survey covered attitudes toward drunk driving, occupant protection device usage, and driving patterns. Key findings indicate that the public identified reducing drunk driving and increasing seat belt use as the two most critical highway safety issues. Respondents attributed the recent drop in traffic deaths primarily to "lower speeds" and "less drunk driving." Regarding seat belts, there was a positive shift in usage; approximately three times as many respondents reported wearing belts more often than less often compared to the previous year. Drivers cited safety, awareness of drunk drivers, and protecting children as primary reasons for increased use, while discomfort and broken habits drove decreased use. Concerning alcohol, about 63% of adults reported drinking occasionally. Of those, 20% drove within one hour of drinking at least monthly, while 60% never did. Notably, 24% of those who drink and drive reported decreasing this behavior in the past year, often due to stricter laws or increased awareness. Additionally, 85% of respondents were aware of Mothers Against Drunk Driving (MADD), with 55% believing the organization was succeeding. The study concludes that public perception of risk and community efforts significantly influence driving behavior. The authors recommend developing messages that explain how inertial seat belts function to build user confidence. They suggest positioning seat belt usage as part of a preventive health regimen and leveraging the public’s positive response to community-led initiatives like MADD. Furthermore, the report advises that programs targeting drunk driving should also emphasize seat belt use as a defense against impaired drivers, fostering similar community-based efforts for occupant protection.

Key finding

About 63% of the adult population drinks alcoholic beverages, with 20% driving within one hour of drinking at least once a month and 29% doing so one to four times a year.
