Summary

This 1986 report by the National Highway Traffic Safety Administration (NHTSA) addresses public knowledge, acceptance, and compliance regarding occupant protection systems. The study was motivated by an amendment to Federal Motor Vehicle Safety Standard 208, which mandated automatic occupant protection systems in new cars unless states representing two-thirds of the U.S. population enacted mandatory safety belt use laws (MULs) by 1989. The research aimed to inform national public information campaigns by assessing public attitudes toward automatic safety belts, air bags, and MULs. The researchers conducted a telephone survey of a nationally representative sample of 1,213 individuals aged 18 and older who drive or ride in cars. Data collection occurred between January and February 1986 using random digit dialing, with stratification by gender and geography to ensure adequate representation and allow for comparisons between states with and without MULs. The questionnaire assessed awareness, knowledge, preferences, and willingness to pay for automatic belts and air bags, as well as support for and compliance with MULs. Respondents were provided with standardized descriptions of the technologies to ensure a common understanding. The findings revealed significant gaps in public understanding and varying levels of acceptance. Only 40% of respondents had heard of automatic safety belts; those aware expressed concerns about malfunctions and being trapped in accidents. The majority preferred manual belts, and 40% indicated they would unbuckle automatic belts, while 20% would permanently disconnect them. In contrast, air bags were widely preferred, with one-third of respondents willing to pay approximately $300 for them. However, concerns remained regarding reliability and the need for seat belts to complement air bags. Regarding MULs, the majority of the public supported them, citing life-saving benefits. States with MULs in effect reported significantly higher safety belt usage, particularly when the laws included fines and were perceived as strictly enforced. In states without MULs, two-thirds of rare users reported they would increase usage if such laws were enacted. The study concludes that while the public supports MULs and recognizes the protective value of air bags, automatic safety belts face significant resistance due to lack of familiarity and fear of malfunction. The report recommends targeted educational campaigns to address misconceptions about automatic belts and clarify the complementary role of seat belts with air bags. It also emphasizes that the effectiveness of MULs depends on the inclusion of fines and strict enforcement. The findings suggest that automatic protection systems and MULs are not mutually exclusive but rather complementary strategies for enhancing occupant safety.

Key finding

Mandatory safety belt use laws significantly increased reported belt usage, especially when accompanied by fines and perceived strict enforcement, while the public preferred manual belts over automatic systems but favored air bags.
