Summary

This report presents findings from the 1998 Motor Vehicle Occupant Safety Survey (MVOSS), the third in a series of biennial national telephone surveys conducted for the National Highway Traffic Safety Administration (NHTSA). The study aims to assess seat belt usage patterns, attitudes toward occupant protection, and public support for seat belt laws and enforcement. Data were collected by Schulman, Ronca & Bucuvalas, Inc., between November 1998 and January 1999, using two questionnaires administered to a randomly selected national sample of approximately 4,000 persons aged 16 and older. The results are weighted to yield national estimates and are compared against concurrent NHTSA observational surveys and previous MVOSS data from 1994 and 1996. The survey found that 79% of drivers reported wearing seat belts "all the time," a figure that closely matched observed use rates when adjusted for self-reporting inconsistencies. Usage was lower among males, low-income households, pickup truck drivers, and heavier individuals. Hispanic drivers reported higher usage (85%) than non-Hispanics (79%), while Black drivers reported slightly lower usage (75%) than whites (79%). Passenger usage was significantly lower, with 74% of front-seat passengers and only 43% of back-seat passengers reporting consistent use. Reasons for non-use varied by frequency: part-time users cited short distances or forgetting, whereas non-users cited discomfort, personal freedom, or fatalistic beliefs. Injury avoidance was the primary reason for use among frequent users, while legal compliance was more frequently cited by Black and Hispanic respondents. Attitudinal analysis revealed that 86% of the public favored seat belt laws for front-seat passengers, with 78% of those also supporting laws for rear-seat adults. Support for standard enforcement (allowing police to stop vehicles solely for seat belt violations) increased to 58%, up from 52% in 1996. Reported seat belt use was higher in states with standard enforcement (85%) compared to secondary enforcement (75%). Demographic differences in attitudes were pronounced; Black and Hispanic respondents were more likely to believe seat belts could be harmful and more likely to feel self-conscious wearing them if friends did not, yet they also showed stronger support for strict enforcement and fines. Conversely, higher education levels correlated with greater belief in the utility of seat belts and less fatalism. The study concludes that while seat belt use has increased steadily from 74% in 1994 to 79% in 1998, significant gaps remain in passenger usage and among specific demographic groups. The findings suggest that enforcement type and perceived legal coverage significantly influence compliance. Furthermore, the divergence between high support for laws and lower actual usage among certain groups highlights the need for targeted interventions addressing discomfort, risk perception, and social norms. The data provide a baseline for evaluating the effectiveness of public service campaigns, such as the "Vince and Larry" crash dummy ads, which reached 58% of the population with a clear safety message.

Key finding

Adjusted self-reported seat belt use rates matched observed rates, and usage was significantly higher in states with standard enforcement laws compared to secondary enforcement.
