Summary
This report presents the findings of a 1983 annual study on restraint system usage in the U.S. traffic population, conducted by Goodell-Grivas, Inc. for the National Highway Traffic Safety Administration (NHTSA). The research aimed to quantify the extent of safety belt, child safety seat, and helmet usage across various demographic and vehicle segments. The study was motivated by the need for consistent, long-term trend data on occupant protection behaviors to inform safety regulations and public awareness campaigns. The methodology involved field observations collected over a 14-month period (November 1982–December 1983) in 19 purposively selected U.S. cities representing diverse geographic regions. The study comprised four independent observational components. First, driver safety belt use was monitored at traffic signals and freeway exits, resulting in 146,305 observations. Second, passenger restraint use was observed at shopping mall entrances and exits, yielding 114,470 passenger observations. Third, a parking lot study examined the installation characteristics of 3,518 child safety seats. Fourth, helmet use was recorded for 21,414 motorcycle and 1,793 moped operators and passengers. Data collectors underwent rigorous training to ensure consistency with previous NHTSA studies, and observations were conducted during daytime hours across various times of day and days of the week. The findings revealed low overall restraint usage rates. Only 14.0% of drivers were observed wearing safety belts, with usage rates varying significantly by region (highest in the West, lowest in the Northcentral region), vehicle type (higher in imported and smaller vehicles), and driver demographics (higher among females and drivers aged 25–49). Passenger usage was similarly low: 10.5% of adults, 7.0% of teens, and 8.6% of subteens wore safety belts. Child safety seat usage was higher but inconsistent; 60.4% of infants and 37.8% of toddlers were in approved seats, though approximately one-quarter of restrained children were not properly harnessed. The installation study highlighted significant compliance issues, with 34% of toddler seats incorrectly belted and 80% of tether-required seats having unused or incorrectly used tethers. Helmet usage was 66.6% for motorcycle drivers and 34.7% for moped drivers. The significance of this report lies in its detailed baseline data on restraint behaviors during a period of evolving vehicle safety standards. The data indicate that while newer vehicles with combination lap-and-shoulder belts were driving a slight increase in proper restraint use, overall compliance remained low. The high rates of incorrect child seat installation and low helmet usage among moped operators suggest critical areas for regulatory intervention and educational outreach. The study provides essential empirical evidence for evaluating the effectiveness of existing safety laws and the adoption of passive restraint technologies.
