Summary

This research note reports the findings of the 1996 National Occupant Protection Use Survey (NOPUS), conducted by the National Highway Traffic Safety Administration (NHTSA) to estimate safety belt and motorcycle helmet use across the United States. The study was motivated by the need for a nationally representative, probability-based assessment of occupant protection, complementing state-level surveys which often rely on convenience samples or varying methodologies. The NOPUS is composed of three studies; this document specifically details the results of the moving traffic study, which measures shoulder belt use in moving vehicles. Data collection occurred from October to December 1996 at 3,290 sites nationwide. Observers stationed at intersections and exit ramps recorded belt use for drivers and front-seat passengers of passenger cars and light trucks, as well as helmet use for motorcyclists. The study utilized a multi-stage probability sampling design, selecting counties based on region, urbanization, and belt use levels, followed by random selection of roadways and specific sites. A total of 176,651 passenger cars, 93,786 light trucks, and 710 motorcycles were observed during daylight hours across all days of the week. The overall observed safety belt use rate in 1996 was 61.3%, an increase from 58.0% in 1994. Use rates varied by vehicle type, with passenger cars at 64.4% and light trucks at 56.4%. Regional analysis indicated the highest use in the West (66.8%) and the lowest in the Midwest (55.4%). Comparisons with 1994 data revealed that while belt use increased across all categories, only the increase in light truck driver use (nearly 7%) was statistically significant. Motorcycle helmet use remained relatively stable at 64.1%, though drivers showed a slight decrease while passengers showed an increase compared to 1994. The paper also compares NOPUS findings with national estimates derived from state surveys, which reported a 68% belt use rate in 1996. The authors note that while direct comparison is difficult due to differences in vehicle coverage and sampling methods, the state-based estimate falls within the NOPUS confidence interval. The study concludes that NOPUS provides a unique, statistically rigorous source of detailed national data on restraint use by vehicle type and demographic characteristics, whereas state surveys remain essential for monitoring individual state progress. Future NOPUS surveys will depend on budgetary considerations and the need for this level of detailed analysis.

Key finding

The overall observed safety belt use rate in 1996 was 61.3%, representing a statistically significant increase from the 58.0% rate observed in 1994.
