Summary

This report presents the findings of an observational survey conducted by the Virginia Transportation Research Council to track safety belt and child safety seat usage among vehicle occupants in Virginia. The study was motivated by the need to evaluate the impact of statutory enactments, specifically the 1982 child safety seat law and the 1987 mandatory use law (MUL) for front-seat occupants, as well as enforcement campaigns and public information efforts. The research aimed to determine changes in usage rates following these laws and to identify user characteristics to inform future safety initiatives. The methodology involved observational surveys conducted at signalized intersections in two distinct phases: 1974–1977 and 1983–1990. Initially, data were collected only in Virginia’s four major metropolitan areas. Starting in 1987, the survey expanded to include nine smaller communities, referred to as "towns," to capture a broader statewide perspective. Observers recorded restraint usage, occupant age, and sex for passenger cars with Virginia license plates, excluding commercial and municipal vehicles. Data collection occurred during morning rush, mid-day, and afternoon rush hours. A significant procedural change occurred in 1987, where observers adopted stricter criteria for defining "correct" child safety seat use, requiring proper installation and harness usage rather than mere presence of a seat. The results indicate that the passage of statutes was the primary driver for increased restraint use. Prior to the laws, usage rates showed only small yearly increases. Following the 1982 child safety seat law, usage for children under four stabilized at approximately 66%. After the 1987 MUL, front-seat occupant usage peaked at nearly 62% in mid-1988, declined to 55% in 1989, and rose slightly to 57% in 1990. Usage was highest in northern Virginia and among older adults, while rear-seat occupants showed minimal increase, as they were not covered by the MUL. The study also found that a large proportion of child safety seats were misused, with incorrect usage rates ranging from 10% to over 40% depending on the year and strictness of observation criteria. Female drivers consistently exhibited higher usage rates than males. The authors conclude that legislative mandates were the most effective factor in increasing safety belt and seat usage. To further improve compliance, the report recommends directing public information and enforcement efforts toward rural areas, smaller communities, rear-seat occupants, and young males. Additionally, it suggests amending the mandatory use law to include rear-seat occupants, given their persistently low usage rates.

Key finding

Front seat safety belt use peaked at 61.8% six months after the mandatory use law took effect, then declined significantly to 55.1% in 1989 before rising slightly to 56.8% in 1990.
