Summary

This report presents the findings of an observational survey on safety belt and child safety seat usage in Virginia, serving as the 1988 update to a series conducted between 1983 and 1988. The study was motivated by the need to evaluate the impact of two legislative mandates: the Child Safety Seat Law, effective January 1, 1983, and the Mandatory Use Law (MUL), effective January 1, 1988. The primary objectives were to determine how these laws affected usage rates, analyze user characteristics, and provide data for future safety programs. The methodology involved field observers surveying vehicle occupants in four major urban areas and nine smaller towns during June of each year. Observers recorded restraint use at signalized intersections during morning, mid-day, and afternoon periods. Data were categorized by occupant seat position, sex, age, and geographic location. A significant procedural change occurred in 1987, where observers received specialized training to more strictly identify incorrect child safety seat usage, leading to a more rigorous classification of misuse compared to previous years. The results indicated a sharp increase in safety belt usage following the implementation of the MUL. In 1988, statewide belt use rates reached 65.5% for drivers and 46.8% for passengers, nearly doubling the pre-MUL rates of 34.3% and 28.9%, respectively. Urban areas showed higher compliance than towns, with 68.9% of urban drivers and 50.8% of urban passengers using belts in 1988. Conversely, town drivers and passengers had usage rates of 55.8% and 37.1%. Child safety seat usage remained stable at approximately two-thirds of infants, though misuse rates were significant, with 21.4% of seats incorrectly used in 1988. The study also found that female drivers and older adults had the highest usage rates, while rear-seat passengers showed little increase in usage, as the MUL did not apply to them. The authors concluded that the MUL had a major positive influence on safety belt adoption. They recommended that future efforts to improve safety habits should target residents of smaller communities and rural areas, rear-seat occupants, and males aged 17 to 30. Additionally, resources should be directed toward areas where usage rates have declined or remain below half of the observed averages. The report highlights the strong correlation between driver and passenger belt use, suggesting that driver compliance significantly influences passenger behavior.

Key finding

The implementation of Virginia's Mandatory Use Law in 1988 caused statewide safety belt usage rates to nearly double, rising from 34.3% for drivers and 28.9% for passengers to 65.5% and 46.8% respectively.
