Summary

This report presents the findings of an observational survey conducted in the summer of 1994 to assess child safety seat usage in Virginia’s four metropolitan areas, which house 54% of the state’s population. The study was commissioned by the Transportation Safety Administration of the Department of Motor Vehicles to monitor compliance with state law requiring children under age four to be secured in child restraint devices. The research aimed to categorize usage as correct, incorrect, or non-use, and to identify regional variations and trends compared to 1993 data. Data were collected at 34 signalized intersections across the northern, eastern, central, and western regions. Survey teams observed passenger cars in the curb lane, using visual cues such as height (under 40 inches) and weight (under 40 pounds) to identify children under age four. Usage was recorded based on features visible from outside the vehicle, including harness clipping, seat direction, and belt routing. The methodology acknowledged that incorrect use rates were likely underestimated because observers could not verify the tension of lap/shoulder belts securing the seats. The results indicated that 64.0% of observed children were in correctly used safety seats, 25.7% were not using a seat, and 10.4% were using a seat incorrectly. Correct usage was significantly higher in rear seats (70.1%) than in front seats (49.3%), with only 29.4% of children riding in the front. Regional disparities were evident: the eastern area had the highest correct use rate (78.6%) and lowest non-use rate (13.8%), while the central area had the highest non-use rate (39.0%) and lowest correct use rate (48.8%). The western area exhibited the highest incorrect use rate (20.7%). Compared to 1993, the 1994 survey showed an overall improvement, with correct use increasing from 48.9% to 64.0%, and both incorrect and non-use rates declining. The authors conclude that despite overall improvements, high rates of non-use and misuse persist, particularly in the central and western regions. They attribute the underestimation of misuse to the limitations of in-traffic surveys. The report recommends implementing comprehensive statewide educational programs, increasing enforcement, and developing local initiatives to identify and correct improper seat installation. It emphasizes the need for ongoing public information campaigns to address the constantly changing population of infants and toddlers.

Key finding

Correct child safety seat use was 64.0% overall, with rear seat usage (70.1%) significantly higher than front seat usage (49.3%).
