Summary

This report presents the findings of the 2005 safety belt and child safety seat usage survey conducted in Kentucky by the University of Kentucky Transportation Center in cooperation with the Kentucky State Police. The study aims to establish statewide usage rates to evaluate the impact of the 1994 mandatory safety belt law and ongoing enforcement campaigns, such as “Buckle Up Kentucky.” The research addresses the need for accurate, representative data to inform policy decisions regarding enforcement strategies, particularly the potential shift from secondary to primary enforcement. The methodology involved observational data collection at 200 randomly selected sites across Kentucky, chosen to represent 85% of the state’s population. Sites were stratified by geographic region (West, North, East) and roadway functional classification (e.g., rural interstate, urban arterial) using the Highway Performance Monitoring System. Trained observers collected data for two hours at each site, recording restraint usage for drivers, front-seat passengers, and children under four years of age. The analysis weighted individual site results by vehicle miles traveled to calculate statewide percentages. The survey also included observations of motorcycle and bicycle helmet usage. The results indicate that the statewide safety belt usage rate for all front-seat occupants was 66.7% in 2005, a slight increase from 66.0% in 2004 and significantly higher than the 42% recorded in 1993 prior to the statewide law. Driver usage was 66.8%, while front-seat passenger usage was 66.2%. Usage varied by region, with the highest rates in the North (71.5%) and lowest in the East (56.2%). Vehicle type significantly influenced usage; vans and SUVs had rates above 73%, whereas pickup trucks had the lowest rate at 54.1%. Child restraint usage for those under four was 94.4%, with higher compliance in rear seats. Motorcycle helmet usage was 59%, reflecting a decline since the repeal of the mandatory helmet law in 1998, while bicycle helmet usage remained low at 14%. The authors conclude that while usage rates have reached historic highs, the benefits of secondary enforcement are limited, as evidenced by a drop in usage after enforcement campaigns ended. They recommend modifying the law to allow primary enforcement for all occupants, or at minimum for drivers in the graduated license program, citing public support and the high compliance rates seen in child restraint laws which utilize primary enforcement. The report also suggests targeted enforcement in the eastern region and for pickup truck occupants, and considers reinstating a motorcycle helmet law.

Key finding

The statewide safety belt usage rate for all front-seat occupants in Kentucky was 66.7 percent in 2005, while the usage rate for children under four years of age was 94.4 percent.
