Summary

This report presents the findings of the 2008 statewide safety belt and child safety seat usage survey in Kentucky, conducted by the Kentucky Transportation Center. The study aims to establish current usage rates and evaluate the impact of legislative changes, specifically the transition from secondary to primary enforcement of safety belt laws enacted in 2006. The research continues a long-term observational series that began in 1982, providing data to assess compliance trends following the implementation of fines for non-compliance starting in January 2007. Data were collected at 200 randomly selected sites across Kentucky, stratified by geographic region and roadway functional classification to ensure a representative sample. Observers recorded safety belt usage for drivers and front-seat passengers, as well as restraint usage for children under four years of age in both front and rear seats. The survey also included observations of motorcycle and bicycle helmet usage. Data collection occurred during daylight hours on weekdays and weekends, with two hours of observation per site. The results were weighted by vehicle miles traveled to calculate statewide estimates, with a total sample size of 130,335 front-seat occupants. The 2008 statewide safety belt usage rate for all front-seat occupants was 73.3%, representing an increase from 71.8% in 2007 and a significant rise from 42% in 1993, prior to the statewide mandatory law. Driver usage was 73.9%, while front-seat passenger usage was 70.9%. Usage varied significantly by location and vehicle type; rural interstates had the highest compliance (81.8%), while rural local roads had the lowest (64.6%). Pickup trucks exhibited the lowest usage rate among vehicle types at 60.4%, whereas vans had the highest at 79.1%. Regionally, the North region had the highest usage (77.2%), and the East region had the lowest (63.4%). Child restraint usage for children under four remained high at 98%, with higher compliance observed in rear seats compared to front seats. Motorcycle helmet usage was 58%, and bicycle helmet usage was 34% based on a small sample. The findings indicate that the shift to primary enforcement and associated enforcement campaigns contributed to increased safety belt usage, which reached its highest level since surveys began. The report concludes that continued enforcement and public awareness are necessary to maintain these gains. It recommends targeted enforcement efforts in the East region and among pickup truck occupants, where compliance is lowest. Additionally, the low motorcycle helmet usage following the repeal of the mandatory helmet law is linked to increased injuries and fatalities, leading to a recommendation for reconsidering mandatory helmet legislation.

Key finding

The statewide safety belt usage rate for all front seat occupants in Kentucky was 73.3 percent in 2008, with usage lowest at 51.5 percent for pickup truck occupants in the eastern region.
