Summary

This report presents the findings of the 2009 safety belt usage survey in Kentucky, conducted by the Kentucky Transportation Center. The study aimed to establish statewide safety belt and child safety seat usage rates, continuing a long-term documentation of compliance following legislative changes, specifically the shift from secondary to primary enforcement of mandatory safety belt laws in 2006. The research sought to evaluate current usage levels and compare them against historical data to assess the impact of enforcement and education campaigns. Data were collected at 160 randomly selected sites across 18 counties, utilizing a multi-stage area probability sampling design aligned with National Highway Transportation Safety Administration (NHTSA) guidelines. Observers recorded safety belt usage for drivers and front-seat passengers, as well as child restraint usage for children under four years of age. The sample included 81,886 front-seat occupants. Site selection was stratified by county population and roadway functional classification (interstates, principal arterials, minor arterials, and collectors), with allocations proportional to vehicle miles traveled. Data collection occurred during daylight hours at intersections or overpasses to ensure accurate observation of occupants in stopped or slow-moving vehicles. The 2009 statewide safety belt usage rate for all front-seat occupants was 79.7 percent, a significant increase from 73.3 percent in 2008. Usage rates varied by roadway type, with the highest compliance (86.0 percent) on interstates and parkways and the lowest (72.4 percent) on collector roads. Vehicle type also influenced usage; vans had the highest rate (83.7 percent), while pickup trucks had the lowest (69.0 percent). Geographically, Fayette County recorded the highest usage (85.9 percent), while Knott County had the lowest (65.6 percent). Child safety seat usage for children under four remained exceptionally high at 98.6 percent. Additionally, motorcycle helmet usage was observed at 63.7 percent, reflecting a decline since the repeal of the mandatory helmet law in 1998. The findings indicate that safety belt usage in Kentucky reached its highest level since surveys began in 1982, correlating with the implementation of primary enforcement and ongoing education efforts. The substantial increase from 2008 to 2009 suggests that enforcement strategies are effective. The report concludes that maintaining current education and enforcement initiatives is crucial, while highlighting specific areas for targeted intervention, such as rural counties and pickup truck drivers, where usage rates remain lower. The data also confirm the sustained high compliance for child restraints, likely due to long-standing primary enforcement for this demographic.

Key finding

The statewide safety belt usage rate for front-seat occupants in Kentucky was 79.7 percent in 2009, with usage rates highest on interstates (86.0 percent) and lowest for pickup trucks (69.0 percent).
