Summary

This report presents the findings of the 2010 safety belt usage survey in Kentucky, conducted by the University of Kentucky Transportation Center. The study aims to establish statewide safety belt and child safety seat usage rates, documenting trends following the 1994 enactment of secondary enforcement laws and the 2006 transition to primary enforcement. The research also tracks motorcycle helmet usage and introduces a preliminary assessment of distracted driving. Data were collected at 160 randomly selected sites across 18 counties, chosen using a multi-stage area probability sampling method based on vehicle miles traveled (VMT) and county population. Observers recorded restraint usage for drivers and front-seat passengers, as well as children under four years of age in both front and rear seats. The survey utilized a stratified design covering four road functional classifications: interstates/parkways, principal arterials, minor arterials, and collectors. Data collection occurred during daylight hours, with observers trained to ensure accuracy and consistency. The final statewide usage rates were calculated by weighting individual site data according to their representation of total statewide VMT. The 2010 statewide safety belt usage rate for all front-seat occupants was 80.3%, statistically similar to the 79.7% rate in 2009 but significantly higher than the 73.3% rate in 2008. Driver usage was 81.0%, while front-seat passenger usage was 77.3%. Usage varied by road type, with the highest rates on interstates and parkways (86.7%) and the lowest on collector roads (73.4%). Vehicle type also influenced compliance; vans had the highest usage rate (84.6%), while pickup trucks had the lowest (70.0%). Child safety seat usage for children under four remained high at 96.4%. In contrast, motorcycle helmet usage declined to 50% in 2010, down from 64% in 2009, reflecting the repeal of mandatory helmet laws in 1998. Additionally, 7.6% of drivers were observed engaging in distracted driving behaviors, such as using cell phones. The study concludes that safety belt usage in Kentucky has increased dramatically since 1982, correlating with legislative changes and enforcement efforts. The high compliance rates support the continuation of primary enforcement laws and educational campaigns. However, the data highlight disparities in usage by vehicle type and geographic location, suggesting that future enforcement efforts should target pickup truck drivers and rural areas with lower compliance. The decline in motorcycle helmet usage underscores the impact of legislative repeal on safety behaviors.

Key finding

The statewide safety belt usage rate for front-seat occupants in Kentucky was 80.3 percent in 2010, with usage varying significantly by vehicle type (84.6 percent for vans versus 70.0 percent for pickup trucks) and roadway classification (86.7 percent on interstates versus 73.4 percent on collector roads).
