Summary

This report presents the findings of the 2014 statewide safety belt usage survey in Kentucky, conducted by the University of Kentucky Transportation Center. The study aims to establish the current statewide seat belt usage rate, documenting trends associated with the transition from secondary to primary enforcement laws enacted in 2006. The survey also tracks long-term historical data, noting that usage rates have risen from 4% in 1982 to 85% in 2013. The methodology adhered to National Highway Traffic Safety Administration (NHTSA) uniform criteria. Researchers selected 15 counties representing 20% of the state’s potential survey counties, ensuring geographic distribution across 12 highway districts. Jefferson and Fayette counties were automatically included due to high vehicle miles traveled (VMT), while other counties were randomly selected. Data was collected at 150 sites distributed across limited access, arterial, and local roadways, with site allocation proportional to VMT. Observers recorded belt usage for drivers and front-seat passengers in passenger cars, pickups, vans, and SUVs during one-hour observation periods between June and July 2014. The final sample comprised nearly 68,000 occupants. Usage rates were calculated using a four-step weighting process based on VMT and selection probabilities, with standard errors estimated via a jackknife approach. The 2014 statewide safety belt usage rate for all front-seat occupants was 86.1%, with a 95% confidence interval of ±0.7%. Driver usage was 86.7%, while passenger usage was 84.2%. Usage varied significantly by road class, ranging from 90.9% on limited access highways to 80.2% on local roads. Vehicle type also influenced rates, with SUVs showing the highest usage (89.2%) and pickup trucks the lowest (79.0%). County-level rates ranged from a high of 91.1% in Fayette County to a low of 69.4% in Clay County. The three counties with the lowest rates were located in the southeastern part of the state. Additionally, the survey observed a 60.7% helmet usage rate among motorcyclists, a significant decline from over 95% prior to the repeal of mandatory helmet laws in 1998. The report concludes that the 2014 rate represents the highest usage level since surveys began in 1982, reflecting a 1.1% increase from 2013. The authors attribute this growth to legislation, enforcement, and education efforts. They recommend maintaining primary enforcement strategies and targeting educational efforts toward counties and vehicle types with lower compliance, such as pickup trucks on local roads. The report also suggests considering modifications to the driver point system and increasing fines for non-compliance to further aid enforcement.

Key finding

The statewide safety belt usage rate for front-seat occupants in Kentucky was 86.1 percent in 2014, with drivers showing an 86.7 percent usage rate and front-seat passengers showing an 84.2 percent usage rate.
