Summary

This report presents the findings of the 2004 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 current usage rates to evaluate the effectiveness of the statewide mandatory safety belt law enacted in 1994 and associated enforcement campaigns. The research addresses the need for ongoing monitoring of compliance, particularly in light of the law’s secondary enforcement status and the potential benefits of shifting to primary enforcement. Data were collected through observational surveys at 200 randomly selected sites across Kentucky, chosen to represent 85% of the state’s population. The sampling design, aligned with National Highway Traffic Safety Administration guidelines, stratified locations by geographic region (West, North, East) and roadway functional classification (e.g., rural interstate, urban arterial). Observers recorded restraint usage for drivers, front-seat passengers, and children under four years of age (both front and rear seats) during two-hour daylight sessions at each site. The final statewide rates were calculated by weighting site-specific data according to vehicle miles traveled. The survey also included observations of motorcycle and bicycle helmet usage. The 2004 statewide safety belt usage rate for all front-seat occupants was 66.0%, a slight increase from 65.5% in 2003 and significantly higher than the 42% recorded in 1993 prior to the statewide law. Usage varied by region, with the highest rate in the North (70.5%) and the lowest in the East (56.7%). It also varied by vehicle type, with sport utility vehicles showing the highest compliance (73.3%) and pickup trucks the lowest (50.7%). Child safety seat usage for children under four remained high at 96.0%, with rear-seat usage notably higher than front-seat usage. Motorcycle helmet usage was 58%, reflecting a decline following the 1998 repeal of the mandatory helmet law, while bicycle helmet usage was extremely low at 8%. The authors conclude that while usage rates have improved since 1994, 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, to maximize compliance. The report also suggests targeted enforcement and education in the eastern region and for pickup truck occupants, and considers reinstating a mandatory motorcycle helmet law given the significant drop in usage after the previous law was repealed.

Key finding

The statewide safety belt usage rate for all front seat occupants in Kentucky was 66.0 percent in 2004, with child restraint usage at 96.0 percent and motorcycle helmet usage at 58 percent.
