Summary
This report evaluates the effectiveness of Kentucky’s 2006 “Buckle Up Kentucky: It’s the Law & It’s Enforced” seat belt safety campaign. The study was motivated by the state’s transition from secondary to primary enforcement of seat belt laws, allowing police to stop drivers solely for non-compliance. Despite legislative changes, Kentucky’s seat belt usage rates remained significantly lower than the national average, prompting the use of Selective Traffic Enforcement Programs (STEPs) to improve compliance and reduce crash fatalities. The 2006 campaign included a general initiative for all drivers and a targeted effort for pickup truck drivers, combining paid and earned media publicity with intensive law enforcement periods around Memorial Day. The evaluation methodology combined observational surveys, telephone surveys, enforcement data analysis, and crash statistics. Researchers conducted mini-surveys at 21 representative sites across the state to measure baseline and enforcement-phase seat belt usage. Pre- and post-campaign telephone surveys were administered to drivers, with an oversample of pickup truck owners, to assess awareness, perceived enforcement likelihood, and self-reported usage changes. Enforcement activities, including saturated patrols and checkpoints by state and local police, were documented alongside citation counts. Finally, fatal and injury crash data from the enforcement period were compared to averages from the previous three years. The results indicated limited success in increasing actual seat belt usage. Observational data showed a marginal increase in usage for all vehicles, rising from 67.3% at baseline to 67.9% during enforcement. Pickup truck usage increased slightly from 52.9% to 54.8%. This represented a diminishing return compared to previous years, with the usage increase dropping from 10.9% in 2003 to just 0.6% in 2006. However, telephone surveys revealed that the publicity was effective in raising awareness; statistically significant increases were observed in drivers’ knowledge of the primary enforcement law and their perceived likelihood of receiving a ticket. Enforcement was substantial, with 4,704 seat belt citations issued during the general campaign and 3,132 during the pickup-specific campaign. Crash data showed that while injuries and injury crashes were slightly lower than the three-year average, fatalities and total crashes were higher. The study concludes that publicity and warning citations alone are insufficient to substantially increase seat belt usage without effective enforcement of the primary law. The data suggest that while the public is aware of the law and supports primary enforcement, the perceived risk of being ticketed must be high enough to drive behavioral change. The authors emphasize that future efforts must combine robust enforcement with publicity that clearly communicates the likelihood of being stopped for a seat belt violation to achieve meaningful improvements in compliance.
Key finding
Safety belt usage increased from 67.3 percent to 67.9 percent for all vehicles and from 52.9 percent to 54.8 percent for pickups during the enforcement period, while fatal crashes and total crashes increased compared to the previous three years.
