Summary

This report addresses the persistent issue of high fatal crash rates among young drivers (ages 16–20) in Kentucky, despite the state’s adoption of a Graduated Driver Licensing (GDL) program. Although Kentucky implemented a simple GDL program in 1996 and expanded it in 2006 to include an intermediate licensing phase, supervised practice requirements, and passenger restrictions, the state continues to rank near the bottom nationally for teen driver fatalities per 10,000 licensed teen drivers. In 2019, young drivers accounted for 11.5% of fatal vehicle crashes nationally while comprising only 5.3% of licensed drivers. In Kentucky, this disparity was similarly pronounced, with 73 young driver fatalities recorded that year. The research aims to identify best practices from other jurisdictions to further strengthen Kentucky’s GDL program and improve roadway safety outcomes. The study employed a comprehensive literature review, an analysis of long-term GDL program performance at state and national levels, and a nationwide survey of state transportation agencies. Researchers examined Kentucky’s crash data from 2001 to 2020 to evaluate the impact of the 2006 GDL expansion, specifically looking at fatal and severe injury crashes involving 16- and 17-year-old drivers. The analysis also compared Kentucky’s GDL provisions against those of other states, focusing on core components such as minimum age requirements, holding periods, supervised driving hours, nighttime restrictions, and passenger limits. The survey of state agencies provided insights into how other jurisdictions structure their programs, verify practice hours, and conduct outreach activities. The findings indicate that the 2006 GDL expansion significantly improved safety for 16-year-old drivers, reducing fatal crashes by 65% and severe injury crashes by 69% compared to the 2001–2005 average. Similar reductions were observed for 17-year-old drivers. However, Kentucky’s overall teen driver fatality rate remains high relative to peer states like Massachusetts and Minnesota. The report identifies eight specific best practices to further enhance Kentucky’s program: (1) mandating or incentivizing parent driver education courses; (2) increasing the minimum age for an unrestricted license to 18; (3) starting nighttime driving restrictions at 10:00 pm instead of 12:00 am; (4) adjusting passenger restrictions to minimize distractions from peers under 20; (5) extending GDL coverage to drivers aged 18–21; (6) allowing mobile apps to log practice hours; (7) providing free novice driver decals; and (8) partnering with state police for visible enforcement. The significance of this report lies in its actionable recommendations for policy refinement. While Kentucky’s current GDL program has demonstrated effectiveness in reducing crashes among the youngest drivers, the state’s poor national ranking suggests that additional measures are necessary. By adopting these eight best practices, Kentucky can align its program more closely with national safety standards and potentially reduce the overrepresentation of young drivers in fatal crashes. The report underscores the importance of continuous evaluation and adaptation of GDL programs to address evolving safety challenges and improve outcomes for novice drivers.

Key finding

Kentucky's 2006 GDL program expansion led to substantial reductions in fatal and severe injury crashes for teen drivers, yet the state remains among the worst nationally for teen driver fatality rates, prompting recommendations for stricter licensing provisions and enforcement.
