Investigate (1) whether crash rates for young drivers who delay licensure beyond ages covered by GDL restrictions differ from crash rates for young drivers who obtain driver licenses under GDL and (2) factors that may contribute to any differences. Produce generalizable results not limited to specific states using data sources and analysis methods that incorporate sufficient variation in geography, socioeconomics, GDL laws, and state driver education policies. Utilize multiple data sources, including the Fatality Analysis Reporting System, state-level data, and other sources of quantitative or qualitative data. Consider the impacts of any state-level driver education requirements for drivers age 18 or older. Develop resources to support implementation of the research results by state driver licensing agencies and SHSOs.
