About the research
Abstract: This project evaluated the effectiveness of the Iowa Graduated Driver's Licensing (GDL) program in reducing crashes for teenage drivers during a four-year period before and after implementation of GDL. The report presents a review of the literature on teenage drivers, crash rates, and graduated driver's licensing programs around the country, followed by an analysis of teenage drivers and crash risk before and after implementation of GDL in Iowa.
