A Meta-Analysis of Graduated Driver Licensing Laws

Extensive research has documented the benefits of Graduated Driver Licensing (GDL programs in reducing teen novice driver crash rates. However, the contribution of the individual components (e.g. nighttime driving restrictions, teenage passenger restrictions, minimum holding periods, etc.) of typical GDL programs is less well understood. In part, this is a result of States passing multi-component laws that make isolating the effects of the individual components difficult. In this study, the Naitonal Highway Traffic Safety Administration will conduct a meta-analysis of Graduated Driver Licensing (GDL) research in an attempt to gain a better idea of the relative benefit of the various individual components typically found in GDL programs
