Between 1996 and 2015, vehicular fatalities per capita involving 16- to 20-year-old drivers declined by 47.4%. During this same period, states enacted licensure provisions in an á la carte fashion, now collectively referred to as graduated driver licensing (GDL) programs. While the literature demonstrates that ‘good’ GDL programs reduce teen licensing and fatalities, how these reductions occur remains open. In this study, individual GDL provisions and No-Pass-No-Drive laws are studied to understand reduction mechanisms. The evaluation is based on a state-by-year panel and uses difference-in-difference and triple difference specifications to identify causal impacts on rates of fatality, licensing, and fatalities per licensed driver. The empirical results consistently find that four of the seven GDL provisions and No-Pass-No-Drive laws impact 16- and 17-year-old drivers and all effects dissipate when provisions are no longer binding. Licensing provisions have little-to-no impact on fatalities per licensed driver.
