Panel Paper:
Graduated Driver Licensing Laws, Teen Licensure, and Vehicular Fatalities
*Names in bold indicate Presenter
The empirical results indicate that only half of the GDL provisions have any impact on vehicular fatalities and licensure. Specifically, a minimum intermediate licensing age of 16.5 or older reduces vehicular fatalities and licensure by 14.0% and 34.9%, by far the largest impact. Nighttime driving restriction reduces licensure by 9.4%, but no effect on fatalities. Teen cellphone/texting bans reduce licensure by 9.4% and fatalities by 6.8%. Mandating supervised driving hours has no effect on licensure, but increases fatalities by 6.9%. All impacts dissipate as teens age and have small, negligible effects beyond age 17. Lastly, GDL provision have small impacts on fatalities per licensed driver for those 16-17, suggesting weak programmatic effect and strong incapacitation effects
