Statistics

Comprehensive Graduated Driver Licensing (GDL)

General Statistics

States with comprehensive GDL programs in place report as much as a 40 percent drop in the number of fatal crashes among 16-year-old drivers.¹
Although three components of GDL separately contribute to reduced crash rates (extended learner permit period, nighttime driving restrictions, and passenger restrictions) , GDL programs that combine all three may result in the highest crash reductions among 16-year-old drivers.²^,3
Nearly all states have some components of GDL law in place to help protect teens from serious accidents during the first several months of driving.
