As of 2005, all 50 states have some sort of Graduated Drivers License law. However, GDL laws in many states are missing key components. The AAA Foundation recommends that all GDL laws have three stages with some combination of the following:
- Six- to 12-month learner’s permit with at least 50 hours of supervised driving.
- Six- to 12-month intermediate or probationary license with meaningful night and passenger restrictions:
- States should examine their own crash data to determine the starting time for night restrictions. At a minimum, probationary license holders should be restricted from driving from midnight to 5 a.m.
- All GDL laws should include meaningful passenger restrictions. At a minimum, teens should be prohibited from transporting other teen passengers for at least six months in the intermediate/probationary license stage.
