A Graduated Driver License (GDL) is a program designed to allow new drivers, typically teenagers, to develop their driving skills gradually and under lower-risk conditions. It typically consists of three stages: a learner's permit, an intermediate license, and a full license. The program includes restrictions such as nighttime driving and driving with other teens in the car, which are gradually lifted as the driver gains experience and demonstrates responsible driving behavior
. GDL systems have been shown to reduce teen crashes and deaths, with a 2015 meta-analysis indicating a 19% reduction in crashes associated with GDL laws
