Tennessee’s Graduated Driver License (GDL) Program is a multi-tiered program designed to ease young novice drivers into full driving privileges as they become more mature and develop their driving skills. By requiring more supervised practice, the State of Tennessee hopes to save lives and prevent tragic injuries. Tennessee’s GDL Program started on July 1, 2001. It places certain restrictions on teens under the age of 18 who have learner permits and driver licenses. The program requires parent/legal guardian involvement, and emphasizes the importance of a good driving record.
