Graduated Driver Licensing is a proven method of reducing teen drivers’ crash risk by 20-40 percent, and GDL works by maximizing experience while minimizing common risks teens face on the roads such as nighttime driving and carrying teen passengers. This allows new drivers to gain experience without exposure to high-risk scenarios.
All 50 states and D.C. have implemented some form of GDL. Typically, GDL has three stages:
1. Learner’s permit - teen drivers only can drive with supervision
2. Intermediate licensure - teens may drive unsupervised but with restrictions such as passenger and nighttime driving
3. Full, unrestricted licensure
The seven recommended GDL elements are based on decades of scientific research
Additionally safety belts always should be worn, states should completely ban the use of cell phones while driving and should have a zero-tolerance policy for drug or alcohol use.
