Novice Teen Driving: GDL and Beyond
Research Foundations for Policy and Practice Symposium

Held on February 5-7, 2007 in Tucson, Arizona, the Symposium’s goal was to establish a vision for policy and practices to improve teen driving and current GDL systems. The Symposium was sponsored by the Centers for Disease Control and Prevention, GEICO Foundation, General Motors Corporation, National Highway Traffic Safety Administration, National Safety Council, Nationwide Insurance, United Parcel Service and State Farm Insurance.

These fact sheets summarize the current scientific findings on Graduated Driver Licensing that were presented at the Symposium in February. Information in the fact sheets is based on papers written by Symposium presenters and published in the April 2007 GDL Special Issue of the Journal of Safety Research.

The National Safety Council's second GDL forum since 2002, the February Symposium brought researchers and practitioners from around the world together to discuss updated research on teen driving performance and behaviors, effects of GDL laws on crash reduction, effects of parenting behaviors on teen driving safety, driver education, how GDL can be improved, and more. Symposium findings resulted in two classifications of effective GDL components:

  • GDL components proven to be effective: extended learner's permit holding periods, nighttime driving restrictions, and passenger restrictions.
  • GDL components that may be effective: supervised driving requirements, cell phone restrictions, seat belt use requirements, and contingent advancement.

There are several things you can do to increase effectiveness of GDL in your state:

  • Implement interventions that support longer learner's permit holding periods and restrictions on nighttime driving, and the number and age of passengers that new drivers can carry.
  • Continue to educate the public about your state's requirements on extended learner's permit holding periods, nighttime driving restrictions, and passenger restrictions. Parents especially need to be aware of major risks to teen drivers and existing laws, and parental education programs are encouraged.

Experts report progress in reducing teen driver crashes but maintain states, parents can do more

Fatal crashes involving 16 year old drivers in 2005 were at their lowest level since 1992, despite the highest national population of 16 year olds (4.2 million) since 1977, according to researchers gathered at a National Safety Council symposium on teen driving. These reductions are due in large measure to implementation of Graduated Driver Licensing (GDL) systems in many states, researchers said. Learn more...

'Chicago Tribune' recognized for teen driver series
