WASHINGTON (Oct. 20, 2014) – Experience behind the wheel may matter more than age when it comes to the safety of young-adult drivers, according to two new studies by the AAA Foundation for Traffic Safety. These results suggest that states could reduce road crashes, fatalities and injuries by extending graduated driver licensing (GDL) laws to novice drivers beyond age 17. AAA is promoting this research as part of National Teen Driver Safety Week, which takes place from Oct. 19-25.
Graduated driver licensing laws are designed to help new drivers gain practical experience in a relatively safe environment by initially restricting their exposure to risky situations, such as driving at night or with young passengers. The law then gradually phases in more privileges as new drivers gain more experience.
“Turning 18 does not instantly make someone a safer driver,” said Peter Kissinger, President and CEO of the AAA Foundation for Traffic Safety. “This new research clearly demonstrates how important experience is to safe driving and suggests that graduated driver licensing laws may be beneficial for people that begin driving at an older age.”
The findings are based on two studies that examined crash rates of new drivers. The first study looked at crash rates in both California and North Carolina, which are two states that allow driving at age 16 and have no GDL requirements for new drivers ages 18 or older. While new drivers licensed at older ages tended to be less likely to crash during their first months and years of driving than younger beginners, the research revealed an important exception: new drivers licensed at age 18 were more likely to be involved in a crash resulting in injuries during their first year of solo driving than new drivers licensed at any other age.
The second study examined crash rates in New Jersey, which has a minimum age of 17 for unsupervised driving and is the only state in the country to have a comprehensive GDL program for all new drivers up to age 21. In New Jersey, while crash rates of new drivers licensed at different ages largely converged after six months of solo driving experience, older beginners had lower crash rates overall and lower rates of injury crashes than younger beginners.
Although the data did not allow researchers to directly investigate whether these differences were caused by GDL provisions, collectively, the results of the two studies suggest that applying GDL to all new drivers, or at least to some new drivers older than 17, might have a protective effect and improve safety.
“Graduated driver licensing can greatly reduce crashes, injuries and deaths for everyone on the road,” said Jennifer Ryan, AAA director of state relations. “These laws set the parameters to help ease the transition behind the wheel during the learning to drive process.”
Graduated driver licensing programs have reduced 16- and 17-year-old driver crashes, but generally do not apply to new drivers ages 18 and older. Prior AAA Foundation research found that an estimated 36 percent of new drivers miss out on the protections of GDL by delaying licensure until age 18 or older. AAA is not calling for states to extend GDL provisions just yet, but does believe the research results are very promising in terms of pinpointing a way to keep these drivers safe. The AAA Foundation is planning to dive deeper into this area of research in the coming year.
Motor vehicle crashes are the leading cause of death for U.S. teenagers, and drivers ages 18-20 were involved in more than 800,000 crashes in the United States in 2012.

Established by AAA in 1947, the AAA Foundation for Traffic Safety is a 501(c)(3) not-for-profit, publicly-supported charitable educational and research organization. Dedicated to saving lives and reducing injuries on our roads, the Foundation’s mission is to prevent crashes and save lives through research and education about traffic safety. The Foundation has funded over 200 research projects designed to discover the causes of traffic crashes, prevent them and minimize injuries when they do occur.

As North America’s largest motoring and leisure travel organization, AAA provides more than 54 million members with travel, insurance, financial and automotive-related services. Since its founding in 1902, the not-for-profit, fully tax-paying AAA has been a leader and advocate for the safety and security of all travelers. AAA clubs can be visited on the Internet at AAA.com.
