Teen Driver Fatality Risk Quadruples with Multiple Young Passengers IN VEHICLE
(LOS ANGELES, May 8, 2012) – The AAA Foundation for Traffic Safety today released a study showing a strong association between the number and age of passengers present in-vehicle and the risk of a teen driver dying in a traffic crash.
The report, “Teen Driver Risk in Relation to Age and Number of Passengers,” found that the likelihood of a 16- or 17-year-old driver being killed in a crash, per mile driven, increases with each additional young passenger in the vehicle. Compared to driving with no passengers, a 16- or 17-year-old driver’s fatality risk:
  • Increases 44 percent when carrying one passenger younger than 21 (and no older passengers)
  • Doubles when carrying two passengers younger than 21 (and no older passengers)
  • Quadruples when carrying three or more passengers younger than 21 (and no older passengers)
Conversely, carrying at least one passenger aged 35 or older cuts a teen driver’s risk of death by 62 percent, and risk of involvement in any police-reported crash by 46 percent, these findings highlight the protective influence that parents and other adults have in the car.
In California, 445 drivers aged 16 and 17 were involved in fatal crashes during the years 2006-2010.  Nearly half of those crashes (48%) involved teen drivers crashing while carrying passengers in the vehicle under the age of 21.
The study analyzed data on crashes and the number of miles driven by 16- and 17-year-olds to assess the effect on a teen driver’s safety of having passengers in the vehicle. Though widely accepted that passengers increase a teen driver’s risk of being in a crash, recent licensing restrictions – particularly adoption by most states of passenger restrictions for novice teen drivers, and a substantial overall decline in teen traffic fatalities – beg the question of just how significant the risk is.
Despite recent progress, the new report confirms that carrying young passengers (under 21) is still a major risk factor for 16- and 17-year-old drivers.
“We know that carrying young passengers is a huge risk, but it’s also a preventable one,” said AAA Foundation for Traffic Safety President and CEO Peter Kissinger. “These findings should
send a clear message to families that parents can make their teens safer immediately by refusing
to allow them to get in the car with other young people, whether they’re behind the wheel or in the passenger seat.”
“The connection between carrying young passengers and increased fatal crash risk is clear, and placing appropriate limits is a key part of Graduated Driver Licensing (GDL) in California,” said Anita Lorz Villagrana, the Automobile Club of Southern California’s manager of community affairs & traffic safety. “By limiting the number of passengers that 16- and 17-year-old drivers can have in the car, California’s GDL with its strong passenger restriction help ensure that teens stay focused on the road and gain the experience they need to become safe drivers. It’s critical, too, that parents enforce the law and family rules that restrict passengers and help keep their teens safe.”
Additionally, given the significant decrease in risk seen when adults 35 and older were present, parents and guardians can also help protect novice teen drivers by spending more time in the car with them.
“The Auto Club and AAA Foundation are dedicated to reducing fatalities on our roadways, and want to get the message out to further reduce the risk of a crash or fatality among the riskiest drivers on the road,” said Lorz Villagrana.  “Parents and teens can reduce this risk today.”
The Auto Club and AAA Foundation urge families to consider these steps:
  • Know the graduated driver licensing system for your state and consider your teen driver’s skill and abilities in regards to passengers as long as they feel it necessary.
  • Sign a parent-teen driving agreement that stipulates teens will not ride as passengers of teen drivers without a parent’s advance permission
  • Provide transportation alternatives for teens who honor that pledge
  • Talk with other parents so they know the rules for your teen and will help enforce them
  • Spend time as a passenger when your teen is at the wheel.  Your presence and your guidance help make your teen a safer driver
  • Visit for resources that can help teens become safer drivers, including a parent-teen driving agreement covering safety risks like passengers, cell-phone use and night driving
The Auto Club and the AAA Foundation for Traffic Safety have long-standing commitments to improving teen driver safety through research and the development of science-based tools and resources.
