Summary
This research brief by the AAA Foundation for Traffic Safety addresses the broader impact of crashes involving teen drivers (ages 16–19) on all road users, not just the drivers themselves. While fatalities among young drivers declined by nearly 40% between 2007 and 2016, teens remain overrepresented in motor vehicle crashes. The study aims to update previous findings by assessing fatality rates for motorists and non-motorists involved in these crashes, stratified by specific risk factors such as speeding, nighttime driving, and passenger presence. The study utilized 2016 data from the National Highway Traffic Safety Administration’s Fatality Analysis Reporting System (FARS) and the Crash Report Sampling System (CRSS). FARS provided data on all fatal crashes on public roadways, while CRSS offered a nationally representative sample of all police-reported crashes. The researchers estimated the total number of crashes involving teen drivers and calculated fatality rates per 10,000 individuals involved. These rates were analyzed across different road user types—teen drivers, passengers, occupants of other vehicles, and non-motorists (pedestrians and cyclists)—and further stratified by risk factors including driver age (16–17 vs. 18–19), passenger demographics, speeding, time of day, and season. In 2016, teen drivers were involved in approximately 1.05 million crashes involving nearly 2.86 million individuals, resulting in 3,270 fatalities. The overall fatality rate was 11.4 per 10,000 individuals involved. Non-motorists faced the highest risk, with a fatality rate of 443.6 per 10,000, compared to 10.5 for teen drivers, 15.5 for passengers, and 7.7 for occupants of other vehicles. Risk factors significantly influenced these rates. Speeding increased the overall fatality rate fourfold (34.8 vs. 8.5 per 10,000), with non-motorists in speeding-related crashes facing a rate of 3,097.3 per 10,000, meaning nearly 30% of non-motorists in such crashes died. Nighttime driving (9 p.m.–5 a.m.) increased the overall fatality rate by 3.8 times. Carrying only teen passengers increased the fatality rate by 51% compared to driving alone, whereas carrying a passenger aged 35 or older reduced the overall fatality rate by 8%. The findings underscore that teen driver crashes pose a significant risk to all road users, particularly vulnerable non-motorists. Speeding and nighttime driving were identified as major risk factors that drastically increase fatality rates for everyone involved. The presence of teen passengers also elevates risk, while older passengers appear to mitigate it. These results highlight the need for targeted education and interventions to address these specific risk factors, emphasizing that the consequences of teen driving errors extend beyond the driver to the broader community.
Key finding
Nonmotorists experienced the highest fatality rates in teen driver crashes, and these risks were dramatically amplified when the teen driver was speeding or driving at night.
