Summary
This study investigates the characteristics of fatal crashes involving 16- and 17-year-old drivers in the United States, specifically focusing on the presence, age, sex, and number of passengers. Motivated by evidence that teenage passengers significantly increase crash risk for novice drivers, the research aims to document these patterns to inform Graduated Driver Licensing (GDL) policies and enforcement strategies. The authors analyzed data from the National Highway Traffic Safety Administration’s Fatality Analysis Reporting System (FARS) for crashes occurring between 2005 and 2010. Virginia data were excluded due to under-reporting of uninjured passengers. The study examined 9,578 fatal crashes involving 16- and 17-year-old drivers of passenger vehicles, tabulating variables such as driver demographics, passenger configurations, and risk factors including speeding, alcohol use, seatbelt non-use, and late-night driving. The results indicate that 57% of 16- and 17-year-old drivers involved in fatal crashes had at least one passenger. Among those with passengers, 73% carried only teenage passengers (aged 13–19). In crashes involving only teenage passengers, 56% had one passenger, 24% had two, and 20% had three or more. Passengers were predominantly of the same sex as the driver and within one year of the driver’s age. The prevalence of risk factors—including speeding, alcohol use, lack of a valid license, seatbelt non-use, and driver responsibility for the crash—was higher when teenage passengers were present compared to when the driver was alone. These risks generally increased with the number of teenage passengers. Conversely, the presence of an adult passenger aged 30 or older was associated with the lowest prevalence of these risk factors, suggesting a protective effect. While the total number of fatal crashes involving teen drivers decreased by 44% over the study period, the proportion of crashes involving teenage passengers remained constant at approximately 42–43%. The findings highlight that despite widespread GDL passenger restrictions, teenage passengers remain present in more than two of every five fatal crashes involving 16- and 17-year-old drivers. The study concludes that the "teens with teens" scenario remains a dominant fatal crash pattern. The data suggest that current GDL restrictions may not be fully effective or consistently enforced, as risky behaviors persist in the presence of peer passengers. The authors recommend that states use this data to refine GDL programs, enhance enforcement of existing laws, and encourage parental involvement to mitigate the elevated risks associated with teenage passengers. The presence of older adults appears to suppress risky driving behaviors, underscoring the value of supervised or adult-accompanied driving for novice teens.
Key finding
Among 16- and 17-year-old drivers in U.S. fatal crashes (2005-2010), 57% had passengers; crash risk factors (speeding, alcohol, late-night driving, seatbelt non-use, invalid licensing, crash responsibility) were more prevalent with teenage passengers—especially multiple teen passengers—and were lowest when an adult passenger aged 30+ was present.
