The presence of passengers in a vehicle has been shown to increase the risk of fatal crash involvement for teenage drivers; however, the studies that have quantified this relationship were based on data that are now over a decade old. In the years since these studies, most U.S. states have enacted graduated driver licensing systems that limit the number of passengers that young drivers are allowed to carry during their first several months of independent driving, and the number of 16- and 17-year-old drivers involved in fatal crashes each year has decreased by more than half. The objective of this study was to provide updated estimates of the relationship between the number and ages of passengers present and the crash risk per mile driven of 16- and 17-year-old drivers.
