More results showing that having a number of teenagers in the car is not good for safety. AAA has announced the results of a study, saying 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, highlighting the protective influence that parents and other adults have in the car.
