Too many teens in one car could be a deadly combination. That was the finding of a new study by AAA's foundation for Traffic Safety.
The study found a 16 or 17-year-old driver's risk of death in a car crash increases 44 percent when carrying a passenger younger than 21 and no older passengers.
That risk is double with two young passengers, and four times as great with three or more.
If an adult is in the car with a teen driver, risk of death in a car crash drops 62 percent, according to the study.
