Interesting findings show that a 16 or 17 year old driver's risk of being killed in a crash increases when there are young passengers in the vehicle, compared to driving without any passengers. The older the driver, the lower the danger. The risk decreases by 62% when an adult age 35+ is in the vehicle.
