Facts about travel risk
…the risk of death for an 18-year-old male driver is about the same as that for an 80-year-old female driver, but both are safer than the operator of a motorcycle. And counterintuitively, risk is higher in the mountains in summer than in winter…the risk of death for vehicle occupants who are 16 to 20 years old, on weekdays, is 13.86 per 100 million trips between 8 a.m. and noon. But between 8 p.m. and midnight it is 30.51 per 100 million trips, more than twice as high.
