Risky teen driving

A researcher at the National Institutes of Health has managed to do something that's hard for even parents to do - check how teenagers really drive. Bruce Simons-Morton outfitted 42 family vehicles with devices that measured things like acceleration, braking, and swerving. He followed them for 18 months, and compared teens and parents on signs of risky driving:

"Teens engaged in a risky driving sort of style maintained on average a very high level of risky driving."  (8 seconds)

Simons-Morton says teens whose parents set limits tend to engage in less risky driving. So he says parents can limit things like night and highway driving, carrying passengers, and use of electronics.

The study was in the American Journal of Public Health.
