FILE - This Jan. 24, 2007 file photo shows a student going through parking cones at a driving school course in Tucker, Ga. Strong driver's license laws have led to fewer fatal crashes among 16-year-olds but with a disturbing side effect - more fatal accidents among 18-year-olds, a nationwide study found. Tougher licensing laws for student drivers has encouraged many teens to just wait until they turn 18 when the rules aren't so tough, but they hit the road with less experience.
