Ten states have enacted some form of graduated licensing programs for novice teen drivers. These policies phase in teenagers' driving rights as they become more skilled. Some states ban teens from driving at night until they become more experienced behind the wheel. Others require more practice time under adult supervision.

• More than 6,300 teens aged 15 to 20 died in auto accidents last year -- a figure that is expected to jump to 7,500 by 2012.

• Some 42 percent of teen driving deaths occur between 9 p.m. and 6 a.m.

• Some 66 percent of teens killed in crashes are passengers -- not drivers.

One year after Ontario passed a model graduated licensing law backed by the Insurance Institute for Highway Safety, there was a 66 percent drop in 16-year-olds' accident rates.
