Motor vehicle crashes are the leading cause of death for teenagers, resulting in thousands of deaths nationwide per year. In fact, teenagers are involved in three times as many fatal crashes as other drivers, according to the National Highway Traffic Safety Administration.

For Judy Appleby and Bob Moore, these are more than statistics. Each lost their teen in crashes. However, many experts believe accidents like the ones that took the lives of Michael Appleby and Cassie Moore can be prevented if parents and teenagers sit down together to learn and practice safe-driving techniques.

Experts say teenagers are more prone to accidents because of their inexperience behind the wheel, their risk-taking behavior and immaturity.

To keep teen drivers safe on the road, Carfax -- a company that can check the history of any used car - is launching the Safe Car-Safe Teen Driver Campaign.

It features an interactive Web site designed to make parents and teens aware of risks and safety measures for young drivers to help reduce the number of teenagers involved in fatal or disabling automobile crashes.

Another component of the program is an e-mail drive designed to reach the millions of parents who have or will have teens at the driving age in their household.
