Driving collisions are the leading cause of death among adolescents, accounting for 15 teenage deaths per day in the United States. (National Highway Traffic Safety Administration 2003). Driving fatalities are significantly more likely to occur when distracting teenage passengers are in the automobile(Insurance Institute for Highway Safety 2000). Fatalities are also more likely to occur in the evenings, on the weekends, and during the summer months (National Center for Statistics and Analysis 2005).
