Research has shown that factors that help to keep teens safe include parental involvement, minimum legal drinking age and zero tolerance laws, and graduated driver licensing systems. These proven steps can protect the lives of more young drivers and everyone who shares the road with them.

*High school students aged 16 years and older who, when surveyed, said they had driven a vehicle one or more times during the past 30 days when they had been drinking alcohol.
