Marijuana and Driving

“America made drunk driving a national issue and while there is no victory as long as a single American dies in an alcohol-related crash, a one-third reduction in alcohol use over just seven years shows how a focused effort and cooperation among the federal government, states and communities, law enforcement, safety advocates and industry can make an enormous difference,” said NHTSA Administrator Mark Rosekind. “At the same time, the latest Roadside Survey raises significant questions about drug use and highway safety. The rising prevalence of marijuana and other drugs is a challenge to everyone who is dedicated to saving lives and reducing crashes.”
