There are fewer drunk drivers on the road, but their place has been taken by people high on marijuana and prescription drugs, according to two reports from the National Highway Traffic Safety Administration.
The number of inebriated drivers has declined by almost a third since 2007, but in a 2014 survey nearly 1 in 4 on the road tested positive for a drug that endangered them or others, NHTSA said.
“The latest roadside survey raises significant questions about drug use and highway safety,” NHTSA Administrator Mark Rosekind said. “The rising prevalence of marijuana and other drugs is a challenge to everyone who is dedicated to saving lives and reducing crashes.”
