Montgomery, Alabama State troopers say they're planning extra patrols during the Labor Day holiday to find drivers who shouldn't be on the road.
Public safety officials say the "Drive Sober or Get Pulled Over" campaign will last through midnight Monday. It began Friday night.
Troopers say six people died in traffic accidents last Labor Day weekend in Alabama, and alcohol was a factor in at least three of those cases.
Authorities say none of the people killed in cars was wearing a seatbelt.
