More than 500 law enforcement agencies statewide are on the prowl for drunk drivers, and the crackdown begins Friday.
The You Drink and Drive, You Lose Campaign is aimed at preventing traffic deaths during the July 4 holiday period.

During last year's campaign, there were 17 fatalities on Michigan roadways, two of which were alcohol-related.
