STERLING HEIGHTS, Mich. (AP) — Stepped-up patrols targeting drunken drivers are taking place in Michigan around the Fourth of July holiday.

The Michigan Office of Highway Safety Planning says the patrols start on Wednesday. An event to publicize the effort is planned at AMC Forum 30 in Sterling Heights.

A movie-themed effort highlighting the importance of designated drivers is called “Who’s Your D.D.?” and features posters and life-sized action figures.

Law enforcement officers from police departments, sheriff’s offices and the Michigan State Police will conduct increased drunken driving enforcement in all 83 Michigan counties during the Fourth of July drunken driving crackdown, which runs through July 12.

During last year’s Fourth of July crackdown, the state says 236 motorists were arrested for drunken driving as a result of extra patrols.
