The Michigan Office of Highway Safety Planning said more than 60 agencies in 15 counties will be conducting extra patrols that began Thursday and end Oct. 31. The patrols are supported by federal traffic safety funds.
Agencies participating in the effort are in Ottawa, Allegan, Calhoun, Berrien, Chippewa, Genesee, Ingham, Jackson, Kent, Macomb, Marquette, Monroe, St. Clair, Washtenaw and Wayne counties.
Last year, officers reported arresting 261 drunken drivers the weekend before Halloween.
