(AREA) -- Law enforcement agencies in more than two dozen Michigan counties are conducting extra patrols to arrest suspected drunken drivers through April 8. The Michigan Office of Highway Safety Planning is coordinating the effort. The enforcement period includes the NCAA men's and women's basketball tournaments, and high school and college spring breaks. In 2012, 2,488 people were arrested for drunk driving during the NCAA tournament time period. Of those, 789 were arrested under the state's high blood-alcohol content law with BAC's of .17 or higher. More than 400 of those arrests were made by grant-funded law enforcement agencies during last year's drunk driving crackdown. Locally, St. Clair County received federal funding for the extra patrols through April 8.
