The OWI Law in Michigan
In Michigan the offense is OWI, and the limit is 0.08.
Driving in Michigan is consent to a breath or blood test when an officer has cause to suspect OWI; the license case that follows a refusal or a failed test is run by the Secretary of State, separately from the criminal case.
For charging and sentencing, Michigan counts prior offenses within 7 years for a second offense; a third is a felony with no time limit.
Who Makes OWI Arrests in Ludington
The Mason County Sheriff's Office and the agency that reports for Ludington (filed by the FBI as Ludington Police Department) make the OWI arrests in and around Ludington.
The FBI's agency list also places one more agency in Mason County: the Mason County State Police (state police); the Mason County State Police makes the arrests on the state highways.
Together, the two agencies in Mason County with all twelve months of 2025 on file reported 781 arrests to the FBI that year, all offenses together; the FBI's count for Mason County does not break OWI out.
