The OWI Law in Michigan
Drunk driving is charged as OWI in Michigan, at a blood alcohol level of 0.08 or more.
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 Isabella County
The Isabella County Sheriff's Office and the agencies that report for Mount Pleasant and Shepherd make the OWI arrests in Isabella County.

The Records an OWI Leaves
