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.
