A first OWI in Michigan: what it can result in
Verified · next review
93 days — and 180 if the reading was high. Michigan’s high-BAC division is a separate offense with its own numbers rather than an add-on, and it nearly doubles both the maximum term and the fine. Community service of up to 360 hours can be part of the sentence, and the court may order vehicle immobilization even on a first conviction.
Written any number of ways — a 1st offense OWI, OWI 1st, OWI first offense MI, or a first OWI in MI — and the paperwork will use none of them. Michigan charges it under a section number, and that is what decides the range below.
Grade. Misdemeanor
Confinement. Up to 93 days, or up to 180 days at 0.17 or more
Fine. $100 to $500, or $200 to $700 at 0.17 or more

What turns this OWI into something worse
Each line below is a separate provision with its own punishment range. They stack with the arithmetic of prior convictions rather than replacing it.
| The fact | What it makes it | Detail and source |
|---|---|---|
| A reading of 0.17 or more | A separate high-BAC offense with its own maximums | Up to 180 days instead of 93, and a fine of $200 to $700 instead of $100 to $500. Michigan treats it as a distinct violation of subsection (1)(c) rather than as an aggravating factor applied to the ordinary one. Michigan Vehicle Code § 257.625 · Mich. Comp.

The device is a separate track
In Michigan the Secretary of State suspends the license on receiving the conviction record, and the interlock is part of the route back to driving. The restricted license and the conditions attached to it are decided through the Secretary of State’s hearing process rather than set as a flat term in the vehicle code.
In Michigan the interlock term runs Set at hearing and is administered by Michigan Secretary of State, through its hearing officers — which is why a plea that settles the criminal case does not settle the device. What counts as a violation on it, and what an agency adds to the term, is its own arithmetic: violations and lockouts. Getting it off at the end is a procedure of its own too — removal and waivers.

Michigan OWI questions
Is jail time mandatory for a 1st OWI in Michigan?
Michigan’s high-BAC division is a separate offense with its own numbers rather than an add-on, and it nearly doubles both the maximum term and the fine. Community service of up to 360 hours can be part of the sentence, and the court may order vehicle immobilization even on a first conviction.
How likely is jail time for a first OWI in MI?
Start from what the statute forces and what it leaves to the judge. The floor here is up to 93 days, or up to 180 days at 0.17 or more, and it moves on the facts: a reading of 0.17 or more means a separate high-bac offense with its own maximums. Everything above that floor is argued, and the same conviction can end up served in custody, on work release or as a condition of probation depending on the county and the judge. What no one can promise you is a sentence below the statutory minimum — that is not a question of persuasion.
