OWI First Offense in Michigan: Penalties, License Consequences, and Your Defense

Michigan calls it OWI — Operating While Intoxicated — not DUI. The terminology is different but the consequences are serious. Even a first offense carries potential jail time, a criminal record, and significant license sanctions that affect your ability to work and meet daily obligations. The decisions made in the weeks immediately following an arrest — including whether and when to request a license hearing — have lasting consequences.

First OWI Penalties Under Michigan Law

A standard first OWI conviction (BAC of .08-.16) under MCL 257.625 carries:

• Up to 93 days in jail (not mandatory for a first offense, but available to the court)
• Fines up to $500, plus costs and court assessments
• Up to 360 hours of community service
• License sanctions: 30-day hard suspension, then 150 days restricted driving
• Possible vehicle immobilization
• 6 points on your driving record

Michigan's "Super Drunk" Law: BAC of .17 or Higher

If your BAC was .17 or higher, Michigan's enhanced penalty statute (MCL 257.625(1)(c)) — commonly called the "Super Drunk" law — applies. Penalties increase significantly:

• Up to 180 days in jail
• Fines up to $700
• 45-day hard suspension followed by 320 days restricted with a mandatory BAIID (ignition interlock device)
• Possible vehicle immobilization

The Super Drunk law is frequently contested. Independent analysis of breath or blood test results, challenges to the calibration and maintenance records of the testing device, and questioning the accuracy of the original test are all avenues a defense attorney should evaluate.

Where Defenses Come From

An OWI charge is not automatically a conviction. Defenses exist at multiple stages of the case:

• The traffic stop — An officer must have reasonable, articulable suspicion to pull you over. A stop based on a hunch or without observable traffic violation can be challenged, and evidence obtained from an unlawful stop may be suppressed.
• Field sobriety tests — Standardized field sobriety tests (walk-and-turn, one-leg stand, horizontal gaze nystagmus) are subjective and affected by physical conditions unrelated to alcohol. Improper administration of these tests weakens their evidentiary value.
• Breathalyzer results — The DataMaster breathalyzer used in Michigan must be properly maintained, calibrated, and operated. Officers must follow specific protocols. Testing errors, equipment maintenance failures, and improper operator training are all legitimate challenges.
• Blood test results — Blood draws must follow a chain of custody and proper collection protocols. Lab handling and storage errors can call results into question.

Can a First OWI Be Expunged in Michigan?

As of 2021, Michigan law allows expungement of a first OWI offense after a 5-year waiting period from the date of sentencing, completion of probation, or release from custody — whichever is latest. Expungement removes the conviction from most public background checks and restores certain rights. However, the expunged offense remains visible to law enforcement and cannot be used to reduce the classification of any future OWI to a "first" offense.
