Michigan DUI laws use the term Operating While Intoxicated, or OWI, rather than DUI. A driver age 21 or older is generally considered intoxicated at a blood alcohol content of 0.08% or higher, while a BAC of 0.17% or higher triggers Michigan’s enhanced High BAC charge, sometimes called the Super Drunk law. Drivers under 21 face a Zero Tolerance standard with any measurable alcohol content. This guide covers penalties, license sanctions, implied consent, and expungement under Michigan Compiled Laws Section 257.625.
What Michigan Law Calls a DUI
Michigan statutes do not use the word DUI. Michigan Compiled Laws Section 257.625 instead defines two separate charges. Operating While Intoxicated, or OWI, generally applies when a driver has a BAC of 0.08% or higher or is under the influence of alcohol or a controlled substance. Operating While Visibly Impaired, or OWVI, generally applies when a driver’s ability to operate a vehicle is visibly impaired, even without a specific BAC reaching the 0.08% threshold.
The law also generally recognizes a separate High BAC charge, often called Super Drunk, which applies when a driver’s BAC measures 0.17% or higher. This tier generally carries harsher penalties than a standard OWI. A separate Zero Tolerance provision generally applies to drivers under 21, who may face a charge with any measurable bodily alcohol content rather than the 0.08% threshold used for adult drivers.
How Michigan Defines Operating a Vehicle
Michigan courts have generally interpreted the word operating under Michigan Compiled Laws Section 257.625 to include more than active driving. A person may generally be considered to be operating a vehicle if they are in actual physical control of it, even if the vehicle is parked or not moving. This interpretation comes from Michigan case law, including People v Hyde, 285 Mich App 428, which helped establish the elements courts generally require to prove an OWI charge.
Michigan courts have also generally addressed where an OWI charge can apply. In People v Rea, 500 Mich 422, the Michigan Supreme Court generally interpreted the phrase generally accessible to motor vehicles under the statute, which can extend an OWI charge beyond public roads to parking areas and similar locations. In People v Lyon, 310 Mich App 515, a Michigan appeals court generally held that the term vehicle under the statute can extend to devices such as motorized scooters.
Penalties for a First Offense OWI
A first offense OWI in Michigan is generally treated as a misdemeanor under Michigan Compiled Laws Section 257.625. The statute generally distinguishes a standard first offense from a High BAC first offense, with the High BAC tier generally carrying a longer potential jail term and a higher potential fine range than a standard OWI. A first offense OWVI conviction is generally treated as a lesser misdemeanor with its own separate fine range under the statute.
The exact number of jail days, the specific fine amounts, and community service requirements for a first offense are set out within Michigan Compiled Laws Section 257.625 and its related subsections. A court may also generally order vehicle immobilization as part of a first offense sentence. Because these figures depend on the specific subsection a person is charged under, readers should generally confirm the current statutory language rather than relying on a single number.
Penalties for a Second Offense OWI
A second OWI offense is generally treated as an enhanced misdemeanor when a prior qualifying conviction occurred within a set lookback period. Michigan Compiled Laws Section 257.625 generally structures this enhancement around a prior offense that occurred within seven years, sometimes summarized as the two within seven rule. A second offense generally carries a higher potential fine range, mandatory minimum jail time or community service, and generally more severe license consequences than a first offense.
This seven year lookback period is specific to the second offense enhancement. It is a common misconception that this same seven year window applies to every repeat OWI charge in Michigan, but the statute generally treats a third offense differently, as explained in the next section.
Third Offense OWI as a Felony
A third OWI offense in Michigan is generally treated as a felony under Michigan Compiled Laws Section 257.625, regardless of how long ago the first two offenses occurred. This lifetime lookback approach is often referred to informally as Heidi’s Law. A third offense generally exposes a person to potential prison time under a statutory range, a higher potential fine range than misdemeanor level offenses, and an extended license revocation period discussed later in this guide.
The distinction between the second offense and third offense lookback rules is a frequent source of confusion. A second offense generally counts only if the prior offense falls within seven years. A third offense generally counts no matter how many years have passed since the first two convictions, which is the defining feature of the lifetime lookback under Heidi’s Law.
OWI Causing Injury or Death
Michigan Compiled Laws Section 257.625 generally treats an OWI that causes a serious injury or death as a more serious felony than a standard third offense structure. Courts have generally examined this category closely, including in People v Miller, 498 Mich 13, which generally addressed double jeopardy limits on convicting a person of both a standard OWI and an OWI causing injury for the same driving incident. This category generally carries the most severe potential penalties within Michigan’s OWI framework.
Because cases involving injury or death generally involve more complex legal and evidentiary issues than standard OWI charges, general guides cannot substitute for individualized legal guidance in this category. A person facing this type of charge should generally consult a licensed attorney rather than relying on general penalty ranges described for other offense tiers.
License Suspension Versus Revocation
Michigan generally handles license consequences through two separate systems. A criminal court generally issues the penalties described above, while the Michigan Department of State generally issues administrative license sanctions under Michigan Secretary of State license restoration information that operate independently of the criminal case outcome. A person can generally be affected by both processes even if one case resolves favorably.
Suspension and revocation are often used interchangeably but generally describe different administrative outcomes. A suspension generally refers to a temporary loss of driving privileges for a defined period after which driving may generally resume. A revocation generally refers to a more serious action under Michigan Compiled Laws Section 257.303 that generally requires a formal hearing before driving privileges can be restored, rather than an automatic reinstatement date tied to a calendar.
Implied Consent and Chemical Test Refusal
Michigan Compiled Laws Section 257.625c generally establishes an implied consent framework, meaning a person who holds a Michigan license and drives on public roads is generally considered to have already agreed to a chemical test of breath, blood, or urine if lawfully arrested for an OWI related offense. This consent is generally considered part of holding a Michigan license rather than something a driver separately agrees to at the time of arrest.
A refusal to submit to a properly requested chemical test generally triggers a separate administrative license suspension under Michigan Compiled Laws Section 257.625f, independent of the underlying criminal OWI case. Refusal does not generally prevent OWI prosecution from proceeding. A driver who wishes to challenge a refusal based suspension generally must request an administrative hearing within a short window after the refusal is reported to the Michigan Department of State.
Restricted Licenses and Ignition Interlock
Depending on the offense tier, Michigan law generally allows a restricted license once part of a suspension or revocation period has been served. This restricted license is often generally conditioned on installing an approved ignition interlock device on any vehicle the person operates. The device generally requires a breath sample before the vehicle will start and may generally require additional samples while the vehicle is being driven.
Michigan Compiled Laws Section 600.1084 generally governs specialty court interlock programs connected to sobriety court participation, discussed further in the next section. A violation of interlock program rules can generally affect a person’s restricted license status and may generally extend the underlying suspension or revocation period already in place.
Sobriety Court Programs
Some Michigan jurisdictions generally offer sobriety court or DWI court programs under Michigan Compiled Laws Section 600.1084. These programs are generally treatment focused alternatives available to certain eligible offenders at a court’s discretion rather than as an automatic option in every case. Participation generally involves supervision, testing, and treatment components tied to the ignition interlock requirements described above.
Eligibility for a sobriety court program is generally determined on a case by case basis rather than being uniformly available across every Michigan county. A person interested in this option should generally raise the question within their own criminal case rather than assuming statewide availability based on general information.
First Offense Expungement Under Clean Slate
Michigan law generally allows a first offense OWI related conviction to be set aside from a person’s criminal record under legislation signed in 2021, with eligibility rules confirmed effective February 19, 2022 by the Michigan Attorney General’s office. This option is generally available only once in a person’s lifetime and generally requires a waiting period of five years following the end of probation, sentencing, or parole, whichever occurs last, according to the Governor Whitmer’s official announcement on Michigan’s Clean Slate OWI expungement law.
This expungement generally requires a formal petition reviewed by a judge under Michigan Attorney General guidance on first-time OWI expungement rather than happening automatically after the waiting period passes. The law generally excludes any case where the underlying offense caused injury or death to another person. Expungement generally removes the conviction from a person’s criminal record, though the underlying driving record maintained separately by the state may not be affected in the same way.
Common Misconceptions About Michigan OWI Law
A common misconception is that refusing a chemical test avoids an OWI conviction. Refusal generally does not prevent prosecution under Michigan Compiled Laws Section 257.625c and generally adds a separate administrative suspension on top of any criminal case outcome. Another common misconception is that an OWI charge only applies while a vehicle is actively moving, when Michigan courts have generally interpreted operating to include being in physical control of a parked, running vehicle.
A third misconception is that expungement of a first offense OWI happens automatically once five years pass. Michigan law generally requires an affirmative petition and judicial review rather than an automatic removal, and this option is generally unavailable for a second or third offense or for any case involving injury or death. Readers can review the current statutory language directly in Michigan Compiled Laws Section 257.625 (OWI statute).
Laws and enforcement may change, so readers should verify current penalties and license rules with official Michigan state sources before relying on any general summary. General guides like this one are meant to explain how Michigan’s OWI framework generally works rather than to predict an outcome in any specific case, and additional context on how this content is intended to be used appears in the Disclaimer below.
