A first OWI conviction in Michigan carries mandatory penalties, but the outcome depends heavily on your blood alcohol content, whether you refused a breath test, and how you handle the legal process

Operating While Intoxicated (OWI) is Michigan's term for drunk driving. A first offense is a misdemeanor, not a felony, but it still results in a criminal record, fines, possible jail time, and driver's license suspension. The exact penalties vary based on your BAC (blood alcohol content) at the time of arrest and whether you refused a chemical test. Understanding what Michigan law requires — and what happens at each stage — helps you know what to expect and what decisions matter most.

This guide covers the legal consequences, the court process, and the practical steps you will face. It does not replace talking to a Michigan criminal defense attorney, who can review the specific facts of your case and advise you on your options.

Key Takeaways

  • A first OWI in Michigan is a misdemeanor with mandatory minimum penalties: fines between $250 and $500, up to 93 days in jail, and automatic driver's license suspension for at least 6 months.
  • Your BAC level at arrest determines which tier of penalties you face: under 0.08% (still illegal), 0.08% to 0.16%, or 0.17% and above each carry different fines and jail exposure.
  • Refusing a breath or blood test triggers an additional administrative license suspension separate from any court-ordered suspension, and the refusal itself can be used against you in court.
  • The court process typically includes an arraignment, possible plea negotiations, and either a trial or guilty plea; most first-time cases resolve without trial.
  • After conviction, you must complete a substance abuse assessment and any recommended treatment before your license can be restored, even partially.

Mandatory Penalties for a First OWI Conviction

Michigan law sets minimum and maximum penalties for a first OWI based on your BAC at the time of arrest. These are not suggestions — the court must impose at least the minimum, though it can impose more.

If your BAC was under 0.08% (but you were still arrested for impaired driving), the minimum fine is $250 and the maximum is $500. You can face up to 93 days in jail. If your BAC was 0.08% to 0.16%, the minimum fine rises to $500 and the maximum to $1,000, with up to 6 months in jail possible. If your BAC was 0.17% or higher, the minimum fine is $500, the maximum is $1,000, and you face up to 6 months in jail. In all three tiers, your driver's license is suspended for at least 6 months.

These are criminal penalties imposed by the court after conviction. They are separate from the administrative license suspension that begins when ready after arrest if you failed or refused a chemical test.

Driver's License Suspension and Restoration

Your license suspension happens in two parts: administrative suspension and court-ordered suspension. Both must expire before you can drive legally again.

If you took a breath or blood test and failed it (BAC 0.08% or higher), the Michigan Secretary of State automatically suspends your license for 6 months starting from the date of arrest. If you refused the test, the suspension is 1 year. This suspension is administrative — it happens whether you are convicted or not. You receive a notice in the mail; you do not have to wait for a court hearing.

The court then imposes its own suspension at sentencing, which is at least 6 months for a first offense. The two suspensions run at the same time, not one after the other. After both expire, you can request a license restoration, but you must first complete a substance abuse assessment through a Michigan-approved provider and follow any treatment recommendations. Without proof of completion, the Secretary of State will not restore your license. You may be able to request a restricted license (for work, school, or treatment) before the full suspension ends, but this requires a court petition and proof that you have started the assessment process.

The Role of Your BAC and Chemical Test Refusal

Your blood alcohol content at arrest determines which penalty tier applies, but it also affects how the prosecution builds its case and what defenses may be available. A BAC of 0.08% or higher is considered per se intoxication in Michigan — meaning the state does not have to prove you were impaired; the number alone is enough. A BAC under 0.08% requires the prosecution to prove impairment through other evidence: officer observations, field sobriety tests, dashcam video, or witness statements.

If you refused a breath or blood test, you face an additional 1-year administrative license suspension instead of 6 months. However, the refusal itself is admissible in court and can be used to suggest consciousness of guilt. Many people believe refusing protects them, but in Michigan it typically makes the case harder, not easier. A criminal defense attorney can advise whether the test was lawfully requested and whether challenging it makes sense in your specific situation.

What Happens in Court: Arraignment Through Sentencing

Your first court appearance is the arraignment, usually held within 72 hours of arrest. At arraignment, you are told the charges, informed of your rights, and the court decides whether to set bail or release you on your own recognizance. You will also be advised of your right to an attorney; if you cannot afford one, you can request a public defender. This is not the time to plead guilty or not guilty — that comes later.

After arraignment, your attorney (or the public defender) will review the police report, dashcam footage, breath test records, and any other evidence. Most first-time OWI cases are resolved through a plea agreement rather than trial. The prosecution may offer to reduce the charge to a lesser offense (such as impaired driving, which carries lower penalties), or you may plead guilty to OWI with an agreement on sentencing recommendations. If no agreement is reached, the case goes to trial, where the prosecution must prove guilt beyond a reasonable doubt.

At sentencing, the judge imposes fines, jail time (if any), license suspension, and any other conditions. The judge also orders you to complete a substance abuse assessment. Sentencing is also when you can present mitigating factors — your employment, family situation, lack of prior record, or steps you have already taken toward treatment — though the judge is not required to reduce penalties based on these factors.

Substance Abuse Assessment and Treatment Requirements

Every person convicted of OWI in Michigan must complete a substance abuse assessment through a provider approved by the Michigan Department of Health and Human Services. This assessment is not optional and not a punishment — it is a clinical evaluation to determine whether you have a substance use disorder and what level of treatment, if any, you need.

The assessment typically costs $300 to $500 and takes 1 to 2 hours. The assessor will ask about your drinking history, any prior treatment, family history, and the circumstances of your arrest. Based on the results, the assessor may recommend no further treatment, outpatient counseling, or more intensive treatment. If treatment is recommended, you must complete it before your license can be restored. Some courts also order you to attend a victim impact panel, which is a separate requirement where you hear from people harmed by impaired driving.

You cannot restore your license until you provide proof of assessment completion to the Secretary of State. If treatment was recommended, you must also provide proof that you completed it or are actively enrolled. This process can take several months.

Criminal Record and Long-Term Consequences

A first OWI conviction results in a permanent criminal record in Michigan. This record is public and will show up on background checks for employment, housing, professional licensing, and other purposes. Unlike some states, Michigan does not allow you to seal or expunge an OWI conviction from your record, even after a waiting period.

Beyond the legal penalties, a conviction can affect your car insurance rates (often doubling or tripling), your ability to work in certain fields (especially those requiring a commercial driver's license or a clean driving record), and your ability to travel to some countries. If you are not a U.S. citizen, a conviction may trigger immigration consequences, including deportation in some cases — this is a reason to consult an immigration attorney if you are not a citizen.

A second OWI within 7 years is charged as a felony in Michigan, not a misdemeanor. This makes the stakes of a first offense much higher: a conviction now will increase penalties dramatically if you are arrested again.

When to Contact a Criminal Defense Attorney

You should contact a criminal defense attorney as soon as possible after arrest, ideally before your arraignment. An attorney can review the police report and chemical test procedures to identify potential defects — improper administration of the breath test, lack of probable cause for the traffic stop, or violations of your rights during arrest. These defects can sometimes result in evidence being excluded or charges being reduced.

An attorney can also negotiate with the prosecution on your behalf, potentially securing a plea to a lesser charge or a sentencing recommendation that avoids jail time. Public defenders are available free if you cannot afford to hire a private attorney, and they handle OWI cases regularly. The decision to hire a private attorney is a personal one based on your financial situation and the complexity of your case.

Frequently Asked Questions

Can I get my license back before the suspension ends?

Yes, you can request a restricted license for work, school, or treatment after you complete your substance abuse assessment and show proof to the court. A restricted license allows you to drive only for specific purposes and only during certain hours. You must petition the court for this; it is not automatic, and the judge has discretion to grant or deny it.

What is the difference between OWI and DUI in Michigan?

Michigan uses the term OWI (Operating While Intoxicated), not DUI. OWI is the legal charge for drunk driving. There is also a charge called OWVI (Operating While Visibly Impaired), which is a lesser offense that applies when your BAC is between 0.04% and 0.08%, or when you show signs of impairment but your BAC is below 0.08%.

Will a first OWI show up on my driving record?

Yes. An OWI conviction is recorded on your Michigan driving record and is visible to insurance companies, employers, and anyone else who requests your record. It remains on your record permanently and cannot be removed.

Can I refuse a breath test without consequences?

You have the legal right to refuse, but refusal triggers a 1-year administrative license suspension (instead of 6 months) and the refusal can be used as evidence against you in court. In Michigan, refusing does not protect you; it typically makes your situation worse.

What happens if I miss a court date?

Missing a court date results in a bench warrant for your arrest. You will be arrested and held until you appear before the judge. This also damages your credibility with the court and can result in harsher sentencing. If you cannot make a scheduled court date, contact your attorney or the court when ready to request a continuance.
