A first OWI conviction in Wisconsin carries mandatory penalties: a fine between $150 and $300, a suspended license for six to nine months, and possible jail time up to six months, though jail is less common for a first offense without aggravating factors.

OWI stands for Operating While Intoxicated. Wisconsin law treats it as a criminal offense from the first charge, not a traffic violation. That means you will have a criminal record if convicted, even though the penalties for a first offense are less severe than for repeat convictions. The specific consequences depend on your blood alcohol content (BAC) at the time of arrest, whether you refused a breath or blood test, and whether any accidents or injuries occurred.

Understanding what happens next — from arrest through sentencing — helps you make informed decisions about your case. The process moves through several stages, and your choices at each one matter.

Key Takeaways

  • Wisconsin treats a first OWI as a criminal offense with a mandatory fine, license suspension, and possible jail time, even though penalties are lighter than for repeat offenses.
  • Your BAC level, whether you refused a test, and whether an accident occurred all affect the specific charges and penalties you face.
  • You have the right to an attorney, and the court will appoint one at no cost if you cannot afford one.
  • License suspension begins when ready after arrest in most cases, separate from any court sentence.
  • Diversion programs and deferred prosecution options exist in some Wisconsin counties and can result in charges being dismissed if you complete the program.

What Happens when ready After Arrest

When you are arrested for OWI in Wisconsin, the officer will take your driver's license and issue you a notice of intent to suspend it. This suspension is administrative — it happens through the Department of Motor Vehicles, not the court — and it begins either when ready or after a waiting period, depending on whether you took a breath or blood test and what the result was.

If you took a test and your BAC was 0.08 or higher, your license is suspended for six months starting on the date of arrest. If you refused the test, the suspension is nine months. You have 10 days from the date on your notice to request a hearing with the Department of Motor Vehicles to challenge the suspension. This hearing is separate from your criminal case and has its own rules and important date.

You will also be taken to a police station or jail for booking. At this point, you have the right to speak with an attorney before answering questions. You also have the right to refuse a breath or blood test, though Wisconsin's "implied consent" law means that refusal itself carries penalties — a longer license suspension and the refusal can be used against you in court.

Criminal Charges and Court Appearance

Your first court appearance is usually within 72 hours of arrest. At this appearance, called an initial appearance or first appearance, the judge will inform you of the charges, tell you about your rights, and set bail or release conditions. You do not need to enter a plea yet.

For a first OWI with no aggravating factors, the charge is typically a misdemeanor. If your BAC was 0.15 or higher, or if you refused a test, the charge may be enhanced to a higher-level misdemeanor with steeper penalties. If an accident or injury occurred, felony charges are possible.

If you cannot afford an attorney, you can request a public defender at this appearance. The court will assess your income and, if you may have access to, appoint one at no cost. Having an attorney is important because OWI cases involve technical issues — how the breath test was administered, whether the officer had legal grounds to stop you, whether your rights were read correctly — that can affect the outcome.

License Suspension and Driving Restrictions

Your license suspension is separate from any jail sentence or probation the court imposes. Even if the court does not sentence you to jail, you will lose your license for six to nine months depending on whether you took a test and what the result was.

After the suspension period ends, you must pay a reinstatement fee to the Department of Motor Vehicles to get your license back. The fee is $100 for a first offense. You may also be required to install an ignition interlock device on any vehicle you own — a device that requires you to blow into it before the car will start, to verify you have not been drinking. Wisconsin requires this for some first offenses, particularly if your BAC was high or you refused a test.

During the suspension, you cannot legally drive. Some counties offer occupational licenses that allow you to drive to work, school, or medical appointments, but you must request one from the court and meet specific conditions.

Penalties for a First OWI Conviction

If you are convicted of a first OWI in Wisconsin, the mandatory penalties are:

  • A fine of $150 to $300
  • License suspension of six to nine months (as described above)
  • Jail time of up to six months (though judges rarely impose jail for a first offense without aggravating circumstances)
  • Probation, typically one to two years
  • Court costs and fees, which vary by county but typically total $300 to $500

The judge has discretion within these ranges. A higher BAC, an accident, or prior criminal history can push the sentence toward the upper end. A lower BAC and no other factors may result in a fine and probation with no jail time.

You will also be required to complete an OWI education program, which costs money and takes several hours. Some courts also require a substance abuse assessment, which may lead to a recommendation for counseling or treatment.

Diversion and Deferred Prosecution Options

Some Wisconsin counties offer diversion programs or deferred prosecution for first-time OWI offenders. These programs allow you to avoid a conviction if you complete certain requirements — usually education, counseling, community service, or a combination of these.

Diversion is not available in all counties, and may be able to access depends on factors like your BAC level, whether an accident occurred, and your prior record. You must request this option, usually through your attorney, and the prosecutor must agree. If you successfully complete the program, the charges are dismissed and you have no criminal conviction.

This is a significant advantage because a dismissed case does not appear on your criminal record the same way a conviction does. However, the arrest itself may still be visible in some background checks. Ask your attorney whether your county offers this option and whether you might be may be able to access.

Your Rights and Next Steps

You have the right to an attorney, the right to see the evidence against you, the right to cross-examine witnesses, and the right to a trial before a judge or jury. You also have the right to negotiate a plea agreement with the prosecutor, which may result in reduced charges or penalties.

Your first step should be to request a public defender if you cannot afford an attorney, or to hire a private attorney if you can. An attorney can review the police report, the breath test results, and the circumstances of your stop to identify any legal problems that might help your case. They can also explain your options — trial, plea, or diversion — and the likely outcome of each.

Do not ignore court dates or important date. Missing a court appearance can result in additional charges and a warrant for your arrest. If you have questions about your case, ask your attorney. If you cannot reach your attorney, contact the court directly to ask about your next appearance date.

Frequently Asked Questions

Will a first OWI conviction show up on a background check?

Yes, a conviction will appear on criminal background checks. However, if you complete a diversion program and the charges are dismissed, the conviction does not appear. The arrest itself may still be visible in some background checks, but employers and landlords typically focus on convictions. Ask your attorney about diversion options in your county.

Can I get my license back before the suspension period ends?

You may be able to get an occupational license that allows you to drive to work, school, or medical appointments. You must request this from the court handling your case. may be able to access and the specific restrictions vary by judge and county.

What if I refused the breath test?

Refusing a test results in a nine-month license suspension instead of six months, and the refusal can be used as evidence against you in court. However, it also means the prosecution does not have a BAC number to prove how intoxicated you were, which can affect the strength of their case. Discuss this with your attorney.

Do I have to do jail time for a first OWI?

Jail is not mandatory for a first offense without aggravating factors. Many judges impose only a fine and probation. However, a higher BAC, an accident, or prior criminal history can result in jail time. Your attorney can discuss what outcome is likely in your specific situation.

How long does a first OWI stay on my record?

A conviction stays on your criminal record permanently in Wisconsin. However, after a certain period (typically five years for a misdemeanor), you may be able to petition the court to seal the record, which limits who can see it. Ask your attorney about sealing options after your case is resolved.
