What Happens When You Get a DUI in Wisconsin?

Getting arrested for a DUI in Wisconsin sets two separate processes in motion at the same time: an administrative case through the Department of Transportation that can take your license within weeks, and a court case that handles fines, a mandatory alcohol assessment, and possible jail time. Wisconsin actually calls the offense “Operating While Intoxicated,” or OWI, and the word “operating” is broader than driving — turning the key in a parked car can be enough. A first offense is a civil forfeiture rather than a crime, but the total cost still routinely runs into the thousands, and a second offense within 10 years becomes a criminal misdemeanor with mandatory jail time.

Two Cases Start the Moment You’re Arrested

The administrative case is run by the DMV and deals only with your license. The court case handles the charge itself. They move on separate timelines, follow separate rules, and can produce separate penalties against your license that stack on top of each other. Missing a deadline in one does not pause the other.

Which administrative path you’re on depends on a single choice at the time of arrest: whether you took the chemical test or refused it. Under Wisconsin’s Implied Consent Law, driving on state roads already counts as agreeing to submit to a test when an officer has probable cause.

If You Took the Test and Failed

The officer issues a Notice of Intent to Suspend. You then have 10 business days to request an administrative review hearing in writing, or 13 business days if the notice was mailed rather than handed to you. Miss that window and a six-month suspension takes effect automatically. The hearing examiner reviews whether the officer followed proper procedure; if everything checks out, the suspension stands.1Wisconsin Department of Transportation. Administrative Review Hearing

If You Refused the Test

Refusal carries harsher administrative consequences than failing. A first refusal is a one-year license revocation, and you cannot apply for an occupational license for the first 30 days. A second refusal is a two-year revocation, and a third or subsequent refusal is three years. Having a passenger under 16 in the vehicle doubles those periods.2Wisconsin State Legislature. Wisconsin Code 343.305 – Tests for Intoxication

What a First Offense Actually Costs

A first OWI is classified as a civil forfeiture, not a crime.3Wisconsin Department of Transportation. First OWI Offense That label is misleading because the financial side still lands hard.

The base forfeiture is $150 to $300. On top of that come a $435 driver improvement surcharge, a safe ride surcharge, court costs, penalty assessments, and additional fees.4Wisconsin Department of Transportation. OWI and Related Alcohol and Drug Offense Penalties Court-imposed totals for a first offense routinely exceed $1,000 before you add attorney fees, the alcohol assessment, or an ignition interlock device.

Jail time is not part of a standard first-offense sentence absent aggravating factors. The court does order a mandatory assessment through Wisconsin’s Intoxicated Driver Program. You have 72 hours after conviction to contact the approved assessment facility in your county.5Wisconsin Department of Transportation. OWI Assessment and Driver Safety Plan The assessment produces a driver safety plan that can range from a group traffic safety class to a 30-day inpatient treatment program, depending on what the evaluator finds.6Wisconsin Department of Health Services. Intoxicated Driver Program You pay for the assessment and any treatment yourself. Skipping it, or failing to complete the plan, gets your license withdrawn.

If your BAC was 0.15% or higher, the court must also order an ignition interlock device on every vehicle you own or have registered in your name, for a minimum of 12 months.7Wisconsin Department of Transportation. Ignition Interlock Device (IID) The device requires you to pass a breath test before the vehicle will start. The average annual cost runs about $1,500 per device. Low-income offenders earning below 150% of the federal poverty level qualify for a 50% reduction in installation and maintenance costs.8Wisconsin Department of Transportation. IID Fees

Getting Back on the Road

A first-offense conviction carries a court-ordered license revocation of six to nine months, separate from any administrative suspension. For a first offense, you can apply for an occupational license immediately, with no waiting period.9Wisconsin State Legislature. Wisconsin Code 343.30 – Suspension and Revocation An occupational license lets you drive for work, school, church, and other essential errands within specified hours and routes.

The application goes through the DMV and requires proof of SR-22 insurance, a certificate showing you carry at least the state’s minimum liability coverage.10Wisconsin Department of Transportation. Occupational License One detail trips people up: SR-22 is not technically required after a revocation that stems solely from a first OWI, but you cannot get an occupational license during that revocation without one on file. For second and subsequent offenses, the SR-22 must stay on file for three years from the date you become eligible to reinstate.11Wisconsin Department of Transportation. Proof of Insurance (Financial Responsibility)

Repeat offenders face mandatory waiting periods before applying. After a second offense, you must wait 45 days and complete the alcohol assessment first. After a third or subsequent offense, the wait is also 45 days, extending to a full year if you have two or more offenses within any five-year period.9Wisconsin State Legislature. Wisconsin Code 343.30 – Suspension and Revocation

How Fast Penalties Escalate

The jump from a first to a second OWI in Wisconsin is enormous. A first offense is civil, with no jail. A second within 10 years becomes a criminal misdemeanor with mandatory incarceration. By the fourth offense, it is a felony.

Every repeat offense also carries the $435 driver improvement surcharge, and every repeat offender must have an ignition interlock device installed.7Wisconsin Department of Transportation. Ignition Interlock Device (IID) Wisconsin also imposes a permanent lifetime revocation when someone accumulates four or more impairment-related offenses with the fourth occurring within 15 years of the previous one.12Wisconsin Department of Transportation. Lifetime Revocation

Aggravating Factors That Change Everything

Two factors can convert what looks like a routine first offense into something much worse.

A passenger under 16. Having a child under 16 in the vehicle doubles the applicable minimum and maximum penalties. For a first offense, that transforms the civil forfeiture into a criminal charge carrying a $350 to $1,100 fine and 5 days to 6 months in jail.13Wisconsin State Legislature. Wisconsin Code 346.65 – Penalty for Violating Sections 346.62 to 346.64 The license revocation also doubles, to 12 to 18 months for a first offense.9Wisconsin State Legislature. Wisconsin Code 343.30 – Suspension and Revocation For a third or higher offense with a minor passenger, the charge is automatically a felony.

High BAC on a third or subsequent offense. Starting with the third offense, an elevated BAC multiplies the applicable fines: 0.17% to 0.199% doubles them, 0.20% to 0.249% triples them, and 0.25% or above quadruples them.13Wisconsin State Legislature. Wisconsin Code 346.65 – Penalty for Violating Sections 346.62 to 346.64 This escalator does not apply to a first or second offense. On a first offense, a BAC of 0.15% or higher triggers the ignition interlock requirement but does not change the forfeiture amount.

If You Hold a CDL

Commercial driver’s license holders face federal consequences stacked on top of Wisconsin’s. A single DUI conviction in any vehicle, including your personal car on a day off, results in a one-year disqualification from operating a commercial motor vehicle. A second DUI conviction in any vehicle is a lifetime CDL disqualification.14eCFR. 49 CFR 383.51 – Disqualification of Drivers The BAC limit for commercial vehicle operators is also just 0.04%, half the standard threshold.15Wisconsin State Legislature. Wisconsin Code 346.63 – Operating Under Influence of Intoxicant or Other Drug For anyone whose work depends on a CDL, even a first OWI in a personal car can end a career.

If You Travel to Canada

Canada treats impaired driving as a serious crime under its immigration law, and a single DUI conviction — even a U.S. misdemeanor — can make you criminally inadmissible at the border. Officers have access to U.S. criminal databases and can turn you away at any crossing. Three paths exist to overcome the inadmissibility: a Temporary Resident Permit for a specific trip, Criminal Rehabilitation once at least five years have passed since you completed your entire sentence, and Deemed Rehabilitation, which in limited cases clears a single older offense automatically.16Government of Canada. Overcome Criminal Convictions Because Wisconsin’s first-offense OWI is a civil forfeiture rather than a criminal conviction, its treatment at the Canadian border is less predictable than a second or later offense.

Insurance and Employment Afterward

Court costs are only part of the hit. Car insurance premiums climb sharply after an OWI, with national data showing an average increase of roughly 92%, and that higher rate typically persists for three to five years. In practice, that means paying about $2,300 more per year for the same coverage. Add the base forfeiture, surcharges, assessment and treatment costs, a possible interlock device at about $1,500 per year, and attorney fees that commonly run from $1,500 to $10,000, and total costs for a first offense frequently land between $5,000 and $15,000. None of the fines or surcharges paid to the court are tax-deductible.

On the employment side, Wisconsin law lets an employer refuse to hire or fire someone over a conviction only when the conviction is “substantially related” to the job. A drunk driving conviction clearly relates to a trucking or delivery position but generally has no connection to a desk job or retail work.17Wisconsin Department of Workforce Development. Arrest and Conviction Record Because a first-offense OWI is a civil forfeiture, it may not appear on a standard criminal background check the way a misdemeanor or felony would. Second and subsequent offenses are criminal convictions and will show up. Any OWI that results in a license revocation affects jobs that require driving as a condition of employment.
