What Is the Penalty for a 5th OWI in Wisconsin?

The penalty for a 5th OWI in Wisconsin is a Class G felony conviction carrying a mandatory minimum of 18 months in prison, fines of up to $25,000, and in most cases permanent revocation of your driver’s license.¹ The courtroom sentence is only the start. A felony conviction also strips your firearm rights, puts an ignition interlock on every vehicle you own once you can drive again, closes the Canadian border to routine entry, and ends a commercial driving career for good.

Prison Time and Fines

A fifth OWI requires a bifurcated sentence. The judge imposes a term of confinement in prison followed by a period of extended supervision. The confinement portion must be at least 18 months.¹ Because the offense is a Class G felony, the maximum exposure is 10 years of imprisonment plus a fine of up to $25,000.² The minimum fine is $600.

There is one narrow escape from the 18-month floor. A judge may set confinement lower if the court finds that doing so serves the community’s best interests and the public won’t be harmed, and the reasoning has to be stated on the record.¹ For someone with five OWI convictions, this exception almost never applies in practice.

Extended Supervision After Release

After you serve the prison portion of the sentence, you move onto extended supervision. This is a structured period of release where you must comply with conditions set by the court and the Department of Corrections. For a Class G felony, extended supervision can run as long as five years and must be at least 25 percent of the confinement term.³ If you serve the 18-month minimum, you face at minimum roughly five additional months of supervision, and often substantially more.

Violations send you back. Missing check-ins, drinking, or picking up new charges while on supervision can mean returning to prison to serve out the remaining supervision time.

License Revocation

Two separate license consequences apply, and both are triggered. The sentencing court orders a revocation of two to three years under the OWI penalty statute for anyone with three or more counted offenses.⁴ The harder blow comes from the Department of Transportation: once your counted offenses reach four or more in your lifetime, the department permanently revokes your operating privilege.⁵

Permanent revocation shuts the door on occupational licensing during the revocation period, so there is no limited work-only driving. After 10 years, you can apply for reinstatement through a separate process, but approval is not guaranteed.⁵

One carve-out exists. Permanent revocation does not apply if your most recent counted offense occurred more than 15 years after the preceding one. In that situation you’d face the court-ordered two-to-three-year revocation instead and would eventually become eligible for an occupational license after a 45-day waiting period.⁶ For most people reaching a fifth offense, the convictions are packed closely enough that permanent revocation applies.

Ignition Interlock Device

Every repeat OWI offender in Wisconsin must install an ignition interlock on every vehicle they own or have registered in their name.⁷ The device requires a breath sample before the engine will start and blocks ignition if it reads alcohol. The minimum IID period is 12 months, and the court can order longer based on your revocation timeline.

You can’t wait it out. The IID clock only starts the day you’re actually issued a Wisconsin driver’s license or occupational license after conviction.⁷ For someone under permanent revocation who can’t get a license for at least 10 years, the IID requirement sits on top of that wait.

You pay all the costs yourself: installation, monthly lease, and calibration appointments. A reduced price may be available if your annual income is below 150 percent of the federal poverty level, which you arrange through the convicting court.⁷ Tampering with the device, disconnecting it, having another person blow for you, or failing to install it when required carries fines of $150 to $600, up to six months in jail, and a mandatory six-month extension of the IID order. A second violation within five years raises the fine ceiling to $1,000.⁸

Required Alcohol and Drug Assessment

Within 72 hours of conviction you must contact the Intoxicated Driver Program assessment facility approved for your county.⁹ The assessor evaluates your alcohol or drug use and writes a driver safety plan, which may require education, counseling, or inpatient treatment.¹⁰ You pay for both the assessment and whatever treatment the plan calls for, and the plan must be completed within one year. If you don’t comply, your operating privileges stay revoked until you do.

When the Penalties Get Worse

Certain facts about the offense drive the already-severe fifth-offense penalties higher.

High BAC

Wisconsin uses a tiered multiplier on fines based on the BAC reading at the time of the offense:

0.17 to 0.199: minimum and maximum fines doubled
0.20 to 0.249: minimum and maximum fines tripled
0.25 or above: minimum and maximum fines quadrupled

At a 0.25 BAC or higher on a fifth offense, the fine range runs from $2,400 to $100,000.¹ The multipliers hit fines only, not prison time.

Minor Passenger Under 16

If a child under 16 was in the vehicle, the minimum and maximum fines and the minimum and maximum terms of imprisonment are all doubled.¹¹ On a fifth offense, that pushes the mandatory minimum confinement from 18 months to 3 years and the maximum prison term from 10 years to 20 years. The high-BAC multiplier and the minor-passenger enhancement can stack.

Injury or Death

Causing great bodily harm while driving intoxicated is a separate charge under a different statute, prosecuted as a Class F felony with up to 12.5 years in prison.¹² Killing someone while intoxicated can be charged as homicide by intoxicated use of a vehicle, a Class D felony with a maximum of 25 years. These charges stack onto the OWI penalties rather than replace them, and four prior convictions make a harsher sentence more likely.

Vehicle Forfeiture

Because a fifth OWI is a felony, Wisconsin law allows the state to seize and forfeit the vehicle used to commit the offense.¹³ Even where forfeiture isn’t pursued, the court can order the vehicle immobilized or impounded. Losing the vehicle entirely is a real possibility and a real financial cost on top of the fines.

Life After Conviction

A Class G felony follows you well past the sentence itself.

Firearms

Anyone convicted of a felony in Wisconsin is prohibited from possessing a firearm. Violating that ban is itself a Class G felony carrying up to 10 years.¹⁴ The federal prohibition under 18 U.S.C. § 922(g) applies as well, so a state pardon alone doesn’t restore firearm rights. If you hunt or own guns, a fifth OWI ends that in most cases permanently.

Jobs and Professional Licenses

A felony has to be disclosed on most job applications and can disqualify you from positions requiring background checks. Professional licensing boards in healthcare, law, and education can revoke or deny licenses based on a felony record. The specific impact depends on the board.

Travel to Canada

Canada treats any alcohol-related driving conviction as grounds for criminal inadmissibility. With five convictions, you are categorically inadmissible. The “deemed rehabilitation” path that can work for a single old conviction requires only one non-serious offense, which rules out multiple OWIs. Your options narrow to a Temporary Resident Permit for short trips, or formal Criminal Rehabilitation, which requires at least five years to have passed since you completed your sentence and provides a permanent fix if approved.

SR-22 Insurance

When you eventually become eligible to drive again, you have to file an SR-22 certificate of financial responsibility proving you carry the required minimum auto insurance. You must maintain it for three years from the date of eligibility, and a lapse triggers another suspension.¹⁵ Expect premiums to climb sharply, because insurers treat a felony OWI as an extreme risk.

Commercial Driver’s License

If you hold a CDL, a fifth OWI results in lifetime disqualification from commercial driving. Federal rules require permanent CDL disqualification after two or more alcohol-related driving offenses, whether or not the OWI happened in a commercial vehicle.¹⁶ For anyone whose income depends on driving a truck, bus, or delivery vehicle, that is a forced career change.

How Wisconsin Counts to Five

Wisconsin uses a lifetime lookback for OWI priors. There is no expiration on old convictions. A first offense from 30 years ago still counts.¹ Out-of-state OWI convictions, administrative suspensions, and revocations all count toward your total. Offenses from the same incident count as one.

The only place timing changes anything is the permanent-revocation exception described above. The felony classification, the 18-month minimum, and the fine range all run off the lifetime count regardless of how far back the earlier offenses sit.⁵
