4th-Offense OWI/DUI (Felony) in Wisconsin: Penalties, Defenses, and What to Expect

Since 2015 Wisconsin Act 371 took effect on January 1, 2017, every fourth or subsequent OWI in Wisconsin is automatically a Class H felony, regardless of when the prior offenses occurred. The maximum penalty is 6 years in prison and a $10,000 fine. For 4th-offense counting, Wisconsin reaches back to January 1, 1989. A 1st offense from 1990 counts the same as one from last year.

What makes a 4th-offense OWI a felony?

Wisconsin Statute §346.65(2)(am)(4) classifies a 4th or subsequent OWI violation as a Class H felony. Before 2015 Wisconsin Act 371 took effect on January 1, 2017, the felony threshold was the 5th offense. The legislature moved it down by one. The change was not retroactive. It applies to offenses committed on or after January 1, 2017.

The prior-offense count includes all qualifying Wisconsin OWI convictions (including civil forfeitures), refusal revocations, and qualifying out-of-state convictions. For 4th-offense counting, there is no 10-year window. Priors are counted back to January 1, 1989 under §343.307(1).

Bail and bond: Felony OWI defendants are typically held on a cash bail with conditions that include absolute sobriety, no driving without a valid license, and installation of an IID if bond is posted. Violating conditions can lead to bail revocation. Call us before your initial appearance if possible.

The real-world consequences of a felony record

A felony conviction in Wisconsin does far more than impose a sentence. It triggers a cascade of collateral consequences that persist long after the sentence is served:

Defense strategies for felony OWI

Prior-offense challenge

The state must prove each prior offense that elevates the charge. We examine every prior conviction for constitutional defects: Was the defendant represented by counsel? Was the plea voluntary and informed? Was jurisdiction proper? An uncounseled prior conviction that resulted in jail time cannot be used for enhancement under Nichols v. United States. Striking even one prior can reduce the charge from a felony to a 3rd-offense misdemeanor.

Suppression of the stop and arrest

The Fourth Amendment doesn’t bend because the charge is a felony. Every challenge available in a 1st-offense case (illegal stop, improper field sobriety testing, defective breath or blood testing) applies with even higher stakes here. A successful suppression motion can collapse the entire case.

Blood and breath test challenges

At this offense level, the BAC result drives both the severity of the sentence and the length of the IID requirement. We retain independent toxicologists to review lab procedures, calibration records, and chain of custody. Common issues include:

Sentencing alternatives

Even when a conviction is unavoidable, the sentence is not predetermined. Wisconsin law allows courts to consider:

The timeline of a felony OWI case

  1. Arrest & booking: You are booked into county jail. Bond is set at the initial appearance, typically within 48 hours.
  2. Preliminary hearing: Within 10 days if in custody, 20 if released on bond. The state must show probable cause.
  3. Arraignment: Formal reading of charges. Plea entered.
  4. Pretrial motions: Suppression motions, prior-offense challenges, expert discovery. This is where most cases are won or lost.
  5. Trial or negotiation: Jury trial is a constitutional right at the felony level. Plea negotiations run in parallel.
  6. Sentencing: If convicted, sentencing considers the PSI report, treatment evaluations, victim impact, and defense mitigation.

Do not wait. Felony OWI cases move fast once charges are filed. Early attorney involvement, ideally before the initial appearance, gives us the widest range of options. Call (262) 632-5000 now. We serve Racine, Kenosha, and Walworth counties.

Frequently asked questions

When did a 4th OWI become a felony in Wisconsin?
2015 Wisconsin Act 371 moved the felony threshold from the 5th offense to the 4th offense, effective January 1, 2017. Before that, a 4th OWI was a misdemeanor unless the prior offenses fell within a 5-year window. The change was not retroactive. It applies to offenses committed on or after January 1, 2017. For 4th-offense counting, priors back to January 1, 1989 are counted regardless of when they occurred.
Will I go to prison for a 4th-offense OWI in Wisconsin?
A Class H felony carries up to 6 years in prison (3 years initial confinement plus 3 years extended supervision) and up to $10,000 in fines. Prison is a realistic outcome, but alternatives exist: treatment courts, electronic monitoring, Huber privileges, and carefully negotiated extended supervision conditions. Early attorney involvement maximizes the chance of avoiding state prison.
Can a felony OWI be reduced to a misdemeanor by challenging a prior conviction?
Yes. The state must prove each prior offense used to elevate the charge. If any prior conviction has constitutional defects (uncounseled pleas, defective colloquies, jurisdictional errors) it cannot be used for enhancement. Striking even one prior drops a 4th-offense felony to a 3rd-offense misdemeanor, eliminating the possibility of state prison.
What are the firearm consequences of a felony OWI conviction?
A Wisconsin felony conviction — including a Class H felony 4th-offense OWI — triggers the lifetime federal firearm ban under 18 U.S.C. §922(g)(1) and the parallel state ban in Wis. Stat. §941.29. Possession of any firearm or ammunition after conviction is itself a Class G felony, carrying up to 10 years in prison. Restoration is possible only through a gubernatorial pardon in Wisconsin or, for federal purposes, through §925(c) relief (currently unfunded and therefore practically unavailable). This is frequently the most durable collateral consequence of a felony OWI.
Does the BAC enhancement apply to a 4th-offense felony OWI?
Yes. Wis. Stat. §346.65(2)(g) stacks on top of the felony penalty. At a BAC of .17–.199 the mandatory minimum doubles; .20–.249 triples it; .25 and above quadruples it. Combined with the Class H felony baseline under §346.65(2)(am)4, a 4th offense with a BAC near .25 can carry a mandatory minimum that exceeds a year in confinement before any sentence-credit or probation calculation. This is why breath/blood suppression motions are often the highest-leverage play in a felony OWI case.
