What the statute actually says
Wisconsin Statute §346.63(1)(a) prohibits operating a motor vehicle while under the influence of an intoxicant. For a first offense with no aggravating factors, §346.65(2)(am)(1) classifies the violation as a civil forfeiture, not a misdemeanor or felony.
That distinction matters. You are not entitled to a jury trial. You are not entitled to a court-appointed attorney. You will not be booked into the county jail (unless you are held on a separate charge). But the state still must prove its case by a preponderance of the evidence, and every constitutional protection regarding the traffic stop and the arrest still applies.
Critical deadline: You have 10 days from the date of the Notice of Intent to Revoke to request an administrative review hearing with the DOT. Miss it and the revocation is automatic. If you also refused the chemical test, you have a separate 10-day window for a refusal hearing.
Do I need a lawyer for a first OWI?
You should at least have the case reviewed before you plead. A first OWI may be civil, but the license revocation, insurance impact, occupational license planning, IID questions, and future prior-counting consequences are real. Our dedicated guide explains when a first OWI needs a lawyer and what we check before any plea.

Aggravating factors that change everything
A first-offense OWI is not treated as a civil forfeiture if any of the following apply:
- Passenger under 16: Automatic penalty-tier elevation under §346.65(2)(f). Your 1st offense is punished as if it were a 2nd.
- Causing injury: Under §346.63(2)(a) and §346.65(3m), a 1st-offense OWI causing injury with no priors is a criminal misdemeanor carrying 30 days to 1 year in county jail and a $300-$2,000 fine. With any prior OWI or refusal counted under §343.307(1), it becomes a Class H felony via §346.65(3p).
- Causing great bodily harm: Charged separately under §940.25 as a Class F felony (up to 12 years, 6 months in prison).
- Causing death: Charged separately under §940.09 as a Class D felony (up to 25 years in prison), elevated to Class C (up to 40 years) with a prior OWI.
- CDL holders: Special CDL consequences including a 1-year commercial driving disqualification, even if you were driving your personal vehicle.
Common defenses we raise
Challenging the traffic stop
Law enforcement needs reasonable suspicion to initiate a traffic stop. If the stop was based on an anonymous tip, an equipment violation that didn’t exist, or officer testimony that doesn’t match the dashcam, we move to suppress everything that followed. Without the stop, there is no case.
Field sobriety test reliability
Standardized Field Sobriety Tests (SFSTs) have documented error rates even under NHTSA protocols. We scrutinize whether the officer administered them correctly, whether conditions (slope, lighting, footwear) affected results, and whether the scoring was accurate.
Breath test challenges
Wisconsin uses the Intoximeter EC/IR II. Common challenges include: failure to observe the 20-minute deprivation period, machine calibration gaps, mouth-alcohol contamination from GERD or dental work, and operator certification lapses.
Blood test chain of custody
If your BAC was obtained via blood draw, every step from the draw to the lab must comply with statutory and administrative requirements. An improperly drawn, stored, or analyzed sample can be suppressed.
Collateral consequences most people miss
- Insurance: Expect SR-22 filing and a rate increase of 50-200% for 3 years.
- Employment: While a 1st-offense OWI is civil, background checks still surface it. Jobs requiring driving (CDL, delivery, rideshare) become difficult or impossible.
- Prior-offense counting: A 1st-offense OWI stays on your DOT record and can count toward a future 2nd-offense criminal charge for 10 years. After that, a new OWI is typically prosecuted as another 1st offense, but the prior is still counted for any eventual 3rd offense or felony 4th offense, where the statute counts qualifying priors back to January 1, 1989.
- Occupational license: You may be eligible for an occupational (hardship) license during the revocation period. We file these the same week whenever possible to minimize the impact on your employment.
Why fight a civil forfeiture?
Because the consequences aren’t civil. The revocation, the DOT record, the insurance hit, and the prior-offense counting rules in §343.307 mean that a 1st offense you don’t contest is a loaded gun pointed at your future. If there is any viable defense, and there often is, the cost of fighting it now is a fraction of the cost of carrying it for decades.
