Kenosha OWI Defense Attorney

If you are arrested for an OWI in Wisconsin, you have 10 days to request an administrative hearing to keep your license. Penalties for a first offense typically include fines and license revocation, but no jail time, while subsequent offenses carry mandatory jail sentences.

Each year, thousands of Wisconsin residents, are convicted of drunk driving offenses that result in harsh penalties from fines to jail time. In 2012, there were over 4,900 alcohol-related accidents in Wisconsin. While drunk drivers must be held accountable for their actions, especially when innocent lives are at stake, some drivers feel as if they are wrongly convicted. It is illegal to drive under the influence of alcohol in Wisconsin, however, the penalties are typically based on blood alcohol content (BAC) and driver’s prior convictions.

If you are convicted of a drunk driving offense, a Kenosha OWI defense attorney may be able to reduce your penalty or amend the conviction to a different charge altogether. When you are facing any serious offense, you need an experienced attorney to help you examine your case and offer strategies to help you reduce or dismiss the charges you are facing. Patrick Cafferty, an experienced and aggressive Kenosha OWI defense lawyer, will look at your case and determine if any mistakes took place during your drunk driving offense, such as a misreading of your BAC. Attorney Cafferty is hardworking and is respected by fellow prosecutors and judges and for more than 20 years, he has successfully defended hundreds of Wisconsin drunk driving cases.

What is an OWI?

OWI (Operating While Intoxicated) is often known as DWI (Driving While Intoxicated) or DUI (Driving Under the Influence) in other states, but generally mean the same thing; a driver was driving while under the influence of alcohol. In Wisconsin, the penalties for OWI are dependent on factors such as your BAC and driving record. Consulting with or hiring an experienced and aggressive attorney may also determine the type of penalty you face.

The Governing Wisconsin Statute

The law at a glance

The operative statute is § 346.63, which prohibits operating a motor vehicle on a public roadway while under the influence of an intoxicant. A companion provision at § 346.63(1)(b) prohibits operating with a prohibited alcohol concentration: .08 for most drivers, .04 for commercial drivers, and .02 for drivers with three or more prior OWI convictions. Drivers under 21 are covered by § 346.63(2m), which prohibits driving with an alcohol concentration of more than 0.0 but not more than 0.08.

The State has to prove three elements: operation of a motor vehicle, on a public roadway, while either impaired or with a prohibited BAC. Each element is independently contestable. Penalty tiers sit at § 346.65, with aggravators for high BAC, minors in the vehicle, and injuries caused.

OWI types

Wisconsin OWI can be alcohol, drugs, or both

Wisconsin uses one OWI framework, but prosecutors can prove it in several ways. A case may be based on officer observations, a breath number, a blood result, or a prohibited controlled substance detected in blood.

Impairment OWI

§ 346.63(1)(a) focuses on whether alcohol, drugs, or a combination made the driver less able to safely operate. Field sobriety tests, driving, speech, balance, and officer observations matter.

Prohibited alcohol concentration

§ 346.63(1)(b) is number-driven: .08 for most drivers, .04 for CDL operation, and .02 for drivers with three or more priors. The defense often turns on testing procedure and timing.

Restricted controlled substance

§ 346.63(1)(am) covers detectable restricted controlled substances in blood, including THC. In 2026, Act 99 roadside saliva screening can be the first step toward the blood draw. See our saliva-test guide.

  • Identify which OWI theory the State is actually relying on before evaluating plea options.
  • Challenge the stop and arrest before treating the chemical-test result as inevitable.
  • In THC cases, separate detection from impairment and review the blood-test timeline carefully.
  • Use RacineOWI's OWI explainer for a deeper county-by-county breakdown.

Frequently Asked Questions

What does OWI mean in Wisconsin?
OWI stands for Operating While Intoxicated. It is the Wisconsin statutory term for what other states call DUI or DWI. The conduct is prohibited at § 346.63: operating a motor vehicle on a public roadway while impaired, OR with a prohibited alcohol concentration (.08 general, .04 CDL, .02 under-21 or 3+ priors), OR with any detectable restricted controlled substance.
What's the difference between OWI and DUI in Wisconsin?
Same conduct, different label. Wisconsin uses OWI; Illinois, Michigan, and most other states use DUI or DWI. Out-of-state DUI/DWI convictions count as prior offenses under § 343.307: within a 10-year window for 2nd-offense charging in Wisconsin, and back to January 1, 1989 for 3rd-offense and above.
Is a first-offense OWI a crime in Wisconsin?
No. Wisconsin is the only state that classifies a first OWI as a civil forfeiture rather than a crime. There is no jail, no criminal record at the DOJ, and no CCAP criminal entry (though the citation appears on CCAP and the DOT MVR). A second offense within 10 years is a criminal misdemeanor under § 346.65(2). A fourth is a Class H felony under 2015 Act 371.
How long do you go to jail for an OWI in Wisconsin?
Per § 346.65: 1st, no jail (civil forfeiture). 2nd within 10 years, mandatory 5 days minimum under § 346.65(2)(am)2 up to 6 months. 3rd, 45 days to 1 year. 4th is a Class H felony with up to 6 years prison (2015 Act 371, effective Jan 1, 2017). Aggravators (BAC .17+, minor passenger, injury) escalate the floor substantially.
What is the BAC limit in Wisconsin?
.08 for most drivers under § 346.63(1)(b). .04 for commercial drivers (CDL). .02 for drivers with 3 or more prior OWI-related convictions. Drivers under 21 are covered by § 346.63(2m), which prohibits driving with an alcohol concentration of more than 0.0 but not more than 0.08. Driving with any detectable amount of a restricted controlled substance is also prohibited under § 346.63(1)(am), regardless of impairment.
How long does an OWI stay on your record in Wisconsin?
Permanently on the DOT driving record. OWI convictions count as priors under § 343.307: 10-year lookback for 2nd-offense charging, and for life (back to January 1, 1989) for 3rd-offense and above. Criminal OWIs (2nd and up) also leave permanent DOJ and CCAP records. Expungement under § 973.015 does not generally reach OWI.
Will an OWI show up on a background check?
Depends on the check. A 1st-offense OWI does not appear on a Wisconsin DOJ criminal background check (it's a civil forfeiture), but it does appear on the DOT MVR and on CCAP (Wisconsin's public court records portal). A 2nd-or-above OWI is criminal and appears on every standard check (DOJ, FBI, CCAP, MVR). CDL holders trigger FMCSA Clearinghouse entries under 49 CFR Part 382.
Should I plead guilty to OWI?
Do not plead as a first response. The State has to prove probable cause for the stop, lawful arrest, properly administered field sobriety tests, calibration history of the breath instrument, and chain of custody for blood draws. Each point can be challenged. Pleading guilty forfeits suppression motions, refusal-hearing leverage, and any negotiated reduction under § 346.62.
Can an OWI charge be dismissed in Wisconsin?
Yes, with the right facts and motion practice. Dismissals come from Fourth Amendment suppression of all alcohol evidence (the case collapses), refusal-hearing dismissals under § 343.305(9), proof failures at trial on operation or public roadway, or negotiated dismissal in exchange for a non-OWI plea. Reduction to reckless driving under § 346.62 is more common than outright dismissal.
