An OWI arrest in Milwaukee starts two separate clocks, and both are already running before you leave the station. One is on your driver’s license: if you failed the test, the state issues a Notice of Intent to Suspend, and you have just 10 days to request administrative review — otherwise a six-month administrative suspension takes effect on its own 30 days after that notice is issued. The other clock is on the case itself, which moves at the pace of the court where it lands. Mays Law Office defends OWI charges — the offense most people search as DUI or DWI, though Wisconsin’s statutory name is OWI — along with drugged-driving allegations, for drivers arrested throughout Milwaukee and Milwaukee County. Mays Law Office represents clients across Wisconsin from our office in Middleton — including Milwaukee. Call 608-305-4518 for a free consultation before you talk to anyone else about the arrest.

OWI Attorneys in Milwaukee, WI

Attorney Stephen E. Mays has practiced law in Wisconsin since 1995 and was named a 2025 Wisconsin Super Lawyer in DUI/DWI defense. He belongs to the National Association of Criminal Defense Lawyers, the Wisconsin Association of Criminal Defense Lawyers, the Dane County Criminal Defense Lawyers Association, and the State Bar of Wisconsin. Milwaukee is the state’s largest city, and its court system is built to match. An OWI stop can come from any agency working these roads — city police, sheriff’s deputies, or the Wisconsin State Patrol. Knowing which agency made the stop — and which of the county’s many courtrooms the charge is routed to — shapes the defense from the outset.

An OWI lawyer earns their fee in the specifics — whether the stop was lawful, whether the field sobriety tests actually show what the officer claims, whether the blood draw held up under the Fourth Amendment, and whether every deadline that protects your license was met. Those are the questions a case needs answered from the start.

When to Call Our Milwaukee, WI OWI Lawyers

Reach out right away if any of this describes your situation:

• You were handed a “Notice of Intent to Revoke” after refusing a breath or blood test. You have 10 days to request a refusal hearing in writing — let that window close and the revocation takes effect automatically 30 days after the notice, and you forfeit the statutory chance to contest it.
• You took the test and the result was over the limit. That triggers a Notice of Intent to Suspend, and you have 10 days to request administrative review — otherwise a six-month administrative suspension begins 30 days after the notice is issued.
• You already have an OWI on your record. A second offense is a criminal misdemeanor carrying 5 days to 6 months in jail if the prior was within the last 10 years. A third runs 45 days to a year. A fourth is a Class H felony.
• A child under 16 was riding with you. That one fact turns even a first offense into a criminal misdemeanor — a $350 to $1,100 fine and a mandatory 5 days to 6 months in jail.
• Someone was hurt. Causing injury to another person while intoxicated makes even a first offense a crime, and great bodily harm or death brings separate felony charges.
• You hold a CDL. A single OWI conviction — even in your own car — disqualifies your commercial privileges for a year, and a second lifetime conviction ends them for good.
• You were at 0.15 or above. On a first offense, that reading brings a mandatory one-year ignition interlock order.

What an OWI Conviction Costs in Wisconsin

Wisconsin writes its drunk-driving law under a single name — operating while intoxicated, or OWI. People search for DUI and DWI lawyers, but those are everyday labels for the same charge. What the charge costs you depends first on your history — and then on aggravating facts like a high BAC, a refusal, or a passenger under 16. A standard first offense is not a crime at all: it is a civil forfeiture of $150 to $300 plus a mandatory $435 surcharge, with no jail — but your license is revoked for six to nine months. A second offense becomes a criminal misdemeanor when the prior falls within the past ten years, carrying five days to six months in jail. At the third offense, the counting changes: every qualifying prior in your lifetime counts — including OWI convictions, implied-consent refusal revocations, OWI-related injury convictions, and comparable out-of-state offenses — and jail runs from 45 days up to a year. A fourth offense is a Class H felony punishable by 60 days to six years of imprisonment. Certain facts short-circuit that ladder entirely — a passenger under 16 turns even a first offense into a criminal misdemeanor with a $350-to-$1,100 fine and a mandatory five days to six months behind bars. An ignition interlock is required after a test refusal, a first offense at 0.15 or above, or any repeat offense. An occupational license may keep you driving to work, but eligibility is never automatic — it depends on the type of suspension, any interlock requirement, the rest of your record, and DMV approval. And whichever way your case starts, you generally have just 10 days from your notice to request a refusal hearing or administrative review.

The fine on the citation is the smallest number in an OWI case. Wisconsin adds a mandatory $435 surcharge to every OWI conviction, and the court-ordered alcohol and drug assessment typically runs $165 to $500 depending on the county. If an interlock is ordered, plan on roughly $50 to $150 for installation and $60 to $100 a month while the order lasts. Getting your license back costs another $200 reinstatement fee, and SR-22 high-risk insurance keeps raising the price for years afterward. Add it together and a typical first offense lands between $4,000 and well over $10,000 all-in. Those are typical ranges, not quotes — your county, your vendor, and your insurer set the real numbers.

How OWI Cases Move Through Milwaukee and Milwaukee County Courts

Milwaukee County runs the largest circuit in the state — 47 judicial branches at the Milwaukee County Courthouse, 901 N. 9th Street in downtown Milwaukee — and where your OWI lands inside that system turns on the offense number. A standard first offense is not a crime in Wisconsin. It is a civil forfeiture, and depending on which agency wrote the citation and which jurisdiction it came from, it can be handled in a municipal court — Milwaukee operates one — or in the Milwaukee County Circuit Court. Either way it is a non-criminal proceeding, but the standard of proof in a municipal OWI trial is still demanding: the government must prove the case by evidence that is “clear, satisfactory and convincing,” a higher bar than the ordinary civil standard.

Criminal OWI cases — a second or subsequent offense, or a first offense involving a minor passenger or injury — are heard at the Milwaukee County Circuit Court at 901 N. 9th Street and prosecuted by the county District Attorney’s office. An OWI stop can come from any agency working these roads — city police, sheriff’s deputies, or the Wisconsin State Patrol. Which agency stopped you can affect the reports, the squad video, and how the case is built, which is one of the first things our Wisconsin OWI defense practice sorts out.

The criminal track follows a set path. The arresting agency forwards its file to the District Attorney, who issues a criminal complaint; you make an initial appearance; contested issues get litigated at motion hearings; and if a pretrial conference produces no resolution, the case goes to trial, where the State must prove guilt beyond a reasonable doubt.

How We Defend OWI Charges

An OWI prosecution is a chain of moving parts, and each part can fail. The first is the stop itself: an officer needs reasonable suspicion to pull you over and probable cause to arrest, and when either is missing, a court can suppress the evidence gathered afterward. The second is the roadside testing. The three standardized field sobriety tests were validated on narrow research populations, and age, weight, injuries, medical conditions, footwear, and the weather can all generate “clues” in a perfectly sober driver. The third is the chemical evidence. A breath number at or near the legal limit — 0.08 for most drivers, though stricter limits apply behind the wheel of a commercial vehicle (0.04), for drivers under 21 (absolute sobriety), and for drivers under an interlock order or with three or more priors (0.02) — is a measurement, not a verdict — the reliability of chemical testing is one of the recognized fronts for challenging an OWI, and once you submit to the agency’s primary test, Wisconsin law lets you request the agency’s alternative test free of charge — or arrange a test of your own choosing at your own expense. Blood draws raise a separate constitutional question: taking blood is a Fourth Amendment search, and in State v. Prado (2021) the Wisconsin Supreme Court struck down the implied-consent provision that presumed consent from an incapacitated driver. Not every warrantless draw gets suppressed — the State can point to exceptions like exigent circumstances — but a draw taken without a warrant and without valid consent deserves scrutiny in every case. Finally, the State must prove “operation” — the physical manipulation or activation of a vehicle’s controls necessary to put it in motion. That element is fact-specific, and facts can be contested. Which of these doors is open in your case depends on the reports, the video, and the timeline — call 608-305-4518 before those details go cold.

We also handle the license side of the case — refusal hearings and occupational license applications. An occupational license is not automatic; eligibility depends on the type of suspension, any interlock requirement, other suspensions on your record, and DMV approval, so the paperwork is worth getting right the first time.

Milwaukee OWI Questions We Hear Most

Where will my Milwaukee OWI case actually be heard?

That depends on the charge. A standard first-offense OWI is a civil forfeiture, not a crime, and — depending on which agency cited you and which jurisdiction it came from — it may be handled in a municipal court, which Milwaukee operates, or in the Milwaukee County Circuit Court. Every criminal OWI — a second or subsequent offense, or a first offense with a minor passenger or injury — is filed and prosecuted in the Milwaukee County Circuit Court at the county courthouse, 901 N. 9th Street in downtown Milwaukee, one of 47 judicial branches there. So whether your stop came from Milwaukee police, a suburban department, the county sheriff, or a State Patrol trooper on the freeway, a criminal case runs through that courthouse.

Will I go to jail for a first-offense OWI in Wisconsin?

For a standard first offense, no. Wisconsin is the only state that treats a first OWI as a non-criminal civil forfeiture — a fine and license revocation, but no jail. That changes fast if a child under 16 was in the car — a criminal misdemeanor with a mandatory 5 days to 6 months in jail — or if anyone else was injured, which also criminalizes the charge.

I have a CDL. What does an OWI do to my commercial license?

A first OWI conviction disqualifies your commercial driving privileges for 1 year — even if you were driving your personal vehicle at the time — and for 3 years if you were hauling placarded hazardous materials. A second lifetime OWI conviction means lifetime CDL disqualification. Commercial drivers also operate under a stricter 0.04 limit in a commercial vehicle, and any detectable alcohol triggers an immediate 24-hour out-of-service order.

I was asleep in a parked car. Can they really charge me?

Yes. Wisconsin law punishes “operating,” not just driving — the physical manipulation or activation of any control of the vehicle necessary to put it in motion. Depending on the facts, a driver found asleep behind the wheel with the engine running can be prosecuted for OWI even though the car never moved.

I wasn’t impaired — can they still charge me for drugs in my system?

Yes. Wisconsin’s restricted-controlled-substance law is zero-tolerance: operating with a detectable amount of a restricted controlled substance such as cocaine, methamphetamine, or Delta-9-THC in your blood supports a charge regardless of whether you showed any actual impairment — the one narrow statutory exception is Delta-9-THC below one nanogram per milliliter of blood. And because Wisconsin does not recognize recreational or medical marijuana, a prescription or legal purchase in another state is not a defense.
