An OWI arrest in Fond du Lac starts two separate fights, and the first one is quiet. Whether you refused testing or failed it, you generally have just 10 days from your notice to request a hearing or review — miss that window and the suspension or revocation takes hold on its own 30 days after the notice is issued, before your case in court has even been scheduled. The second fight is the charge itself. 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, throughout Fond du Lac and Fond du Lac County. We work from our Middleton office and appear where Fond du Lac cases are decided, from the city’s municipal court to the county courthouse on Macy Street.

OWI Attorneys in Fond du Lac, 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. Fond du Lac is an east-central Wisconsin manufacturing city and the seat of its county, which means an OWI charge here can land in either of two very different rooms — a municipal courtroom for a civil first offense, or the county circuit court for anything criminal. Knowing which track your case is on, and who prosecutes it, shapes the defense from the first day.

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 Fond du Lac, WI OWI Lawyers

Reach out right away if any of this fits 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 give up the statutory chance to contest it.
• You took the test and blew over the limit. That triggers a Notice of Intent to Suspend, and you have 10 days to request administrative review — otherwise a 6-month administrative suspension takes effect 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 single 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 Fond du Lac and Fond du Lac County Courts

A first-offense OWI in Fond du Lac usually starts in a smaller room than people expect. Because a standard first offense is a civil violation rather than a crime, a first offense written under a local ordinance can be handled in municipal court, while others go to the circuit court; either way it stays a civil matter. That setting matters: in a Wisconsin municipal OWI trial the burden of proof is “clear, satisfactory and convincing” evidence, not the “beyond a reasonable doubt” standard of a criminal case, and the forfeiture is paid to the court rather than folded into a criminal sentence. It is still a contested proceeding, and it still leaves a permanent mark on your driving record — which is exactly why a first offense is worth defending, not just paying.

Everything above a civil first offense moves to the county’s criminal track. A criminal OWI — a second offense committed within 10 years of a prior, a third or later offense, or a first offense involving a minor passenger or an injury — is filed in the Fond du Lac County Circuit Court at the county courthouse, 160 S. Macy Street in Fond du Lac, and prosecuted by the county District Attorney’s Office. (A second offense more than 10 years after the first may instead be treated as a civil forfeiture rather than a crime.) The circuit court runs five branches, so a case here is heard alongside the county’s full criminal docket. Whichever agency made the stop, the reports, the squad video, and the timeline that agency created become the raw material of the case — and sorting out which of those hold up is one of the first things our Wisconsin OWI defense practice works through.

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.

Fond du Lac OWI Questions We Hear Most

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.

Where will my Fond du Lac OWI case actually be heard?

That depends on the charge. A standard civil first offense may be handled in municipal court when it is written under a local ordinance — where the burden of proof is “clear, satisfactory and convincing” evidence rather than the criminal “beyond a reasonable doubt” standard — while other first offenses go to the circuit court; either way, a first offense stays a civil forfeiture. Any criminal OWI — a second offense within 10 years of a prior, a third or later offense, or a first offense with a minor passenger or an injury — is filed in the Fond du Lac County Circuit Court at 160 S. Macy Street and prosecuted by the county District Attorney. (A second offense more than 10 years after the first can instead be treated as a civil forfeiture.) Fond du Lac is the county seat, so the criminal courthouse is right in town, and the circuit court runs five branches to handle the county’s caseload.

Can I still drive to work?

Often, yes — but it is not automatic. An occupational license permits up to 12 hours of driving per day and 60 hours per week for work, school, medical appointments, treatment, and essential household duties — never recreation. Eligibility depends on the type of suspension or revocation, any interlock requirement, other suspensions on your record, and DMV approval — and the timing rules differ by situation, so we confirm your exact eligibility window before filing. The application runs through WisDOT paperwork, an SR-22 filing from your insurer, and proof of interlock installation where ordered — we can help prepare and review the application and supporting filings.

Is refusing the test better than failing it?

They are two different problems, not a loophole and a trap. Refusal is a stand-alone violation: a first refusal brings a 1-year license revocation, a mandatory alcohol assessment, and a mandatory 1-year ignition interlock — and the refusal itself can be used as evidence against you in the OWI case. Failing the evidentiary chemical test — the breath, blood, or urine test after arrest, not the roadside preliminary breath test — instead triggers a 6-month administrative suspension. Either way, the clock is the same: 10 days to request a refusal hearing or administrative review, or the license consequence takes effect on its own 30 days after the notice is issued. Which situation you are in changes the strategy — it does not change the urgency.

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.
