An OWI arrest in Onalaska starts two clocks at the same time. One runs against your license: whether you refused the test or failed it, you generally have just 10 days from your notice to request a hearing or review — and if you let that window pass, the license consequence takes effect on its own 30 days after the notice is issued. The other runs against your case in court. Mays Law Office defends OWI charges — the offense most people search as DUI or DWI, though Wisconsin’s statutory charge is OWI — along with drugged-driving allegations, throughout Onalaska and La Crosse County. Mays Law Office represents clients across Wisconsin from our office in Middleton — including Onalaska and La Crosse County.

OWI Attorneys in Onalaska, 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. Onalaska sits on the Mississippi River as the commercial anchor of the La Crosse metro area, which means the road that carried you home may be watched by more than one agency — and the agency that writes the citation can shape the reports, the video, and where the charge lands. Those are the questions a case needs answered from the start.

An OWI lawyer earns the 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. We start on those questions at the first call.

When to Call Our Onalaska, 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 from that notice to request a refusal hearing in writing — let the window close and the revocation takes effect on its own, and you forfeit the statutory chance to contest it.
• You took the test and the result came back over the limit. That triggers a Notice of Intent to Suspend, and you have 10 days from it 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 generally becomes a criminal misdemeanor when the prior falls within the last 10 years, carrying 5 days to 6 months in jail. A third runs 45 days to a year and is criminal regardless of age. 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

What actually happens if you’re convicted of OWI in Wisconsin? (And yes — if you searched “DUI” or “DWI,” this is your answer; Wisconsin’s statute calls the offense OWI, whichever name you typed.) It depends on which offense number this is. First time, with no aggravating facts? You’re facing a civil forfeiture — $150 to $300 plus the $435 mandatory surcharge — a 6-to-9-month license revocation, and no jail. Second time? If the prior was within 10 years, it’s now a crime, with 5 days to 6 months in jail. Third? 45 days to a year — and from the third offense onward, every prior you’ve ever had counts, with no time limit. Fourth? That’s a Class H felony: 60 days to 6 years of imprisonment. Was a child under 16 riding with you? Then even a first offense is a criminal misdemeanor — a $350–$1,100 fine plus mandatory jail of 5 days to 6 months. Will you need an ignition interlock? Only in defined situations: a refusal, a first offense at a BAC of 0.15 or higher, or a repeat offense. Can you keep driving to work? Possibly, on an occupational license — but don’t assume it; eligibility turns on your suspension type, any interlock requirement, the rest of your record, and DMV sign-off. And how long do you have to act? Ten days — to request a refusal hearing if you declined the test, or administrative review if you failed the evidentiary chemical test.

What does an OWI really cost? More than the fine — usually much more. Every OWI conviction carries a mandatory $435 surcharge. The required alcohol and drug assessment typically costs $165 to $500. If the court orders an ignition interlock, expect around $50 to $150 to install it and $60 to $100 per month to keep it running. Reinstating your license adds another $200. Then SR-22 high-risk insurance inflates your premiums for years. Where does that leave a typical first offense? Somewhere between $4,000 and beyond $10,000 all told — and those are typical ranges that shift with your county, your vendor, and your insurer. Measured against that total, a serious defense review is inexpensive, and ours is free: 608-305-4518.

How OWI Cases Move Through Onalaska and La Crosse County Courts

Where an Onalaska OWI is heard depends on what it is charged as. A standard civil first-offense OWI — a non-criminal forfeiture — may be handled in a municipal court or in the circuit court, depending on which agency issued the citation; that routing is not automatic and is worth confirming early. In a municipal proceeding the government’s burden is “clear, satisfactory and convincing” evidence under Wis. Stat. § 800.08(3), a different standard than the criminal one. Any criminal OWI — a repeat offense, or a first offense involving a minor passenger or injury — is filed in the La Crosse County Circuit Court, which sits at 333 Vine Street in La Crosse and runs five branches, and is prosecuted by the District Attorney’s Office.

Because Onalaska is a river-metro hub tied to the wider La Crosse area, an OWI stop can come from more than one agency, and which agency stopped you can affect the reports, the video, and how the case is built — 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

Is there any point in fighting an OWI charge? Often, yes — because the State’s case has to survive five separate questions. Was the stop legal? Police need reasonable suspicion before pulling you over and probable cause before arresting you; a defect in either can suppress what followed. Do the field tests prove impairment? Not reliably — the standardized battery was validated on limited populations, and medical conditions, age, weight, injuries, weather, and footwear routinely mimic intoxication in sober people. Is the breath result airtight? A reading near the applicable limit — 0.08 for most drivers — is worth pressing: the reliability of chemical testing is a recognized battleground, and once you take the agency’s primary test, you’re entitled to its alternative test free of charge — or a test of your own choosing at your own expense. Was the blood draw constitutional? Taking blood is a Fourth Amendment search, and after State v. Prado (2021) — which struck down the presumption that an incapacitated driver consents — a warrantless draw without valid consent faces genuine challenge (though the State can invoke exceptions like exigent circumstances, so the analysis is fact-specific). Did you even “operate” the vehicle? Wisconsin defines operation as physically manipulating or activating the controls needed to put the car in motion, and whether that happened is a factual question the State must prove. None of these defenses is guaranteed to win, and not all of them will apply to you. The point of a case review is finding out which ones do. That review is free — 608-305-4518.

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.

Onalaska 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 Onalaska OWI case actually be heard?

That depends on how it is charged. A standard civil first offense may be handled in a municipal court or in the La Crosse County Circuit Court, depending on which agency issued the citation — the routing is not automatic, and in a municipal proceeding the burden of proof is “clear, satisfactory and convincing” evidence rather than the criminal standard. Any criminal OWI — a repeat offense, or a first offense with a minor passenger or injury — is filed in the La Crosse County Circuit Court at 333 Vine Street in La Crosse, which runs five branches, and prosecuted there by the District Attorney. Confirming which track your case is on is one of the first things we do.

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.

Is a lawyer really worth it for a civil first offense?

The first offense is where the record starts. It cannot be expunged, it raises your insurance for years, it disqualifies commercial driving privileges for a year if you hold a CDL, and it sets the counting clock — a second OWI within 10 years is generally a crime, and priors count forever once you reach a third. One note that surprises people: an under-21 “absolute sobriety” citation under § 346.63(2m) is not itself a countable prior under § 343.307. Challenging a weak stop or an unreliable test is often the cheapest insurance you will ever buy.
