An OWI arrest in Menomonee Falls starts two separate clocks the moment you drive away from the scene. One is on your license. If you refused the evidentiary test, you have 10 days from the Notice of Intent to Revoke to request a refusal hearing — let that window pass and the revocation runs on its own. If you failed the test, you have 10 days from the Notice of Intent to Suspend to request administrative review — let that window pass and the 6-month administrative suspension takes effect on its own, 30 days after the Notice of Intent to Suspend is issued. The other clock runs on your case in court. 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 Menomonee Falls and Waukesha County. We work from our Middleton office and appear where these cases are decided, including the Waukesha County Circuit Court.

OWI Attorneys in Menomonee Falls, WI

Attorney Stephen E. Mays has practiced law in Wisconsin since 1995. He is a former prosecutor with the Dane County District Attorney’s office, has litigated OWI cases at the municipal, circuit, appellate, and Wisconsin Supreme Court levels, and is a former member of the National College for DUI Defense. That courtroom background matters in a village like Menomonee Falls, where an OWI stop can come from any agency working these roads — city police, sheriff’s deputies, or the Wisconsin State Patrol — and where the charge can land in either a municipal court or the county circuit court depending on how it is written. Knowing which agency made the stop, and where the citation will be filed, shapes the defense from the first day.

An OWI lawyer earns the fee in the details — whether the stop was lawful, whether the field sobriety tests actually show what the officer claims, whether the chemical test held up, and whether every deadline that protects your license was met. Those are the questions a case needs answered from the start. We take them up at the first call.

When to Call Our Menomonee Falls, WI OWI Lawyers

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

• You received 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 — miss the window and the revocation runs on autopilot, and you lose the statutory chance to contest it.
• You took the test and the result was over the limit. That produces a Notice of Intent to Suspend, and you have 10 days from it to request administrative review — otherwise the administrative suspension takes effect 30 days after the Notice of Intent to Suspend 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 falls within the past 10 years. A third runs 45 days to a year, and from there every qualifying prior in your lifetime counts.
• 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 personal vehicle — disqualifies your commercial privileges for a year, and a second lifetime conviction ends them permanently.
• 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 prosecutes drunk driving as OWI — DUI and DWI are the search terms, not separate charges. (A single stop can also produce a companion PAC count for the alcohol concentration itself; a driver found guilty of both is sentenced on one conviction.) Penalties climb with each prior:

• First offense. Civil forfeiture, not a crime. $150–$300, plus the mandatory $435 surcharge. No jail. License revoked 6–9 months. A civil first offense may be handled in either municipal or circuit court, depending on the citing agency — and in municipal court the village need only prove the violation by “clear, satisfactory and convincing” evidence under § 800.08(3), a lower bar than the criminal standard.
• Second offense. Criminal misdemeanor if the prior happened within 10 years. Jail: 5 days to 6 months.
• Third offense. Jail: 45 days to 1 year. From here on, priors count for life — earlier OWIs, refusal revocations, OWI-related injury convictions, and qualifying out-of-state convictions all come back into play.
• Fourth offense. Class H felony. 60 days to 6 years of imprisonment.
• Minor under 16 in the car. Even a first offense becomes a criminal misdemeanor: a $350–$1,100 fine and 5 days–6 months in jail.
• Ignition interlock. Required in three situations only: a test refusal, a first offense with a BAC of 0.15 or higher, or a repeat offense.
• Your license. Revocation accompanies every conviction. An occupational license can cover work, school, and treatment driving — but eligibility is not automatic. It depends on your suspension type, interlock status, the rest of your driving record, and DMV approval.
• Deadlines. Refused the evidentiary test? 10 days from the Notice of Intent to Revoke to request a refusal hearing. Failed it (the station breath or blood test, not the roadside PBT)? 10 days from the Notice of Intent to Suspend to request administrative review.

Miss a deadline and the license consequences run on their own — the administrative suspension takes effect 30 days after the Notice of Intent to Suspend is issued.

One more line on the counting. An under-21 conviction under § 346.63(2m) — Wisconsin’s absolute-sobriety rule for drivers under 21 — is not itself a countable prior under § 343.307, so it does not, on its own, push a later adult OWI up the penalty ladder.

The Real Cost of an OWI

The citation shows one number. The real bill has several:

• $435 — mandatory OWI surcharge on every conviction.
• $165–$500 — the required alcohol and drug assessment (varies by county).
• $50–$150 to install, $60–$100 per month — ignition interlock, if one is ordered.
• $200 — license reinstatement fee.
• Years of SR-22 high-risk insurance premiums stacked on top.

A typical first offense totals $4,000 to over $10,000 all-in. Every figure above is a typical range — your county, your vendor, and your insurer set the actual numbers, so treat these as planning estimates rather than a quote. Weigh the cost of a defense against that full total before deciding to simply pay and plead through. A free consultation costs nothing: 608-305-4518.

How OWI Cases Move Through Waukesha County Courts

Where a Menomonee Falls OWI is heard depends on how it is charged. A civil first-offense OWI is not automatically routed one way: depending on the agency that issued the citation, it may be filed in a municipal court or in the Waukesha County Circuit Court, and any contested hearing runs before that court. In a municipal proceeding, the standard of proof is “clear, satisfactory and convincing” evidence under § 800.08(3) — still a real burden the prosecution must carry, and one worth testing.

Every criminal OWI — a repeat offense, or a first offense involving a minor passenger or injury — is filed in the Waukesha County Circuit Court at 515 W Moreland Blvd in Waukesha, one of the busier court systems in the state with 12 circuit court branches. 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 assembled, 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 proceeds to trial, where the State must prove guilt beyond a reasonable doubt.

How We Defend OWI Charges

Prosecutors must build an OWI case in layers. Defending one means testing every layer:

• The stop. Reasonable suspicion is required to stop you. Probable cause is required to arrest you. A defect in either may support a motion to suppress the resulting evidence.
• Field sobriety tests. The three standardized tests are error-prone. The validation research excluded people 65 and older and those 50 or more pounds overweight. Arthritis, inner-ear problems, leg injuries, cold, wind, wet pavement, footwear — each can produce false “clues.”
• The breath number. For most drivers 0.08 is the line — drivers behind the wheel of a commercial vehicle, under-21 drivers, drivers under an interlock order, and anyone with three or more priors face stricter limits — and close readings invite challenge. Chemical-test reliability is a core defense front, and after you take the agency’s primary test you can request its alternative test free of charge, or arrange your own testing at your own expense.
• The blood draw. Drawing blood is a Fourth Amendment search. In State v. Prado (2021), the Wisconsin Supreme Court struck down the presumption that an incapacitated driver consents. Exceptions like exigent circumstances can still justify a draw, but a warrantless draw without valid consent faces serious scrutiny.
• The operation element. The State must prove you operated the vehicle — physically manipulated or activated the controls needed to put it in motion. Parked-car and sleeping-driver cases often turn on this element.
• The license track. Refusal hearings and administrative reviews run parallel to the main case. Both carry 10-day request windows.

No single defense fits every arrest. The right one comes out of your reports, your video, and your facts — 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.

Menomonee Falls 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 Menomonee Falls OWI case actually be heard?

It depends on how the charge is written. A civil first offense is not routed one way automatically — depending on the agency that issued the citation, it may be handled in a municipal court or in the Waukesha County Circuit Court, where the prosecution’s burden in a municipal proceeding is “clear, satisfactory and convincing” evidence under § 800.08(3). Any criminal OWI — a repeat offense, or a first offense with a minor passenger or injury — is filed in the Waukesha County Circuit Court at 515 W Moreland Blvd in Waukesha. So whether your stop came from Village police, the Waukesha County Sheriff, or a State Patrol trooper, the criminal cases converge on the same county courthouse.

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.

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.

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 urgency is the same: 10 days to request a refusal hearing from the Notice of Intent to Revoke, or administrative review from the Notice of Intent to Suspend. Which situation you are in changes the strategy — it does not change the deadline.
