DUI Attorney in Mequon, WI

Ozaukee County DUI Defense Backed by Over 1,000 Case Dismissals

When Mequon residents face a DUI or OWI charge in Ozaukee County, the attorney they choose determines how aggressively it’s contested. At Melowski & Singh, LLC, we’ve defended clients against drunk driving charges across every Wisconsin county since 1993. Our published list of specific outcomes documents that record.

DUI defense is our only practice area. We treat every charge seriously and prepare each case as if it’s going to trial rather than pursuing a fast plea agreement.

Wisconsin OWI convictions can’t be expunged and stay on your record permanently. Consequences can include fines, loss of driving privileges, and jail time, with the severity increasing sharply for each subsequent offense. A conviction can follow you for life.

How Mequon DUI Charges Move Through the Courts

Mequon is located in Ozaukee County, Wisconsin. Non-criminal municipal citations may be handled by the Mid-Moraine Municipal Court, which serves multiple cities in Washington and Ozaukee Counties.

Criminal misdemeanor and felony OWI matters are prosecuted in Ozaukee County Circuit Court. We represent clients at both levels and understand how cases move through each venue.

Wisconsin’s implied consent law requires a driver lawfully arrested for OWI to submit to a chemical test. Refusal triggers separate administrative penalties, including revocation of driving privileges, in addition to any criminal proceedings.

What’s at Stake with a Wisconsin OWI Conviction

Wisconsin treats OWI offenses progressively. A first-offense OWI is classified as a civil forfeiture in most situations, but it increases the severity of any future charge.

A second offense and a third OWI offense are criminal charges. Confirmed Ozaukee County ranges for repeat misdemeanor cases include statutory confinement beginning at five days for a second offense and extending up to one year for a third offense, depending on the offense. From the third conviction onward, Wisconsin has no 10-year lookback limit for prior OWI convictions.

Beyond criminal penalties, a conviction can affect work that requires a commercial driver’s license or professional credential. The specific consequences depend on the driver’s record, the charge, and the requirements governing that credential. Wisconsin OWI convictions can’t be expunged. The record is permanent.

How We Build a Defense for Mequon OWI Cases

We look for the strongest available defense by examining each part of the arrest:

Whether the initial traffic stop was legally justified
How field sobriety tests were administered
Whether breathalyzer equipment was properly calibrated
How chemical-test evidence was handled from collection through the lab

Field sobriety tests can produce false positives. Environmental conditions and administration errors can undermine the reliability of the results. Blood and breath evidence may also be challenged based on machine calibration records, chain of custody, and laboratory procedures. A driver can be charged with OWI in Wisconsin even with a blood alcohol concentration below 0.08 if an officer asserts impairment, making the documentation surrounding the stop and testing critical to the defense.

We develop individualized strategies based on the specific facts of each client’s case, publish those results publicly, and prepare for trial in every matter we take on.

Peer Recognition in Wisconsin DUI Defense

Dennis Melowski has earned Wisconsin Super Lawyer recognition in DUI defense annually since 2005. In 2015, the Wisconsin Law Journal named him one of 30 Leaders in the Law statewide, selected from a bar of more than 15,000 attorneys. He was the only DUI defense attorney to receive that honor in the award’s 12-year history at the time.

His accolades include recognition as one of the Top 100 Trial Lawyers in Wisconsin by the National Trial Lawyers since 2007. Newsweek profiled him as one of eight leading criminal defense attorneys in the country in November 2011 and as a leading trial attorney in November 2012. Forbes Magazine’s Best in Business edition featured Melowski & Singh, LLC in September 2008 as the only law firm selected in the Milwaukee area.

Sarvan Singh has appeared on the Wisconsin Rising Stars list multiple times. Together, their recognition reflects the firm’s standing among Wisconsin peers in DUI defense.

First-Offense OWI in Mequon: Why It Warrants a Real Defense

A first-offense OWI in Wisconsin is classified as a civil forfeiture in most situations, but its effects are lasting. The conviction appears on your record permanently, can’t be expunged, and can increase the consequences of every subsequent OWI. Penalties and escalation factors include:

A $150 to $300 fine plus surcharges
Six to nine months of license revocation
A mandatory alcohol and drug assessment
Criminal charges if a passenger under 16 was in the vehicle or the incident caused injury

We handle first-offense OWI cases for clients throughout Mequon and Ozaukee County and have achieved dismissals and reductions to non-alcohol-related charges in first-offense matters across Wisconsin.

Second, Third & Felony OWI: Escalating Consequences

Repeat OWI charges carry consequences that compound significantly. In Ozaukee County, second-offense misdemeanor cases carry statutory confinement ranges beginning at five days and extending through six months, while third-offense cases range from 45 days to one year. From a third conviction forward, every prior OWI on your record counts, regardless of when it occurred. A fourth or subsequent OWI is a felony in Wisconsin. A fourth offense carries a statutory confinement range of 60 days to six years, while fourth-through-tenth offenses carry license revocation periods of 24 to 36 months. We handle repeat-offense and felony OWI defense for clients in Mequon and throughout the state, approaching these high-stakes cases with the same trial-ready preparation we bring to every matter.

Challenging Field Sobriety Tests & Chemical Evidence

The evidence in an OWI case is rarely as straightforward as the prosecution presents it. Field sobriety tests are standardized, but officer training, environmental conditions, and administration errors can affect the results and produce a false positive that leads to an arrest.

Breathalyzer and blood test results have their own vulnerabilities. Calibration records, blood-draw procedures, chain of custody, and laboratory handling can provide grounds for contesting the evidence’s reliability. Wisconsin’s implied consent law requires chemical testing after a lawful OWI arrest, but refusal triggers administrative penalties separate from any criminal charge, including license revocation and ignition interlock requirements. We handle test refusal cases and administrative suspension proceedings alongside criminal defense representation.

OWI Consequences for CDL Holders & Licensed Professionals

For Mequon residents who hold a commercial driver’s license or work in a regulated profession, an OWI allegation can affect their ability to continue work that requires a commercial license or professional credential. License-related consequences depend on the driver’s record, the charge, and the requirements governing the credential.

An ignition interlock device is required after certain convictions. It requires a clean breath test before the vehicle will start and logs all tests. We have a published category of case results specifically for CDL-related DUI matters, and we represent clients whose professional licenses are at risk alongside their criminal defense.
