Understanding Wisconsin DUI/OWI Laws

Wisconsin treats drunk driving offenses seriously, with penalties that become increasingly severe with each conviction. The state refers to these offenses as “Operating While Intoxicated” (OWI), though many people use DUI and OWI interchangeably. Under Wisconsin law, these are violations of the OWI statutes:

Blood alcohol concentration at or above 0.08 percent: This standard applies to most drivers aged 21 and over.
Operating under the influence of intoxicants: These include alcohol, prescription medications, controlled substances, or other drugs that affect your ability to drive safely.
Presence of restricted substances: Having any detectable amount of certain controlled substances in your bloodstream can lead to OWI charges regardless of impairment.
Commercial driver limits: Commercial drivers face stricter standards with a legal limit of 0.04 percent
Underage drinking and driving: For drivers under 21, Wisconsin maintains a zero-tolerance policy with a 0.00 percent BAC limit.

Consequences of a DUI/OWI Conviction in Wisconsin

Even first-time OWI offenses carry significant penalties in Wisconsin. Without proper legal representation from a DUI attorney, you risk:

License suspension: Losing your driving privileges affects your ability to work, attend school, and fulfill family responsibilities.
Substantial fines: Financial penalties range from hundreds to thousands of dollars depending on the offense level.
Mandatory alcohol assessments: Courts often require evaluation and potential treatment programs at your expense.
Ignition interlock device: Many convictions require the installation of this device, which prevents your vehicle from starting without a clean breath sample.
Insurance rate increases: Your auto insurance premiums will likely rise substantially following a conviction.
Criminal record: A OWI offense creates a permanent criminal record that can hinder employment and housing opportunities.
Potential jail time: You may face incarceration depending on circumstances and prior convictions.

For repeat offenders, these penalties escalate dramatically with each subsequent drunk driving conviction, including mandatory minimum jail sentences, longer license revocations, and higher fines. As such, if you already have a prior DUI conviction, it is even more essential to seek the assistance of an experienced Wisconsin OWI attorney.

Waukesha DUI/OWI Defense Strategies

Attorney John Paul Marchan develops drunk driving defense strategies to address each case’s specific circumstances. With his extensive trial experience and deep knowledge of Wisconsin DUI/OWI law, our DUI attorney will examine every aspect of your case, including:

Traffic stop legality: Police officers must have reasonable suspicion to initiate a traffic stop. Challenging this element can sometimes lead to case dismissal.
Field sobriety test administration: These tests must follow specific protocols to be considered valid. Improper administration may render results inadmissible.
Breathalyzer accuracy: Breath testing devices require proper calibration and maintenance. Attorney Marchan can scrutinize maintenance records and testing procedures for potential flaws.
Blood test procedures: Blood samples must be properly collected, stored, and analyzed. Chain of custody issues or improper handling can compromise results.
Officer conduct: Any violations of your constitutional rights during the arrest process may provide grounds for challenging the charges.
Medical conditions: Certain medical conditions can mimic intoxication or affect test results. These factors must be considered in your defense.
Alternative explanations: Fatigue, allergies, or other factors can cause symptoms similar to intoxication and may explain an officer’s observations.

Born and raised in Waukesha, criminal defense attorney Marchan uses his local connections and courtroom experience to fight for the best possible outcomes for his clients. His track record includes numerous not-guilty verdicts from twelve-person juries in both Waukesha and Milwaukee counties.

What to Do If Charged with DUI/OWI

If police arrest you for DUI/OWI in Wisconsin, taking the following actions can help protect your rights:

Exercise your right to remain silent: Beyond providing basic identifying information, you have the right to decline to answer questions without an attorney present.
Contact a DUI attorney immediately: DUI cases move quickly, with administrative deadlines that begin immediately after arrest. Early intervention by Attorney Marchan can preserve important legal options.
Document everything you remember: Write down all details of your arrest while events remain fresh in your memory, including officer statements, testing procedures, and your activities before the arrest.
Attend all court appearances: Missing court dates can result in additional charges and complicate your defense.
Request a DMV hearing promptly: You typically have only 10 days after arrest to request a hearing to contest the suspension of your license. Attorney Marchan can handle this process for you.
Follow all release conditions: Comply with any temporary restrictions or requirements to avoid additional legal complications.
