OWI Defense Lawyers in Wisconsin
Defending individuals charged with OWI and related impaired driving offenses throughout Wisconsin.
Operating While Intoxicated (OWI) in Wisconsin is not a single offense, but a category of impaired driving charges that can escalate quickly based on a person’s prior history, the type of impairment alleged, and the circumstances of the stop. OWI cases may involve alcohol, drugs, or a combination of both, and charges are often filed alongside related allegations arising from the same incident.
Wisconsin treats OWI cases with heightened scrutiny, and early charging decisions can significantly affect a person’s legal exposure. While some OWI cases are civil in nature, others carry criminal penalties, and repeat offenses can result in felony charges. Importantly, an arrest does not automatically result in a conviction, and many OWI cases turn on whether law enforcement and the State complied with constitutional and evidentiary requirements.
Because OWI cases often involve complex investigative issues and multiple legal tracks, early involvement by an experienced defense attorney is critical. Prompt legal guidance can help protect constitutional rights, identify weaknesses in the State’s evidence, and shape how the case proceeds from the outset.

The attorneys at Chirafisi Anderson, S.C. have extensive experience defending individuals charged with OWI and related impaired driving offenses in Wisconsin courts. Our practice focuses on identifying unlawful stops, challenging the reliability of field sobriety and chemical testing, and scrutinizing whether law enforcement and the State have met their legal and constitutional obligations. We approach OWI cases with a litigation mindset, recognizing that early investigation and strategic motion practice often determine the outcome.
Types of OWI Charges in Wisconsin
Wisconsin law recognizes multiple OWI-related charges, each governed by different legal standards and potential consequences. While these charges often arise from the same traffic stop or arrest, they are legally distinct and must be evaluated separately.

How OWI Cases Are Commonly Prosecuted in Wisconsin
OWI cases in Wisconsin typically begin with a traffic stop followed by an investigation into whether a driver was impaired. Law enforcement may rely on observations, field sobriety testing, and chemical testing to determine whether charges are warranted. Charging decisions are often made early and may involve multiple OWI-related allegations arising from the same incident.
In addition to the criminal case, OWI arrests frequently trigger separate administrative proceedings that operate on strict deadlines and independent legal standards. These parallel processes can affect driving privileges and other rights regardless of how the criminal case ultimately resolves. Early procedural decisions can therefore have significant consequences.
Because OWI prosecutions often hinge on the legality of the stop, the conduct of the investigation, and the reliability of testing, early involvement by an experienced defense attorney is critical. Prompt legal representation can help protect constitutional rights, challenge improper evidence, and ensure that the State’s case is thoroughly examined rather than assumed.
OWI-Related Legal and Administrative Issues
An OWI arrest often raises immediate questions beyond the criminal charge itself. Depending on the circumstances, individuals may be dealing with separate administrative proceedings, driving restrictions, or strategic defense considerations that operate on strict timelines.
