Wisconsin uses the term OWI (Operating While Intoxicated). Other states may say DUI or DWI, but Wisconsin law refers to operating a motor vehicle while impaired by alcohol, drugs, or other substances.
You can refuse, but Wisconsin's implied consent law means refusal typically results in an automatic license revocation and may be used as evidence in court. Refusal penalties are separate from OWI penalties.
Total costs often exceed $10,000 when you include fines, legal fees, increased insurance, license reinstatement, and ignition interlock. Exact amounts depend on offense number and circumstances.
Yes. The Tavern League of Wisconsin SafeRide program provides free rides home from participating TLW-member taverns statewide. Learn more at tlw.org/saferide or use the TLW SafeRide mobile app at tlw.org/saferide-app to find nearby providers. Availability varies by establishment — ask your bartender. Local county resources are also listed on this site.
The SAMHSA National Helpline (1-800-662-4357) provides free, confidential referrals 24/7. Wisconsin DHS also maintains a directory of treatment providers by county.
Wisconsin generally does not allow expungement of OWI convictions. An OWI remains on your driving record and can affect employment, insurance, and future penalties.
Offer a concrete alternative — call a ride, take their keys, or help them stay where they are. If they drive anyway and pose immediate danger, contact local law enforcement.
A first-offense OWI in Wisconsin is typically a civil violation with fines, license revocation, mandatory alcohol assessment, and possible ignition interlock depending on BAC. Penalties increase significantly for higher BAC levels and repeat offenses.
Wisconsin requires ignition interlock devices for repeat OWI offenders and for first offenses with a BAC of 0.15% or higher. Interlock must be installed on all vehicles registered to the offender.
Plan before you drink: designate a sober driver, save rideshare apps, check for Tavern League SafeRide at your venue, or use CrossroadsWI's Plan Your Ride guide. Having a plan before the first drink is the most reliable way to get home safely.
Wisconsin officially uses OWI (Operating While Intoxicated). DUI and DWI are common terms in other states and in everyday conversation, but Wisconsin statutes and court records use OWI.
