For drivers 21 and older, the legal limit is 0.08% BAC. Commercial drivers face a 0.04% limit. Drivers under 21 are subject to Wisconsin's zero-tolerance law — any detectable alcohol can result in penalties.
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.
