The OWI Law in Wisconsin
Drunk driving is charged as OWI in Wisconsin, at a blood alcohol level of 0.08 or more.
Driving in Wisconsin is consent to a breath or blood test when an officer has cause to suspect OWI; the license case that follows a refusal or a failed test is run by the Division of Motor Vehicles, separately from the criminal case.
Wisconsin sets no time limit on prior offenses: every earlier conviction counts toward a repeat charge.
Who Makes OWI Arrests in Hartland
