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 Iowa County
The Iowa County Sheriff's Office and the agencies that report for Dodgeville, Mineral Point, Barneveld, Highland, Avoca and Linden make the OWI arrests in Iowa County.
Together, the four agencies in Iowa County with all twelve months of 2025 on file reported 297 arrests to the FBI that year, all offenses together; the FBI's count for Iowa County does not break OWI out.
The Muscoda Police Department and the Blanchardville Police Department are each listed by the FBI across several counties including Iowa County, so their arrests are not broken out for Iowa County here.
