The OWI Law in Wisconsin
In Wisconsin the offense is OWI, and the limit is 0.08.
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 Dunn County
The Dunn County Sheriff's Office and the agencies that report for Menomonie, Colfax, Boyceville and Elk Mound make the OWI arrests in Dunn County.
The FBI's agency list also places one more agency in Dunn County: the University of Wisconsin at Stout (campus police).
Together, the three agencies in Dunn County with all twelve months of 2025 on file reported 916 arrests to the FBI that year, all offenses together; the FBI's count for Dunn County does not break OWI out.

The License Case
The court case is only half the record. The Division of Motor Vehicles runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the Wisconsin Division of Motor Vehicles keeps the driving record the conviction goes on.
The Records an OWI Leaves
- The arrest report: from the agency that made the arrest, under the Wisconsin Public Records Law.
- The court file: from the Dunn County Circuit Court, kept by the Clerk of Circuit Court.
- The driving record: from the Wisconsin Division of Motor Vehicles.
