DeForest, Wisconsin, in Dane County, has about 12,000 residents (2024 Census Bureau estimate). An OWI arrest in DeForest starts two cases, a criminal case in the Dane County Circuit Court and a license case before the Division of Motor Vehicles, and leaves three records.

This guide covers the law, the arrest, booking, the court case, the license case, the records and common questions.

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 DeForest
The Dane County Sheriff's Office and the agency that reports for DeForest (filed by the FBI as Deforest Police Department) make the OWI arrests in and around DeForest.
The FBI's agency list also places these agencies in Dane County: the University of Wisconsin at Madison (campus police); the Capitol Police (state agency).
Together, the 17 agencies in Dane County with all twelve months of 2025 on file reported 15,821 arrests to the FBI that year, all offenses together; the FBI's count for Dane County does not break OWI out.
The Edgerton Police Department is listed by the FBI across two counties including Dane County, so its arrests are not broken out for Dane County here.

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 Dane County Circuit Court, kept by the Clerk of Circuit Court.
