Beloit, Wisconsin, in Rock County, has about 37,000 residents (2024 Census Bureau estimate). An OWI arrest in Beloit starts two cases, a criminal case in the Rock County Circuit Court and a license case before the Division of Motor Vehicles, and leaves three records. This guide follows the arrest from the roadside to the court file and the driving record.
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 Beloit
The Rock County Sheriff's Office and the agency that reports for Beloit (filed by the FBI as Beloit Town Police Department) make the OWI arrests in and around Beloit.
Together, the six agencies in Rock County with all twelve months of 2025 on file reported 5,739 arrests to the FBI that year, all offenses together; the FBI's count for Rock County does not break OWI out.
The Brodhead Police Department is listed by the FBI across two counties including Rock County, so its arrests are not broken out for Rock County here.
Booking After an OWI Arrest in Beloit

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