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 Cottage Grove
The Dane County Sheriff's Office and the agency that reports for Cottage Grove (filed by the FBI as Cottage Grove Police Department) make the OWI arrests in and around Cottage Grove.
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.
