The DWI Law in Minnesota
Drunk driving is charged as DWI in Minnesota, at a blood alcohol level of 0.08 or more.
Driving in Minnesota is consent to a breath or blood test when an officer has cause to suspect DWI; the license case that follows a refusal or a failed test is run by Driver and Vehicle Services, separately from the criminal case.
For charging and sentencing, Minnesota counts prior offenses within 10 years.
Who Makes DWI Arrests in Martin County
The Martin County Sheriff's Office and the agencies that report for Fairmont, Sherburn and Trimont make the DWI arrests in Martin County.
Together, the four agencies in Martin County with all twelve months of 2024 on file reported 331 arrests to the FBI that year, all offenses together; the FBI's count for Martin County does not break DWI out.

The License Case
The court case is only half the record. Driver and Vehicle Services runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the Minnesota Driver and Vehicle Services keeps the driving record the conviction goes on.
The Records a DWI Leaves
- The arrest report: from the agency that made the arrest, under the Minnesota Government Data Practices Act.
