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 Polk County
The Polk County Sheriff's Office and the agencies that report for East Grand Forks, Crookston and Fosston make the DWI arrests in Polk County.
