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.
