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.

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.
