The DWI Law in Minnesota
In Minnesota the offense is DWI, and the limit is 0.08.
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 St. Peter
The Nicollet County Sheriff's Office and the agency that reports for St. Peter (filed by the FBI as St. Peter Police Department) make the DWI arrests in and around St. Peter.
Together, the three agencies in Nicollet County with all twelve months of 2025 on file reported 421 arrests to the FBI that year, all offenses together; the FBI's count for Nicollet County does not break DWI out.
The Mankato Police Department is listed by the FBI across two counties including Nicollet County, so its arrests are not broken out for Nicollet County here.

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.
