In July 2011, Minnesota’s DWI and implied consent laws were changed for drivers who test 0.16 percent blood alcohol concentration or more. The higher alcohol level essentially extends the length of a license revocation associated with a DWI arrest. For instance, a first time DWI offender who measures 0.16 percent BAC or greater will have his or her driver’s license revoked for a full year. Drivers cannot obtain a work permit under the law, unless the driver agrees to have an ignition interlock device installed.
