Short answer: yes. Minnesota law calls for mandatory minimum sentences in specific situations involving drunk driving charges. But with proper legal representation, it may be possible to significantly reduce the negative consequences.
Minnesota's drunk driving statutes use a complex array of aggravating factors that may be used to enhance a charge for allegedly driving while impaired to a higher level of offense. Typically, a first-time offender is charged with a misdemeanor. However, a first-time offender may be charged with third-degree DWI if law enforcement or prosecutors allege that an aggravating factor was present at the time of the offense; a third-degree offense is a gross misdemeanor.
