Question: How long has there been a drunk driving law in Minnesota?
Answer: The Minnesota Legislature criminalized DWI in 1911, making “driving while in an intoxicated manner” a misdemeanor. The laws and sanctions addressing DWI have certainly evolved in the past 103 years. The strengthened efforts are successfully working to get drunk drivers off the roads:
• Evidence of influence was set at .15 Blood Alcohol Concentration (BAC) in 1917.
– The first civil sanctions for DWI (Implied Consent) began in 1961.
• A per se level of .10 BAC was attached to administrative license sanctions in 1971 (MN was the first state to take such action).
• The concept of BAC changed to Alcohol Concentration (AC) in 1978.
• License plate impoundment began in 1988.
• Test refusal became a criminal offense in 1989.
• Child Endangerment enhancement and ‘Not a Drop’ law enacted in 1993.
• High AC (.20+) added as an enhancement in 1997.
• Felony level penalties established in 2001.
• Per se level lowered to .08 AC in 2004.
• Ignition Interlock added in 2010.
Minnesota’s enhanced DWI enforcement and education efforts are contributing to the reduction of alcohol-related deaths. Still, drunk driving remains a serious threat, with 279 drunk driving-related traffic deaths in Minnesota since 2011 and 25,719 motorists arrested for DWI last year. One in seven Minnesota drivers has a DWI on record. 
The legal limit for driving impaired in Minnesota is 0.08 — but motorists can be arrested for DWI at lower levels. The consequences for driving impaired will vary for each DWI offender. A typical penalty for a first-time offender is loss of license for a minimum of 30 days up to a year and possible jail time. DWI costs can be as high as $20,000 when factoring court costs, legal fees and increased insurance premiums.
