Overview

Minnesota uses the term DWI (Driving While Impaired) and operates a unique dual-track system where administrative (license) and criminal penalties run independently. The state's implied consent law is among the strongest in the nation — refusing a chemical test is itself a crime carrying the same penalties as a DWI conviction. Minnesota classifies DWI offenses into four degrees (1st through 4th), with 1st degree being the most serious. A first-degree DWI — a fourth offense within 10 years, any DWI after a prior felony DWI conviction, or any DWI after a prior felony criminal vehicular operation conviction — is a felony carrying up to 7 years in prison with a mandatory 3-year prison sentence. The state also has a unique 'whiskey plates' program that requires special registration plates for repeat offenders and high-BAC cases.

Stat. § 169A.275)Up to $3,000License canceled as inimical to public safety (three or more impaired-driving incidents within 10 years); reinstatement only through the ignition interlock programRequired for reinstatement and for any driving during the revocation
Felony1st Degree DWI — FelonyUp to 7 years in state prison with a mandatory minimum 3-year prison sentence (Minn.

Driving on a license canceled as inimical to public safety is a separate offense under § 171.24 (gross misdemeanor; a felony after a prior § 171.24 conviction), not a felony upgrade of the DWI itself. Lookback period: 10 years.

Implied Consent Law

Under Minnesota's implied consent law (Minn. Stat. §169A.51), operating a motor vehicle in Minnesota constitutes consent to chemical testing. Critically, refusing a chemical test in Minnesota is itself a crime — not merely an administrative penalty. The Minnesota Supreme Court upheld criminal penalties for breath test refusal (but not blood test refusal without a warrant) following the Birchfield v. North Dakota (2016) framework.

Refusal penalties: Test refusal is a crime carrying the same penalties as the underlying DWI charge (up to gross misdemeanor or felony depending on circumstances). Administrative penalties: 1-year license revocation for first refusal. Refusal with aggravating factors (prior DWI, high BAC): 2+ year revocation. Vehicle forfeiture may also apply. Refusal elevates the offense degree (e.g., a first-offense refusal is treated as a 3rd degree gross misdemeanor rather than a 4th degree misdemeanor).

Aggravating Factors

FactorImpact
BAC of 0.16% or higherElevates offense degree by one level; mandatory IID; 'whiskey plates' required on all vehicles owned or operated by the offender
Prior DWI within 10 yearsEach prior conviction elevates the offense degree; 4th offense within 10 years is a felony with up to 7 years prison
Child under 16 in the vehicleElevates offense degree by one level; potential separate child endangerment charges
Chemical test refusalRefusal is a separate crime carrying same penalties as DWI; elevates offense degree; longer license revocation
Driving with a canceled license (inimical to public safety)Not a DWI degree factor: driving after cancellation (inimical) is a separate gross misdemeanor under Minn. Stat. § 171.24 (up to 1 year and $3,000; a felony after a prior § 171.24 conviction)
Causing great bodily harm or deathCriminal vehicular homicide (Minn. Stat. § 609.2112): up to 10 years imprisonment and $20,000; criminal vehicular operation causing great bodily harm (§ 609.2113): up to 5 years; substantial bodily harm: up to 3 years

DUI with Injury

Classification: Felony — Criminal Vehicular Operation / Criminal Vehicular Homicide

Criminal vehicular operation causing great bodily harm (Minn. Stat. § 609.2113, subd. 1): up to 5 years imprisonment and a $10,000 fine; causing substantial bodily harm (subd. 2): up to 3 years and $10,000; causing bodily harm (subd. 3): gross misdemeanor, up to 364 days and $3,000. Criminal vehicular homicide (§ 609.2112): up to 10 years imprisonment and a $20,000 fine.

Underage DUI

Zero tolerance: Yes
BAC limit: 0.00% (any amount)

Minnesota has a true zero-tolerance law for drivers under 21. Any detectable amount of alcohol triggers administrative action: first offense — 30-day license withdrawal. Second offense — 180-day withdrawal. These are administrative sanctions separate from any criminal DWI charges. If the underage driver's BAC is 0.08%+, full criminal DWI charges and penalties apply in addition to the zero-tolerance administrative action.

Diversion Programs

Program: DWI Court / Ignition Interlock Program

Minnesota operates DWI Courts in many counties that provide treatment-focused supervision for repeat offenders as an alternative to extended incarceration. The state also offers a broader Ignition Interlock Program that allows offenders to drive with an IID during their revocation period. Some counties offer diversion or stay-of-adjudication agreements for first-time offenders where the charge may be reduced or dismissed upon successful completion of conditions.

Eligibility: DWI Court is typically available for repeat offenders (2nd or 3rd degree) who demonstrate a substance use disorder and are willing to commit to intensive supervision. Stay-of-adjudication may be available for first-time offenders in some counties at the prosecutor's discretion. Offenses involving injury, death, or extremely high BAC may be excluded.

How Long a DUI Stays on Your Record

A DWI conviction remains on your Minnesota criminal record permanently. Minnesota allows expungement of certain criminal records, but DWI convictions are very difficult to expunge — courts consider the public safety implications and generally deny DWI expungement requests. For driving record and lookback purposes, DWI convictions count for 10 years. A DWI typically affects insurance rates for 5–10 years.

Frequently Asked Questions

What is the penalty for a first DWI in Minnesota?
A basic first-offense DWI in Minnesota is a 4th degree misdemeanor carrying up to 90 days in jail, up to $1,000 fine, and a 90-day license suspension (30 days hard, 60 days restricted). However, if your BAC was 0.16% or higher or you refused the test, the offense is elevated to a 3rd degree gross misdemeanor with up to 1 year in jail and $3,000 fine.
Is it a crime to refuse a breathalyzer in Minnesota?
Yes — Minnesota is one of the few states where refusing a chemical test is itself a criminal offense, not just an administrative penalty. Refusal carries the same criminal penalties as a DWI conviction and elevates the offense degree. For example, a first-offense refusal is treated as a 3rd degree gross misdemeanor (up to 1 year jail, $3,000 fine) rather than a 4th degree misdemeanor.
What are whiskey plates in Minnesota?
Whiskey plates (also called W plates or special registration plates starting with the letter W) are required for vehicles owned or driven by certain DWI offenders. They are required when BAC is 0.16%+, for repeat offenders, for test refusals, or after vehicle forfeiture. Law enforcement can stop vehicles with whiskey plates to verify the driver is licensed, making them a powerful enforcement tool.
When does a DWI become a felony in Minnesota?
A DWI becomes a first-degree felony on a 4th offense within 10 years, after any prior felony DWI conviction, or after a prior felony criminal vehicular operation conviction — carrying up to 7 years in prison and a $14,000 fine, with a mandatory minimum 3-year prison sentence (Minn. Stat. § 169A.24, 169A.276). Driving while your license is canceled as inimical to public safety is a separate crime (§ 171.24), not a felony upgrade of the DWI itself. DWI causing death (criminal vehicular homicide, § 609.2112) is a felony with up to 10 years.
How long does a DWI stay on your record in Minnesota?
A DWI conviction stays on your Minnesota criminal record permanently. The conviction counts within the 10-year lookback period for determining whether future offenses are elevated to higher degrees. Expungement of DWI convictions is technically possible but rarely granted by Minnesota courts due to public safety concerns.
What is the lookback period for DWI in Minnesota?
Minnesota uses a 10-year lookback period. Prior DWI convictions (including those from other states) within the past 10 years count when determining the degree of your current offense. Each prior conviction elevates the degree: 1 prior = 3rd degree, 2 priors = 2nd degree, 3+ priors = 1st degree felony.
Can you get a restricted license after a DWI in Minnesota?
Yes. Minnesota's Ignition Interlock Program allows most DWI offenders to drive during their revocation period with an IID-equipped vehicle. For a first offense, you may be eligible for a restricted license after 15 days. For repeat offenses, the waiting period is longer. You must enroll in the IID program, maintain the device, and comply with all conditions.
What happens if you get a DWI under 21 in Minnesota?
Minnesota has zero tolerance for underage drinking and driving. Any detectable alcohol for drivers under 21 triggers a 30-day license withdrawal (first offense) or 180 days (second offense). If your BAC is 0.08%+, you face full criminal DWI charges with the same penalties as adult offenders, plus the administrative zero-tolerance sanctions.
