Second-Degree DWI in Minnesota: Gross Misdemeanor Charges, Penalties & Defense Strategies
A second-degree DWI is the second most serious impaired driving charge in Minnesota — one step below a felony and one step above the charges most first-time offenders face. It’s classified as a gross misdemeanor, which means up to a year in jail, a $3,000 fine, and mandatory minimum sentences that courts cannot waive.
What surprises many people is how they end up with a second-degree charge. It doesn’t require three or four prior offenses. In some cases, a first-time DWI arrest with the wrong combination of circumstances is enough

What Makes a DWI Second-Degree in Minnesota
Under Minn. Stat. § 169A.25, a DWI is charged as second-degree when two or more aggravating factors were present at the time of the offense.
Minnesota law defines three aggravating factors:
A prior qualified impaired driving incident within the past 10 years (for criminal purposes) — this includes prior DWI convictions, prior license revocations for DWI, and prior implied consent violations
A BAC of 0.16% or higher — twice the legal limit
A child under age 16 in the vehicle who is more than 3 years younger than the driver
Two of these must be present for a second-degree charge. Here’s how the most common combinations play out:
The Most Common Scenarios

Prior DWI + high BAC
You had a DWI conviction 6 years ago, and you're arrested again with a BAC of 0.18%. Two aggravating factors: the prior incident and the elevated BAC. That's second-degree.

Prior DWI + child in car
You had a DWI revocation 4 years ago, and you're arrested with your 12-year-old in the passenger seat. Two aggravating factors. Second-degree.

High BAC + child in car
This is the scenario where a first-time offender can face second-degree charges. No prior record at all, but you blow a 0.17% with a child in the back seat. Two aggravating factors — second-degree gross misdemeanor, even though it's your first DWI.

Test refusal + one aggravating factor.
There's a separate path under § 169A.25(b): If you refuse the chemical test AND have just one other aggravating factor present, that's also second-degree. Refusing the test is treated more harshly because it carries its own statutory weight; the refusal, combined with any single aggravating factor, reaches the second-degree threshold.
What About the 20-Year Lookback?
An important distinction: for criminal charging purposes (determining the degree of DWI), the standard lookback for counting prior incidents is 10 years. The 20-year lookback under HF 2130 primarily affects the administrative side — license revocations, ignition interlock requirements, and plate impoundment. However, the administrative consequences of a second-degree charge are now significantly harsher because older priors count for those purposes. For a full breakdown of how these rules interact across all DWI degrees, see our Minnesota DWI laws complete guide.
Criminal Penalties for Second-Degree DWI

Maximum Jail Time
364 days
Maximum Fine
$3,000
Probation
Up to 4 years for a gross misdemeanor DWI
License Revocation
1-2 years (depends on BAC and prior record)
Mandatory Minimum Sentences
Second-degree DWI is subject to mandatory minimum sentences under § 169A.275 that the court cannot waive. The specific mandatory minimum depends on your prior record:
If you have one prior qualified incident within 10 years:
- Minimum 30 days of incarceration
- At least 48 hours must be served consecutively in a local jail
- The remaining 28 days can be served through community work service (8 hours per day) or on electronic home monitoring
- The court may allow up to 60 days of home detention
If you have two prior qualified incidents within 10 years
- Minimum 90 days of incarceration
- At least 30 days must be served consecutively in a local jail
- OR participation in an intensive DWI probation program (DWI Court) requiring at least 6 consecutive days in jail
If you have three or more prior qualified incidents within 10 years:
- Minimum 180 days of incarceration
- At least 30 days consecutive in jail
- OR participation in DWI Court with at least 6 consecutive days in jail

These mandatory minimums cannot be suspended or stayed. The court pronounces the full sentence (up to 365 days), stays the portion above the mandatory minimum, and places you on probation. If you violate probation, the stayed portion can be executed.
The 0.16% or Higher Penalty Enhancement
If your BAC was 0.16% or higher, additional consequences apply regardless of the degree. The court must order you to complete the level of treatment recommended in your substance use disorder assessment — and the court cannot ignore the assessment’s recommendations without stating reasons on the record. A penalty assessment of up to $1,000 can be added on top of the standard fine
Administrative Penalties (License, Plates, Vehicle)
The administrative penalties run parallel to the criminal case and are handled by the Department of Public Safety, not the courts. For second-degree DWI, these are substantial.
License Revocation
Situation
Revocation Period
Second offense within 10 years (BAC under 0.16%)
1 year
Second offense (BAC 0.16% or higher)
2 years
Second refusal
2 years
Third offense in 10 years or fourth ever
Canceled and denied for 6 to 10 years
Under the HF 2130 changes, if your prior DWI falls within the new 20-year administrative lookback — even if it’s outside the 10-year criminal lookback — your driver’s license penalties are significantly extended. A second DWI within 20 years now triggers a mandatory 2-year license revocation, meaning you are restricted to driving exclusively with an ignition interlock device for those 2 years. Additionally, you are strictly required to complete a licensed substance use disorder treatment program before you can successfully exit the interlock program and qualify for a standard, unrestricted license.

Plate Impoundment (Whiskey Plates)
Your standard license plates are confiscated and replaced with special 'W' plates—commonly called whiskey plates—which remain on vehicles registered in your name for at least one year. However, you can completely bypass or remove whiskey plates early by immediately enrolling in the state's Ignition Interlock Program and paying a $100 vehicle fee.

Vehicle Forfeiture
Vehicle forfeiture is an option for second-degree DWI, not an automatic consequence. The law allows for forfeiture upon a “designated license revocation,” which may include a second DWI if combined with certain enhancing factors. If you receive a notice of intent to forfeit, you have 60 days to challenge it. Don't miss this deadline.
Pretrial Release and Bail
Second-degree DWI carries more restrictive pretrial release conditions than lower-degree charges. The court can — and typically does — impose conditions including:
- Abstinence from alcohol and drugs
- Random testing (urinalysis, PBT, or REAM device)
- No driving without a valid license
- Surrender of passport (in some cases)
- Regular check-ins with pretrial services
For cases involving a BAC of 0.16% or higher, the court may require electronic alcohol monitoring (a REAM device or similar technology) as a condition of pretrial release. These devices continuously monitor your perspiration for alcohol and report any detected use to the court.
Violating pretrial release conditions is taken seriously. Note that, following recent statutory updates, your temporary driving permit given immediately upon arrest is now valid for 14 days (increased from 7 days), giving you exactly two weeks to file an administrative review challenge or set up interlock tracking to preserve your driving privileges.

Long-Term Monitoring
Under § 169A.277, the court can order long-term monitoring for second-degree DWI convictions. This allows the court to extend supervision beyond the standard probation term, with ongoing testing, treatment, and reporting requirements. The purpose is to maintain oversight for offenders whose history suggests a pattern of impaired driving
How Second-Degree DWI Affects Your Life
Beyond the criminal penalties, a second-degree gross misdemeanor DWI conviction creates lasting consequences:

Employment
A gross misdemeanor conviction appears on background checks. While Minnesota's Ban the Box law limits when employers can ask about criminal history, the conviction is still visible in later stages of hiring. Certain professions — nursing, teaching, commercial driving, law enforcement — have specific disqualification standards that a gross misdemeanor DWI can trigger.

Insurance
Your auto insurance rates will increase dramatically — typically 88% to 300%, depending on your carrier. While Minnesota does not use or require standard SR-22 insurance forms, you will be required to file a formal Minnesota Insurance Certification form with the DVS to verify you carry the state’s mandatory minimum liability limits. Some insurers will drop you entirely, forcing you to find coverage through the high-risk pool.

Travel
DWI is a serious criminal offense in Canada, no matter how Minnesota classifies it. Canadians with a DWI (even a misdemeanor) conviction can be denied entry at the Canadian border for up to 10 years without a special Temporary Resident Permit or Criminal Rehabilitation application.

Future DWI charges
A second-degree conviction counts as a prior qualified incident. If you're arrested for DWI again within 10 years, you'll face first-degree felony charges with a mandatory minimum of 3 years. Under the 20-year administrative lookback, this conviction follows you for two decades for license revocation and interlock purposes. Furthermore, getting caught driving any vehicle without your required interlock device or attempting to tamper with the equipment has been elevated from an administrative infraction to a standalone Gross Misdemeanor criminal offense.

Expungement
Gross misdemeanor DWI convictions may be eligible for a court-petitioned expungement after a 3-year waiting period from the date of your final discharge from probation. Note that Minnesota’s automatic Clean Slate screening explicitly excludes DWI offenses, meaning you must still file a formal petition and appear at a court hearing to have the record sealed.
Defense Strategies for Second-Degree DWI

Challenging the Aggravating Factors
The second-degree charge requires two aggravating factors. If the defense can eliminate even one, the charge drops to third-degree — a meaningful reduction in both the mandatory minimum penalties and the long-term consequences.

Challenging the prior incident.
If the prior DWI was obtained without proper counsel, involved an invalid plea, or falls outside the 10-year lookback for criminal purposes, it may not qualify as an aggravating factor. This is technical work that requires pulling records from the prior case and examining whether constitutional rights were protected.

Challenging the BAC
If the 0.16% threshold is one of the aggravating factors, every defense related to the accuracy of the chemical test becomes relevant. DataMaster calibration issues, rising BAC, mouth alcohol contamination, medical conditions (GERD, diabetes), and procedural errors in test administration can all undermine the BAC result. Dropping the BAC below 0.16% eliminates one aggravating factor and potentially reduces the charge.

Challenging the child-in-car factor
The statute requires that the child be under 16 and more than 3 years younger than the driver. Age verification and the specific relationship between the driver and the child's ages can be examined.

Challenging the Stop, Arrest, and Test
All of the
standard DWI defense strategies
apply to second-degree cases:

Negotiating a Charge Reduction
In some cases, the most practical defense strategy is negotiating with the prosecutor to reduce the charge from second-degree to third-degree DWI. While this is still a gross misdemeanor, the mandatory minimum penalties are lower, and the signal to the court is less severe. A skilled defense attorney who understands the local prosecutors and court culture can identify cases where a reduction is realistic.
What to Do If You're Facing Second-Degree DWI Charges

Request your administrative hearing immediately.
You have a strict 60-day deadline from receiving the notice of revocation to file an Implied Consent petition for judicial review to challenge your license loss in court. However, your temporary paper driving permit will only protect your driving privileges for the first 14 days following your arrest. This deadline applies regardless of the degree of the charge.

Get an experienced DWI attorney
Second-degree DWI sits in a critical position — it's the last stop before felony territory. The outcome of this case determines whether your next DWI (if there ever is one) is a gross misdemeanor or a felony with mandatory prison time. The stakes are high enough to justify specialized representation.

Begin your chemical dependency assessment early.
Completing the assessment before the court orders it demonstrates initiative and can influence the court's sentencing decisions.

Comply with all release conditions.
Any violation — a positive test, a missed check-in, driving without authorization — damages your case and your credibility with the judge.

Frequently Asked Questions About Second-Degree DWI in Minnesota
What is second-degree DWI in Minnesota?
Second-degree DWI is a gross misdemeanor charge under Minn. Stat. § 169A.25. It applies when two or more aggravating factors are present at the time of the offense: a prior qualified impaired driving incident within 10 years, a BAC of 0.16% or higher, or a child under 16 in the vehicle.
Is second-degree DWI a felony in Minnesota?
No. Second-degree DWI is classified as a gross misdemeanor — more serious than a standard misdemeanor but below a felony. The maximum penalty is 1 year in jail and a $3,000 fine. However, a subsequent DWI within 10 years can result in first-degree felony charges.
What is the mandatory minimum jail time for second-degree DWI?
If you have one prior qualified incident within 10 years, the mandatory minimum is 30 days of incarceration, with at least 48 hours served consecutively in jail. The remainder can be served through community service or home monitoring. With two or more priors, the mandatory minimum increases to 90 days.
Can a first-time offender be charged with second-degree DWI?
Yes. If two aggravating factors are present — such as a BAC of 0.16% or higher and a child under 16 in the vehicle — a person with no prior DWI history can face second-degree charges.
How long will my license be revoked for a second-degree DWI?
Revocation periods range from 1 year (BAC under 0.16% with one prior) to 2 years (BAC of 0.16% or higher, or test refusal with a prior). Under HF 2130, the ignition interlock requirement is a minimum of 2 years for a second DWI within 20 years.
Can second-degree DWI charges be reduced?
Potentially. If one aggravating factor can be challenged or invalidated, the charge may be reduced to third-degree DWI. Charge reductions can also be negotiated with prosecutors depending on the circumstances of the case and the strength of the evidence.
What is the difference between second-degree and third-degree DWI?
Third-degree DWI is one step below second-degree, with the primary difference being the number of aggravating factors involved — second-degree requires two or more, whereas third-degree requires just one. Both are gross misdemeanors with the same maximum penalty, but second-degree carries higher mandatory minimums and signals a more serious offense to the court.
Will a second-degree DWI affect my ability to travel to Canada?
Yes. Canada classifies DWI as a serious criminal offense regardless of how Minnesota classifies it. A gross misdemeanor DWI conviction can result in denial of entry for up to 10 years without a special permit or rehabilitation application.
