Most people don’t realize how strict Minnesota’s DUI laws have gotten. Seriously. The state just made some of the biggest changes in history, and they hit hard. Whether you call it DUI or DWI (Minnesota officially uses DWI), these laws can affect your license, your job, and your wallet for years.
Let’s break down what you need to know.
What Is DWI in Minnesota?
DWI stands for Driving While Impaired. It means operating a vehicle while you’re impaired by alcohol, drugs, or both.
You don’t even need to be driving down the road. Sitting in your car with the keys nearby while impaired counts. The state calls this “physical control” of a vehicle. It’s broader than most people think.
The legal limit for blood alcohol concentration (BAC) is 0.08%. That’s the standard for regular drivers over 21. But hold on, that’s not the whole story.
Basic DWI Laws
Different BAC Limits for Different Drivers
Minnesota has different rules depending on who you are. Here’s how it breaks down.
Regular drivers over 21: BAC limit is 0.08%. Pretty straightforward.
Drivers under 21: Zero tolerance. Any detectable amount of alcohol can get you charged. Minnesota calls this the “Not a Drop” law. Yep, even 0.01% can land you in trouble.
Commercial drivers: BAC limit is only 0.04%. That’s half the regular limit. And this applies whether you’re driving a commercial vehicle or your personal car. One DWI can end a trucking career.
What Counts as Impaired?
You can get a DWI even if your BAC is under the legal limit. If an officer observes signs that you’re impaired, they can arrest you. This includes drugs, prescription medications, cannabis, or anything else that affects your ability to drive safely.
Cannabis is legal in Minnesota now, but driving high isn’t. There’s no specific legal limit like with alcohol. Officers rely on observed impairment and drug tests.
The Four Degrees of DWI
Minnesota classifies DWI offenses into four degrees. Think of them like levels of seriousness. More aggravating factors equal a higher degree, which means harsher penalties.
Fourth Degree DWI (Misdemeanor)
This is your basic first offense with no aggravating factors.
Penalties include:
- Up to 90 days in jail
- Fines up to $1,000
- License revocation for at least 90 days (or 30 days if you’re convicted)
Wondering if this applies to you? If this is your first DWI and your BAC was under 0.16%, you’re probably looking at a fourth degree charge.
Third Degree DWI (Gross Misdemeanor)
This applies when there’s one aggravating factor. That could be a prior DWI, a BAC of 0.16% or higher, or having a child under 16 in the car.
Penalties include:
- Up to 364 days in jail
- Fines up to $3,000
- Minimum 30 days jail time if this is your second DWI
- License revocation for at least 180 days
Not sure what counts as a violation? Having a kid in the car makes it worse. A lot worse. So does refusing the breath test.
Second Degree DWI (Gross Misdemeanor)
Two or more aggravating factors land you here. Maybe you have multiple prior DWIs, or you had a high BAC with a child present.
Penalties include:
- Up to 364 days in jail
- Fines up to $3,000
- Minimum 90 days jail if this is your third offense
- License revocation for at least one year
- Vehicle forfeiture (the state can take your car)
- Mandatory ignition interlock device
First Degree DWI (Felony)
This is the most serious charge. You’re looking at felony status if you have three or more DWI offenses in the past 20 years, a prior felony DWI, or a prior conviction for criminal vehicular homicide.
Penalties include:
- One to seven years in prison
- Fines up to $14,000
- License revocation for at least six years
- Mandatory minimum sentence of three years (though judges can reduce this in some cases)
Sound complicated? It gets worse with repeat offenses.
Major Changes in 2025: The 20-Year Lookback
Okay, pause. Read this carefully.
Minnesota changed its laws in August 2025, and this is huge. The state used to look back 10 years when counting prior DWI offenses. Now they look back 20 years.
Let me break it down. Say you got a DWI in 2007. Under the old law, that wouldn’t count against you in 2026 because it’s more than 10 years old. But under the new law? It absolutely counts. Your 2007 conviction can still bump up your charges today.
Honestly, this catches a lot of people off guard. Many assume their old DWI doesn’t matter anymore. They find out the hard way. Don’t be one of them.
Aggravating Factors That Make It Worse
The degree of your DWI depends on aggravating factors. Here’s what makes things more serious:
- A prior DWI within the past 20 years (this is the big one now)
- BAC of 0.16% or higher (double the legal limit)
- Having a child under 16 in the vehicle (you must be at least 36 months older than the child)
- Refusing to take a chemical test
- Driving with a revoked or canceled license
Each aggravating factor increases the severity of your charge. Stack them up and you’re facing much harsher consequences.
Refusing the Breath Test
Minnesota has an implied consent law. By driving in the state, you automatically consent to chemical testing if arrested for DWI.
Refuse the test? That’s a separate crime. Test refusal carries its own penalties on top of whatever DWI charges you face.
For a first offense refusal, you’re looking at:
- One year license revocation
- Up to one year in jail
- Fines up to $3,000
You used to get seven days of temporary driving privileges after refusing. Now you get 14 days. That gives you a slightly longer window to challenge the revocation or enter the ignition interlock program, but waiting too long still leads to a full suspension.
License Revocation Periods
Here’s where it gets interesting.
Your license gets revoked based on your BAC level, test refusal, and prior offenses. The revocation periods changed significantly in August 2025.
First offense, BAC under 0.16%: 90 days minimum (or 30 days if convicted)
First offense, BAC 0.16% or higher: One year minimum
First offense, test refusal: One year minimum
Second offense within 20 years: Two years minimum
Three or more offenses: Six to 10 years or more
With prior offenses, these periods can stretch much longer. The 20-year lookback means old convictions can dramatically extend your revocation period.
The Ignition Interlock Program
The ignition interlock device is basically a breathalyzer for your car. You blow into it before starting the engine. If it detects alcohol, your car won’t start. It also requires rolling retests while you’re driving.
Minnesota expanded this program in 2025. Now, if you’re convicted of a second or subsequent DWI, you must participate in the program. Period. There’s no way around it anymore.
Here’s how long you’re stuck with it:
- One prior DWI: Two years
- Two prior DWIs: Six years
- Three or more prior DWIs: 10 years
Previously, the maximum was six years for four or more offenses. They increased it to 10 years. Basically, repeat offenders face much longer program requirements.
Interlock Violations
You’re gonna love this one. Actually, you’re not.
If you violate interlock conditions, your time in the program can restart. Violations include:
- Blowing over 0.02% (yes, even tiny amounts can hurt you)
- Being convicted of another alcohol offense
- Tampering with the device
- Missing service appointments
Even low alcohol readings can cost you time and money. The state takes compliance seriously.
Penalties and Consequences
Let’s talk dollars and jail time.
Fines
- Fourth degree (misdemeanor): Up to $1,000
- Third degree (gross misdemeanor): Up to $3,000
- Second degree (gross misdemeanor): Up to $3,000
- First degree (felony): Up to $14,000
These are maximum fines. Courts can impose less, but don’t count on it.
Jail Time
- Fourth degree: Up to 90 days
- Third degree: Up to 364 days (30-day minimum for second offense)
- Second degree: Up to 364 days (90-day minimum for third offense)
- First degree: One to seven years (three-year mandatory minimum)
Judges can order alternatives like electronic home monitoring or community service for some offenses. But higher degrees carry mandatory minimum sentences you can’t avoid.
License Plate Impoundment
If you have aggravating factors, the state can impound your license plates. This applies to all vehicles registered in your name.
To drive again, you need special plates. People call them “whiskey plates.” They start with the letter W. Everyone knows what they mean.
Removing the impoundment sticker or tampering with these plates is now a crime.
Vehicle Forfeiture
For designated offenses (typically third DWI or higher), the state can seize your vehicle. They actually take your car.
This can happen even on a second or first offense if certain enhancing factors are present. Once they seize it, getting it back is extremely difficult.
Special Circumstances for Commercial Drivers
If you drive for a living, a DWI is devastating. Commercial driver’s license (CDL) holders face much stricter rules.
BAC limit while driving commercial vehicles: 0.04% (not 0.08%)
CDL disqualification for first offense: One year minimum
Second offense: Lifetime CDL ban
That’s right. One DWI and you lose your CDL for a year. Two DWIs and you can never drive commercially again. Ever.
This applies even if you got the DWI in your personal vehicle during off hours. Many trucking companies won’t hire anyone with a DWI on record, regardless of how long ago it happened.
Hold on, this part is important. Federal anti-masking laws prevent prosecutors from negotiating plea deals for CDL holders. Your only option is fighting the charge in court.
If you drive trucks, buses, or any commercial vehicle, a DWI can end your career. Period.
Underage Drinking and Driving
Minnesota enforces zero tolerance for drivers under 21. Any measurable amount of alcohol in your system is illegal.
For a first offense:
- 30-day license suspension
- Up to 90 days in jail
- Fines up to $1,000
If your BAC is 0.08% or higher, you face the same penalties as adult drivers. Being under 21 doesn’t reduce the consequences at that level.
Drivers under 18 go to juvenile court. Drivers 18 to 20 face adult charges.
Driving on ATVs, Snowmobiles, and Boats
Minnesota DWI law covers more than just cars. You can get a DWI on:
- ATVs and off-road vehicles
- Snowmobiles
- Motorcycles
- Boats and watercraft (called BWI, Boating While Intoxicated)
Pretty much anything with a motor. These carry the same penalties as car DWIs, including driver’s license revocations.
Farm equipment used exclusively for agricultural purposes on private property is generally exempt. But that’s about the only exception.
How to Handle a DWI Arrest
Getting arrested for DWI is scary. Here’s what you should know.
You get a seven-day temporary license. After arrest, the officer gives you a temporary driving permit good for seven days. Use this time wisely.
You have 30 days to request a hearing. To challenge your license revocation, you must request a hearing with the Minnesota Department of Public Safety within 30 days of your arrest. Miss this deadline and you lose your chance.
Consider the ignition interlock program. If you qualify, enrolling early can help you keep driving during your revocation period. Full driving privileges require the device, but it’s better than no driving at all.
Get a lawyer. Seriously. DWI cases are complex, and the penalties are severe. An experienced attorney can challenge evidence, negotiate with prosecutors, and potentially reduce charges or penalties.
Right? A lawyer costs money, but losing your license for years costs more.
Criminal Vehicular Homicide and Operation
If you cause injury or death while driving impaired, you face additional charges beyond DWI.
Criminal Vehicular Operation (injury): Up to 10 years in prison and $20,000 in fines
Criminal Vehicular Homicide (death): Similar penalties, with extended license revocation periods
The 2025 law changes extended revocation periods for these offenses. You can’t wait out the revocation either. You must participate in the ignition interlock program to drive again.
Administrative vs. Criminal Penalties
You face two separate processes after a DWI arrest.
Administrative penalties come from the Minnesota Department of Public Safety. They handle license revocations, ignition interlock requirements, and plate impoundments. These happen quickly, often before your criminal case even starts.
Criminal penalties come from the court after conviction. They include jail time, fines, probation, and treatment programs.
Both processes run separately. You can lose your license administratively even if you’re never convicted criminally. That’s why the 30-day hearing request deadline matters so much.
Treatment and Assessment Requirements
Most DWI convictions require chemical dependency assessment and treatment. Minnesota wants repeat offenders to address substance abuse issues.
You’ll need to:
- Complete an assessment at a state-approved facility
- Follow treatment recommendations
- Attend required programs or counseling
- Pay for all assessment and treatment costs
These requirements must be completed before you can get your license back. Treatment programs can last weeks or months depending on your situation.
How to Avoid a DWI
Okay, this one’s obvious, but it’s worth saying.
Don’t drink and drive. Use a rideshare service, designated driver, or taxi. Stay where you are if you can’t get a safe ride.
Know your limits. Even one or two drinks can impair you. People metabolize alcohol differently. When in doubt, don’t drive.
Be aware of medications. Prescription drugs and over-the-counter medications can impair driving. Read warning labels and talk to your doctor.
Understand cannabis laws. Legal possession doesn’t mean legal driving. Cannabis impairment leads to DWI charges just like alcohol.
Recent Changes to Remember
Let me summarize the big changes from 2025.
20-year lookback period: Priors from up to 20 years ago now count against you. This is huge.
Extended ignition interlock requirements: Repeat offenders face much longer program participation. Up to 10 years for three or more offenses.
Stricter compliance rules: Interlock violations restart your program. Even low readings (0.02%) can extend your time.
Expanded eligibility: Criminal vehicular homicide offenders can now participate in the interlock program. They must participate, actually. No waiting out the revocation period.
Tougher enforcement: Tampering with plates or driving without required interlock is now a gross misdemeanor. That means up to one year in jail.
These changes make Minnesota’s DWI laws some of the strictest in the country. They’re designed to reduce repeat offenses and keep impaired drivers off the road.
What Happens to Insurance?
Your insurance rates will skyrocket after a DWI. Most insurance companies consider DWI a major risk factor.
You’ll likely need SR-22 insurance. This is a certificate proving you carry minimum liability coverage. It’s required for license reinstatement in many cases. SR-22 insurance costs significantly more than regular insurance.
Some insurance companies will drop you entirely. Finding affordable coverage after a DWI is difficult and expensive.
Employment Consequences
A DWI conviction creates a criminal record. This can affect employment, especially if driving is part of your job.
Professional licenses may be impacted. Nurses, teachers, lawyers, and others licensed by the state often face disciplinary action after DWI convictions.
Background checks will show the conviction. Many employers ask about criminal history on applications. Honestly, this is one of the most overlooked consequences of a DWI.
Out-of-State DWIs
Minnesota shares DWI records with other states. A DWI from another state counts as a prior offense in Minnesota. The 20-year lookback includes out-of-state convictions.
If you’re from another state and get a DWI in Minnesota, your home state will find out. Most states have reciprocal agreements to share this information.
Can You Get a DWI Expunged?
Minnesota allows some DWI convictions to be expunged (removed from your record), but it’s difficult.
You typically need:
- Only one DWI on your record
- No other criminal convictions
- At least 10 years since conviction
- Completion of all sentence requirements
- Proof that expungement serves public interest
Felony DWIs cannot be expunged. Most repeat offenses don’t qualify either. Expungement is expensive and not guaranteed even if you meet the requirements.
Frequently Asked Questions
What’s the difference between DUI and DWI in Minnesota?
They mean the same thing. Minnesota officially uses DWI (Driving While Impaired), but many people still say DUI. Both refer to operating a vehicle while impaired by alcohol or drugs.
How long does a DWI stay on your record in Minnesota?
Forever, unless you get it expunged. The conviction remains on your criminal record permanently. For license revocation purposes, the 20-year lookback period means it counts against you for two decades.
Can you refuse a breathalyzer test in Minnesota?
You can refuse, but it’s a separate crime with its own penalties. Test refusal leads to automatic license revocation for one year, plus potential jail time and fines up to $3,000.
How much does a DWI cost in Minnesota?
Thousands of dollars. Besides court fines ($1,000 to $14,000), you’ll pay for attorney fees, increased insurance, ignition interlock device installation and maintenance, treatment programs, license reinstatement fees, and lost wages. Total costs easily exceed $10,000 for a first offense.
Can you get a DWI on a bicycle in Minnesota?
No. DWI laws only apply to motor vehicles. Bicycles aren’t motorized, so you can’t get a DWI while riding one. However, you could face other charges like public intoxication or disorderly conduct.
Final Thoughts
Minnesota’s DWI laws got significantly tougher in 2025. The 20-year lookback period and extended ignition interlock requirements mean longer-lasting consequences for repeat offenders.
If you’re arrested for DWI, act fast. Request your administrative hearing within 30 days. Get an experienced attorney. Consider your options for ignition interlock and treatment programs.
The best approach? Don’t drink and drive. Use a rideshare, call a friend, or stay put. The consequences aren’t worth the risk.
Stay informed, stay safe, and when in doubt, find another way home.
