If you have been charged with driving while impaired (DWI) in Minnesota, you are facing a legal system that has grown significantly tougher in recent years. Minnesota uses the term DWI rather than DUI, and while both terms refer to impaired driving, understanding the specific penalties under Minnesota law is critical for anyone navigating these charges. The state overhauled its DWI penalty structure in 2025, and the consequences are now among the most serious in the country.
At Sieben Edmunds Miller, our DWI defense attorneys work closely with clients throughout the Twin Cities and greater Minnesota to help them understand their rights, the charges they face, and the most effective path forward. This guide breaks down current Minnesota DWI penalties so you know exactly what is at stake.
How Minnesota Classifies DWI Offenses
Minnesota organizes DWI offenses into four degrees, with first degree being the most serious. The degree of your charge depends on the number of aggravating factors present and your prior DWI history. Aggravating factors under Minnesota law include a blood alcohol concentration (BAC) of 0.16 percent or higher, a prior qualified impaired driving incident within the past 10 years, or the presence of a child under age 16 in the vehicle when the driver is at least three years older than that child.
Here is how the degree structure currently works:
- Fourth-Degree DWI (Misdemeanor): A first-time DWI offense with no aggravating factors. Maximum penalties include up to 90 days in jail and a fine of up to $1,000.
- Third-Degree DWI (Gross Misdemeanor): One aggravating factor is present, or the driver refused chemical testing. Maximum penalties include up to one year in jail and a $3,000 fine.
- Second-Degree DWI (Gross Misdemeanor): Two aggravating factors are present, or a test refusal occurred along with one aggravating factor. Penalties include up to one year in jail and a $3,000 fine, with mandatory minimums applying in many situations.
- First-Degree DWI (Felony): Three or more prior qualifying DWI incidents within the past 10 years, or certain other aggravating circumstances. Penalties can include up to seven years in prison and fines up to $14,000.
The 2025 Law Changes: A New Era for Minnesota DWI Penalties
Effective August 1, 2025, the Minnesota Legislature passed sweeping changes to the state’s DWI framework. These changes were prompted, in part, by a tragic 2024 incident in St. Louis Park in which a driver with five prior DWI convictions struck and killed two people. The legislative response was swift and significant.
The most important change is the extension of the DWI lookback period from 10 years to 20 years for administrative purposes. This means that when determining the length of a driver’s license revocation, Minnesota can now consider DWI convictions going back two decades rather than just one. An offense you thought was safely in the past may now have a direct impact on your current case.
Other major changes effective August 1, 2025 include:
- Mandatory ignition interlock device use for all repeat DWI offenders within 20 years.
- Required completion of a licensed substance use disorder treatment or rehabilitation program before full license reinstatement.
- Extended revocation periods for those convicted of criminal vehicular homicide or criminal vehicular operation involving alcohol.
- A gross misdemeanor charge for driving with a revoked license due to DWI unless the vehicle is equipped with an ignition interlock device.
- The option to pay the $680 license reinstatement fee in installments rather than a lump sum.
Administrative vs. Criminal Penalties
One thing many people do not realize is that a Minnesota DWI triggers two separate processes: criminal prosecution and administrative penalties imposed by the Department of Public Safety. These run independently of each other, which means your license can be revoked even if your criminal charges are later reduced or dismissed.
Administrative penalties begin almost immediately after your arrest. If you fail a chemical test or refuse to take one, your license is subject to immediate revocation. As of the 2025 law changes, if you refuse a chemical test, you now receive 14 days of temporary driving privileges, extended from the previous seven-day window, giving you slightly more time to challenge the revocation or begin the ignition interlock enrollment process.
License Revocation Under Current Law
License revocation timelines have been consolidated under the 2025 legislation to make them clearer and more consistent. First-time offenders face largely the same revocation periods as before the changes, but repeat offenders face dramatically longer consequences:
- Second DWI within 20 years: Mandatory two-year revocation.
- Third DWI in a lifetime: Mandatory six-year cancellation.
- Fourth DWI in a lifetime: Mandatory ten-year cancellation.
These revocation periods are not discretionary. Once imposed, you must complete the ignition interlock program and, in most cases, a substance use disorder treatment program before your full driving privileges are restored.
Criminal Penalties by Degree
Criminal penalties in Minnesota are imposed by the courts following conviction and are separate from the administrative penalties described above. In addition to jail time and fines, conviction can result in mandatory probation, chemical use assessment and treatment, vehicle forfeiture in serious cases, and long-term impacts on employment and housing.
For a first DWI offense with no aggravating factors, you are looking at a misdemeanor charge with relatively limited criminal exposure, though the administrative penalties can still significantly affect your daily life. As the degree of the offense increases, so does the potential for mandatory jail time, including minimum sentences that must be served before alternatives like electronic home monitoring can be considered.
When to Contact a DWI Attorney
Minnesota DWI law is complex, and the 2025 changes have added new layers of consequence that can affect people who may not have realized their older conviction still counted against them. Whether you are facing your first offense or a repeat charge, speaking with an experienced Minnesota DWI defense attorney as soon as possible gives you the best chance of protecting your rights and minimizing the impact on your life.

Frequently Asked Questions About DWI Penalties in Minnesota
What are the penalties for a DUI conviction in Minnesota?
Minnesota calls this offense a DWI rather than a DUI. Penalties depend on the degree of the charge and range from up to 90 days in jail and a $1,000 fine for a misdemeanor fourth-degree DWI, all the way to up to seven years in prison and a $14,000 fine for a felony first-degree DWI. Administrative penalties such as license revocation run separately from criminal penalties.
What is the typical penalty for a first-offense DUI in Minnesota?
A first-time DWI with no aggravating factors is a fourth-degree misdemeanor. You could face up to 90 days in jail and a fine up to $1,000. Administratively, your license will be revoked for 90 days, and you may be eligible for a limited license or ignition interlock after the first 15 days.
What factors can increase or decrease DWI penalties in Minnesota?
Aggravating factors that increase penalties include a BAC of 0.16 percent or higher, a prior DWI within the past 10 years, or having a child under age 16 in the vehicle. The number of aggravating factors determines the degree of the offense. Having no aggravating factors and a clean prior record will generally result in the least severe penalties.
What is the difference between DUI penalties and DWI penalties in Minnesota?
Minnesota does not use the term DUI in its statutes. The official term is DWI, or Driving While Impaired. When people use DUI, they are typically referring to the same offense. The penalties are the same regardless of which term is used. Minnesota’s DWI penalty structure is based on degree of the offense and the presence of aggravating factors.
What happens if someone refuses a breath test during a DWI stop in Minnesota?
Refusing a chemical test is itself a crime in Minnesota and is treated as an aggravating factor. Administratively, your license will be revoked. As of August 1, 2025, you now have 14 days of temporary driving privileges following a test refusal, up from seven days previously. You must act quickly to challenge the revocation or enter the ignition interlock program.
