Minnesota's DWI Reform Bill Makes Penalties Stricter and Adds New Offense Categories

Minnesota passed significant changes to its drunk driving laws through legislation that took effect in recent years, creating new offense categories, raising penalties, and changing how the state handles repeat offenders. The reform created a fourth-degree DWI charge for drivers with a blood alcohol content (BAC) between 0.08 and 0.15 percent, which sits below the existing third-degree threshold. This means more drivers now face criminal charges rather than civil citations, and the penalties increase with each offense level.

The bill also extended how long prior DWI convictions count toward your record. Previously, convictions older than ten years did not count as priors; under the reform, the lookback period is longer, meaning an old conviction can still increase your penalties if you are charged again. The changes explore to both alcohol and drug-impaired driving, and they affect sentencing, license suspension, and mandatory treatment requirements.

Key Takeaways

  • Minnesota's reform created a fourth-degree DWI charge for drivers with a BAC between 0.08 and 0.15 percent, making more first-time offenses criminal rather than civil.
  • Prior DWI convictions now count toward your record for a longer period, so an older conviction can still increase penalties if you face a new charge.
  • Penalties increase with each offense level, including mandatory jail time, fines, license suspension, and treatment requirements that vary by degree.
  • The reform applies to both alcohol and drug-impaired driving, and ignition interlock devices are now required in more cases.

How the Four Degrees of DWI Work Under the New Law

Minnesota now has four levels of DWI charges, each with different penalties. Fourth-degree DWI is the least serious and applies when your BAC is between 0.08 and 0.15 percent with no prior offenses. This is still a criminal charge, not a civil citation, and carries up to 90 days in jail and fines up to $1,000, plus a 90-day license suspension.

Third-degree DWI applies when your BAC is 0.15 percent or higher, or when you have one prior DWI conviction within the lookback period. Penalties include up to one year in jail and fines up to $3,000, plus a one-year license suspension. Second-degree DWI applies with two or more prior convictions and carries up to two years in prison and fines up to $6,000. First-degree DWI is the most serious charge and applies when you cause injury or death while impaired, carrying up to seven years in prison.

The lookback period—how far back the state looks at your prior convictions—determines which degree you face. Under the reform, this period is longer than it was before, meaning convictions that might have aged out of your record under the old law now count toward your current charge.

License Suspension and Ignition Interlock Requirements

Your driver's license suspension begins when ready after arrest in Minnesota, even before conviction. The administrative license suspension is separate from any criminal penalty and happens automatically if you refuse a breath test or if your BAC is 0.08 percent or higher. This suspension lasts 90 days for a first offense, one year for a second offense within ten years, and longer for subsequent offenses.

If you are convicted, you face an additional criminal license suspension on top of the administrative one. For fourth-degree DWI, this is 90 days; for third-degree, one year; for second-degree, three years; and for first-degree, up to ten years. You may be able to get a limited license that allows you to drive to work, school, or treatment, but you must request this from the court.

The reform expanded ignition interlock device requirements. These devices measure your breath alcohol before the car will start. You must install one if you are convicted of third-degree DWI or higher, or if you refuse a breath test. The device stays in your vehicle for at least one year, and you pay for installation and monthly monitoring yourself, which typically costs $60 to $100 per month.

Mandatory Treatment and Sentencing Changes

Minnesota's reform requires treatment and assessment for most DWI convictions. After conviction, you must complete a chemical health assessment conducted by a licensed professional. This assessment determines whether you need treatment for alcohol or drug use disorder. If the assessment recommends treatment, you must complete it as part of your sentence, and the court can order inpatient or outpatient programs depending on the assessment results.

For repeat offenders, treatment requirements become more intensive. A second conviction within ten years typically requires more extensive programming than a first offense. The court can order you to attend Alcoholics Anonymous or similar support groups as part of your sentence, and you must provide proof of attendance to the court.

Jail time is now mandatory for most convictions under the reform. Fourth-degree DWI carries a minimum of three days in jail (though this can sometimes be reduced through work-release or other programs). Third-degree DWI carries a minimum of 30 days. Second-degree carries a minimum of 120 days. These are minimums; judges can impose longer sentences depending on the circumstances of your case.

How the Lookback Period Affects Your Charges

The lookback period is the window of time the state uses to count prior DWI convictions. Under Minnesota's reform, this period is longer than before, which means an older conviction is more likely to count toward your current charge. The exact length of the lookback period depends on the specific offense, but generally prior convictions within the last ten to fifteen years count toward determining your current charge level.

This matters because it determines which degree of DWI you face. If you have a conviction outside the lookback period, it does not count as a prior, and you may face a lower charge. If it falls within the period, you face a higher charge with steeper penalties. You should review your criminal history with an attorney to understand how many priors count toward your current situation.

The reform also changed how certain convictions count. Some convictions that previously did not count as DWI priors now do, including certain drug-impaired driving convictions and out-of-state DWI convictions. This means your record may be treated more seriously than it would have been under the old law.

Drug-Impaired Driving and the Reform

The reform applies the same four-degree structure to drug-impaired driving as it does to alcohol-impaired driving. You can be charged with DWI if you are impaired by any controlled substance, including prescription medications, marijuana, methamphetamine, or other drugs. The state does not need to prove a specific blood concentration of a drug the way it does with alcohol; impairment alone is enough.

Drug-impaired DWI charges carry the same penalties as alcohol-based charges at the same degree level. Fourth-degree drug DWI carries the same jail time and fines as fourth-degree alcohol DWI. The main difference is that there is no legal limit for drugs the way there is for alcohol (0.08 percent BAC), so the prosecution must prove you were impaired through other evidence like field sobriety tests, officer observations, or blood tests showing the presence of a drug.

What Happens If You Refuse a Breath or Blood Test

Minnesota has an implied consent law, which means that by driving on Minnesota roads, you consent to a breath or blood test if you are arrested for DWI. If you refuse the test, you face an automatic administrative license suspension of one year for a first refusal, and longer for subsequent refusals. This suspension happens regardless of whether you are convicted of DWI.

Refusing a test also has consequences in court. The prosecution can use your refusal as evidence against you, and the judge or jury may view it as an indication of guilt. Additionally, a refusal can count as a prior offense for purposes of determining what degree of DWI you face on a future charge. Under the reform, refusing a test is treated more seriously than it was before.

You have the right to speak with an attorney before deciding whether to take a test, but the officer is not required to wait long for you to consult one. If you refuse, you should still request a lawyer when ready and understand that your refusal will be documented and used against you.

Frequently Asked Questions

Does a fourth-degree DWI conviction go on my record permanently?

Yes, DWI convictions in Minnesota are permanent criminal convictions and cannot be expunged or removed from your record. This means the conviction will show up on background checks for employment, housing, and other purposes indefinitely. However, you may be able to petition the court for a stay of adjudication in some cases, which delays the conviction, though this is not available for all DWI charges.

Can I get a limited license while my license is suspended?

You may be able to get a limited license that allows you to drive to work, school, medical appointments, or treatment, but you must request this from the court. The court has discretion to grant or deny a limited license, and you must show that you have a genuine need to drive for these specific purposes. You will need to file a petition with the court and may need to attend a hearing.

What if my prior DWI conviction is from another state?

Out-of-state DWI convictions count toward your record in Minnesota under the reform. If you were convicted of DWI or a similar offense in another state, that conviction can be used to increase your charge level in Minnesota. You should tell your attorney about any out-of-state convictions so they understand the full picture of your record.

Do I have to install an ignition interlock device if I am convicted?

You must install an ignition interlock device if you are convicted of third-degree DWI or higher, or if you refused a breath test. For fourth-degree DWI, the device is not mandatory, but the court may order one as part of your sentence. You pay for the device yourself, and it typically costs $60 to $100 per month for monitoring and maintenance.

How long does a DWI conviction affect my driving record?

A DWI conviction stays on your driving record permanently in Minnesota. However, for purposes of determining what degree of DWI you face on a future charge, the state looks back a certain number of years (the lookback period). Even if a conviction is old, it may still count as a prior if it falls within that period, which is why you should understand how far back the state looks in your situation.
