A third-degree DWI in Minnesota is a felony charge that carries jail time, fines, and a mandatory license revocation

In Minnesota, a third-degree DWI is charged when you have two or more prior DWI convictions within the past ten years, or when you refuse a breath or blood test after being arrested. Unlike first and second-degree charges, third-degree is classified as a felony rather than a misdemeanor. This means the penalties are significantly harsher and the conviction creates a permanent criminal record that affects employment, housing, and professional licensing.

The distinction matters because felony convictions carry prison sentences, not just jail time. A third-degree DWI conviction in Minnesota results in a mandatory minimum of 90 days in jail (or up to one year), fines between $3,000 and $10,000, and automatic license revocation for at least three years. You will also be required to complete a chemical dependency assessment and treatment program, install an ignition interlock device in any vehicle you drive, and pay court costs and surcharges that typically add $1,000 to $2,000 to the total financial penalty.

How Minnesota Counts Prior DWI Convictions

Minnesota looks back ten years from the date of your current arrest to count prior DWI convictions. Only convictions count—arrests that were dismissed or acquittals do not. The ten-year window is strict: a conviction from exactly ten years and one day ago does not count toward the total, which can mean the difference between a second-degree and third-degree charge.

The law also includes convictions from other states and tribal courts if they involved impaired driving. A DWI from Wisconsin or Iowa counts the same as one from Minnesota. This matters if you have moved or traveled across state lines. You should review your complete driving record with your attorney to confirm exactly how many countable convictions appear, because the prosecution must prove the prior convictions beyond a reasonable doubt, and records can contain errors.

Refusing a Breath or Blood Test

If you refused a breath or blood test during a DWI arrest, Minnesota treats that refusal as a separate path to third-degree charges. The refusal itself triggers an automatic administrative license revocation through the Minnesota Department of Public Safety, separate from any criminal court case. Your license is typically revoked for one year on a first refusal, and longer on subsequent refusals.

The criminal charge of third-degree DWI based on refusal does not require the prosecution to prove you were actually impaired—only that you refused the test after being lawfully arrested. This makes refusal cases different from cases where a breath or blood test result is the evidence. An attorney can challenge whether the arrest was lawful or whether you were properly informed of the consequences of refusal, but the legal bar is lower than proving impairment.

Jail Time, Fines, and License Revocation

A third-degree DWI conviction carries a mandatory minimum of 90 days in jail. The maximum is one year. The judge has discretion within that range, but cannot sentence you to probation alone or suspend the entire jail sentence. Some judges may allow you to serve part of the sentence through work-release or electronic monitoring, but you will serve time.

Fines range from $3,000 to $10,000, and the court will also impose surcharges and fees. Minnesota adds a $695 DWI surcharge, a $75 crime victim surcharge, and court administration fees. Your driver's license is revoked for a minimum of three years. After revocation, you may be able to request a limited license that allows you to drive to work, school, or treatment, but only after completing a chemical dependency assessment and paying an additional reinstatement fee (typically $680 to $750).

Chemical Dependency Assessment and Treatment

Minnesota requires all DWI offenders to complete a chemical dependency assessment conducted by a licensed evaluator. This assessment determines the level of treatment you need—outpatient counseling, intensive outpatient programs, or inpatient residential treatment. The court will order you to complete whatever level the assessment recommends. You pay for the assessment and treatment out of pocket; costs vary but typically range from $500 to $3,000 depending on the program level.

The assessment must be completed before sentencing or as a condition of sentencing. Treatment can take months, and you must provide proof of completion to the court. Failure to complete the assessment or treatment can result in additional criminal charges or revocation of any conditional release the judge granted.

Ignition Interlock Device Requirements

A third-degree DWI conviction requires installation of an ignition interlock device (IID) in any vehicle you own or regularly drive. The device measures your breath alcohol level before the engine will start. If your blood alcohol content is above a set threshold (typically 0.02%), the vehicle will not start and the device records the failed attempt.

You must pay for installation (usually $100 to $200) and a monthly monitoring fee (typically $60 to $100). The device stays in your vehicle for the duration of your license revocation period, which is at least three years. You are responsible for all maintenance and calibration appointments. Tampering with, removing, or attempting to circumvent the device is a separate criminal offense.

Criminal Record and Long-Term Consequences

A felony DWI conviction creates a permanent criminal record that appears on background checks for employment, housing, professional licensing, and loan applications. Unlike misdemeanor convictions, felony convictions cannot be expunged (sealed) in Minnesota except in very limited circumstances, such as if the conviction is later overturned on appeal.

The felony record affects your ability to work in fields requiring professional licenses—nursing, teaching, law, real estate, and others. Many employers conduct background checks and will not hire applicants with felony convictions. Housing discrimination based on felony records is legal in Minnesota, meaning landlords can refuse to rent to you. You may also lose the right to vote while incarcerated, and some professional organizations impose additional penalties beyond the criminal sentence.

What to Do If You Are Charged

If you have been arrested for a third-degree DWI in Minnesota, request an attorney when ready. You have the right to a public defender if you cannot afford private counsel. Do not discuss the arrest with anyone except your attorney, and do not post details on social media.

Gather any documentation related to your prior DWI convictions and the current arrest—police reports, breath or blood test results, witness information, and any medical conditions that might affect test results. Provide this to your attorney. Your attorney can challenge the lawfulness of the traffic stop, the administration of field sobriety tests, the calibration and operation of breath or blood testing equipment, and the accuracy of prior conviction records used to enhance the charge.

Frequently Asked Questions

Can a third-degree DWI be reduced to a lower charge?

Reduction depends on the specific facts of your case and the strength of the prosecution's evidence. Challenges to the traffic stop, the arrest procedure, or the reliability of test results can sometimes result in dismissal or reduction. Plea negotiations are also possible, though the prosecution has significant leverage because the charge is already a felony. An attorney can evaluate whether reduction is realistic in your situation.

What happens to my vehicle if I am convicted?

Your vehicle is not automatically seized or forfeited in a DWI case. However, you must install an ignition interlock device if you own or regularly drive the vehicle. If the vehicle is registered in someone else's name, that person may face legal liability if you drive it without the device installed.

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

Yes, you may request a limited license after completing a chemical dependency assessment and meeting other requirements. A limited license typically allows driving to work, school, treatment, or medical appointments, but not for personal errands. You must have an ignition interlock device installed in any vehicle you drive on the limited license.

How long does a third-degree DWI case take to resolve?

Timeline varies based on whether you go to trial or accept a plea agreement. Most cases resolve within three to six months if you plead guilty or reach a plea deal. Cases that go to trial can take six months to over a year. Your attorney can provide a more specific timeline based on the court's schedule and the complexity of your case.

Will a third-degree DWI affect my car insurance?

Yes. A felony DWI conviction will cause your insurance rates to increase significantly, and some insurers will cancel your policy. You may be required to obtain high-risk insurance, which costs substantially more. Some insurers will not cover drivers with felony DWI convictions at all, limiting your options.
