A first Minnesota DWI is not always a fourth-degree misdemeanor. The degree depends on the present facts, not simply the absence of an old DWI conviction. A first incident is often fourth degree, but criminal test refusal or one aggravating factor can make it third degree. Two aggravating factors can make it second degree. A prior qualifying criminal-vehicular felony can create first-degree exposure even without an earlier DWI conviction.

The arrest also starts more than one legal matter. The criminal case determines guilt and sentence. The Department of Public Safety can revoke driving privileges before the criminal case ends. A plate order, vehicle issue, release condition, insurance problem, or professional-license duty may proceed on its own schedule. The most urgent deadline is often the 60-day period to petition for judicial review of the license revocation.

This guide explains what happens after a first DWI arrest, how Minnesota determines the degree, current 2026 license periods, test and refusal issues, evidence, common defenses, penalties, and practical steps. The law in effect on the incident date controls. This is general legal information and not advice about an individual case.

The first 24 hours after a DWI arrest

A first arrest is disorienting because important documents arrive before the person understands the system. The best immediate response is practical:

Collect the papers. Save the citation, breath-test record, notice and order of revocation, temporary license, booking papers, release conditions, towing record, plate order, and every envelope.
Check the right to drive. An immediate notice ordinarily creates a short temporary privilege. Do not assume the plastic license card remains valid or that driving is allowed until court.
Calendar the civil deadline. A petition for judicial review ordinarily must be filed within 60 days after receipt of the revocation notice. The first criminal hearing does not extend it.
Follow release conditions. Comply with no-use, testing, monitoring, travel, and driving restrictions. Ask counsel to seek clarification or modification when a condition is impossible.
Identify evidence. Preserve receipts, messages, photographs, phone-location data, vehicle data, witness names, and the locations of any cameras. Do not alter a device or contact a witness in a way that could be viewed as pressure.

Write a private timeline while the events are fresh. Include food, alcohol, cannabis or medication, driving, the stop, officer instructions, field exercises, attorney calls, testing, medical conditions, and when notices were served. Send it to counsel rather than posting it or sharing it broadly.

Common mistakes after a first DWI arrest

Waiting for the criminal court date

The civil license deadline is measured from receipt of the revocation notice, not from arraignment. A person may have weeks before the first hearing yet only days left to file a petition. Calling the courthouse, enrolling in interlock, or asking the Department of Public Safety for administrative review does not preserve judicial review.

Assuming the test number is the whole case

A number does not establish a lawful stop, driver identity, physical control, time of driving, proper warrant, valid collection, or reliable analysis. At the same time, a test issue should not distract from observation or driving evidence supporting a separate impairment theory. The defense needs the entire record.

Treating the roadside device as the final test

The preliminary breath test used near the road is generally a screening device for the arrest decision. The later evidentiary breath test uses a different procedure on an approved instrument. A driver may remember one number while the criminal and license allegations rely on another. Obtain both records and their timestamps.

Driving on the plastic card

An officer may return or fail to seize a physical license card, but the card does not override an electronic revocation. Once a temporary privilege expires, driving can create a new charge, towing, and insurance problems. Confirm the privilege through the notice, Driver and Vehicle Services, and counsel.

Starting random programs without understanding their purpose

Responsible early action can help, but a client should know whether an assessment, course, treatment program, or monitoring service is clinically appropriate, court approved, affordable, and likely to satisfy a future condition. A generic online certificate may cost money without helping the case or addressing actual needs.

Posting an explanation or apology

Prosecutors and witnesses can receive screenshots. A post intended to reassure friends can become an admission about driving, drinking, a child passenger, medication, or refusal. Delete nothing in response to an investigation, but stop creating new public commentary and preserve relevant existing content for counsel.

Assuming a first DWI automatically disappears

Minnesota has no rule that automatically dismisses or expunges every first DWI after probation. Court records, driving records, law-enforcement data, licensing disclosures, and private background databases are governed by different rules. A negotiated result should be evaluated for its real record consequences rather than an informal label.

Vehicle storage deserves attention too. Towing after an arrest is not the same as forfeiture, but daily storage charges can become substantial. A registered owner should confirm the lot, proof-of-ownership requirements, insurance needs, and whether release of the vehicle affects any preservation issue. Photographing the vehicle before repair or release can preserve evidence about operability, damage, seating position, or the location of keys.

Why “first offense” does not determine the degree

Minnesota sets most DWI degrees by aggravating factors. Under Minn. Stat. § 169A.03, subdivision 3 (2026), the factors are:

a qualified prior impaired-driving incident within 10 years;
an alcohol concentration of 0.16 or more measured at the time of the offense or within two hours; and
a child under 16 in the vehicle who is more than 36 months younger than the accused.

A person with no prior DWI can have one or two of the other factors. Criminal test refusal has its own degree rules. And an old conviction for a specifically listed substance-related criminal vehicular felony can support first-degree DWI even if the person has never had an ordinary DWI conviction.

“First offense” also means different things in the criminal and licensing systems. The criminal factor generally uses a 10-year window. Current license law may look back 20 years. A person can be treated as a first criminal offender but not a first licensing offender, or can have a record entry that does not legally qualify for either purpose.

How a first Minnesota DWI can be charged

Present facts	Typical degree	Classification
Ordinary DWI; no aggravating factor; no refusal	Fourth degree	Misdemeanor
Ordinary DWI with one factor, such as 0.16 or child passenger	Third degree	Gross misdemeanor
Criminal test refusal with no factor	Third degree	Gross misdemeanor
Ordinary DWI with two factors, such as 0.16 plus child passenger	Second degree	Gross misdemeanor
Refusal plus one factor	Second degree	Gross misdemeanor
DWI after a qualifying prior felony DWI or listed criminal-vehicular felony	First degree	Felony

The table is a framework, not a substitute for the complaint. The state must prove the current offense and every degree-setting fact. A result close to 0.16, a disputed passenger age, a defective old record, or a legally insufficient refusal can change the classification.

Multiple children supply one child-passenger factor, not one factor per child. In State v. Fichtner, 867 N.W.2d 242, 248–50 (Minn. Ct. App. 2015), the Court of Appeals held that “the presence of either a child or multiple children may constitute only one aggravating factor.”

One arrest usually creates a criminal case and a license case

The criminal case

The prosecutor files the criminal charge. The state must prove every element beyond a reasonable doubt. Criminal remedies include suppression, dismissal, acquittal, reduction, negotiation, or sentencing after conviction. The court controls bail, release conditions, trial, and sentence.

The driver’s-license case

The license case is a civil action against the Commissioner of Public Safety. Revocation can begin upon service of the notice, before charges are filed. The driver ordinarily must petition within 60 days to obtain judicial review. The petition must be filed, served, and state the issues with specificity. Administrative review does not extend the period.

The cases overlap but do not automatically decide each other. A prosecutor can reduce a charge while the unchallenged revocation remains. A judge can rescind a revocation while a criminal count continues under different evidence or a different theory. Evidence and testimony from one proceeding can affect the other, so strategy should be coordinated.

What happens in the criminal case?

The first appearance addresses the charge, rights, counsel, bail or release, and future dates. A gross-misdemeanor first DWI may involve more restrictive release conditions than a misdemeanor charge, particularly when custodial-arrest circumstances apply. A person who qualifies may apply for a public defender; private counsel can appear before or after the first date.

Discovery ordinarily includes reports, video, audio, test records, photographs, witness information, dispatch data, warrants, and criminal-history material. The defense may request additional instrument, laboratory, medical, or electronic evidence. Missing discovery should be identified early enough to preserve it and litigate production.

Pretrial motions can challenge the stop, expansion, arrest, warrant, statements, advisory, attorney access, refusal, chemical testing, and admissibility of evidence. The judge may hold an evidentiary hearing and make findings. A ruling can narrow or end a case, but an unfavorable ruling does not require an immediate guilty plea; trial and negotiated options remain.

If no resolution is reached, the defendant has a right to trial. The state must prove the charged theory and degree. The defense can cross-examine witnesses, present admissible evidence, and require proof rather than prove innocence.

What must the state prove?

Minn. Stat. § 169A.20 (2026) prohibits driving, operating, or being in physical control while:

under the influence of alcohol;
under the influence of a controlled substance, qualifying intoxicating substance, cannabis, or a combination;
having an alcohol concentration of 0.08 or more at the time or within two hours;
operating a commercial motor vehicle with an alcohol concentration of 0.04 or more; or
having specified Schedule I or II substances or metabolites in the body, subject to statutory exclusions and defenses.

The state may charge an impairment count and a concentration count from the same incident. A chemical result is not required for an impairment theory, and a result above 0.08 does not excuse the state from proving driving or physical control and a lawful evidentiary foundation.

Physical control is decided from the overall circumstances. In State v. Fleck, 777 N.W.2d 233, 236–37 (Minn. 2010), the Supreme Court identified factors including proximity to the vehicle and controls, keys, passenger status, ownership, and operability. Sleeping in a parked vehicle can present a physical-control question, but presence alone is not the complete test.

The stop, expansion, and arrest

An officer needs a lawful basis for the initial seizure. A traffic violation, observed conduct, crash investigation, or sufficiently reliable report may supply it. The defense should compare the claimed basis to video, road design, traffic law, dispatch information, and what the officer knew at the time—not facts discovered later.

A lawful traffic stop cannot be expanded indefinitely. In State v. Diede, 795 N.W.2d 836, 843 (Minn. 2011), the Supreme Court required “a particularized and objective basis” for reasonable suspicion. The defense timeline should identify when the ordinary traffic mission ended and which facts supported questioning, field exercises, a preliminary test, and arrest.

Field sobriety exercises are affected by instructions, demonstration, surface, slope, lighting, footwear, weather, traffic, injury, disability, fatigue, anxiety, language, and age. Video may show performance more accurately than a list of selected clues in a report.

Probable cause is based on the total circumstances. Odor does not quantify alcohol concentration. Red eyes, speech, balance, driving, statements, field exercises, and a preliminary breath result may combine to support arrest, but each should be checked for accuracy and alternative explanations.

Breath, blood, and urine testing

Breath

The roadside preliminary breath test is a screening tool and is different from the later evidentiary breath test. The evidentiary procedure includes an advisory and a limited right to consult an attorney that cannot unreasonably delay testing. The instrument record, observation period, mouth-alcohol events, sample agreement, control results, maintenance, operator procedure, and video should be reviewed.

In State v. Bernard, 859 N.W.2d 762, 767–74 (Minn. 2015), the Supreme Court upheld the warrantless breath request in that case as a search incident to lawful arrest. The decision does not make every stop, arrest, advisory, attorney opportunity, or test reliable.

Blood and urine

Blood and urine ordinarily require a search warrant or a recognized exception. The defense should examine the warrant application, material statements and omissions, judicial authorization, scope, execution, collection method, kit, preservatives, seals, labeling, storage, transport, chain of custody, laboratory method, controls, calibration, and uncertainty.

Drug and cannabis cases require interpretation. Detection may outlast impairment, and a metabolite may show prior use without proving the effect at the time of driving. The charged theory, compound, concentration, timing, observations, prescription status, and scientific limits must be considered together.

A first-time refusal is a gross misdemeanor

Criminal refusal is ordinarily third-degree DWI even with no prior or other aggravating factor. The prosecution must prove the lawful request and refusal elements. Breath and warranted blood or urine procedures differ. A person may also face an impairment count based on observations even without a completed test.

A refusal can be alleged from words, silence, conditional agreement, delay, or conduct that prevents an adequate sample. But confusion, medical inability, language or hearing barriers, attorney-access problems, incomplete instructions, or an ambiguous exchange may undermine the allegation. The complete audio, video, instrument messages, and call log are essential.

A first administrative refusal generally carries at least a one-year license revocation under current law. The criminal and civil refusal issues overlap but have different proceedings and burdens.

Criminal penalties for a first DWI

Fourth-degree misdemeanor

Under Minn. Stat. § 609.03, subdivision 3 (2026), a misdemeanor carries up to 90 days in jail and a $1,000 fine. A first fourth-degree case has no repeat-offense mandatory jail minimum. The court may still impose jail, stayed jail, probation, a fine, assessment, education or treatment, testing, community work service, and other lawful conditions.

Third- or second-degree gross misdemeanor

A gross misdemeanor carries up to 364 days in jail and a $3,000 fine under section 609.03, subdivision 2. A first incident can reach this level because of refusal, high alcohol concentration, a child passenger, or a combination. The repeat-offense minimums in Minn. Stat. § 169A.275 (2026) do not apply merely because the charge is gross misdemeanor; they depend on a qualified prior in the specified 10-year period.

If the conviction involves 0.16 or more, the court must order the level of care recommended in the substance-use-disorder assessment. A credible assessment and appropriate early care can be important, but treatment should be clinically justified and selected with awareness of reporting and litigation consequences.

The charge degree does not predict the sentence by itself. Judges consider the offense facts, driving, test, crash or risk, cooperation, broader record, assessment, treatment, release compliance, employment, caregiving, restitution, and lawful sentencing limits. A proposal should distinguish accountability from unnecessarily disruptive conditions.

First-offense license revocation under current law

Minn. Stat. § 171.178 (2026) contains the current administrative periods. For a person with no qualified prior impaired-driving incident in the past 20 years, the general minimums are:

ordinary test failure: at least 90 days;
driver under 21 with a result below twice the legal limit: at least 180 days;
test failure at twice the legal limit or more: at least one year; and
test refusal: at least one year.

The incident date, exact result, test type, age, commercial status, prior record, and governing statutory version can change the calculation. A person with an incident inside the 20-year licensing window may face interlock-based treatment even when that incident is too old to be a 10-year criminal aggravating factor.

Ignition interlock may allow lawful driving during part of a revocation, but eligibility and required participation vary. Enrollment does not waive the right to file a civil petition, and it does not extend the filing deadline. Before driving, the person should confirm that the issued privilege, insurance, plates, and installed vehicle all comply.

The judicial-review petition ordinarily must be filed and served within 60 days after receipt of the notice and order. It must state the grounds with specificity. Filing does not automatically stop the revocation. The firm’s Minnesota DWI license revocation guide explains the procedure and hearing issues.

Plate impoundment and the vehicle

A routine first DWI with a result below 0.16, no qualifying child, and no relevant license status ordinarily does not trigger plate impoundment. Under Minn. Stat. § 169A.60 (2026), first-incident plate triggers include a result at twice the legal limit or more and a qualifying child passenger. A plate petition generally has its own 60-day deadline.

A first incident can therefore produce plate impoundment even without a prior. The order may affect the involved vehicle and other vehicles registered or leased in the violator’s name, subject to owner protections and special-series plate rules.

Vehicle forfeiture is different. Current Minn. Stat. § 169A.63 (2026) focuses on felony and specified repeat cases. A first incident based only on a high concentration or child passenger is not automatically a designated forfeiture offense. Towing and storage after arrest are temporary possession issues, not forfeiture of ownership.

Common defense issues in a first DWI

Unlawful stop: the officer lacked a traffic, investigative, or community-caretaking basis for the seizure.
Unlawful expansion: the traffic stop was prolonged or converted into a DWI investigation without particularized suspicion.
Driving or physical control: the state cannot prove who drove, when driving occurred, or that the accused had practical control of the vehicle.
Probable cause: the arrest was based on insufficient or inaccurately reported circumstances.
Breath-test reliability: observation, mouth alcohol, sample agreement, instrument messages, controls, maintenance, or procedure creates a material issue.
Warrant or laboratory evidence: the blood or urine warrant, collection, chain of custody, method, controls, uncertainty, or interpretation is defective.
Drug interpretation: detection does not establish impairment or the charged presence-based element.
Refusal: the request, advisory, attorney opportunity, test availability, medical ability, or alleged refusal is not proved.
Aggravating factor: the 0.16 result, child-passenger facts, or claimed prior does not meet the statute.
Post-driving consumption or prescription defense: a statutory affirmative defense applies and timely notice is given.

A defense is useful when supported by the record. The work is to obtain original evidence, compare it to the statute, and decide which issue can materially change the case.

Plea, trial, and sentencing

A first DWI can end in dismissal, acquittal, suppression, amendment, a negotiated DWI resolution, or conviction after trial. Minnesota has no universal first-offender dismissal program. Local diversion or charging practices, when available, depend on eligibility and prosecutorial policy and should not be promised.

A negotiation should account for the criminal charge, civil license case, plates, test level, companion charges, employment, insurance, immigration, and professional licenses. A reduced criminal charge may not undo the commissioner’s revocation. A plea that seems lenient can still be harmful if its factual basis creates an avoidable licensing or employment consequence.

Before trial, the defense should decide whether expert assistance is useful, which evidence is admissible, whether a civil hearing produced relevant testimony, and how to explain science or physical control clearly. At sentencing, verified treatment, release compliance, employment, caregiving, transportation, and a lawful plan are more useful than vague assurances.

Work, insurance, CDL, and professional licenses

A first DWI can affect commercial driving, company-vehicle eligibility, auto insurance, health-care or public-safety licensing, security work, education, and jobs requiring travel. A CDL holder can face disqualification even when driving a personal vehicle. A professional may have a reporting duty before final disposition.

Noncitizens should obtain advice from qualified immigration counsel before pleading. Consequences depend on the precise charge, accompanying offenses, admissions, sentence, and status. The misdemeanor or gross-misdemeanor label alone is not an immigration opinion.

Insurance and employment decisions can occur independently of the court. Preserving lawful driving through interlock, documenting compliance, and understanding disclosure questions can reduce avoidable disruption, but a lawyer should not advise concealment or an inaccurate application.

Frequently asked questions about a first Minnesota DWI

1. Is a first DWI always a misdemeanor?

No. It is often fourth-degree misdemeanor DWI, but refusal, a 0.16-or-higher result, or a child passenger can create a gross misdemeanor. A qualifying prior felony can create felony exposure.

2. Will I go to jail for a first DWI?

Jail is legally possible, but no repeat-offense minimum applies merely because it is a first incident. The degree, facts, record, assessment, county, negotiation, and judge affect the result.

3. Can I drive after the arrest?

Only if a valid temporary, limited, or interlock-restricted privilege authorizes it. The physical license card is not proof of validity. Read the notice and confirm status before driving.

4. How long do I have to challenge the license revocation?

Ordinarily 60 days after receiving the notice and order. Waiting for the first criminal hearing or requesting administrative review does not extend the period.

5. Is a result below 0.08 a defense?

It defeats the ordinary 0.08-or-more theory if reliable, but the state may still allege impairment based on other evidence. The complete charge and observations must be reviewed.

6. Is exactly 0.16 an aggravating factor?

Yes, if the state proves a timely, admissible, reliable result. The statutory language is 0.16 “or more.” Results near the threshold should be audited carefully.

7. What if I was sleeping in the car?

Minnesota uses a totality-of-the-circumstances physical-control test. Keys, operability, location, position, ownership, and practical ability to move the vehicle matter. Sleeping does not automatically prove or defeat the charge.

8. Can prescription medication cause DWI?

Yes. Lawful possession does not permit impaired driving. Prescription compliance may defend certain presence-based charges but is not a blanket defense to actual impairment.

9. Is refusing the test better than taking it?

Refusal can create a gross-misdemeanor charge and at least a one-year administrative revocation for a first incident. The legal answer depends on the test requested and circumstances; after the fact, the defense should examine whether a lawful refusal was proved.

10. Will my plates be impounded?

They may be for a first incident involving twice the legal limit or a qualifying child passenger. An ordinary first test failure below 0.16 without a child does not trigger plate impoundment solely from the DWI.

11. Can the state take my car?

A routine first DWI is not a designated vehicle-forfeiture offense under current law. Towing after arrest and statutory forfeiture of ownership are different.

12. Can a first DWI be dismissed or reduced?

Yes, when the evidence and law support that outcome. Relevant issues include the stop, expansion, driving, physical control, arrest, warrant, testing, refusal, and aggravating factors. No result is automatic.

13. Do I need a substance-use assessment?

An assessment commonly affects sentencing and probation. A 0.16-or-higher conviction requires the recommended level of care under the DWI sentencing statute. Choose a credible evaluator and provide accurate information.

14. Will a first DWI affect a CDL?

It can. Commercial-driver disqualification rules may apply even when the incident involved a personal vehicle. The ordinary license, CDL, and employment consequences should be reviewed separately.

15. What should I bring to a lawyer?

Bring the citation, test record, revocation and plate notices with envelopes, temporary license, release order, towing papers, medication list, work or licensing concerns, witness names, and any original electronic evidence.

A first DWI should be treated as several coordinated problems

The criminal degree, license revocation, plates, evidence, and practical consequences must be separated and then managed together. Early review protects the civil deadline, preserves video and records, and prevents a first-offense label from hiding gross-misdemeanor or licensing exposure.

If you have been arrested for a first DWI in Minnesota, contact a DWI defense lawyer promptly with the paperwork. The initial review should identify the exact charge, the 60-day deadline, the evidence to preserve, and the lawful options for driving.
