In-depth legal guide
Minnesota DWI
Minnesota DWI is not one test number or one sentencing tier. Minn. Stat. § 169A.20 reaches driving, operating, or being in physical control of a motor vehicle on several alcohol, drug, cannabis, combination, and refusal theories. Sections 169A.24–.27 then assign the degree; §§ 169A.275–.276 govern separate minimum-sentence questions. A revocation notice can start a civil deadline before the criminal case reaches its first meaningful hearing. I would begin with the actual complaint and notice, not an assumption about what “DWI” means.
You will work directly with me.
If you hire me, I will compare three sets of records: what happened on the road or in the vehicle, what happened during the test request and testing, and what the state claims about priors and aggravating factors. I will also read the revocation notice immediately. Under § 169A.53, subdivision 2, a petition for judicial review of a § 169A.52 revocation generally must be filed within 60 days after receipt of the notice and order; a criminal court date does not replace that petition.
Elements and potential penalties
Section 169A.20, subdivision 1, lists distinct theories. Clauses (1) and (2) address alcohol and controlled-substance influence; clause (3) addresses an intoxicating substance the person knew or had reason to know could impair; clause (4) addresses a combination; clauses (5) and (6) specify .08 and commercial .04 concentration theories; clause (7) addresses specified Schedule I or II substances or metabolites with express cannabis-related exclusions; clause (8) addresses cannabis influence. Subdivision 2 separately criminalizes refusal of a covered breath test or a warrant-required blood or urine test. The proof and available response are not identical across these theories.
- Prohibited conduct
- § 169A.20: driving, operating, or physical control with a specified influence, concentration, substance, cannabis, or qualifying refusal theory.
- Present charge degree
- §§ 169A.24–.27: fourth-degree misdemeanor through first-degree felony; § 169A.03 defines the aggravating and prior-history facts.
- Required sentence
- § 169A.275 counts qualified incidents for nonfelony minimums; § 169A.276 governs first-degree felony sentencing.
- Separate license case
- § 169A.53 generally gives 60 days after receipt of a § 169A.52 notice and order to petition for judicial review.
Compare the degrees and related charged alternatives
Four degrees classify the present charge. Under § 169A.03, subdivision 3, the usual aggravating factors are a qualified prior impaired-driving incident in the preceding ten years, an alcohol concentration of at least .16 at or within two hours of the offense, and a qualifying passenger under 16 who is more than 36 months younger than the driver. One factor elevates a subdivision 1 offense to third degree; two or more elevate it to second degree. A covered refusal is third degree without a factor and second degree with one. First degree instead requires § 169A.24’s specific prior-incident or prior-felony theory.
Felony
- Maximum or consequence
- Up to 7 years and/or a $14,000 fine.
- Minimum or mandatory provision
- Section 169A.276 requires a three-year sentence. Execution may be stayed only under the statute’s conditions; if committed to prison, five years of conditional release follows release from prison.
- Elements and classification facts
- The state must prove a § 169A.20 violation plus the prior-incident or prior-felony facts that make the offense first degree under § 169A.24.
Gross misdemeanor
- Maximum or consequence
- Up to 364 days and/or a $3,000 fine.
- Minimum or mandatory provision
- If the case is a second offense within ten years, § 169A.275 starts with 30 days, with at least 48 hours in local custody, or authorized community-work-service treatment. Higher incident counts carry higher minimums.
- Elements and classification facts
- The state must prove DWI with two or more aggravating factors, or test refusal with one aggravating factor, under § 169A.25.
Gross misdemeanor
- Maximum or consequence
- Up to 364 days and/or a $3,000 fine.
- Minimum or mandatory provision
- If the case is a second offense within ten years, § 169A.275 starts with 30 days, with at least 48 hours in local custody, or authorized community-work-service treatment. Higher incident counts carry higher minimums.
- Elements and classification facts
- The state must prove DWI with one aggravating factor, or qualifying test refusal, under § 169A.26.
Misdemeanor
- Maximum or consequence
- Up to 90 days and/or a $1,000 fine.
- Minimum or mandatory provision
- Section 169A.275 does not impose its repeat-offense custody schedule on a true first incident. A substance-use-disorder assessment, license consequences, fees, and other conditions may still apply.
- Elements and classification facts
- The state must prove a § 169A.20, subdivision 1 violation without an aggravating factor that elevates the degree.
Why degree and incident count must be separate: A high .16 result alone can make a first criminal incident third degree, yet the repeat-offense 30-day minimum in § 169A.275, subdivision 1, is not triggered merely by that number. Conversely, a qualifying prior license loss can count as an incident even without a prior DWI conviction. I would verify both the degree factors and the incident-count record before discussing a plea or minimum sentence.
Degree and offense number answer different questions
A DWI degree describes the classification of the present charge. The mandatory-custody schedule in § 169A.275 instead counts qualified impaired-driving incidents within its lookback period. Those two analyses must be completed separately.
| Degree | Class | Maximum | What generally sets the degree |
|---|---|---|---|
| Fourth degree | Misdemeanor | Up to 90 days and/or $1,000 | A § 169A.20, subdivision 1 violation without an aggravating factor |
| Third degree | Gross misdemeanor | Up to 364 days and/or $3,000 | One aggravating factor, or qualifying test refusal |
| Second degree | Gross misdemeanor | Up to 364 days and/or $3,000 | Two or more aggravating factors, or refusal with one aggravating factor |
| First degree | Felony | Up to 7 years and/or $14,000 | The qualifying prior-incident or prior-felony circumstances in § 169A.24 |
| Incident tier | Starting mandatory term | Important execution details |
|---|---|---|
| First incident | No repeat-offense minimum in § 169A.275 | Assessment, license action, fees, and case-specific conditions may still apply. |
| Second within 10 years | 30 days; at least 48 hours in local custody | The statute permits community work service for days not served and permits specified departures, but retains an unsuspendable floor of 48 hours or 80 hours of community work service. |
| Third within 10 years | 90 days, or the statutory intensive-supervision alternative | At least 30 consecutive days in local custody under the incarceration option; the intensive-supervision option requires at least six consecutive days. Up to 60 days may be home detention under the stated conditions. |
| Fourth within 10 years | 180 days, intensive supervision, or staggered sentencing | The incarceration/staggered alternatives require at least 30 consecutive local-custody days; the intensive-supervision approach requires at least six consecutive days. Up to 150 days of the incarceration minimum may be served on home detention or intensive probation as authorized. |
| Fifth or later within 10 years | One year, intensive supervision, or staggered sentencing | The incarceration/staggered alternatives require at least 60 consecutive local-custody days; the intensive-supervision approach requires at least six consecutive days. The authorized remainder may be served on intensive probation or home detention. |
| First-degree felony | Three-year sentence under § 169A.276 | Imposition or adjudication may not be stayed and the duration may not be shortened. Execution may be stayed only under the statutory conditions. A prison commitment is followed by five years of conditional release. |
Assessment and recommended care: section 169A.275 requires the recommended level of care when the conviction involves an alcohol concentration of 0.16 or more or occurs within ten years of a qualified prior incident, unless the person is committed under the felony provision.
Other consequences: license revocation, plate impoundment, vehicle forfeiture, ignition interlock, long-term monitoring, consecutive sentencing, surcharges, and a possible penalty assessment are governed by separate provisions and depend on the facts and history.
Source: Minn. Stat. § 169A.275 and § 169A.276. This is a framework, not a sentence calculation; the offense date, exact degree, qualified history, disposition, and current statute control.
Why the maximum is not the likely sentence
Sentencing context: The degree-specific ceiling and a mandatory minimum answer different questions. For first-degree DWI, § 169A.276 forbids staying imposition or adjudication and sets a three-year sentence, although execution may be stayed under subdivision 2. For a nonfelony repeat case, § 169A.275 states the applicable custody or alternative framework and its limited departure provisions. If a felony guideline range also matters, its severity level and criminal-history score must be checked against the Guidelines effective for the offense date; a broad felony formula cannot replace the DWI statute.

Do not calculate a sentence from the page title. Read the alleged offense date, the count’s exact subdivision, all prior convictions and qualifying license losses, the .16 evidence, passenger facts, and the proposed disposition. An out-of-state record or prior administrative loss may require closer classification under § 169A.03. A different historical version of the statute may govern an older offense.
Traffic stop
Reconstruct what officers knew before each investigative step.
Field sobriety testing
Trace the source, timing, handling, and limits of the field sobriety testing evidence.
Breath or blood testing
Trace the source, timing, handling, and limits of the breath or blood testing evidence.
Identify the charged § 169A.20 theory before evaluating the degree
A concentration count, an influence count, a specified-substance count, a cannabis-influence count, and a refusal count do not share the same proof. I map the complaint to the precise subdivision, then identify the driving, operation, or physical-control evidence and the source record for every aggravating factor. A result below .08 does not by itself defeat an influence count; a drug detected in a sample does not by itself prove the degree of influence required by the charged clause; and a refusal label does not replace proof of the statutory request and response.
Test the chronology with original records
Dispatch audio, squad and body-camera video, witness observations, test advisories, search-warrant material, breath-instrument files, and laboratory records should be placed on one timeline. That chronology can expose an unsupported assumption about who drove, when physical control ended, whether a test fell within the statutory time, or what was actually said during an alleged refusal. Each source has limits; the analysis should not convert an officer’s summary into proof of a fact the recording or source file does not establish.
Keep degree, sentence, and administrative consequences in separate columns
Sections 169A.24 through .27 classify the present charge. Sections 169A.275 and .276 address different sentencing questions. Sections 169A.52 and .53 govern test-related revocation and judicial review, while §§ 169A.60 and .63 address plate and vehicle consequences. A criminal amendment does not automatically resolve the license file, and a prior conviction or license loss must satisfy the statutory definition and time calculation before it can be counted.
The alleged offense date selects the governing version
The current official Revisor chapter page identifies a 2026 change to chapter 169A: Chapter 97, article 2, section 8 repealed § 169A.54, subdivision 6, an administrative-penalty provision. That repeal does not rewrite the offense theories in § 169A.20 or the degree rules in §§ 169A.24 through .27. It can matter to administrative advice, however, so the alleged offense date, notice date, and session-law effective date must be checked rather than assuming the newest text governs an older incident.
Refusal cases also require theory-specific analysis. In State v. Torrez (Minn. 2025), the Minnesota Supreme Court distinguished the incorporated probable-cause requirement for breath-test refusal from the warrant-based blood-or-urine clause. The decision is not a universal suppression rule; it identifies what the prosecution must prove for the particular refusal theory. I therefore compare the warrant, advisory, requested specimen, probable-cause record, and charged subdivision before applying it.
Degree, prior incidents, and license action are different questions
When you first speak with me, I will ask for the incident and notice dates before giving a view about the charge. Then I can identify whether the prosecution alleges alcohol influence, a concentration threshold, drug or cannabis influence, a specified substance, or refusal. I will separately check the degree, the incident-based minimum, and any live judicial-review filing period. That is more useful than a generic promise to “fight a DWI.”
The most common degree confusion is between the number of prior events and the number printed in the charge name. A person’s first alleged DWI can be third degree if a .16 concentration or qualifying child passenger is established. A second qualifying incident often creates one aggravating factor, but the present count could move higher if another factor is present. The record must also show whether an earlier conviction or license loss meets § 169A.03’s definition and falls within the relevant period.
The existing penalty tables are a map, not a personalized sentence. Section 169A.275 specifies 30-, 90-, 180-day, and one-year starting frameworks as the qualified incident count rises, with different actual-custody, community-work-service, intensive-supervision, and home-detention rules. Section 169A.276 supplies the first-degree felony framework. I would identify the particular subdivision and any permitted departure or stay before quoting an unavoidable number of days.
Driving privileges require a separate document review. Under § 169A.52, the commissioner may revoke for a qualifying test failure or refusal. Under § 169A.53, subdivision 2, the person can petition a district court within 60 days after receiving the notice and order. Plate impoundment under § 169A.60, vehicle forfeiture under § 169A.63, and ignition-interlock eligibility under § 171.306 have their own criteria. None should be described as automatic solely because a DWI complaint was filed.
Trace the proof from stop through notice
Traffic stop
For the stop, I start with the information available at the moment of seizure. Did an officer observe a traffic violation, rely on a dispatch report, or approach a parked car without an initial stop? I compare the report with video and dispatch audio, then separate the basis for initial contact from the facts used to extend the encounter, request tests, or make an arrest. An alleged traffic defect does not itself prove impairment.
Field sobriety testing
Field sobriety exercises are observations, not chemical measurements. I want the instructions actually given, the surface and lighting, footwear, weather, physical or medical limitations, officer training, and uninterrupted video. I compare what the officer counted as a clue with what can be seen, and I do not translate a roadside exercise into a blood-alcohol number.
Breath or blood testing
A breath, blood, or urine result requires the underlying record. For a concentration allegation under § 169A.20, subdivision 1(5) or (6), I check test time against driving or control, the original instrument or laboratory output, maintenance and quality-control material, collection history, and whether the reported result matches the charged threshold. For a clause (7) substance allegation, substance identity and the statute’s exclusions matter. The analysis is different when the charge alleges actual influence rather than a numerical threshold.
License deadlines
The notice and order answer the license question. A § 169A.53 judicial-review petition generally must be filed within 60 days after receipt of a § 169A.52 notice and order, in the county of the alleged offense, with service on the commissioner and stated grounds. Filing does not itself stay the revocation. A request for administrative review under subdivision 1 is a different theory, so I check what was served and when before a deadline expires.
What each record can—and cannot—prove
I use one incident chronology and separate legal columns. The criminal column lists the § 169A.20 theory, elements, admissibility issues, and degree factors. The license column lists § 169A.52 grounds, notice receipt, § 169A.53 petition date, and test or refusal issues. A third column records any § 169A.60 plate order or § 169A.63 forfeiture notice. This prevents a person from treating one court hearing as if it resolved every consequence.
At the charging stage I ask the prosecution to identify each alleged aggravating factor and each prior event it intends to count. At the evidence stage I compare those claims with the certified disposition or administrative record and the statutory definition in § 169A.03. At the negotiation stage I can then explain whether a proposed amendment changes the degree, the incident-based minimum, the license consequence, or only the label. Each of those changes has a different practical value.
A decision requires the full statutory picture
Before recommending a plea, motion, or trial, I want you to see the state’s strongest source evidence, what remains unverified, which degree and minimum actually follow from the provable facts, and what happens to driving privileges independently. A claimed “first offense” is not always fourth degree; a claimed “felony” needs § 169A.24’s qualifying history; and a test result does not settle a refusal allegation. The analysis should leave you able to make a decision, not merely more frightened by the maximum.

Use the linked degree and offense-history guides after confirming what the complaint alleges. The first- through fifth-offense pages explain qualified-incident minimums; the degree pages explain what present facts make the case fourth, third, second, or first degree. They serve different questions. Bring the actual complaint and license notice when you call so that the right guide—not merely the familiar phrase “DWI”—starts the discussion.
Frequently asked questions about Minnesota DWI
These are initial answers under the current official text. A specific case requires the charged subdivision, offense date, proof of each aggravating factor, qualified prior history, the test or refusal record, and every administrative notice.
How is the charge classified?
Fourth degree is a misdemeanor, third and second degree are gross misdemeanors, and first degree is a felony. Sections 169A.24–.27 define the degree-setting circumstances.
Which degree or statutory theory might apply?
Fourth-degree DWI under Minn. Stat. § 169A.27 is a misdemeanor based on a violation of § 169A.20, subdivision 1. Third-degree DWI under § 169A.26 is a gross misdemeanor when that driving violation includes one aggravating factor; a qualifying test-refusal violation under § 169A.20, subdivision 2, is also third degree. Second-degree DWI under § 169A.25 is a gross misdemeanor when the driving violation includes two or more aggravating factors, or the refusal violation includes one. First-degree DWI under § 169A.24 is a felony when its specified prior-incident or prior-felony conditions are met. The complaint must identify the charged theory; § 169A.03 supplies important definitions, including which events qualify as aggravating factors and prior impaired-driving incidents. The number of previous arrests alone does not establish the degree.
What is the possible maximum penalty?
Fourth degree permits up to 90 days and/or $1,000; third or second degree up to 364 days and/or $3,000; first degree up to seven years and/or $14,000. Sections 169A.275–.276 may add minimum sentencing requirements that do not change those ceilings.
Does a mandatory sentence apply?
For a second qualified impaired-driving incident within ten years, § 169A.275, subdivision 1, begins with 30 days, subject to its actual-custody, community-work-service, and departure rules. Third, fourth, and fifth-or-later incidents use the higher subdivision-specific frameworks shown above. First-degree DWI invokes § 169A.276’s three-year sentence; execution may be stayed only under its conditions.
What does the prosecution have to prove?
The state must establish driving, operation, or physical control and the specific § 169A.20 influence, concentration, specified-substance, cannabis, or qualifying-refusal theory charged. It must also establish every § 169A.03 aggravating factor or § 169A.24 prior-history fact needed to prove the alleged degree.
What records should I preserve before speaking with a lawyer?
Keep the complaint, complete revocation notice and order, temporary permit, test or refusal documents, warrant papers, original photos or recordings, possible witnesses, and your own timeline of driving, contact, arrest, and notice receipt. Do not alter digital evidence; request preservation of police video and test source files promptly.
A lawyer’s file review of Minnesota DWI Defense Guide
A useful defense analysis starts by slowing the case down. The title of the charge is not an element, and the largest number in a penalty provision is not a prediction. I read the count, the incorporated definitions, and the alleged facts side by side before I tell a client what I think.
Read the count as a set of propositions the State must prove
The right starting point for Minnesota DWI Defense is Minn. Stat. Chapter 169A, read as it existed when the conduct allegedly occurred. I break the charge into the facts the law truly requires instead of treating the offense name as proof. Any fact that raises the degree or punishment gets its own question: who says it happened, what record supports it, and does the evidence satisfy the definition the statute uses?
I then place those answers on a timeline and test them against the complete record. A police summary may describe a witness, video, message, test, or prior conviction, but the underlying source matters more than the summary. Gaps, inconsistencies, and legal objections should be evaluated separately so that a real weakness is not confused with a technical complaint that has no remedy.
The evidence I would ask for first
For Minnesota DWI Defense Guide, I would not begin with a canned list of defenses. I would begin with the source file: the complete stop and arrest video; dispatch audio; field-sobriety instructions and performance; test advisories, warrants, instrument records, laboratory data, and collection records; the exact service date of every license or implied-consent notice; and certified records for any alleged prior incident. A police summary can identify what an officer or witness says happened, but it cannot substitute for the recording, photograph, data, or document being summarized. The same is true of a complaint. It identifies the prosecution’s theory at the start of the case; it does not prove the theory.
I put those materials on one chronology. That lets me see what was known at each decision point, which account was contemporaneous, what appeared only after people spoke with one another, and where the record is silent. It also keeps an admissibility question separate from a factual one. A fact can be disputed even if the evidence was lawfully obtained. Evidence can also be accurate yet inadmissible for a particular purpose. Those are different arguments and should not be blurred together.
Read the charging document against the offense date
The alleged date matters because statutes, penalty thresholds, definitions, sentencing rules, and published decisions change. I save the version in force on that date and read the session-law history when the current online text is different. I also check whether a later amendment was merely clarifying or made a substantive change; that is a legal question, not an assumption. The same discipline applies to prior convictions and administrative events. A prior must fit the definition the charged statute actually uses, fall within any stated lookback period, and be proved by a reliable record.
I then compare the formal count with the probable-cause narrative and the discovery. If the prosecution’s theory shifts, I want the amended pleading and enough detail to prepare. If several factual alternatives are alleged, I identify whether they are separate elements, alternative means, enhancement facts, or merely evidentiary details. That distinction affects notice, motions, jury instructions, unanimity arguments, and how a verdict form should be read.
Separate an evidentiary weakness from a suppression issue
Not every troubling fact produces a motion to suppress. Suppression ordinarily requires a constitutional, statutory, or rule-based violation with a remedy that reaches the evidence at issue. A weak identification, an incomplete investigation, or a witness inconsistency may be powerful at trial without making evidence inadmissible. By contrast, a stop, search, interrogation, identification procedure, warrant, or test can raise a legal issue even when the resulting evidence appears incriminating. I analyze both tracks and do not promise dismissal simply because one problem exists.
For a search issue, I reconstruct what officers knew before each intrusion and what authority they claimed. For a statement, I examine custody, questioning, warnings, voluntariness, recording, and the complete context. For scientific or technical evidence, I request the method, underlying data, quality-control material, uncertainty information, and chain of custody. For hearsay or confrontation questions, I identify the actual statement, its purpose, the declarant, and the proposed foundation. Specificity matters; “the evidence is bad” is not a motion.
Prepare negotiation and trial at the same time
A plea decision should be compared with the case the State could present at trial, not with the complaint’s maximum penalty in isolation. I want to know the strongest admissible proof, the weakest required element, the realistic motion practice, the likely instructions, and the consequences of every proposed disposition. That includes custody, probation, treatment, restitution, driving, firearm restrictions, registration, employment or licensing, immigration consultation, family-court effects, and record consequences when they are actually triggered. I avoid telling a client that every collateral consequence applies to every conviction.
Trial preparation gives negotiation its credibility. Witness interviews, exhibit review, motions in limine, expert consultation, demonstrative evidence, jury instructions, and a clean theory of the case force both sides to confront what can be proved. Negotiation can continue while that work is underway. The two tracks are not opposites.
A case-law point worth keeping in its proper place
Appellate decisions matter, but a quotation should not be detached from the issue the court was deciding. In State v. Fleck, 777 N.W.2d 233, 236 (Minn. 2010), the Minnesota Supreme Court described sufficiency review as viewing the evidence “in the light most favorable to the conviction.” That is an appellate-review rule, not a reduction of the State’s trial burden. At trial, the prosecution still must prove every element beyond a reasonable doubt. I cite the case for the proposition it actually decided and then return to the charged statute, the jury instructions, and the admissible evidence in the present file.
What I would want you to understand before choosing an outcome
You should be able to identify the exact charge, the facts that set its level, the disputed elements, the evidence that matters most, the motions that have a legal basis, the realistic trial issues, and the concrete effect of each proposed resolution. If an answer depends on a missing report, recording, expert opinion, or certified record, I will say so. An honest answer about what remains unknown is more useful than a confident guess.
