Fourth-Degree DWI in Minnesota
If you are facing Fourth-Degree DWI in Minnesota, the wording on the complaint does not tell the whole story. A careful review starts with the precise statutory provision, then connects each required element to the witnesses, records, testing, or other evidence the state intends to use. This guide explains that process and the consequences that may follow.

If you hire me, we will work from the source material: the charging document, the applicable law, and the evidence behind each allegation. I will explain where the prosecution has support, where questions remain, and what the possible penalties mean for your life. The goal is a clear plan built around your facts, priorities, and deadlines.
How the statute applies
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.

Why the maximum is not the likely sentence
Sentencing context for Fourth-Degree DWI in Minnesota: This is a misdemeanor, not a felony. The penalty ceiling stated above is the maximum authorized for this charge, not a prediction of the sentence. Minnesota’s felony Sentencing Guidelines grid does not supply the presumptive disposition for this misdemeanor. The charged subdivision, proven facts, any applicable mandatory provision, and lawful sentencing alternatives must be considered separately.
Official sources for this summary
Important: This summary of Fourth-Degree DWI in Minnesota cannot calculate a sentence or replace a review of the complaint. Before advising you, I verify the exact subsection, effective date, definitions, enhancements, criminal history, guidelines or class rules, and controlling decisions.
Analyze the specific charge
Test result or refusal
Trace the source, timing, handling, and limits of the test result or refusal evidence.
Begin with the present § 169A.20 theory
Fourth-degree DWI is the misdemeanor degree for a present violation that is not first, second, or third degree. The State still must prove the charged impairment, concentration, controlled-substance, hazardous-substance, or other qualifying theory. The absence of a higher degree does not substitute for proof of the present offense.
Verify why no higher classification applies
I compare the complaint with §§ 169A.24 through 169A.27 and review any claimed prior incident, high test, child passenger, or refusal theory. That classification check protects against both directions of error: treating a fourth-degree count as consequence-free and importing an aggravating fact the admissible record does not establish.
Keep the misdemeanor and license cases on separate tracks
The 90-day/$1,000 misdemeanor ceiling is not a forecast. A license revocation, ignition-interlock question, assessment or treatment condition, release restriction, insurance issue, and use of the incident in a later enhancement require their own legal sources and timelines.
Fourth-degree DWI still requires proof of a present § 169A.20 violation
For a fourth-degree count, I check the stop and driving evidence, the specific impairment or testing proof, and whether the complaint actually alleges another DWI degree or separate offense. The degree is not raised by a vague reference to “prior history”; qualifying aggravators and separate charges have their own provisions. Meanwhile, an implied-consent revocation under §§ 169A.52–.53 follows a distinct administrative proceeding.
Fourth-degree DWI is a misdemeanor under § 169A.27(2); the ordinary ceiling in § 609.03 is 90 days and a $1,000 fine, not an automatic jail term. The felony Sentencing Guidelines grid does not supply a presumptive sentence for this count. I would examine the actual criminal allegations, any separately cited mandatory provision, and the available sentencing alternatives rather than extrapolate from a higher DWI degree.
The license issue cannot wait for the criminal case to end. A test-failure or refusal revocation under § 169A.52 may be reviewed under § 169A.53, whose judicial-petition period is measured from receipt of the revocation notice. I check that notice, the service date, and any plate or vehicle paperwork separately. Insurance and driving-dependent work are practical concerns, but their actual effect depends on the record and insurer or employer rules.
How the present offense and higher-degree exclusions are checked
The present violation—not an absence to prove
Fourth-degree DWI under § 169A.27 rests on a violation of § 169A.20, subdivision 1. The prosecutor must establish the charged present conduct: driving, operating, or being in physical control of a motor vehicle and the particular impairment or alcohol-concentration theory alleged. The statute does not ask the prosecutor to prove that no aggravating factor exists. Aggravating factors are relevant when deciding whether a higher degree may be charged under §§ 169A.25 or 169A.26. I therefore compare the complaint with the squad video, officer observations, test record, timing, and any evidence bearing on actual driving or physical control; I do not invent an extra defense element.
Impairment and test evidence
The charged clause determines what the test can establish. Section 169A.20, subdivision 1 includes impairment theories and specified concentration or substance-presence alternatives; a concentration charge depends on the statutory threshold and its timing rule, while an impairment charge requires proof of impairment rather than merely a number. I obtain the original breath-instrument or laboratory record, collection and timing documents, relevant medical information, and squad and body-camera video. A refusal allegation belongs to the separate § 169A.20, subdivision 2 offense and can be third-degree DWI under § 169A.26 even without an aggravating factor; it should not be presented as an element of fourth-degree DWI.
The separate driver’s-license track
A fourth-degree criminal count and an administrative driver’s-license action are related but not identical decisions. I preserve the notice and service date, identify whether the license action arose from a test result, alleged refusal, warrant process, or conviction, and compare that record with the criminal complaint. A change to the criminal charge does not automatically resolve a separate license proceeding; the governing notice and statutory alternatives must be reviewed on their own terms.
Current-law and offense-date checkpoint
The current Revisor chapter page identifies one 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 degree elements in §§ 169A.24 through 169A.27. Even so, I check the alleged offense date and the effective-date language before applying the current chapter, particularly when a license or administrative consequence is part of the advice.
The present-offense record drives motions, trial, and negotiation
The most useful review of Fourth-Degree DWI in Minnesota combines dispatch audio, squad and body-camera video, witness information, field-test instructions, breath-instrument or laboratory records, medical information, test advisories or warrants, and every driver’s-license notice. I compare those sources on one chronology, identify what was created contemporaneously and what appeared later, and separate direct observations from repetition or inference. That process can support a suppression issue, expose a missing element, narrow the offense level, strengthen negotiation, or define what a jury would actually need to decide.
I keep the criminal charge, the driver’s-license proceeding, and any vehicle or plate matter on separate timelines so that a deadline in one track is not lost while attention is focused on another. For Fourth-Degree DWI in Minnesota, I prepare for negotiation and litigation at the same time because credible options come from knowing the proof, the law, and the consequences—not from guessing how the case is likely to proceed.
A misdemeanor degree can still create significant separate consequences
No responsible lawyer can calculate an outcome from the title “Fourth-Degree DWI in Minnesota” alone. Before recommending a decision, I want you to understand the strongest evidence on each side, the unresolved investigation, the realistic motion and trial issues, the sentencing framework, and how each available resolution would affect driving privileges, ignition interlock, plate or vehicle consequences, insurance, employment that depends on driving, and any enhancement based on verified history.
Frequently asked questions about Fourth-Degree DWI in Minnesota
How is the charge classified?
Misdemeanor
What is the possible maximum penalty?
Up to 90 days and/or a $1,000 fine.
Does a mandatory sentence apply?
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.
What does the prosecution have to prove?
The state must prove a violation of one of § 169A.20, subdivision 1’s driving, operation, or physical-control theories. Section 169A.27 does not make the absence of aggravating factors an element; test refusal under § 169A.20, subdivision 2 is classified separately.
What records should I preserve before speaking with a lawyer?
Preserve the complaint, citation, hearing notices, release orders, complete messages, original photos or video, witness names, and the reason for the stop, squad and body-camera video, field-sobriety procedures, breath or blood records, test timing, calibration and maintenance information, and driver’s-license notices. Do not contact a complaining witness in violation of an order, and do not post about the case.
A lawyer’s file review of Fourth-Degree DWI in Minnesota
The first pass through a criminal file should be exact, not dramatic. I want the statute and subdivision, the alleged date, the conduct the State says satisfies each element, and the source for every fact that raises the degree or punishment.
Read the count as a set of propositions the State must prove
For Fourth-Degree DWI in Minnesota, the governing text begins with Minn. Stat. § 169A.27. That citation matters because a familiar charge name can contain several statutory routes, definitions, and sentencing rules. I read the exact count, the alleged date, and every incorporated definition before deciding which facts are material and which allegations are simply part of the narrative.
Next, I connect each material fact to evidence the prosecution can actually present. The source might be a witness, a recording, a certified record, laboratory work, device data, or an admissible inference—but it should be identifiable and testable. That approach shows whether the real dispute concerns what happened, how evidence was obtained, whether it is admissible, or whether it proves the required element at all.
The evidence I would ask for first
For Fourth-Degree DWI in Minnesota, 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.
