Minnesota DWI Degrees: Charges, Aggravating Factors, and What They Mean

Does Minnesota Call It DWI or DUI?

Minnesota’s statute uses driving while impaired, or DWI. The offense includes driving, operating, or being in physical control of a motor vehicle while impaired under the specified statutory alternatives. An alcohol concentration of at least 0.08 is one route to a charge; evidence of impairment is another. The law separately addresses controlled substances, cannabis, combinations of substances, and commercial vehicles. A number below 0.08 does not automatically resolve every possible DWI allegation. [5]

Start by reading the precise subdivision on the complaint. A laboratory result, an officer’s observations, and a refusal allegation answer different factual questions. Someone charged with multiple counts from one incident should identify the alleged basis for each count rather than assume every count describes a different driving event.

Fourth-Degree DWI: the Misdemeanor Baseline

Section 169A.27 classifies fourth-degree DWI as a misdemeanor. It is commonly the charge for an alleged impaired-driving violation without a qualifying aggravating factor or another basis for a higher degree. The classification does not make the case equivalent to a parking ticket: Minnesota’s misdemeanor definition permits incarceration, while a petty misdemeanor is not a crime. [1] [9]

For example, a person with no qualifying prior incident may still face several legal questions after an arrest: whether the stop was lawful, whether the evidence establishes impairment, and what a separate license notice requires. The degree describes the charging level; it does not supply the answers to those questions.

Third-Degree DWI and Test Refusal

Third-degree DWI is a gross misdemeanor when an impaired-driving violation has one aggravating factor. Test refusal is also classified as third-degree DWI without an additional aggravating factor, subject to the statutes governing higher degrees. Refusal is a separate statutory allegation; it is not simply an admission that a person was over the alcohol limit. [2] [5]

That distinction explains why two people without prior DWI convictions can receive different charging levels. One case may allege a single high-concentration aggravator; another may allege refusal of a legally required evidentiary test. Each requires examination of its own elements and supporting record.

Second-Degree DWI: Different Rules for Impairment and Refusal

An impaired-driving violation with two or more aggravating factors is second-degree DWI. A test-refusal violation with one aggravating factor is also second-degree DWI. Both are gross misdemeanors. The degree statute refers to additional mandatory-penalty and monitoring provisions that may apply, so the degree alone is not a complete sentencing calculation. [3]

A useful review separates the current driving allegation from each proposed enhancement. Ask which prior event is being counted, what date applies, and which documents establish its legal status. A shorthand criminal-history entry should be checked against the original disposition and licensing record.

What Counts as an Aggravating Factor?

The statutory factors include a qualified prior impaired-driving incident within the preceding ten years; an alcohol concentration of at least 0.16 at the time of the offense or measured within two hours; and a passenger younger than 16 who is more than 36 months younger than the driver. The passenger’s age and the age difference both matter. [6]

The prior-incident definitions can include qualifying license losses as well as convictions. Section 169A.09 prevents counting a conviction and related license loss from the same course of conduct as two qualifying prior incidents. Do not count a conviction and related revocation as two independent prior events without applying those definitions. Out-of-state records require a closer comparison than recognizing the letters “DUI” on a report. [6] [10]

When Does a DWI Become a Felony?

First-degree DWI includes a current violation within ten years of the first of three or more qualified prior impaired-driving incidents. A previous felony DWI, or certain specified felony criminal-vehicular convictions, can also establish first-degree treatment. The statute authorizes up to seven years of imprisonment and a $14,000 fine; the actual sentencing analysis includes other law and the person’s record. [4]

A felony assessment should include certified prior orders, the dates of the qualifying events, the current charging document, and any record showing that a prior matter was amended or vacated. Counting arrests rather than qualifying legal events can produce a misleading picture.

The Criminal Case and License Case Are Separate

A DWI incident can produce a criminal prosecution and a separate administrative license action. Section 169A.53 provides a judicial-review process for covered license notices, including a 60-day period measured from receipt of the notice. A future criminal hearing does not extend that separate filing period. Warrant-based blood or urine cases have their own licensing statute. [7] [8]

Keep a separate calendar entry for each document. A police-release form, criminal complaint, license-revocation notice, and plate-related notice may arrive at different times. Resolving one part of the incident does not justify assuming that every other restriction has ended.

Build a Record That Answers the Charging Questions

Organize the complaint by count, then list the facts offered for impairment, test refusal, and each aggravating factor. Keep a timeline that distinguishes driving, contact with officers, testing, release, and receipt of notices. Preserve original files rather than editing videos or messages into a selective summary.

• Complaint, citation, and court notices.
• Breath-test record or laboratory report and any test advisory.
• License notices and the date each was received.
• Prior conviction, discharge, and license-revocation records.
• A chronology identifying disputed facts and available witnesses.
