Few moments are more nerve racking than seeing flashing lights in your rearview mirror after you’ve had a drink or two. In Minnesota, the decisions you make in the next 30 minutes can shape your driver’s license, criminal record, insurance rates, and even your job. Minnesota has some of the strictest impaired driving laws in the country, and what you say and do during a DWI stop can either preserve your defense or hand prosecutors their case.
Below are the most damaging mistakes drivers make during a Minnesota DWI traffic stop.
1. Don’t Try to Talk Your Way Out of It
The biggest mistake drivers make is assuming they can charm or explain their way past an officer trained to detect impairment. From the moment the squad car pulls behind you, the officer is documenting everything: how you pull over, how you reach for your license, whether your eyes are bloodshot, and whether your speech is slurred. Volunteering chatty explanations only gives officers more material for their report.
Be polite. Provide your license, registration, and insurance. Beyond that, you are under no obligation to chat about where you’ve been. When asked, we recommend you say, “I’m not discussing my day.”
2. Don’t Admit to Drinking and Don’t Lie About It Either
“Just a couple of beers with dinner” is among the most quoted phrases in Minnesota DWI police reports. Any admission of drinking will be used as probable cause and as evidence against you in court.
At the same time, don’t lie. Telling an officer you haven’t been drinking when your breath says otherwise destroys your credibility. The right move is to invoke your Fifth Amendment right to remain silent: “Officer, I won’t answer questions without my lawyer.”
3. Don’t Volunteer for Field Sobriety Tests
Many drivers don’t realize this: roadside field sobriety tests, the walk-and-turn, one-leg stand, and horizontal gaze nystagmus (the “follow my finger” test), are voluntary in Minnesota. Refusing them is not a crime and does not trigger automatic license revocation.
These tests are designed to be difficult. They’re often performed on uneven shoulders, in poor lighting, in cold weather, while you’re nervous. Even sober people fail them. Politely declining prevents you from generating subjective evidence that an officer will later describe in damning terms on the witness stand.
4. Don’t Confuse the Roadside Breath Test with the Station Test
This is one of the most consequential distinctions in Minnesota DWI law. The Preliminary Breath Test (PBT) is the handheld device used at the roadside. Refusing a PBT is not a crime and carries no license penalties. The evidentiary chemical test (typically the DataMaster DMT at the station, or a blood or urine test) is administered after arrest. Under Minnesota’s laws, refusing it is a separate crime, usually a gross misdemeanor carrying up to one year in jail, a $3,000 fine, and a minimum one-year license revocation. It can also be a felony if you have prior DWI incidents.
Many drivers refuse the wrong test. They think they’re protecting themselves, only to face a refusal charge that may be more serious than the underlying DWI.
5. Don’t Ignore the Implied Consent Advisory
If you’re arrested, the officer must read you Minnesota’s Implied Consent Advisory. It explains that testing is mandatory, that refusal is a crime, and, critically, that you have a limited right to consult with an attorney before deciding. Ask for a phone. Minnesota courts generally find 20 to 30 minutes a reasonable amount of time to reach a lawyer, but you cannot unreasonably delay the test, or you’ll be deemed to have refused.
6. Don’t Consent to a Vehicle Search
Under the Fourth Amendment, an officer generally needs a warrant, probable cause, or your consent to search your vehicle. Drivers often consent because they feel pressured or because they believe refusing would make them look guilty. It does not, and consenting waives a critical constitutional protection.
A simple statement preserves your rights: “Officer, I do not consent to any searches.” The officer may still search if they have probable cause, but your refusal preserves your attorney’s ability to challenge the search later.
7. Don’t Argue, Resist, or Run
Anger, sarcasm, and physical resistance accomplish one thing: more charges. Fleeing or resisting arrest can transform a misdemeanor DWI into a felony situation involving obstruction or fleeing charges. Body cameras and dashcams are recording everything. Stay calm, keep your hands visible, comply with lawful commands, and save your fight for the courtroom.
8. Don’t Post About It on Social Media
After release, the urge to vent online or joke about your night is real. Resist it. Prosecutors routinely review social media for posts, photos, and check-ins that establish a drinking timeline or contradict your statements. Some lawyers believe you shouldn’t delete old posts either, as that could be characterized as destroying evidence.
9. Don’t Skip Court Dates or Ignore Deadlines
A Minnesota DWI arrest triggers two parallel cases: a criminal case and a civil license-revocation proceeding through the Department of Public Safety. To challenge the revocation, you generally must file a petition for judicial review within 60 days. Miss that window, and your license is gone regardless of what happens in criminal court.
10. Don’t Talk to Police After Release Without an Attorney
Investigators sometimes follow up “just to clarify a few things.” Don’t take the bait. Anything you say can be added to the file. Politely tell them you’ll be represented by counsel, then call a lawyer.
Why Working With an Experienced Minnesota DWI Attorney Matters
Minnesota’s DWI laws, covering the .08 standard limit, the .16 enhanced threshold, the .04 commercial-driver limit, and zero tolerance for drivers under 21, and test refusal, are unforgiving. The procedural rules around implied consent and chemical testing are complicated, and small missteps in the first hour of a stop often determine outcomes months later in court.
An experienced, well-trained Minnesota DWI defense attorney knows how to scrutinize the stop for constitutional violations, challenge the calibration and administration of breath and blood tests, examine whether the implied consent advisory was properly given, and protect both your license and your criminal record. Two parallel deadlines, criminal and civil, run from the moment of arrest, and missing either can cost you dearly.
If you’ve been arrested for DWI in Minnesota, exercise your right to remain silent and contact a qualified Minnesota DWI attorney as soon as possible.
