What Happens If I Refuse a Breathalyzer Test in Minnesota?

September 22, 2026 · LawDiver Research Team

If you only remember one point about refusing a breathalyzer in Minnesota, remember this: A first refusal typically results in a one-year license revocation; longer revocations apply with prior DWI or refusal history, with a right to an administrative and judicial review process. Refusal can be charged as a crime and carries penalties comparable to a test-failure DWI in many cases. Birchfield permits criminal penalties for breath refusal; blood draws for criminal punishment generally require a warrant. Procedure, examples, and the opinions below hang off Minn. Stat. § 169A.51. Minnesota drivers must submit to chemical testing when an officer has probable cause for DWI and reads the implied-consent advisory. The statute covers breath, blood, and urine tests under chapter 169A.

Criminal consequences of refusal

Refusal can be charged as a crime and carries penalties comparable to a test-failure DWI in many cases. Birchfield permits criminal penalties for breath refusal; blood draws for criminal punishment generally require a warrant.

Under Birchfield v. North Dakota, the Fourth Amendment allows criminal penalties for refusing a warrantless breath test incident to a lawful DUI arrest, but generally requires a warrant (or a recognized exception) before the State may impose criminal penalties for refusing a blood draw. Missouri v. McNeely rejected a per-se exigency based solely on natural dissipation of alcohol in the blood. Minnesota statutes and case law implement those federal baselines with local detail.

Walking through Minnesota facts

Use this walkthrough to see which Minnesota authority does the work at each step.

A driver is arrested for DUI in Minnesota and refuses the evidentiary chemical test after the implied-consent advisory.

  1. Identify the administrative consequence under Minn. Stat. § 169A.51: A first refusal typically results in a one-year license revocation; longer revocations apply with prior DWI or refusal history, with a right to an administrative and judicial review process.
  2. Separate that track from the criminal case: Refusal can be charged as a crime and carries penalties comparable to a test-failure DWI in many cases. Birchfield permits criminal penalties for breath refusal; blood draws for criminal punishment generally require a warrant.
  3. Ask whether the refusal can be argued to the jury: Refusal is admissible in the DWI prosecution.
  4. If the request is for blood rather than breath, apply the warrant rule: Breath testing is the usual request; after Birchfield and related Minnesota Supreme Court decisions, criminal blood-test refusal generally requires that the blood draw be authorized by warrant.

In Minnesota the refusal question is answered first by Minn. Stat. § 169A.51, then by the administrative deadline and the criminal case.

Can refusal be used as evidence?

Refusal is admissible in the DWI prosecution.

Prosecutors often argue consciousness of guilt; defense counsel emphasize confusion, inadequate advisories, or medical inability to provide a sample. The precise jury instruction language is state-specific — search Minnesota opinions for “refusal” and “implied consent.”

Breath tests versus blood tests

Breath testing is the usual request; after Birchfield and related Minnesota Supreme Court decisions, criminal blood-test refusal generally requires that the blood draw be authorized by warrant.

Practical tip: a driver who refuses breath may still face a warrant-backed blood draw. Refusal does not create a permanent shield against chemical evidence; it mainly adds administrative (and sometimes criminal) consequences on top of the underlying DUI case.

Practical tips

  • Ask whether the stop and arrest were lawful — implied consent usually requires a lawful DUI arrest first.
  • Diary the administrative hearing deadline immediately.
  • Do not confuse portable roadside breath screens with the evidentiary breathalyzer at the station; statutes often treat them differently.
  • Research Minnesota opinions on implied consent, refusal, and license revocation in LawDiver before a contested DMV hearing.

Key takeaways

  • Primary authority: Minn. Stat. § 169A.51.
  • Administrative hit: A first refusal typically results in a one-year license revocation; longer revocations apply with prior DWI or refusal history, with a right to an administrative and judicial review process.
  • Criminal exposure: Refusal can be charged as a crime and carries penalties comparable to a test-failure DWI in many cases.
  • Evidence: Refusal is admissible in the DWI prosecution.
  • Blood vs. breath: federal Supreme Court doctrine in Birchfield and McNeely still frames warrant rules.

Minnesota drivers must submit to chemical testing when an officer has probable cause for DWI and reads the implied-consent advisory. The statute covers breath, blood, and urine tests under chapter 169A.

Implied consent is not the same as a Miranda warning. Officers typically must advise of the consequences of refusal before requesting a chemical test. Failure to give a required advisory can affect whether the administrative suspension sticks — a frequent issue in Minnesota appellate opinions.

License suspension and administrative hearings

A first refusal typically results in a one-year license revocation; longer revocations apply with prior DWI or refusal history, with a right to an administrative and judicial review process.

The DMV / administrative track often runs separately from the criminal DUI case. Missing the short window to request an administrative hearing can lock in a suspension even if the criminal charge is later reduced or dismissed. Always calendar the administrative deadline the same day as the arrest.
