The 14 day clock starts the night you refuse, and nobody calls to remind you.

The Michigan State Police campaign that started on August 14 runs through Labor Day, which means the arrests from its first weekend are reaching a deadline most people don't know exists. If you refused the chemical test after an arrest that night, the officer handed you a form, and that form started a 14 day clock that has nothing to do with your court date. The Secretary of State won't call to remind you, and when the two weeks run out the suspension takes effect on its own.

What did you actually refuse?

Michigan treats the roadside and the station as two different tests, and only one of them triggers implied consent. The handheld unit an officer offers at the roadside is a preliminary breath test, and for most drivers refusing it is a civil infraction, which is the ground covered in our piece on refusing field sobriety tests. The test that matters here is the chemical test that comes after the arrest, usually a breath sample on the machine at the station or a blood draw at a hospital, because that's the one Michigan says you already agreed to when you took a license in this state.

Why is there a 14 day deadline?

Because MCL 257.625f gives you 14 days from the date of the notice to request a hearing in writing, and gives you nothing at all if you don't. The notice is the report the officer filled out after the refusal, and it's easy to read as paperwork about the criminal case rather than the opening of a separate administrative one. There's no grace period, no late filing, and no reminder, so the request either goes in on time or the sanction arrives without anyone reviewing the file.

What happens if the deadline passes?

The Secretary of State suspends or denies your license for one year on a first refusal and adds six points to your record, and a second refusal within seven years carries two years. None of that waits for the criminal case, and none of it comes off because the OWI charge is later reduced or dismissed, because the sanction is for the refusal itself rather than for drinking. That's how people end up with a workable resolution in district court and no lawful way to drive to it.

What can the hearing actually decide?

The hearing is narrow, and it covers four things: whether the officer had reasonable grounds to believe you committed one of the operating while intoxicated offenses, whether you were placed under arrest, whether you reasonably refused the test, and whether you were properly advised of your chemical test rights. Whether you were over the limit isn't on that list. Hearings turn on the last question more often than people expect, because the advice of rights is a specific script read from a specific form, and whether it was read correctly is a question of record rather than of opinion.

What if the hearing doesn't go your way?

You can petition a circuit court for restricted driving privileges, which is a different proceeding in front of a judge rather than a hearing officer, and it's the normal next step after a refusal is sustained. Restricted driving isn't automatic there either, since the court weighs hardship along with your record, so the same driving history that produced the refusal sits in the room with you. If your situation has already moved past suspension into revocation, you're in license restoration territory, which runs on a much higher standard of proof.

Does refusing keep the evidence out of your case?

Usually not, because the common practice now is for the officer to apply for a search warrant and take blood anyway, often within the same hour. Refusing tends to produce two things at once, a blood result that comes back weeks later and an implied consent suspension that arrives no matter how the criminal case ends, which is worth knowing before the next holiday weekend rather than after it. Our walkthrough of what happens after an OWI arrest covers the criminal track running alongside all of this, and if you're inside the 14 days right now, reach out today rather than at your first court date.

Quick answers

How long do I have to challenge a breath test refusal in Michigan?

Fourteen days from the date of the notice you were handed after the refusal. The request has to be made in writing to the Secretary of State, and there's no grace period, so a request sent on day 15 doesn't preserve anything.

What happens if I never request the implied consent hearing?

The suspension takes effect on its own. A first refusal carries a one year suspension and six points, and a second refusal within seven years carries two years. It happens without a judge and regardless of what the criminal case does.

Can I still drive after an implied consent suspension?

Sometimes, but never automatically. Once a refusal is sustained, the usual route to restricted driving is a petition to the circuit court, which weighs hardship and your driving record. That's a separate proceeding from both the hearing and the criminal case.
