Michigan Ignition Interlock (BAIID) Lawyer

When you win a Michigan license restoration hearing, you usually do not walk out with full privileges. You get a restricted license that requires an ignition interlock device (BAIID) on every vehicle you own or operate. That device, and the rules around it, are where a hard-won restoration can quietly fall apart — so it is worth understanding exactly how the period works. Baldori Law handles interlock issues and violation hearings for clients across Michigan.

The Restricted License and the One-Year Clock

The plain rules: you will have the interlock on every vehicle you own or operate, you pay for it, and it stays for at least one year — the hearing officer decides how long the restricted period actually runs before you can be considered for a full license (MCL 257.322(6), (9); R 257.313(1)(h)).

One detail matters enormously: the one-year clock does not start on your hearing date. It starts only when the device is verified as installed and the restricted license actually issues (R 257.313a(3)). You also have to service the device on schedule — at least every 60 days. Skip that, and you can turn a clean year into a violation.

Living with the Device Day to Day

A BAIID requires a breath sample before the vehicle will start, and then prompts you for rolling retests while you drive. The device logs every sample, every start-up, and every service visit, and that log is what the state reviews — so the record it builds is only as clean as your habits. A start-up reading that shows alcohol has to be followed within a few minutes by a passing sample below 0.025, or it counts against you; missing a prompted rolling retest counts too. Servicing the device on schedule keeps the log current and keeps an ordinary slip from becoming a reported violation.

Who Pays for the Interlock

You do. Michigan law puts every BAIID cost on the driver (MCL 257.322(6)(a)), and those costs run for the full length of the restricted period. Prices vary by provider, so we will not quote a market figure as if it were fixed. The one official price point in the law is a protection, not a rate: for indigent participants — at or below 150% of the federal poverty level — in the specialty court program, the cost is capped at two dollars a day.

Minor Violations: The 3-Month Setback

Some interlock problems are classified as minor violations (R 257.301a(e)) — for example, three start-up test failures after the device has been installed at least two months, or failing to report for monitoring or service within seven days of the schedule. A minor violation is not the end of your restoration, but it is costly: the consequence (R 257.313a(12)) is that both your BAIID period and the wait before your next hearing each get extended by three months. And three minor violations add up to a major one.

Major Violations: The Original Revocation Comes Back

Major violations (R 257.301a(d)) are far more serious because they reinstate the revocation you worked to lift. They include:

• a reported start-up test showing alcohol without a passing sample below 0.025 within the next few minutes, or failing to take a prompted rolling retest;
• being issued a permit under MCL 257.625g — the temporary paper permit that comes with a new drinking-and-driving arrest;
• a conviction under MCL 257.625l — driving in violation of your interlock-restricted license;
• tampering with or circumventing the device, or attempting to;
• accumulating three minor violations;
• removing the device without authorization (unless it is reinstalled within seven days); and
• operating any vehicle that does not have a functioning BAIID.

When a major violation is reported, the department "shall reinstate the original revocation or denial" after at least five days' notice (R 257.313a(11)). That is why the deadline at the top of this page is the single most important fact here: a written hearing request must be received within 14 days after the reinstatement, and at that hearing the burden is on you to explain what happened (R 257.313a(11)(c)).

What the Violation Hearing Is Like

If your original revocation is reinstated after a major violation and you request a hearing in time, that hearing is not a fresh restoration case — it is your chance to explain what the device recorded. The burden is on you (R 257.313a(11)(c)) to show what happened and why it should not cost you the license. A rolling-retest positive can have an innocent explanation — certain foods, mouthwash, or a medical condition — but "innocent" still has to be proven, with the log, the timing, and often supporting documentation. This is a place where preparation, and moving fast inside the 14-day window, matters enormously.

The Specialty Court (Sobriety Court) Interlock Path

There is a separate route worth knowing about. Under MCL 257.304, a multiple-OWI offender who is admitted to a specialty court can receive a restricted interlock license without waiting out the full revocation — but not until the license has been suspended or revoked for at least 45 days, and only with the judge's certification and a BAIID on each vehicle, limited to enumerated destinations. People still search for this as "sobriety court," but since Public Act 124 of 2023 the current name is the Specialty Court Interlock Program, which covers drug treatment, DWI/sobriety, hybrid, mental-health, and veterans courts. It generally requires two qualifying alcohol convictions, and after completing the program plus a violation-free interlock year you can request an OHAO hearing to remove the restriction — though the revocation minimum that applies to your case (one year, or five for certain repeat revocations) must run before that request.

A Note for CDL Holders

If you hold a commercial license, understand this clearly: Michigan does not offer a restricted or "hardship" CDL. Under MCL 257.319b, a first qualifying violation (including an OWI in any vehicle, and a refusal) carries a one-year CDL disqualification, and two qualifying violations from separate incidents carry a lifetime disqualification — with possible reissue eligibility only after at least ten years and Secretary of State approval. A restricted license from a restoration hearing can let you drive a personal vehicle with an interlock, but it cannot put you back behind the wheel of a commercial vehicle, and no order may authorize a hazmat commercial trip.

Getting to a Full License

After a violation-free interlock year, you can return to OHAO for a "Change or Removal of Restrictions" hearing — again with a current substance use evaluation, screen, and interlock report — to lift the restriction and remove the device. Do not remove the device before that hearing approves it; pulling it early is itself a major violation. The hearing page explains what that second hearing looks like, and if a violation has already put you back at square one, the appeal page covers the deadline-driven options.

Through all of it, keep your own copies — service receipts, calibration logs, and any correspondence with the provider. If the state ever questions a reading, those records are how you answer. And if you are staring at a violation notice right now, do not wait: reach out before the 14-day window closes.
