What Michigan requires
In Michigan the Secretary of State suspends the license on receiving the conviction record, and the interlock is part of the route back to driving. The restricted license and the conditions attached to it are decided through the Secretary of State’s hearing process rather than set as a flat term in the vehicle code.
- First offense: Set through the Secretary of State hearing process as a condition of the restricted license, not fixed as a single term by MCL 257.319
- Lockout threshold: Set by the device standard accepted by the Secretary of State as a condition of the restricted license
- Program run by: Michigan Secretary of State, through its hearing officers
Why Michigan orders these devices
An interlock order is not a judgment about you personally — it is what the state does with every case of this kind, and the reason sits in the crash record.
Source: NHTSA Fatality Analysis Reporting System, 2020–2022. The count covers fatal crashes where police recorded that a driver had been drinking, which is narrower than the federal 0.08 BAC measure and therefore understates the real figure. Isabella County runs above the Michigan average, which is part of why the interlock requirement here is enforced the way it is. What the device changes is measurable too: a car fitted with one cannot be started over the limit, which is why the order attaches to driving privileges rather than to the sentence.

Interlock questions in Mount Pleasant
Where can I get an ignition interlock device installed in Mount Pleasant, MI?
We index 2 certified installation points in Mount Pleasant, run by Smart Start, Intoxalock, RoadGuard Interlock. Addresses are listed above. Book with the provider your paperwork names, not the nearest one — a device approved in one state is not automatically approved in the next, and switching brands mid-term means a second installation fee.
How much does it cost to have an ignition interlock device installed in Michigan?
Michigan does not publish a price, so the honest answer is the national one: NHTSA puts installation at $70 to $90 and monitoring at about $70 a month, roughly $3 to $4 a day. Quotes in Mount Pleasant will sit around that unless the provider is charging for something the state does not require.
Can I drink one beer and still start the car in Michigan?
Almost certainly not. Michigan does not print one fixed number in the statute — the level is set by the certifying agency in the device standard, typically between 0.02% and 0.025% BAC, far below the 0.08% driving limit. The device is not testing whether you are impaired, it is testing whether you drank. One drink shortly before a test is enough on most programs, and the fail is recorded whether or not you try again.
What does an ignition interlock device do?
An ignition interlock is a breath-alcohol tester wired into your car ignition. You blow into it before starting the engine; if your breath alcohol is above the state threshold, the engine will not start.
While you are driving, the device asks for rolling retests at random intervals. Every sample, skipped test, and lockout is recorded and sent to the agency monitoring your case.
