Michigan requires ignition interlock on most occupational licenses. Installation runs $70–$150, monthly monitoring $60–$100, and removal $50–$100—costs your employer won't cover and the court won't waive.
Michigan Occupational License IID Requirement: What the Court Order Actually Mandates
Michigan courts require an ignition interlock device on nearly every occupational license issued after a DUI or OWI conviction, even for first-offense BAC below .17. The device stays installed for the entire duration of your license restriction—typically 90 days to one year—and removal before your court-authorized end date triggers automatic license revocation.
Your court order specifies the approved IID vendors (typically Intoxalock, LifeSafer, Smart Start, or Guardian Interlock in Michigan), the required monitoring frequency, and whether you need a camera-equipped unit. You cannot choose a cheaper out-of-state vendor or a non-camera model if your order requires camera verification. Most Michigan district courts default to camera-equipped devices for all OWI cases as of 2023.
The Michigan Secretary of State does not subsidize IID costs for occupational license holders. Unlike some states that offer indigent hardship waivers, Michigan treats device cost as a non-negotiable condition of restricted driving. If you cannot afford installation, the state position is that you use public transit or employer-provided transportation until your full license is reinstated.
IID Installation Cost in Michigan: Upfront Fees by Provider
Installation fees in Michigan range from $70 to $150 depending on provider, device model, and whether you need same-week emergency installation to meet a court deadline. Standard installation at a provider service center runs $70–$95. Mobile installation at your home or workplace adds $25–$50. Camera-equipped devices required by most Michigan courts add $15–$30 to base installation cost.
Intoxalock and LifeSafer control approximately 70% of Michigan's IID market and typically charge $75–$95 for standard installation. Smart Start and Guardian Interlock run slightly higher at $90–$125, but offer more service locations in rural counties. Installation includes device calibration, vehicle system integration, and initial user training. The appointment takes 60–90 minutes.
Your installation date must fall before your occupational license effective date. Michigan courts will not backdate your restricted driving privilege if you miss installation. Most providers offer next-business-day installation in metro Detroit, Grand Rapids, and Lansing. Outstate counties may require 3–5 business days for scheduling.

Monthly Monitoring Fees: The Cost That Destroys Your Budget
Monthly IID monitoring runs $60–$100 per month in Michigan, billed in advance, and continues for the full duration of your occupational license. A six-month occupational license costs $360–$600 in monitoring fees alone. A 12-month restriction costs $720–$1,200. These fees are non-negotiable and due regardless of how little you drive.
Monitoring includes monthly calibration (required every 30–60 days under Michigan law), data download and transmission to the court and Secretary of State, and 24/7 lockout support if the device malfunctions. Missed calibration appointments trigger a device lockout and a violation report to the court. Most Michigan providers charge a $50–$75 late calibration fee and require an in-person service visit to unlock the device.
Camera-equipped devices add $10–$15 per month to base monitoring cost. Most Michigan district courts now require photo verification on every startup test, which adds this surcharge automatically. You cannot downgrade to a non-camera unit mid-term even if your employer complains about the cost.
IID Removal Cost and What Happens If You Remove It Early
Device removal costs $50–$100 in Michigan and requires a court-authorized removal order or completion certificate from your occupational license term. You cannot remove the device on your own timeline. Early removal—even one day before your authorized end date—constitutes tampering under MCL 257.625k and triggers immediate occupational license revocation, extension of your underlying suspension, and potential criminal charges.
Most providers require 48–72 hours' notice for removal appointments and will not remove the device without documented proof that your restriction has ended. If your occupational license expires but your underlying suspension continues, the device stays installed until your full license is reinstated or a new court order authorizes removal. This catches drivers who assume device removal and license reinstatement happen simultaneously—they do not.
Removal includes final data download, vehicle system restoration, and submission of a compliance affidavit to the Michigan Secretary of State. If your final monitoring period shows any violations (failed tests, missed calibrations, or circumvention attempts), the provider reports them to the court even during the removal appointment. Some courts extend suspensions based on final-week violations discovered during removal.
Total IID Cost Over a Typical Michigan Occupational License Period
A six-month Michigan occupational license with IID costs $570–$850 total: $70–$150 installation, $360–$600 monitoring, $50–$100 removal, plus $90 Secretary of State occupational license fee. A 12-month term costs $960–$1,450. These figures assume zero violations, no missed calibrations, and no device malfunctions requiring service calls.
Violations add cost rapidly. Each failed startup test triggers a $30–$50 incident review fee. Missed calibration appointments cost $50–$75 plus a service call. Camera verification failures (passenger blow attempts, obscured face photos) generate $25–$40 manual review fees. Drivers who attempt to disconnect the device or bypass the system face $200–$500 tampering investigation fees, device replacement costs, and criminal charges.
Employers rarely reimburse IID costs even when the occupational license exists solely to preserve employment. Michigan law does not require employer contribution to device costs, and most companies treat restricted licenses as the driver's personal legal obligation. Budget for the full cost out of pocket.
How IID Costs Interact With SR-22 Insurance Premiums
Michigan requires SR-22 filing on all occupational licenses following OWI, DUI, or suspended-license convictions. Your IID monitoring cost and SR-22 premium stack—you pay both simultaneously. Most high-risk carriers in Michigan (Dairyland, Bristol West, GAINSCO, The General) charge $800–$1,800 per year for SR-22 liability coverage on an occupational license, or $65–$150 per month.
Carriers do not discount SR-22 premiums because you hold a restricted license rather than a full license. The violation on your record drives the rate, not your current driving privilege. Some drivers assume occupational license restrictions reduce exposure and therefore cost—they do not. Insurers rate you as a high-risk OWI driver regardless of your approved driving hours.
Combined monthly cost for IID monitoring plus SR-22 insurance runs $125–$250 per month in Michigan. Over a six-month occupational license term, total compliance cost (IID + SR-22 + occupational license fee) reaches $1,400–$2,600. Most drivers underestimate this by 40–60% when they apply for the restricted license.
What Happens If You Cannot Afford the IID Monthly Cost
Michigan offers no state subsidy, payment plan, or hardship waiver for IID costs on occupational licenses. If you cannot pay installation and first-month monitoring upfront, the device is not installed and your occupational license remains invalid. Courts do not extend deadlines or approve alternative compliance methods.
Some IID providers offer in-house payment plans: half down, remainder over 60–90 days. These plans typically add 8–15% financing cost and require autopay from a checking account. Missing a payment triggers device lockout and a court violation report. Public transit, rideshare to work, or employer-provided transportation are the only zero-cost alternatives, and none satisfy the court's IID mandate.
If your job requires driving and you cannot afford the device, you lose the job. Michigan's occupational license program does not accommodate financial hardship—it accommodates employment necessity, but only for drivers who can pay compliance costs in full.
