Illinois requires ignition interlock for most DUI-related occupational licenses, adding $70–$120/month in monitoring fees on top of installation and removal. Here's the full cost breakdown.
What You'll Pay Monthly for IID Monitoring on an Illinois Occupational License
Ignition interlock device monitoring costs $70–$120 per month in Illinois, billed separately from installation and removal. Most approved providers charge $80–$95/month for the monitoring service itself, which includes data downloads, reporting to the Secretary of State's Breath Alcohol Ignition Interlock Device (BAIID) program, and device calibration visits every 30–60 days.
The monthly fee is not negotiable and runs for the entire duration of your occupational license restriction, not just the court-ordered BAIID period. Illinois Secretary of State rules require continuous IID monitoring from the day your occupational license is issued until you receive full driving privileges again. If your occupational license runs 12 months but your court-ordered BAIID requirement is 6 months, you pay monitoring fees for the full 12 months.
Approved providers in Illinois include Intoxalock, LifeSafer, Smart Start, and Monitech. Monthly costs vary slightly by provider, but all must comply with Secretary of State-approved pricing caps. Installation runs $75–$150 as a separate one-time charge. Removal adds another $50–$75 at the end of your restriction period.
Installation and Removal Fees Are Separate from Monthly Monitoring
Installation fees range from $75 to $150 depending on your vehicle type and provider. Most sedans and smaller vehicles fall at the lower end. Trucks, diesel engines, and vehicles with non-standard electrical systems may trigger the higher installation rate. The provider technician installs the IID at a certified service center, typically requiring 1–2 hours.
Removal costs $50–$75 once your restriction period ends and the Secretary of State issues clearance. You cannot remove the device yourself. Illinois BAIID rules require certified technician removal and a final data download sent to the state before your license reinstatement is processed.
Some providers waive installation fees for low-income applicants who submit financial hardship documentation during the BAIID permit application. Not all providers participate in hardship programs. Contact the provider directly before scheduling installation to confirm eligibility.

Total First-Year IID Cost on an Illinois Occupational License
A 12-month occupational license with IID monitoring costs $1,110–$1,665 total for device expenses alone. This breaks down as: $75–$150 installation, $840–$1,440 in monthly monitoring fees over 12 months, and $50–$75 removal. Add SR-22 filing, Secretary of State reinstatement fees, and occupational license court costs, and total first-year compliance expenses run $2,200–$3,800 for most Illinois DUI occupational license holders.
Monitoring fees are billed monthly and must be current to maintain BAIID compliance. Missing a payment triggers a compliance violation reported to the Secretary of State, which can result in immediate occupational license suspension. Most providers do not offer payment plans for monthly monitoring—it's due in full every 30 days.
If your occupational license runs longer than 12 months, multiply the monthly monitoring rate by the total restriction period. An 18-month restriction costs $1,260–$2,160 in monitoring fees alone before installation and removal.
Illinois BAIID Program Requirements Tied to Occupational License Approval
Illinois issues occupational licenses only after BAIID permit approval for most DUI-related suspensions. You apply for the BAIID permit first through the Secretary of State, then petition the circuit court for the occupational license. The court cannot grant occupational driving privileges until the BAIID permit is active and the device is installed.
BAIID permit applications require proof of IID installation, SR-22 insurance filing, and payment of the $30 BAIID permit fee. Installation must occur before your court hearing for the occupational license. Most circuit courts schedule hearings 30–60 days after BAIID permit issuance, which means you're paying monthly monitoring fees before you receive court approval to drive.
The Secretary of State monitors BAIID compliance throughout your restriction period. Any violation—failed breath test, missed calibration appointment, tampering attempt, or late monitoring payment—triggers a compliance notice. Three violations within 12 months typically result in BAIID permit revocation, which automatically voids your occupational license even if the court order has not expired.
Monitoring Includes Calibration Visits Every 30–60 Days
Monthly monitoring fees cover required calibration visits at your provider's service center. Illinois BAIID rules mandate calibration every 30 to 60 days depending on your violation history and provider. First-offense DUI holders typically calibrate every 60 days. Multiple-offense or aggravated DUI holders calibrate every 30 days.
Each calibration visit involves a data download sent to the Secretary of State, device accuracy verification, and a breath test to confirm proper operation. Visits take 15–30 minutes. Missing a scheduled calibration constitutes a BAIID violation and is reported to the state within 48 hours.
Some providers charge additional fees for calibration visits beyond the standard monthly monitoring rate. Confirm with your provider whether calibration visits are included in the base monthly fee or billed separately. Most Illinois-approved providers include calibration in the $70–$120/month monitoring cost, but diesel or commercial vehicle installations may trigger surcharges.
SR-22 Insurance Required Alongside IID for Occupational License
Illinois occupational license holders must maintain SR-22 insurance filing throughout the restriction period. SR-22 is not insurance—it's a certificate your insurer files with the Secretary of State proving you carry at least state minimum liability coverage: $25,000 bodily injury per person, $50,000 per accident, and $20,000 property damage.
SR-22 filing adds $15–$50 to your policy as a one-time filing fee, but the real cost is the premium increase. Drivers with DUI or multiple violations typically see rates increase 70–150% when SR-22 is added. Monthly premiums for SR-22 insurance on an occupational license run $150–$350/month depending on your violation history, age, and coverage selections.
SR-22 must remain active for the entire occupational license period plus any additional filing duration ordered by the court or Secretary of State. Letting SR-22 lapse even one day triggers immediate occupational license suspension and resets your BAIID compliance clock in most cases. Non-standard carriers that write occupational license SR-22 policies in Illinois include Bristol West, Dairyland, The General, and GAINSCO.
Financial Assistance Programs for IID Costs in Illinois
Illinois offers limited financial assistance for BAIID installation and monitoring through county-level indigency programs. If your household income is below 150% of the federal poverty line, you may qualify for reduced or waived installation fees and a 50% reduction in monthly monitoring costs. Not all providers participate.
You must submit a financial affidavit and supporting income documentation during your BAIID permit application. The Secretary of State reviews hardship applications separately from standard BAIID permits. Approval typically adds 2–4 weeks to your application timeline.
Hardship assistance does not waive monthly monitoring entirely—it reduces the rate, typically to $35–$50/month. Installation fees may be deferred or spread across the first three months of monitoring. Removal fees are not covered under most hardship programs. Contact your IID provider and the Secretary of State BAIID unit to confirm current hardship eligibility before installation.
