What Illinois requires
Illinois gives a first-time offender the Monitoring Device Driving Permit, which lets you drive without limits during the statutory summary suspension on one condition: a certified BAIID in the vehicle. The device blocks the engine at 0.025% and carries a camera that photographs whoever is blowing.
- First offense: For the length of the statutory summary suspension; the Secretary of State downloads the device data every 30 to 60 days and asks you to explain any violation it finds
- Lockout threshold: 0.025% — the Secretary of State states the vehicle will not start at that reading or above; Illinois also requires a camera on the device
- Program run by: Illinois Secretary of State, BAIID Division
Why Illinois 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. Grundy County runs at or below the Illinois average — the requirement is set state-wide regardless. 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.

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.
