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. DuPage County runs above the Illinois 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.

Questions

Interlock questions in Westmont

Where can I get an ignition interlock device installed in Westmont, IL?

We index 1 certified installation point in Westmont, run by Smart Start. 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 Illinois?

Illinois publishes its own figures rather than leaving it all to vendors: up to $85 to fit the device and up to $110 a month while it stays on the car. Removal is billed separately at the end of the term.

Can I drink one beer and still start the car in Illinois?

Almost certainly not. 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 That is far below any drunk driving limit, which is the point: 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.
