What Missouri requires

Missouri offers the interlock as a trade: fit the device and you drive immediately on a 90-day restricted privilege, or skip it and sit out a 30-day hard suspension first. The catch is the exit — your installer must certify you finished violation-free before the device comes off, and without that certificate you serve another 30 days.

  • First offense: 90 days on an immediate restricted privilege with the device (request within 15 days of the notice), against a 30-day suspension plus 60-day restricted privilege without it
  • Lockout threshold: Set by the alcohol setpoint in the state device standard (7 CSR 60-2.030); tampering and circumvention are separately defined violations
  • Program run by: Missouri Department of Revenue, Driver License Bureau

Why Missouri 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.

Pike County, 2020–2022

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. Pike County runs above the Missouri 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 Louisiana

Where can I get an ignition interlock device installed in Louisiana, MO?

We index 1 certified installation point in Louisiana, run by Intoxalock. 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 Missouri?

Missouri 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 Louisiana 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 Missouri?

Almost certainly not. Missouri 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.
