What Indiana requires
Indiana handles this through specialized driving privileges granted by a court under I.C. 9-30-16, and the interlock is a condition the judge may attach. Two details help: suspensions arising from the same episode are served concurrently, and the court may credit time from a suspension that began before conviction.
- First offense: Set by the court as a condition of specialized driving privileges; the installation period is credited against the suspension
- Lockout threshold: Set by the certified device standard under IC 9-30-8
- Program run by: The petitioning court, with the record held by Indiana BMV
Why Indiana 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. Hendricks County runs at or below the Indiana 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.

Interlock questions in Plainfield
Where can I get an ignition interlock device installed in Plainfield, IN?
We index 2 certified installation points in Plainfield, run by Intoxalock, LifeSafer, 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 Indiana?
Indiana 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 Plainfield 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 Indiana?
Almost certainly not. Indiana 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.
