What Vermont requires
Vermont sets the alcohol set point at 0.02 by rule: blow at or above it and the car will not start. Once you are moving the device asks for random retests, and a failure or a refusal is logged, then the horn sounds and the lights flash until the engine is off or you give a clean sample. The restricted license is applied for through the DMV, which checks your record first.
- First offense: For the balance of the suspension as a conditional reinstatement; the license renews annually until you are eligible for an unrestricted one
- Lockout threshold: 0.02% — Vermont sets the alcohol set point there by rule; a failed or skipped random retest is logged and sets the horn sounding and the lights flashing until you give a clean sample
- Program run by: Vermont DMV, RDL Unit
Why Vermont 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. Caledonia County runs at or below the Vermont 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.

Where can I get an ignition interlock device installed in St Johnsbury, VT?

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 Vermont?
Vermont 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 St Johnsbury 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 Vermont?
Almost certainly not. 0.02% — Vermont sets the alcohol set point there by rule; a failed or skipped random retest is logged and sets the horn sounding and the lights flashing until you give a clean sample 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.
