What Kentucky requires
Kentucky pays you in time for good behavior. Take the interlock license and stay violation-free for 90 consecutive days on a first offense, and your six-month suspension shrinks to four. Slip up and the counter restarts — but your suspension never runs longer than it would have without the device.
- First offense: Suspension drops from 6 months to 4 if you clear 90 consecutive violation-free days on the device; second offense 18 months down to 12 (120 clean days), third 36 to 18, fourth 60 to 30
- Lockout threshold: Set by the certified device; a violation restarts the consecutive-day count for the incentive period
- Program run by: Kentucky Transportation Cabinet, which runs the interlock program directly
What the charge itself carries in Kentucky: a first offence, a second and when it becomes a felony — the fine, the jail exposure and how long the licence stays restricted.

Why Kentucky asks for the device
Federal crash records are the backdrop to the rules on this page. Read the share with care though: it depends heavily on how often police obtain an alcohol test, and that varies enormously between states.

Interlock questions in Kentucky
Is an ignition interlock mandatory in Kentucky?
Kentucky pays you in time for good behavior. Take the interlock license and stay violation-free for 90 consecutive days on a first offense, and your six-month suspension shrinks to four. Slip up and the counter restarts — but your suspension never runs longer than it would have without the device. As for how long: suspension drops from 6 months to 4 if you clear 90 consecutive violation-free days on the device; second offense 18 months down to 12 (120 clean days), third 36 to 18, fourth 60 to 30.
How much is an interlock device per month in Kentucky?
Kentucky 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. A quote far above that is the provider's, not the state's.
What are the consequences of an interlock violation in Kentucky?
A recorded event is not automatically a violation, and that distinction decides most cases. Programs differ in what they count and how they count it: some add time per event, others ignore single events and act on a pattern, and several give you a written escape where a retest within five or ten minutes comes back clean. What is uniform is that the decision is made by Kentucky Transportation Cabinet, which runs the interlock program directly from the vendor's report, not at the roadside. The mechanics, state by state and with the statute on each, are on our page about violations and lockouts.
How do I get the interlock restriction off my license in Kentucky?
Not at the workshop, and not on the date in your paperwork. The state releases you first and the device comes out last: you finish the term including anything added to it, sit a final data download at the service center, let Kentucky Transportation Cabinet, which runs the interlock program directly review the record, take what it issues to a licensing office to lift the restriction, and only then book the removal. Most programs also require a clean window before any of that starts — 180 days in Washington, the last 30 in New Jersey, three months in Maryland.
What blood alcohol level will fail an interlock in Kentucky?
Kentucky does not fix the number in the statute itself — it is set by the certifying agency in the device standard, and in practice sits between 0.02% and 0.025% BAC. Either way it is far below the 0.08% driving limit, which is why one drink shortly before a test is enough to fail it: the device is testing whether you drank, not whether you are impaired.
Is there an alternative to an ignition interlock device in Kentucky?
Sometimes, and it is usually stricter rather than easier. The common substitute is continuous alcohol monitoring — a transdermal ankle bracelet that watches the person instead of the car, all day rather than at the ignition. North Carolina writes the trade directly into sentencing: 120 days of monitored abstinence can cut a 30-day minimum to ten, and 90 days can replace a seven-day term. The other alternative is not driving at all, which some states allow you to serve out instead, and which costs you the license for the whole period rather than the device.
Where can I get an ignition interlock device installed in Kentucky?
We index 139 certified installation points across 84 Kentucky cities, run by 6 approved providers, with the densest coverage in Lexington, Louisville, London. Install with a provider the state approves rather than the nearest pin on the map: time on an unapproved device does not count toward the term.
