A second DUI in Kentucky
Verified · next review
Seven days minimum, and the “or” disappears. On a second offense within ten years both the fine and the jail are imposed, not one or the other, and the minimum sentence cannot be suspended or probated. An aggravating circumstance doubles the floor to fourteen days. At least 48 hours of whatever minimum applies must be served consecutively.
Written any number of ways — a 2nd DUI, a DUI 2nd, a 2nd offense DUI, or a second DUI in KY — and the paperwork will use none of them. Kentucky charges it under a section number, and that is what decides the range below.
Grade. Misdemeanor under KRS 189A.010(5)(b)
Confinement. 7 days to 6 months
Fine. $350 to $500

What turns this DUI into something worse
Each line below is a separate provision with its own punishment range. They stack with the arithmetic of prior convictions rather than replacing it.
| The fact | What it makes it | Detail and source |
|---|---|---|
| Any of six aggravating circumstances | The mandatory minimum doubles and cannot be suspended | The six are listed in the statute: more than 30 mph over the limit; driving the wrong way on a limited access highway; a crash causing death or serious physical injury; a reading of 0.15 or more taken within two hours; refusing the test, except on a first offense; and a passenger under twelve. Four days on a first, fourteen on a second, sixty on a third, 240 on a fourth. Kentucky Revised Statutes § 189A.010 · KRS § 189A.010(11) · checked 2026-09-04 |
The device is a separate track
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.
In Kentucky the interlock term runs 4–6 months and is administered by Kentucky Transportation Cabinet, which runs the interlock program directly — which is why a plea that settles the criminal case does not settle the device. What counts as a violation on it, and what an agency adds to the term, is its own arithmetic: violations and lockouts. Getting it off at the end is a procedure of its own too — removal and waivers.

Kentucky DUI questions
Is there a 2nd DUI in Kentucky with no jail time?
On a second offense within ten years both the fine and the jail are imposed, not one or the other, and the minimum sentence cannot be suspended or probated. An aggravating circumstance doubles the floor to fourteen days. At least 48 hours of whatever minimum applies must be served consecutively.
How likely is jail time for a second DUI in KY?
Start from what the statute forces and what it leaves to the judge. The floor here is 7 days to 6 months, and it moves on the facts: any of six aggravating circumstances means the mandatory minimum doubles and cannot be suspended. Everything above that floor is argued, and the same conviction can end up served in custody, on work release or as a condition of probation depending on the county and the judge. What no one can promise you is a sentence below the statutory minimum — that is not a question of persuasion.
What is the punishment range for a 2nd DUI in Kentucky?
Misdemeanor under KRS 189A.010(5)(b): 7 days to 6 months, and a fine of $350 to $500. The range is set by KRS § 189A.010(5)(b), (8), and the figures on this page come from the statute rather than from a summary of it.

Does an interlock come with it 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.
