A second DUI in Tennessee
Verified · next review
45 consecutive days, and the treatment door opens at 17. Forty-five consecutive days is the statutory floor, and it is nearly twenty-three times the floor on a first. There is one route out of part of it: after sentencing, a judge may order a licensed substance abuse program instead of the rest of the term, but only once you have served at least 17 days and completed a clinical assessment.
Written any number of ways — a 2nd DUI, a DUI 2nd, a 2nd offense DUI, or a second DUI in TN — and the paperwork will use none of them. Tennessee charges it under a section number, and that is what decides the range below.
Grade. Misdemeanor under § 55-10-402
Confinement. 45 consecutive days to 11 months and 29 days
Fine. $600 to $3,500

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 |
|---|---|---|
| How old the prior conviction is | Ten years to count it — and never past twenty | Tennessee is widely described as having a lifetime look-back. The statute says otherwise. A prior counts if the previous violation falls within ten years of the present one, and once you are a multiple offender every qualifying violation inside those rolling ten-year gaps is counted — but a violation more than twenty years before the present one is never a prior offense. Prior vehicular assault and vehicular homicide convictions are the exception: they count whenever they happened. Tennessee Code § 55-10-405 · Tenn. Code § 55-10-405(a), (c)(1) · checked 2026-09-04 |
The device is a separate track
Tennessee runs the program through the court: you need an Order for Restricted Driver License signed by a judge before any provider will fit the device, plus SR-22 insurance. The order is also what the provider uses to calculate how long you serve, so the paperwork sets the clock.
In Tennessee the interlock term runs Set by the court and is administered by The sentencing court, with the restricted license issued by TN Department of Safety — 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.

Tennessee DUI questions
Is there a 2nd DUI in Tennessee with no jail time?
Forty-five consecutive days is the statutory floor, and it is nearly twenty-three times the floor on a first. There is one route out of part of it: after sentencing, a judge may order a licensed substance abuse program instead of the rest of the term, but only once you have served at least 17 days and completed a clinical assessment.
How likely is jail time for a second DUI in TN?
Start from what the statute forces and what it leaves to the judge. The floor here is 45 consecutive days to 11 months and 29 days, and it moves on the facts: how old the prior conviction is means ten years to count it — and never past twenty. 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 Tennessee?
Misdemeanor under § 55-10-402: 45 consecutive days to 11 months and 29 days, and a fine of $600 to $3,500. The range is set by Tenn. Code § 55-10-402(a)(2); § 55-10-403(a)(2), and the figures on this page come from the statute rather than from a summary of it.
What makes it worse in Tennessee?
How old the prior conviction is — ten years to count it — and never past twenty.
Does an interlock come with it in Tennessee?
Tennessee runs the program through the court: you need an Order for Restricted Driver License signed by a judge before any provider will fit the device, plus SR-22 insurance. The order is also what the provider uses to calculate how long you serve, so the paperwork sets the clock. The device requirement and the criminal penalty are separate tracks: one is handled by the court, the other by The sentencing court, with the restricted license issued by TN Department of Safety.
