What Is the Punishment for DUI in Tennessee?

A first DUI conviction in Tennessee carries a sentence of 11 months and 29 days, suspended, with supervised probation for the remainder. You serve a minimum of 48 hours to 7 days in jail depending on your blood alcohol level. There is a $350 minimum fine plus court costs, an Alcohol Safety Course, a Victim Impact Panel, and you lose your license for a year with an ignition interlock required.

That is the conviction. It is not the only possible outcome, and I will come back to that.

Is Jail Time Mandatory for a First DUI in Tennessee?

For a DUI conviction, yes. Tennessee sets a mandatory minimum, and there is no first offense version that carries zero jail on the DUI itself.

Two things change that.

Some courts accept time at a DUI Center in place of jail. Not all of them, and it is not guaranteed, but I recommend it to every client, and it matters more the higher your Blood Alcohol Concentration (BAC) was.

The other is that a DUI is not the only charge you might end up with. A reduction to Reckless Endangerment or Reckless Driving carries no minimum jail at all.

Your BAC Sets Your Minimum Jail Time

The number on the breath or blood test decides the floor.

  • .08 to .149, a minimum of 48 hours
  • .149 and higher, 7 days
  • Under 21, the threshold is .02
  • Juvenile, any alcohol at all, and it goes to juvenile court

This is why the .15 line matters so much in practice. It is the difference between two days and a week, and it changes what the DA is willing to talk about.

If There Was a Crash and Someone Was Injured

Punishment can increase if there was a crash and someone was injured.

I am deliberately not putting a number on that here, because it depends on facts that are specific to your case and I am not going to guess at yours in public. If someone was hurt, call me and we will talk about what you are actually facing.

Is a DUI a Felony in Tennessee?

Usually not. A first, second and third DUI are misdemeanors in Tennessee. A fourth or higher is a felony.

Misdemeanors are graded Class A, B and C, with A the most serious. A Class A misdemeanor carries up to 11 months and 29 days in jail and a fine of up to $2,500.

Felonies are graded A through E, with A the most severe. They carry a minimum of at least one year in prison, potentially much more, and they are heard in Criminal Court rather than General Sessions. A felony also takes things a misdemeanor does not, including your voting rights and your right to possess a firearm.

How Strict Is Tennessee on DUI?

Strict enough that a first offense has a mandatory jail floor and a full year without your license.

I want to be careful here, because "how strict" invites comparison to other states and that is not a question I am going to answer with a statistic I cannot stand behind. What I can tell you is what the sentence contains, which is above, and that the parts people underestimate are not the jail.

They are the year without a license, the interlock, the insurance, and the professional fallout. Those last longer than the 48 hours.

What Is Worse, a DUI or a DWI?

In Tennessee this is mostly a naming question rather than a severity question, and I have written it up separately: DUI vs DWI in Tennessee.

A DWI in Tennessee is usually a charge someone under 21 receives, and a consequence of this charge is loss of driver's license for 1 year with no eligibility for a restricted license.

What Happens to Your License After a Tennessee DUI

You lose it for a year on a first DUI conviction, and an ignition interlock is required.

At the time of writing this, that is the standard term on a first offense. It is the part of the sentence that outlasts everything else, and it is worth understanding before you decide how to handle the case rather than after.

What Actually Changes the Outcome

Everything above is what a conviction carries. Most cases do not end at the maximum, and a lot of them do not end as a DUI at all.

What actually moves that is unglamorous. The evidence, whether it holds up, and what you have done between the arrest and the court date.
