DUI Defense

Is It Worth Hiring a DUI Attorney in Tennessee?

What a DUI attorney in Tennessee can and cannot do, what the State has to prove, and the mandatory penalties that apply even on a first offense.

Nobody is required to hire a DUI attorney in Tennessee. You can represent yourself, ask the court about a public defender, or hire private counsel. Whether a private lawyer is worth the cost depends on what the State can prove, what a conviction would carry for you, and what can actually be challenged in your case.

This page lays out those three things plainly. It is general information about Tennessee law, not advice about any specific case.

The short version: a Tennessee DUI conviction carries mandatory jail time, a mandatory loss of your license, and no access to judicial diversion. Those minimums apply to first offenses too. A lawyer cannot change the statute. A lawyer can test whether the State can meet it.

What the State Has to Prove Under § 55-10-401

Tennessee's DUI statute is Tenn. Code Ann. § 55-10-401. It makes it unlawful "to drive or to be in physical control of any automobile or other motor driven vehicle" on a public road, or on premises "generally frequented by the public at large," such as a shopping center or apartment complex parking lot, while any one of the following is true:

Impairment

Under the influence of an intoxicant, marijuana, a controlled substance, a drug, or a combination that "impairs the driver's ability to safely operate a motor vehicle." § 55-10-401(1).

0.08 or More

An alcohol concentration in the blood or breath of "eight-hundredths of one percent (0.08%) or more." § 55-10-401(2).

0.04 in a Commercial Vehicle

An alcohol concentration of 0.04% or more while operating a commercial motor vehicle as defined in § 55-50-102. § 55-10-401(3).

Two details matter more than people expect. First, "physical control" means the State does not always have to prove you were driving. Second, the impairment theory does not require any test number at all. A case can be built on driving behavior, officer observations, and field sobriety tests. The same statute covers prescription medication.

Each of those pieces of evidence has to be gathered lawfully and reported accurately. That is where a defense starts.

What a Tennessee DUI Conviction Carries

The penalties below come from Tenn. Code Ann. § 55-10-402 (jail) and § 55-10-404 (the court ordered driving prohibition). The minimums are mandatory.

Tennessee DUI penalties by offense number
Offense	Minimum jail	Maximum	License prohibition
First offense	48 consecutive hours (7 consecutive days at 0.15% or more)	11 months, 29 days	1 year
Second offense	45 consecutive days	11 months, 29 days	2 years
Third offense	120 consecutive days	11 months, 29 days	6 years
Fourth offense	150 consecutive days	Class E felony range	8 years

Sources: Tenn. Code Ann. § 55-10-402(a) and § 55-10-404(a). A fifth offense is a Class D felony and a sixth or later is a Class C felony under § 55-10-402(a)(5) and (a)(6). Fines, court costs, and treatment costs are not shown.

Several rules sit on top of that table:

Ten year lookback. A prior DUI counts toward your offense number if it occurred within ten years of the new violation. § 55-10-405. A prior vehicular assault or vehicular homicide conviction counts regardless of age.
A child in the car. If a child under 18 was in the vehicle, the sentence "shall be enhanced by a mandatory minimum period of incarceration of thirty (30) days." § 55-10-402(b)(1).
Probation for the balance. After the minimum, the rest of the sentence up to the maximum is served on probation. § 55-10-402(e). A first offense can mean close to a year of supervision.
No judicial diversion. Tenn. Code Ann. § 40-35-313 excludes "driving under the influence of an intoxicant as prohibited by § 55-10-401" from diversion. A guilty plea to DUI is a conviction.

A Refusal Is a Separate Case

Tennessee drivers are "deemed to have given implied consent" to breath and blood testing. Tenn. Code Ann. § 55-10-406. Refusing is not a crime. Under § 55-10-407, a driver found to have refused "is not considered as having committed a criminal offense." It still carries a license revocation:

1 year with no prior conviction
1 year and 6 months with no prior conviction, a suspected misdemeanor DUI, and a refused blood test
2 years with a prior conviction
2 years if the refusal followed a crash with serious bodily injury, and 5 years if someone was killed

That revocation "runs consecutive to the period of license suspension imposed following a conviction" for DUI. A driver who refuses and is then convicted can face both periods back to back. See our page on implied consent refusal for more.

What a DUI Attorney in Tennessee Actually Does

The value of a DUI attorney in Tennessee is not a promise about the result. It is the work of testing each step the State took, in order.

The stop

An officer needs reasonable suspicion to pull a car over. If the stop was unlawful, evidence gathered after it may be challenged.

The arrest

An arrest requires probable cause. Field sobriety tests have standardized instructions and scoring. Video from the cruiser and body camera often shows something different from the report.

The test

Breath instruments have maintenance and observation requirements. Blood draws under § 55-10-406 require a search warrant or exigent circumstances. Chain of custody and lab procedure are reviewable.

The preliminary hearing

In General Sessions, the State must show probable cause. Cross examining the arresting officer under oath locks in testimony early. See how preliminary hearings work and General Sessions vs. Criminal Court.

Negotiation or trial

Some DUI cases are resolved as reckless driving, a Class B misdemeanor under Tenn. Code Ann. § 55-10-205. That depends on the evidence, your record, and the prosecutor. Some cases go to trial.

Your license

A driver prohibited from driving under § 55-10-404 or § 55-10-406 may apply to the trial judge for a restricted license under § 55-10-409. An ignition interlock device is often a condition. Some drivers are ineligible.

Every case turns on its own facts. Any result described on this page is not a prediction or guarantee of the outcome in another matter.

When the Stakes Are Highest

Some facts raise the minimums, add a second proceeding, or reach past the courtroom into your job and benefits.

A prior within ten years

A second offense moves the jail minimum from 48 hours to 45 days. A fourth is a felony.

0.15% or higher

A first offense minimum rises from 48 hours to 7 consecutive days.

A child in the vehicle

Adds a mandatory 30 days to the sentence under § 55-10-402(b)(1).

A crash with injuries

Can change the charge entirely and can make a driver ineligible for a restricted license under § 55-10-409.

A commercial license

The per se limit in a commercial motor vehicle is 0.04%, half the usual threshold.

A clearance or military career

A DUI can surface in a security clearance review or VA matter. See security clearance and benefits.

Public Defender or Private Attorney

Under Tenn. Code Ann. § 40-14-202, the court "shall then advise the accused with respect to the accused's right to counsel." If the court finds you indigent, it "shall appoint to represent the accused either the public defender, if there is one for the county, or, in the absence of a public defender, a competent attorney licensed in this state."

Public defenders are licensed attorneys who try DUI cases every week. The tradeoff is caseload and choice. You do not pick your appointed lawyer, and appointment depends on the court's finding about your finances. With private counsel, you choose who handles your case and how you reach them.

If you are weighing whether to hire a DUI attorney in Tennessee, these questions are fair to ask any lawyer you consider:

Who will appear in court on my case, and who will I talk to between dates?
Will you get the video and the breath or blood test records before advising me on a plea?
What does the fee cover: General Sessions only, or Criminal Court and trial too?
How will you handle the license side, including a restricted license?

Frequently Asked Questions

Do I need a lawyer for a first offense DUI in Tennessee?

No law requires one. A first offense DUI in Tennessee still carries a mandatory minimum of 48 consecutive hours in jail under § 55-10-402(a)(1), a one year driving prohibition under § 55-10-404, and no access to judicial diversion. Whether a lawyer is worth the cost depends on the evidence and what a conviction would mean for you.

Can I get judicial diversion for a DUI in Tennessee?

No. Tenn. Code Ann. § 40-35-313 excludes driving under the influence under § 55-10-401 from judicial diversion. A guilty plea to DUI results in a conviction.

Is refusing a breath or blood test a crime in Tennessee?

No. Under § 55-10-407, a driver found to have violated the implied consent law is not considered to have committed a criminal offense. The refusal still carries a license revocation, one year for a driver with no prior conviction, and it runs consecutive to any DUI suspension.

How far back do prior DUIs count in Tennessee?

Ten years. Under § 55-10-405, a prior DUI within ten years of the new violation makes you a multiple offender. A prior conviction for vehicular assault or vehicular homicide counts no matter how old it is.

Can I get a public defender for a DUI?

If the court finds you indigent, § 40-14-202 requires it to appoint the public defender, or another licensed attorney where there is no public defender. The court makes that determination based on your finances.

Can a DUI be reduced to reckless driving in Tennessee?

Some DUI cases are resolved as reckless driving, a Class B misdemeanor under § 55-10-205. Whether that is available depends on the evidence, your record, and the prosecutor. No lawyer can promise it.
