A Tennessee DUI conviction cannot be diverted, and it cannot be expunged short of a governor's pardon. It follows you. Austin Tomlinson is a Nashville DUI attorney who defends these charges in Davidson County and across Middle Tennessee, and he handles every case personally.

Tennessee law makes it a DUI to drive or be in physical control of a vehicle while impaired, or with a blood or breath alcohol concentration of 0.08% or more. It applies on public roads and also in shopping center lots, apartment complexes and anywhere else the public generally goes.
Two things in that definition surprise people. Physical control does not require the car to be moving. People are charged asleep in a parked car with the keys within reach. And the 0.08 number is only one route to a conviction. The State can also convict on impairment alone with no test at all, which is why so much of what a Nashville DUI attorney does turns on what the officer says he observed.
Tennessee sets mandatory minimums for DUI. Jail time is not optional on paper, though how it is served can often be negotiated. Figures below come from Tenn. Code Ann. § 55-10-402, § 55-10-403 and § 55-10-404.
| Offense | Confinement | Fine | License revoked |
|---|---|---|---|
| First | 48 consecutive hours minimum, up to 11 months 29 days | $350 to $1,500 | 1 year |
| Second | 45 consecutive days minimum, up to 11 months 29 days | $600 to $3,500 | 2 years |
| Third | 120 consecutive days minimum, up to 11 months 29 days | $1,100 to $10,000 | 6 years |
| Fourth Class E felony |
150 consecutive days minimum, up to the Class E felony maximum | $3,000 to $15,000 | 8 years |
| Fifth Class D felony |
150 consecutive days minimum, up to the Class D felony maximum | $3,000 to $15,000 | 8 years |
| Sixth or more Class C felony |
150 consecutive days minimum, up to the Class C felony maximum | $3,000 to $15,000 | 8 years |
A BAC of 0.15% or higher raises the first-offense minimum from 48 hours to 7 consecutive days. A child under 18 in the vehicle adds a separate $1,000 fine and a mandatory minimum 30 days of incarceration on top of the offense-level penalty. A fifth or sixth offense carries the same 150-day floor set for a fourth offender, up to the higher class maximum. Restricted driving privileges can usually be petitioned for during a revocation period under § 55-10-409, with an ignition interlock, but § 55-10-409(a) bars them outright where there is a prior vehicular assault or vehicular homicide conviction, or where the offense seriously injured or killed someone, even on a first conviction.
Every one of these has to hold up. A DUI defense is the work of finding which one does not.
An officer needs reasonable suspicion to pull you over. No traffic violation, no articulable basis, and everything that followed can be suppressed.
If nobody saw you drive, the State has to build physical control from circumstances. Where the keys were, whether the engine was warm, where the car sat.
Impairment is an opinion, and opinions can be cross-examined. The number is a measurement, and measurements have error rates and procedures behind them.
Calibration records, the 20-minute observation period, operator certification, blood draw chain of custody. Any gap is an attack on the number.
Body cam and dash cam get compared against the officer's written basis. Weaving inside your own lane is not a violation. A suppressed stop usually ends the case.
The three standardized tests have specific validated procedures. Administered on a slope, in traffic, in the wrong footwear, or with the instructions rushed, their results lose most of their meaning.
The machine has to be calibrated and certified, the operator trained, and the 20-minute observation period actually observed. GERD, diabetes and residual mouth alcohol all skew results.
Who drew it, what they swabbed the site with, how it was stored, who handled the vial, how long before analysis. Labs have backlogs and backlogs produce errors.
Alcohol keeps absorbing after you stop drinking. A test an hour after the stop may show a level you were not at behind the wheel.
Injuries, inner-ear conditions, fatigue and lawfully taken prescriptions all produce the signs officers are trained to read as impairment.
Driving in Tennessee means you have already consented to a blood or breath test if lawfully arrested for DUI. Refusing is a separate violation from the DUI itself, and it carries its own license revocation, which runs whether or not you are convicted of the DUI. Two things changed here recently. Public Chapter 403, a 2025 act, raised the first-refusal revocation to eighteen months in one specific situation, and it settled a question defendants used to win on.
| Situation | Revocation |
|---|---|
| First refusal, no prior conviction | 1 year |
| First refusal, no prior conviction, where the refusal was of a blood test and the person is suspected of a misdemeanor DUI | 1 year and 6 months § 55-10-407(a)(1)(B), eff. 1/1/2026 |
| Refusal with a prior conviction | 2 years |
| Collision causing serious bodily injury | 2 years |
| Collision causing death | 5 years |
There is a real defense here, and it lives one section over at § 55-10-406(d)(3). An officer must advise you of the consequences of refusing. If that advice was not given, the court has no authority to revoke your license or to order an ignition interlock for the refusal. It is one of the first things worth checking on any refusal case.
No. DUI is excluded from judicial diversion under Tenn. Code Ann. § 40-35-313 and from pretrial diversion under § 40-15-105, and a DUI conviction is on the list excluded from expungement at § 40-32-107(a)(1)(D)(xlv). A DUI charge that is dismissed or tried to an acquittal is a different question, and that one can be expunged under § 40-32-106. Every other route out runs through the charge itself: getting it dismissed, suppressed, or reduced to something that is eligible.
This is the single most important thing to understand about a DUI, and it is why treating a first offense as a minor problem is a mistake. A shoplifting charge handled badly can often be cleaned up later. A DUI conviction is permanent. That changes the math on fighting it.
DUI is closed to both forms of diversion. What veterans and service members should ask about instead is the Davidson County Veterans Treatment Court, which takes part of its docket through a diversion program and part as a condition of probation. Whether it reaches a particular DUI is a question to put to Austin directly, because the answer depends on the charge and on your record.
A DUI is also one of the fastest ways to lose a security clearance or a CDL. If either applies to you, that has to shape the strategy from day one rather than come up at sentencing.
Veterans Defense OptionsA documented service-connected condition carries real weight with a prosecutor and a judge. It has to be raised early and with records behind it.
Treatment and a veteran mentor in place of jail, for veterans the court screens and admits.
Austin maps what a given resolution costs you outside the courtroom before you agree to it.
Choosing a Nashville DUI attorney comes down to who will actually do the work in the file. Here is what that looks like at Patriot Law.
Body cam, calibration logs, the observation period, the lab packet. The defense in a DUI is almost always sitting in the file somebody did not open.
Austin handles the intake, the negotiation and the court dates himself. You are not handed to an associate the week before trial.
You know the number before you hire him, in writing, at no charge.
A first-offense DUI conviction carries a mandatory minimum of 48 consecutive hours, or 7 consecutive days if your BAC was 0.15% or higher. The minimum is mandatory on conviction. How and where it gets served is often negotiable, and avoiding the conviction entirely is the real objective.
There is no universally right answer, which is why the question is better asked before you are ever stopped. Refusing triggers its own revocation under the implied consent law and can be argued to a jury as consciousness of guilt. It also no longer reliably denies the State a sample. Since May 2025, section 55-10-406(d)(4) provides that your refusal is still a violation even if your blood is obtained anyway through a search warrant, court order, exigent circumstances or other lawful means. Making them get a warrant is not a free move. Whichever you did, it is workable. Do not assume refusing saved you or sank you.
Not on the revoked license. In most cases you can petition for restricted driving privileges under Tenn. Code Ann. § 55-10-409, which typically means an ignition interlock and a defined set of permitted destinations such as work, school and treatment. Subsection (a) bars them entirely where the case involved serious injury or death, or where there is a prior vehicular assault or vehicular homicide conviction. Driving on a revoked license is a separate charge and it makes everything else harder.
It happens, but not as a matter of course and not as a favor. A reduction comes from a real weakness in the State's proof: a questionable stop, a test problem, a physical control issue. Prosecutors in Davidson County do not reduce DUIs simply because it is a first offense.
You can still be charged. Tennessee reaches physical control, not just driving, and courts look at factors like where the keys were, whether the engine was running or warm, where the vehicle was located, and your position in it. These cases are frequently defensible, and they are also frequently charged.
A first-offense DUI in General Sessions commonly runs three to six months across several settings. Blood cases take longer because of TBI lab turnaround. Pushing a case fast is rarely in your interest when the lab result has not come back yet.
A conviction does, because it cannot be expunged short of a governor's pardon under § 40-32-107(d). A charge that is dismissed or reduced to an eligible offense can be expunged, but the expungement is a separate filing you have to actually make. That is the strongest practical argument for fighting the charge rather than accepting the first offer.
Each county page covers the court structure, the specialty courts and the local rules of that county. Each city page covers which court actually has your case, how far away it is, and what that city's own court can and cannot do. The areas served page lays all of it out in one place. If your city is not listed, call anyway — these are the places Austin appears most often, not the limits of where he goes.
