Tennessee Implied Consent Law
Under Tennessee implied consent law, refusing is its own violation with its own license revocation, and it can be decided at your very first court date rather than whenever the DUI resolves. Most of what is published about this is now out of date.
Two Separate Problems From One Traffic Stop
Driving in Tennessee means you have already given implied consent to breath or blood testing under § 55-10-406(d)(1). A violation happens where the operator is placed under arrest, is asked by an officer to submit, is advised of the consequences of refusing, and then refuses. The consequence is a license revocation that applies even if the DUI itself is dismissed.
People come in thinking they have one case. They have two, and the second one is frequently ignored until the license is already gone.
This Can Be Decided at Your First Appearance
Section 55-10-406(d)(4) sets two tracks. If the State moves for it, the refusal is decided at the same time and by the same court disposing of the DUI. If the State does not move, it is decided at your first appearance or preliminary hearing in general sessions court, and no later than the case being bound over to the grand jury.
Why That Matters More Than It Sounds
The common assumption is that the refusal gets sorted out whenever the DUI does, months later. On the second track it does not. It can be resolved at the first court date, which for many people arrives before they have hired anyone, before any discovery has been requested, and before anyone has checked whether the advisement was actually given.
That is the practical argument for getting counsel in early on a refusal case. The defense on the revocation is usually sitting in body camera footage that nobody has pulled yet, and the window to use it can close at a hearing that feels routine.
How Long the Revocation Runs
Section 55-10-407 sets the periods. A first violation is one year, with one narrow exception effective January 1, 2026 that raises it to eighteen months. That exception is considerably narrower than most published summaries suggest.
| Situation | Revocation |
|---|---|
| First violation, no prior conviction | 1 year § 55-10-407(a)(1)(A) |
| First violation, no prior conviction, and suspected of a misdemeanor DUI, and the refusal was of a blood test | 1 year and 6 months § 55-10-407(a)(1)(B), eff. 1/1/2026 |
| Violation with a prior conviction | 2 years § 55-10-407(a)(2) |
| Collision causing serious bodily injury | 2 years § 55-10-407(a)(3) |
| Collision causing death | 5 years § 55-10-407(a)(4) |
The second row has three conditions and all of them have to be true. No prior conviction, suspicion of a misdemeanor violation of § 55-10-401, and a refusal of a blood test. A first-time refusal of a breath test does not meet the third condition and remains a one-year revocation. A great deal of what is currently published flattens this into "first refusal is now eighteen months," which is not what the statute says.
It Can Also Stack Rather Than Overlap
Under § 55-10-407(c), the refusal revocation runs consecutive to a license suspension imposed after a § 55-10-401 conviction where the court finds the implied consent violation and also finds a conviction or juvenile adjudication within the previous five years for implied consent, underage driving while impaired, the open container law, or reckless driving where the charged offense was DUI.
For someone in that position the two periods are served back to back rather than at the same time, which is a materially different amount of time off the road than the table alone suggests.
What Public Chapter 403 Changed
Tennessee's 2025 Public Chapter 403 reworked implied consent. Three of its provisions took effect May 5, 2025 and the revocation change took effect January 1, 2026. Advice written before those dates is describing rules that no longer apply.
A Warrant Draw No Longer Defeats the Refusal Charge
Section 55-10-406(d)(4) now provides that the refusal "is a violation of subdivision (d)(1), even if the operator's blood sample is obtained pursuant to a search warrant, court order, exigent circumstances, or other lawful means."
The old calculation was that refusing at least kept a number away from the State, and you traded a revocation for that. That trade is gone. Whether a revocation is actually imposed still depends on the court finding the violation, and § 55-10-406(d)(3) removes the court's authority to revoke at all where the advisement was not given. But the refusal no longer stops being a violation just because the blood came in another way.
Oral Fluid Tests Are Now Authorized and Admissible
New § 55-10-406(b)(3) permits oral fluid testing on the operator's consent, on a search warrant, incident to a lawful arrest for a listed offense, or without consent where exigent circumstances to the warrant requirement exist. New subsection (j)(2) makes the result admissible in evidence at trial.
This is a category of evidence that did not exist in Tennessee DUI practice two years ago and that most people have never heard of. If an oral fluid test was taken in your case, how it happened and which of those four circumstances applied is worth examining closely.
The Officer Has to Tell You What Refusing Costs
Where the operator is not advised of the consequences of refusing, § 55-10-406(d)(3) provides that the court "shall not have the authority to suspend the license of an operator or require the operator to operate only a motor vehicle equipped with a functioning ignition interlock device" for the violation.
It is the first thing worth checking on any refusal case, and it is checkable. Body camera footage, the officer's report and the implied consent form either show the advisement or they do not. This is not a matter of competing recollections in the way most roadside disputes are.
-
Was There an Arrest First
The statute frames the request as following an arrest. The sequence of what happened, and when, is part of the analysis rather than a technicality.
-
Was the Advisement Actually Given
Not whether a form existed. Whether you were advised. Video answers this better than anyone's memory does, which is a good reason to get footage requested early, before retention schedules do their work.
-
Was It a Refusal, or Confusion
People ask for a lawyer, ask questions, say they cannot produce enough breath, or agree after initially hesitating. Whether a given sequence amounts to a refusal is a real question and not always the one the report answers.
-
Which Test Was Refused
Where the other two conditions of § 55-10-407(a)(1)(B) are met, no prior conviction and a suspected misdemeanor DUI, this is what separates twelve months from eighteen. Where the report does not say which test was refused, there is a real argument that the State has not established the third condition.
You Can Beat the DUI and Still Lose Your License
The revocation attaches to the refusal rather than to the DUI conviction, so a DUI that is dismissed, reduced or acquitted does not by itself undo it. There is one statutory exception, and it is worth knowing about because it has to be asked for.
| The DUI charge | The implied consent violation | |
|---|---|---|
| What it is about | Whether you drove impaired or over the limit | Whether you refused a lawfully requested test after being advised |
| Main consequence | Jail minimums, fines, a permanent conviction | License revocation |
| When it gets decided | When the case is disposed of | The same time, if the State moves. Otherwise at first appearance or preliminary hearing, no later than bind-over |
| If the DUI goes away | No conviction | The refusal is still its own violation |
The Exception: a Bad Stop
Section 55-10-407(b) provides that where a license is already suspended for an implied consent violation, the court disposing of the underlying offense may order the Department of Safety to reinstate the license if the suspension arose from the same incident and the offense "is dismissed by the court upon a finding that the law enforcement officer lacked sufficient cause to make the initial stop of the driver's vehicle."
So a DUI dismissed for lack of reasonable suspicion to stop is the one scenario where winning the DUI can reach the revocation. It is discretionary and it has to be requested. The court may order reinstatement. It does not have to, and it will not do it on its own.
Tennessee Implied Consent Law FAQ
Is a first refusal in Tennessee one year or eighteen months?
One year, unless three things are all true. Section 55-10-407(a)(1)(B) applies eighteen months only where the person has no prior conviction, is suspected of a misdemeanor violation of section 55-10-401, and refused a blood test. A first-time refusal of a breath test is still one year. That provision took effect January 1, 2026.
When does the refusal get decided?
Either at the same time and by the same court disposing of the DUI, if the State moves for it, or otherwise at your first appearance or preliminary hearing in general sessions court, no later than the case being bound over to the grand jury. On that second track it can be resolved at your very first court date, which is a reason not to walk into that hearing without having looked at the discovery.
They got my blood with a warrant anyway. Does the refusal still count?
Yes. Since May 2025, section 55-10-406(d)(4) provides that the refusal is a violation even if the blood sample is obtained through a search warrant, court order, exigent circumstances or other lawful means. Advice written before that date often assumed refusing kept the sample away from the State, and that assumption no longer holds. Whether a revocation is imposed is still for the court to determine.
What if the officer never told me what refusing would do?
Then the revocation may not be available at all. Section 55-10-406(d)(3) provides that where the operator is not advised of the consequences, the court has no authority to suspend the license or to require an ignition interlock for the violation. It is the first thing to check, and body camera footage usually answers it.
What is an oral fluid test and can they make me take one?
It is a newer testing method Tennessee authorized in 2025. Section 55-10-406(b)(3) permits it with your consent, under a search warrant, incident to a lawful arrest for a listed offense, or without consent where exigent circumstances to the warrant requirement exist. The result is admissible at trial under subsection (j)(2). Which of those four circumstances applied in your case is worth examining closely.
If my DUI gets dismissed, does the revocation go away?
Not by itself. The revocation attaches to the refusal rather than to the DUI conviction. There is one exception: under section 55-10-407(b), where the DUI is dismissed on a finding that the officer lacked sufficient cause to make the initial stop, the court disposing of the case may order the Department of Safety to reinstate the license. That relief is discretionary and it has to be asked for.
Can I get a restricted license during an implied consent revocation?
Often yes. Section 55-10-409 allows a court to order a restricted license where a license has been revoked under section 55-10-406, commonly with an ignition interlock and otherwise with defined permitted purposes. The disqualifiers in subsection (a), including a prior vehicular assault or vehicular homicide conviction and seriously injuring or killing someone in the conduct that resulted in a DUI conviction, are written against licenses suspended after a DUI conviction under section 55-10-404. Ask about your specific facts rather than assuming either way.
Should I have refused?
There is no universally right answer, and the calculation is worse than it used to be now that a refusal stands even when the blood is obtained by warrant. Either way there is usually something to work with, but that depends entirely on the facts of your stop. Do not assume refusing saved you, and do not assume it sank you.
Refusal Cases Turn on Details in the File
Whether the advisement was given. Which test was refused. Whether what happened was a refusal at all. Every one of those is answered by the discovery rather than by argument, and the hearing where it gets decided can arrive earlier than people expect.
