What to Do After a DUI Stop in Tennessee — Before You Say Anything

A traffic stop for suspected DUI is designed to gather evidence against you, and most of that evidence comes from what the driver does and says in the first few minutes. You can be polite and cooperative while still protecting yourself. Here is how. If you were arrested after a stop anywhere in the Tennessee Valley, call (865) 935-9558.

First: pull over safely and keep your hands visible

Signal, slow down, and stop in a safe spot. Turn on your interior light if it is dark, keep your hands on the wheel, and stay in the car unless you are asked to step out. None of this is about guilt — it is about starting the encounter calmly, because everything from this point is very likely being recorded by a dash or body camera. That recording can cut both ways, and composure helps you.

Be polite — and understand what you do and don't have to do

You must provide your license, registration, and proof of insurance when asked. You must not lie to an officer. Beyond that, you have rights, and using them is not the same as being uncooperative:

• You do not have to answer questions about where you have been or what you have had to drink. "Have you been drinking tonight?" is not a question you are required to answer. You can respond, politely, that you would prefer not to answer questions without a lawyer. Admissions like "just a couple of beers" are among the most damaging things said in these stops.
• You can decline to perform roadside field sobriety tests. More on this below.
• Stay calm and respectful either way. Declining to answer questions is your right; arguing, fleeing, or being combative only creates new problems and new charges.

Field sobriety tests are voluntary — and less objective than they look

The roadside tests — following a pen with your eyes, walking a straight line heel-to-toe, standing on one leg — are commonly presented as if you have to take them. In practice they are voluntary, and they are graded by the same officer who already suspects you. Your performance can be affected by things that have nothing to do with alcohol: your footwear, an old knee or back injury, your weight and age, the slope and surface of the roadside, passing traffic, cold weather, poor lighting, and plain nerves. People who have had nothing to drink routinely show "clues" on these tests. Politely declining them is something you are allowed to do.

The breath test is a different decision — and Tennessee treats it differently

This is where many people get confused, because there are really two different tests, and the rules are not the same.

• The small handheld device at the roadside (a preliminary breath test) is generally part of the officer's investigation and is treated much like the field sobriety tests.
• The official evidentiary test — the breath or blood test given after an arrest, usually at the station or by a blood draw — falls under Tennessee's implied consent law. By driving on Tennessee roads, you are treated as having consented to this testing, and refusing it triggers a separate driver's-license penalty of its own — one that applies independently of whether you are ever convicted of DUI.

That makes the evidentiary-test decision genuinely consequential in both directions, and it is not one we can make for you in a general article. What matters to know in the moment is that a refusal is not a free pass — it starts its own license case that has to be handled. If you are able to reach a lawyer before that decision, do.

What not to do

• Do not admit to drinking, to how much, or to when — even casually, even to seem cooperative.
• Do not argue, resist, or try to talk your way out of it. You will not, and it makes things worse.
• Do not perform the field tests believing you have to. You generally do not.
• Do not assume the camera is off. Assume every word and movement is being recorded.
• Do not volunteer to explain later on a recorded jail phone, or on social media. Save it for your lawyer.

After the stop: the clock is already running

If you are arrested, a DUI case in Tennessee sets several clocks running at once — including a driver's-license issue that can move faster than the criminal charge. The single most useful thing you can do is get a lawyer involved early, while records can still be requested and options are still open. We walk through the full sequence in our companion article, What Happens After a DUI Arrest in Tennessee.
