Getting pulled over by the police can be a nerve-wracking experience, whether it’s your first time or you’ve been through it before. In Tennessee, traffic stops are a routine part of law enforcement’s effort to ensure road safety, but they can quickly escalate—especially if an officer suspects impaired driving or other criminal activity. Knowing what questions police are likely to ask during a traffic stop and how you can lawfully respond can help protect your rights and avoid unintentional self-incrimination.
At Barnes & Fersten, we’ve helped countless clients in Knoxville and across East Tennessee navigate the legal fallout of traffic stops. In this post, we’ll walk you through some of the most common questions drivers face during a stop and explain what those questions mean from a legal standpoint—so you can be better prepared if it happens to you.
1. “Do you know why I pulled you over?”
Why They Ask:
This question may sound polite or conversational, but it’s a subtle investigative tactic. Law enforcement officers are trained to ask open-ended questions that may prompt a driver to admit guilt. If you respond with something like, “Yeah, I was going a little fast,” you’ve just made a voluntary admission, which can be used against you in court or to justify issuing a citation.
Even if you’re not sure what you did wrong, many people instinctively try to guess or apologize, which can also be interpreted as an admission.
What the Law Says:
There’s no legal requirement for you to answer this question, and you’re under no obligation to speculate about your own wrongdoing. It is important to note that routine roadside questioning is usually not custodial, so Miranda warnings aren’t required—and what you volunteer can be used against you.
How to Respond:
A polite, non-committal answer protects your rights without being confrontational. For example:
“I’m not sure, officer. How can I help?”
This keeps the conversation respectful while avoiding any unintended admissions. It’s important to remain calm and courteous, even if you feel the stop was unjustified.
Pro Tip from a Defense Attorney:
Admissions made at the roadside—even before an arrest—can be used as evidence. It’s always better to say less and protect your rights than to say something that could hurt your case later. Officers are required to cite-and-release you, meaning write you a ticket and let you go on your way unless they acquire specific and articulable facts, more than a mere hunch known as reasonable suspicion of an additional crime to prolong the stop. The more information you provide, the greater the chance of an officer lawfully prolonging the stop. While an officer may prolong the stop regardless, it provides your attorney with a potential legal defense if officers lack important and necessary information to extend the cite-and-release.
2. “Where are you coming from? Where are you headed?”
Why They Ask:
These questions may seem casual, but they often serve a deeper investigative purpose. Officers ask about your travel plans to gauge your behavior, observe your responses for nervousness or inconsistency, and potentially identify suspicious activity.
Your answers can be used to justify further questioning or even a search—particularly if your explanation conflicts with visible evidence (like luggage, multiple passengers, or a strong odor of alcohol or marijuana).
What the Law Says:
You are not legally required to answer questions about where you’re coming from or going. The Fifth Amendment gives you the right to remain silent and avoid self-incrimination. While it’s often best to stay polite, you can choose not to answer without breaking the law.
How to Respond:
If you’re not comfortable answering or think your answer could be used against you, it’s okay to politely decline:
“I’d prefer not to answer any questions about my travel.”
Alternatively, if you feel safe doing so and have nothing to hide, you may answer briefly and truthfully—but remember, even small inconsistencies may be used as a basis for further action. Additionally, if you state you are coming from a friend’s house, a bar, a restaurant, it opens the door to prolonging the questioning about how much you have had to drink and additional suspicion.
Pro Tip from a Defense Attorney:
Law enforcement may try to build reasonable suspicion based on your responses to seemingly simple questions. If you’re unsure, it’s often safer to say less. Being respectful but firm about your rights can help avoid escalating the situation.
3. “Have you been drinking tonight?”
Why They Ask:
This question is a critical turning point in many traffic stops, especially those occurring at night or near bars, restaurants, or events. It’s designed to assess whether the officer should begin a DUI investigation. Even a small admission—like saying you had “just one beer”—gives the officer a reason to investigate further and possibly conduct field sobriety tests or a breath test.
What the Law Says:
You are not required to answer this question. The Fifth Amendment protects you from self-incrimination. Anything you say can—and likely will—be used against you if you’re charged with DUI or any related offense.
How to Respond:
While it may feel natural to try to explain or downplay alcohol use, this often backfires. A respectful way to assert your rights is:
“I’d rather not answer any questions without an attorney present.”
This response protects your legal position without being aggressive.
What Happens If You Admit to Drinking?
Even a modest admission can lead to further testing, including:
- Field sobriety tests
- A preliminary breath test
- Arrest and transport for a chemical test
Officers in Tennessee are trained to use these steps to establish probable cause for a DUI arrest. Sure, an officer may continue with the tests when you mention not answering questions without an attorney or that you have not drank, but it provides less evidence against you.
Pro Tip from a Defense Attorney:
Never lie to police, but you also don’t have to help them build a case against you. Staying quiet and requesting a lawyer is not an admission of guilt—it’s exercising your rights.
4. “Have you taken any drugs or prescription medications today?”
Why They Ask:
Law enforcement in Tennessee is trained to recognize signs of drug-impaired driving—not just from illegal substances, but also from legal prescription and even over-the-counter (OTC) medications. This question helps the officer determine whether to begin a DUI investigation. Even legally prescribed medications—like Ambien, Xanax, or painkillers—can impair driving ability and lead to criminal charges if they affect your performance behind the wheel.
What the Law Says:
Tennessee’s DUI laws (TCA § 55-10-401) make it illegal to drive “under the influence of any intoxicant, marijuana, controlled substance, controlled substance analogue, drug, substance affecting the central nervous system.” This includes legal substances if they impair your ability to operate a vehicle safely.
You are not required to answer questions about drug use—including medications. This is protected under the Fifth Amendment, just like questions about alcohol consumption.
How to Respond:
You can respectfully decline to answer without making an admission:
“I’m not comfortable answering questions without a lawyer.”
Even a statement like “I took my allergy meds earlier” could lead to further questioning or a drug recognition evaluation.
What Happens If You Admit to Taking Medications?
An officer may:
- Call a certified Drug Recognition Expert (DRE) to evaluate you.
- Request a blood or urine test.
- Arrest you if they believe you’re impaired, even without a positive test.
Pro Tip from a Defense Attorney:
Many people assume that because a medication is prescribed or over-the-counter, it’s safe to drive after taking it. But Tennessee law doesn’t distinguish between legal and illegal drugs when it comes to impairment. Always be cautious—and don’t volunteer information that could lead to a DUI charge.
5. “Can I search your vehicle?”
Why They Ask:
When an officer asks to search your vehicle, it typically means they don’t yet have probable cause or a legal justification to do so without your consent. They’re hoping you’ll voluntarily allow the search, which makes any evidence found admissible in court—even if it’s unrelated to the reason for the stop.
Requests like this often arise if the officer smells marijuana, sees suspicious items, or if your answers to earlier questions raised concerns.
What the Law Says:
Under both the U.S. Constitution and Tennessee law, you have the right to refuse a vehicle search unless:
- The officer has probable cause (e.g., visible contraband or the smell of drugs),
- You’re being arrested and the vehicle is being impounded, or
- The search is part of a lawful inventory or safety check.
Consenting to a search waives that protection.
How to Respond:
You can clearly but respectfully refuse:
“I do not consent to a search.”
This is your legal right, and it cannot be used as evidence of guilt. Be calm and firm—do not physically resist if the officer proceeds anyway, as that could result in additional charges.
What If They Search Anyway?
If the officer searches your car without consent or a warrant, and without a valid exception, your attorney can challenge the search later in court through a motion to suppress evidence.
Pro Tip from a Defense Attorney:
Even if you believe you have nothing to hide, consenting to a search is risky. Legal or prescription medications, objects left by passengers, or even cash can be misinterpreted by police and lead to serious charges.
6. “Would you mind stepping out of the vehicle?”
Why They Ask:
When an officer asks—or orders—you to step out of your vehicle, it typically signals that the stop is escalating. This request is common in suspected DUI stops or situations where the officer wants to conduct field sobriety tests or search for weapons.
While it may feel intrusive or alarming, the U.S. Supreme Court (in Pennsylvania v. Mimms, 1977) held that officers may legally order a driver (and in Maryland v. Wilson, 1997, even passengers) to exit the vehicle during a lawful traffic stop for officer safety.
What the Law Says:
You must comply if you’re asked to step out of the vehicle during a traffic stop. Refusing to do so can lead to additional charges such as obstruction or resisting.
However, stepping out of the car does not mean you’ve consented to a search or admitted guilt.
How to Respond:
Stay calm and follow the instruction without sudden movements. You can say:
“Sure, officer,”
or
“I’m stepping out as requested.”
Once out of the vehicle, you are still under the protections of the Fourth and Fifth Amendments. You are not required to answer further questions or perform voluntary field sobriety tests (more on that next).
Pro Tip from a Defense Attorney:
Comply physically, but continue to assert your rights verbally. If you’re being detained or questioned further, you can ask:
“Am I free to leave, or am I being detained?”
This helps clarify whether you’re still involved in a routine stop or now part of a criminal investigation.
7. “Will you take a field sobriety test or breath test?”
Why They Ask:
This question is a critical part of a DUI investigation. If an officer suspects you’re impaired, they may ask you to perform field sobriety tests or take a preliminary breath test on the roadside. These tests are used to help the officer establish probable cause for a DUI arrest.
What the Law Says in Tennessee:
- Field Sobriety Tests:
These tests—like the walk-and-turn, one-leg stand, and horizontal gaze nystagmus—are not legally required. You can refuse to perform them without direct legal penalties. However, the officer may still arrest you if they believe they have enough cause based on your behavior or driving. - Preliminary Breath Test (PBT):
The small, handheld breathalyzer used on the roadside is also voluntary. Refusing it does not trigger automatic penalties under Tennessee law. These tests also cannot be used against you in court. - Post-Arrest Chemical Tests (Blood/Breath/Urine):
Tennessee’s Implied Consent Law (TCA § 55-10-406) comes into play after an arrest. Refusing can lead to license consequences and a separate implied consent citation—but those issues must still be proven and resolved in court or at an administrative hearing. Officers can also seek a warrant for a blood draw.
Our Recommendation:
We recommend refusing roadside field sobriety tests and breath tests. If you are arrested, we generally recommend refusing the evidentiary breath/blood test as well. Yes, you may be cited for an implied consent violation, but that fight happens later—and taking the test hands the State hard numbers or video-scored “clues” that make the DUI case stronger. Our DUI attorneys can challenge the stop, the expansion of the stop, probable cause, and any implied-consent allegation in court.
How to Respond:
If asked to perform field sobriety tests or take a breathalyzer, you can respectfully decline:
“I’d prefer not to take any tests without speaking to an attorney.”
If you’re arrested and taken to the station for a chemical test, you must make a decision carefully. Refusal has consequences, but the results of a test can also be incriminating.
Pro Tip from a Defense Attorney:
Field sobriety tests are subjective and can be failed even when sober—especially if you’re tired, anxious, overweight, or have medical conditions. Politely refusing may be in your best legal interest, especially if the stop appears to be a fishing expedition.
What to Do If You're Arrested During a Traffic Stop in Tennessee
Even a routine traffic stop can escalate quickly into an arrest—especially in cases involving suspected DUI, outstanding warrants, or illegal items in the vehicle. If you’re arrested, what you do next can make a major difference in the outcome of your case.
Here’s what you should—and shouldn’t—do if you’re taken into custody during a traffic stop in Tennessee:
1. Stay Calm and Compliant
Being arrested is stressful, but resisting—verbally or physically—can lead to additional charges like resisting arrest or obstruction. Keep your hands visible, follow instructions, and avoid sudden movements. Most importantly, do not argue or attempt to talk your way out of it at the scene. Save that for your DUI defense attorney.
2. Clearly Invoke Your Right to Remain Silent
Once arrested, you have the right to remain silent. You should clearly and verbally invoke this right by saying:
“I’m invoking my right to remain silent and I want to speak with a lawyer.”
After that, stop talking. Do not answer questions, try to explain your side, or fill the silence. Officers are trained to keep you talking—and anything you say can be used against you.
3. Do Not Consent to Searches
Even after arrest, officers may ask for permission to search your vehicle, phone, or personal belongings. You can and should continue to say:
“I do not consent to any searches.”
This protects your rights—even if they proceed with a search anyway. Your attorney may later be able to challenge it in court.
4. Don’t Talk to Other Inmates About Your Case
If you’re held in custody, anything you say to other inmates or on jail phones may be recorded and used against you. Be cautious and say nothing about your case until you’ve spoken with your lawyer.
