What Are DUI Checkpoints and Why Are They Used? 
A DUI checkpoint is a roadblock set up by law enforcement where all drivers are stopped at a predetermined location. The purpose of these checkpoints is to reduce the number of drivers under the influence of alcohol or drugs. They are a tool used to increase public safety and deter impaired driving. In Tennessee, the law allows for DUI checkpoints to be set up as part of a larger strategy to combat driving under the influence, especially during times when celebrations involving alcohol are common—like during spring break, major holidays, or other festive occasions.
Police officers conducting DUI checkpoints in Chattanooga must follow certain guidelines, which ensure the legality and fairness of the stop. For instance, they must stop all vehicles or stop drivers on a random basis to prevent discrimination. These measures are designed to make the checkpoint fair and transparent for everyone involved.
Understanding Your Rights When Stopped at a DUI Checkpoint
The moment you approach a DUI checkpoint, it’s natural to feel anxious. After all, being stopped by the police can be a stressful experience. However, it’s crucial to understand your rights so that you can respond appropriately. In Tennessee, there are certain things police officers can and cannot do during a DUI checkpoint. Knowing this information can help you avoid unnecessary complications or even legal violations.
What Police Officers Can Do During a DUI Checkpoint
- Request Your Documents: When you stop at the checkpoint, the officer may ask you for your driver’s license, registration, and proof of insurance. You are required to provide these documents upon request. It’s a good idea to have them ready to avoid delays. However, you are not required to provide anything beyond these basic documents.
- Ask You to Perform a Field Sobriety Test: If the officer suspects that you are impaired, they may ask you to participate in a field sobriety test. This test could involve walking a straight line, balancing on one leg, or following an object with your eyes. While these tests are voluntary, refusing them may lead to certain consequences, such as the suspicion of impairment being raised even further.
- Conduct a Breathalyzer Test: If the officer believes that you are under the influence of alcohol, they may ask you to take a breath test using a breathalyzer. In Tennessee, if you are arrested on suspicion of DUI, you are legally obligated to submit to a breath test. Refusing to take the test could lead to a suspension of your driver’s license.
- Search Your Vehicle with Probable Cause: Officers at a DUI checkpoint cannot search your vehicle without a valid reason. If an officer detects the smell of alcohol, marijuana, or any other substance that raises suspicion, they may have probable cause to search your vehicle. However, they cannot search your car without cause or consent unless they have a search warrant or reasonable suspicion.
- Question You About Impairment: The officer may ask you questions such as, “Have you been drinking tonight?” or “How much have you had to drink?” You have the right to remain silent and should keep this in mind when responding. You are not required to answer questions that could potentially incriminate you.
Garth Best was extremely helpful in my case. He explored and explained everything to me clearly and never stopped checking out every option. I am absolutely grateful I chose him as my attorney. Best and Brock are a great choice for representation. Thanks again.

Matt Brock did an outstanding job with my case. Very thorough and knowledgeable attorney, highly recommended. Its very obvious through my interactions with him that he has the experience and knowledge to win in court. I will not go anywhere else. Great job, much appreciated.

What Police Officers Cannot Do During a DUI Checkpoint
- Target You Based on Personal Characteristics: Officers at a DUI checkpoint are not allowed to stop you for reasons such as your race, gender, or any other characteristic. The stop must be random or uniform across the checkpoint. If you believe you were stopped for discriminatory reasons, it’s important to consult with a criminal defense attorney, like the team at Best and Brock, who can help you navigate this situation.
- Keep You at the Checkpoint Longer Than Necessary: Once you’ve shown your identification and the officer has completed their quick check, they must let you go unless there is reasonable suspicion that you are impaired or have committed a traffic violation. You should not be detained for longer than necessary, and if you are, it may be grounds for a legal challenge.
- Search Your Vehicle Without Cause: Unless there is clear probable cause or you give consent, police cannot search your car. For example, if an officer smells alcohol or marijuana, they may have probable cause to search the vehicle. However, they cannot simply search your vehicle because they want to or without a clear reason.
- Force You to Answer Incriminating Questions: The U.S. Constitution grants you the right to remain silent. This means you do not have to answer any questions that might incriminate you. The officer may ask you where you’re coming from or if you’ve been drinking, but you have the right to decline to answer. If you’re unsure about how to proceed, it’s always best to remain polite and ask for a lawyer.
- Conduct a Breathalyzer Test Without Your Consent (Under Certain Conditions): While officers may request you to take a breath test, you are not legally required to submit to it unless you’ve been arrested for DUI. However, refusal to take the test may result in penalties, including a suspension of your driver’s license. Always be aware of the consequences before deciding whether or not to comply.
