When you’re stopped for a DUI stop, stay calm and pull over safely. Turn on your hazard lights, keep your hands visible on the steering wheel, and wait for the officer to approach. Avoid making sudden movements or reaching for anything until asked.
Be respectful and provide your license, registration, and insurance when requested. You have the right to remain silent, and you don’t have to answer questions like “Have you been drinking?” Politely say you prefer not to answer without a lawyer present.
You can refuse field sobriety tests in many states, but refusing a breath or chemical test may lead to penalties under implied consent laws. Stay polite, avoid arguing, and contact a DUI lawyer as soon as possible if you’re arrested.

What Triggers a DUI Stop?
Police officers stop drivers for DUI when they observe signs of impaired driving. A DUI stop often begins with a traffic violation or unusual driving behavior. Officers look for actions that suggest the driver may be under the influence of alcohol or drugs.
Common signs that trigger a DUI stop include:
- Swerving across lanes or failure to stay in one lane
- Driving too slowly or too fast without reason
- Sudden stops or failure to stop at signs or lights
- Drifting over the road’s centerline or edge
- Delayed response to traffic signals
- Driving at night with headlights off
These behaviors give police “reasonable suspicion” to pull over a driver. Reasonable suspicion is a legal standard that allows an officer to investigate further based on specific and clear signs of possible lawbreaking.
Once an officer sees enough signs, they activate their lights and begin the stop. From that moment, the officer starts observing everything: how the driver pulls over, body movements, speech, smell, and more. These early signs help the officer decide if further testing is needed.
How Should You React When Pulled Over?
When an officer signals you to stop, respond immediately by pulling over to a safe, well-lit area. Use your turn signal, slow down steadily, and stop your car completely. Turn off the engine, lower your window, and place both hands on the steering wheel where the officer can see them.

Stay calm and avoid sudden movements. Wait for the officer to speak first. When asked, provide your driver’s license, vehicle registration, and proof of insurance. If these items are in a glovebox or bag, tell the officer before reaching for them to avoid misunderstandings.
Speak clearly, remain polite, and do not argue. Everything you say and do can be used as evidence. Keep your answers brief. If the officer asks if you’ve been drinking, you can say, “I prefer not to answer.” This protects your legal rights without being rude.
What Are Your Rights at a DUI Stop?
During a DUI stop, you have the right to remain silent. You do not have to answer questions like whether you’ve been drinking, where you were coming from, or how much you had to drink. Politely say you choose not to answer without a lawyer present.
You also have the right to refuse field sobriety tests in most states. These include tests like walking in a straight line or standing on one leg. Refusing them may lead to suspicion, but they are not legally required in many areas.
However, refusing a chemical test—such as a breath, blood, or urine test—can lead to penalties under implied consent laws. These can include license suspension or fines, even if you’re not convicted. Knowing which rights apply in your state helps you make better choices during the stop.
Should You Take Field Sobriety Tests?
Field sobriety tests are physical tasks police use to check for signs of impairment. Common tests include walking in a straight line, standing on one leg, and following a moving object with your eyes. These tests help the officer decide if there is probable cause for arrest.
In many states, you can legally refuse field sobriety tests. They are not the same as chemical tests and are not required by law. Officers may still arrest you if they see other signs of intoxication, but refusing the tests can limit the evidence used against you.
Refusing may raise suspicion, but these tests are often subjective and can be failed even when sober due to medical or balance issues. Always respond politely and calmly, and consider saying, “I respectfully decline.” Knowing this helps protect your legal position.
What Happens During a Breath or Chemical Test?
After a DUI stop, an officer may ask you to take a breath, blood, or urine test to measure your blood alcohol concentration (BAC). These are known as chemical tests and are different from roadside field sobriety tests. Most states require you to take them under implied consent laws.
Implied consent means that by driving, you’ve agreed to BAC testing if lawfully arrested for DUI. Refusing a chemical test can lead to automatic penalties like license suspension, even if you aren’t convicted in court. Some states add fines or longer suspensions for a refusal.
There are two types of breath tests: the preliminary breath test (PBT) at the scene and the official breathalyzer test at the station. You may be allowed to refuse the roadside PBT, but not the official test. Always ask if the test is mandatory under your state law.
How Should You Behave With the Officer?
Your behavior during a DUI stop can strongly affect what happens next. Stay calm, respectful, and cooperative, even if you choose to use your legal rights. Arguing, acting nervous, or being rude can increase suspicion and may be used against you in court.
Avoid sudden movements, don’t talk over the officer, and don’t lie. If you feel nervous, take slow breaths and answer only what’s necessary. You can say, “I would like to speak to a lawyer” if the questions go beyond basic information.
Everything you say and do may be recorded on video or reported in the officer’s notes. Staying polite and quiet helps protect your rights and leaves fewer chances for your words or actions to be misinterpreted.
What Happens After the DUI Stop?
If the officer believes you are under the influence, you may be arrested. You’ll be handcuffed, taken to a police station, and booked. Booking includes taking your fingerprints, photo, and personal details. Your car may be towed or impounded.
After arrest, you might be held in jail until bail is posted or until your court hearing is scheduled. In most states, you’ll receive a notice of license suspension and a date for your first court appearance, also known as an arraignment.
It’s important to contact a DUI lawyer as soon as possible. A lawyer can help you understand deadlines for requesting a hearing, challenge the license suspension, and prepare a defense. Acting quickly improves your chances of a better outcome.
