Stopped at a DUI checkpoint in LA County? Know your rights

A calm, informed response matters more than most people realize. What officers can and cannot ask, and what to do next.

If you are stopped at a DUI checkpoint in LA County, you must pull over and generally show your license, registration and proof of insurance, but you keep the right to remain silent and to decline certain tests. Staying calm and polite matters more than anything else you do in the first few minutes.

Checkpoints can feel intimidating, especially after dark. Knowing where your obligations end and your rights begin helps you handle the stop with a clear head.

Do I have to stop at a DUI checkpoint?

Yes. When you reach a properly run checkpoint, you are expected to follow the officers' directions and stop at the designated point. California law generally allows DUI checkpoints when they are conducted under certain safeguards, such as neutral rules for which cars are stopped and limited delays for drivers.

Trying to dodge a checkpoint in an unsafe or unlawful way can give officers a separate reason to pull you over. If you see one ahead and a legal, safe turn is available, you are generally not required to drive into it, but an abrupt or illegal move can create new problems.

What am I required to do at the stop?

Keep it simple and cooperative. Roll down your window, keep your hands visible, and be ready to hand over:

1. Your driver's license
2. Your vehicle registration
3. Your proof of insurance

The officer will usually ask a few quick questions and look for signs of impairment, such as the smell of alcohol or slurred speech.

Do I have to answer questions about drinking?

No. You have the right to remain silent. Questions like "Have you had anything to drink?" are not ones you are required to answer, and anything you say can be used later.

You do not need to be rude or argumentative. A calm, short reply such as "I'd prefer not to answer questions" is generally enough. Do not lie, since false statements can create their own trouble. Staying quiet is different from being untruthful.

Can I refuse field sobriety tests or a breath test?

It depends on the type of test, and the differences matter.

• Field sobriety tests (walking a line, standing on one leg, following a pen with your eyes) are generally voluntary. You can politely decline.
• A roadside breath device used before an arrest is also generally voluntary for most adult drivers. Drivers under 21 or on DUI probation are generally required to take it.
• A chemical test after a lawful arrest is different. California's implied consent law means that by driving, you have agreed to a breath or blood test if you are lawfully arrested for DUI. Refusing can bring separate penalties, including a longer license suspension.

These tests are hard to perform under stress, even when you are completely sober. Nerves, uneven pavement, headlights, medical conditions and footwear can all affect the results.

What happens if I am arrested?

Stay calm, do not resist, and do not argue about the arrest on the roadside. Ask for a lawyer, and then stop answering questions. You can raise every legal issue later, with counsel, where it counts.

Two separate matters can begin after a DUI arrest. One is the criminal case in court. The other is an administrative action by the DMV against your driving privilege. You generally have only 10 days from the date you are given the suspension notice, which is usually the day of the arrest, to request a DMV hearing. Missing that deadline can mean an automatic suspension, so read your paperwork carefully and act quickly.

Write down what you remember as soon as you can: where the checkpoint was, how long you waited, what the officers said, and what tests you were asked to take. Details fade fast, and they can matter when the firm reviews whether the stop and the arrest were handled properly.
