What Are My Rights During a DUI Stop?

Imagine this: you’re on your way home from a friend’s house after a few glasses of wine. You know your tolerance, and that you are safe to drive based on the amount of alcohol that you had over a period of a few hours. But when you see flashing lights in your rearview mirror, you freeze. What should you do?


DUI stops can be scary. Most people have very few encounters with the police, and may never have been stopped to see if they have committed a crime. The decisions that you make during the course of this stop can affect whether or not you will be charged with the crime of driving under the influence or not. According to a DUI lawyer in Los Angeles, CA, learning your rights is critical to protecting your freedom.


As an initial matter, you are not required to engage in conversation with the police officer. You do need to identify yourself/provide identification, but you do not have to answer questions about where you are coming from or how many drinks you have had. Even answering innocent questions, like how your week is going, could be risky, as the officer wants you to talk in order to smell your breath for alcohol. Politely decline to answer, and wait patiently while the officer runs your license.

You may be asked to take a preliminary alcohol screening (PAS), which may also be referred to as a roadside breathalyzer. There are only two situations where you are required to take a PAS: (1) if you are under the age of 21 and suspected of violating California’s zero tolerance laws; and (2) if you are currently on DUI probation. Otherwise, it is your right to decline to take a PAS without consequence. If you do decide to take a roadside breathalyzer test, the results could be used as a basis for your arrest and may be used against you in court. Importantly, this rule only applies to breath tests before you are arrested. If you refuse a chemical breath or blood test after being arrested on suspicion of DUI, then you will face additional consequences, including the loss of your license and enhanced DUI penalties.

A law enforcement officer may also ask you to perform a series of field sobriety tests, such as walking heel to toe in a straight line and then turning, or standing on one leg while counting and looking down at your foot. There are many reasons why you might fail these tests other than being intoxicated, such as having a disability that makes it hard for you to balance. You are not required under any circumstances to take a field sobriety test. In fact, an experienced DUI lawyer in Los Angeles, CA will generally recommend against doing so. Taking field sobriety tests can only hurt you, as they can be used as justification for your arrest and against you in court.
