(This post applies only to persons over the age of 21 or who are not on probation for a previous DUI.)
What should you do if you are stopped while driving a vehicle and the cop suspects you are driving under the influence of alcohol? The laws that govern a DUI stop provide you with less rights than you would have during an ordinary police contact. The premise underlying this diminished due process on a DUI stop is that driving on California roadways is a privilege, not a right, and therefore you are not afforded all the protections provided in the Constitution. But you still have certain rights when you are stopped on suspicion of DUI.
When you are pulled over for suspected driving under the influence, you are considered detained and you are not free to go. Even though the officer has not yet read you your “Miranda rights,” which is not required until you are arrested, your right to remain silent is triggered at the time of the detention. You must provide the officer with your driver license (and car registration) but beyond that you do not have to answer the officer’s questions. As with any police detention or arrest, your best approach is to be politely cooperative and provide your identification, but to let the officer know that you wish to remain silent.
