Final answer:
When stopped by a police officer, be prepared to show ID, vehicle registration, and insurance, and know your Miranda rights, including the right to remain silent and the right to an attorney. An officer may only conduct a frisk if there's reasonable suspicion of a crime. Proof of citizenship should not be required without cause for a stop.
Step-by-step explanation:
When stopped by a police officer, you should be prepared to provide certain information. According to the Miranda Warning, you have the right to remain silent, as anything you say can be used against you in a court of law. You also have the right to an attorney, and if you are unable to afford one, the state will provide you with one.
Furthermore, in situations such as a traffic stop, you are typically required to provide identification, vehicle registration, and proof of insurance. If there is reasonable suspicion that you have committed or are about to commit a crime, as established in Terry v. Ohio, an officer may conduct a frisk for weapons. In cases where there is no cause for a stop, such as speaking with a heavy Spanish accent without having committed a traffic violation, demanding proof of citizenship may relate to potential Fourth Amendment issues
