So many cops do not understand that, not only do they not NEED to id you just because there is a line for it on their form, but in fact in zero states may they REQUIRE you to id yourself without reasonable suspicion of a crime. Meaning if they don't have articulable facts to suggest you committed, are committing or were about to commit a crime, you don't have to id yourself for any reason. In some states, you dont have to id yourself until they have probable cause of a crime and choose to arrest you. Moreover, if they do have the requisite reasonable suspicion or are arresting you, you are not required to furnish a physical ID. Even if you have it on you, you don't have to provide it. In most states, all you have to do is provide your name and date of birth, though some also require your permanent address as well. You may not be required to id yourself, but even if not, DO NOT LIE about your identity. That is a crime.

A cop may ASK for an id at any time, and you may choose to willingly provide it, but you are not always required to. I see so many videos of police interactions where the person merely spoke to or argued with an officer, or they were a witness to a crime, or they are approached by the police doing something entirely inoccuous like taking pictures or walking around at night or looking suspicious to a neighbor, and the police demand they id themselves or face arrest. This is a violation of your 4th amendment rights. They will pretend that failure to ID without reasonable suspicion is obstruction or breaks failure to id laws. They are wrong and/or lying. Know your rights wherever you are and do not give them up to anyone.
