The purpose of a stop and ID law is to allow a police officer to stop you and ask for your name after suspecting you of some criminal activity. These laws allow a police officer to properly investigate this criminal activity. These laws often apply in loitering or prowling circumstances, but they can also apply to other suspected types of unlawful activity. Failing to comply with an officer’s lawful commands can get you arrested, and you could even face jail time for refusing to give the officer your name.
