Passengers in a motor vehicle during a traffic stop do not have to show ID to the police unless they are also suspected of a crime. A passenger may politely ask the police officer if they are free to go. If the answer is yes, the passenger may calmly and quietly exit the vehicle and leave the scene. If the passenger is not free to go, then they are being detained and will be required to show ID to the police officer if they are in a Stop and ID state.
