I have been wearing a Road ID for several years. I know on the motorcycle the emergency people are not supposed to remove your helmet incase there is a head injury. There are stickers to put on the outside of the helmet. They will also not go through your stuff to look for ID right there on the scene. A fiend had her information on her motorcycle and she went one way and the bike towed another and she was not identified until we started calling hospitals looking for an accident patient. Good advice-take heed.
