I was looking for where I hid my license the other morning, because I was about to head out on a bike ride. Why do you bring your license, you ask? Riding a bike requires no license. California doesn’t require you to carry ID. I have an ID bracelet in case of emergency, and devices that set off alarms if I crash. These work. Ask me how I know.
Unless…
You are stopped by LEO for something. You don’t have to carry ID unless an officer says that you committed some infraction, in which case you have to show ID. Even if you didn’t commit an infraction, and can show the officer video proving it, not having ID in that case is an infraction. For which you will be written up.
So you don’t need an ID unless you do, in which case not having it is a ticketable infraction.
