License California Sfchronicle And Driver's com Look Procedure A - If you don’t own a car, there is no need to carry insurance. Cars are insured, not people.
If you own a registered car, you will need to carry insurance on that car even if it is never driven, or not driven by you. The fact that you have or don’t have a driver’s license has no bearing on your owning a car. The car is insured, not the person in the US.
If you don’t want to drive anymore, then go into your local DMV, tell them you wish to cancel your license and get a state ID. They will punch a hole in your license - cancelled as of that moment, take it out of the system and apply for a state ID, which you will likely get in the mail in a few weeks. In the meanwhile, your punched driver’s license will suffice for ID purposes, but no longer for driving a car.
