Do you have to add your child to your car insurance if they are of legal driving age but don't have a drivers license?

You need to notify your insurance company of all children at or over the age of 15 and let them know of the license status as well. If they get a license of any kind notify your insurance company and give them the license information. If they are not licensed be sure that you do not let them drive the vehicle for any reason. Many insurance policies read that no coverage is provided if you allow someone to drive who you know or should know is not licensed to drive.
