Insurance companies will have several options for you if you want to add a primary driver to your insurance policy. You can add more than one named driver. Make sure that all your drivers have a valid driver’s license and a clean driving record.To add them to your policy, simply send in their identification papers, documented proof of your relationship with them, their driving records, and other papers as requested by your provider.If your roommate frequently uses your car but you don’t want them to be listed as one of the drivers under your policy, you can simply exclude them. However, you should make sure they carry insurance of their own.
