How often you pay your premiums. There's no need to cancel your car insurance after selling a car if you're driving a different vehicle. This information is not an insurance policy, does not refer to any specific insurance policy, and does not modify any provision, limitation or exclusion that is expressly stated in any insurance policy. Since almost every state requires drivers to have liability coverage, you must have a current auto policy with another insurer when you cancel with your current insurer.
Keep in mind that if you're moving to another state, you won't have to change insurers unless your insurance company doesn't offer coverage in that state. I want to add my son to my Progressive car insurance policy, but the projected monthly rate is way out of budget. Depending on your insurance company, you may be able to cancel your policy by calling your insurer or agent.
