Can You Cancel Car Insurance Over The Phone? 
Depending on your carrier and your state laws . I have many carriers and most of them you can process over the phone . But I do have one carrier that requires a signed request form along with proof that coverage has been placed with another carrier . If you are canceling because your car is not running there are many things you can do to get a refund and still have insurance that covers you if you are driving another car . Talk to an Agent or a carrier and they can do what is best for you .
