Can You Switch Car Insurance Mid Policy? 
Absolutely you can . That is your choice . But I recommend that prior to canceling your policy to have a quote lined up with another carrier . Going with a lapse of more then 30 days can make your rates much higher . If you canceling because your not happy with your agent but like the carrier you can also call the carrier and they will get you another agent and you can keep you policy . If you are canceling your policy because you no longer have a car and will be getting one in the near future many cases you can go to what is called a non owned policy that covers you if your are driving a car that you do not own for the liability only portion . Call a local agent and discuss your options this will keep your cost down later in the future
