Can you pay half of your car insurance and then pay the rest off monthly?

Generally insurance companies don't really mind how you pay as long as you pay. That's a little of a joke. I own an independent agency and from my experience you probably would be better off setting up a monthly payment plan and then pay whatever amount you want when you wish. Each month they will bill you for a minimum payment but also list the balance and you will save the service charges if you pay it off early.
