how do i self insure my vehicles

A company that is fully insured goes to an insurance company and buys insurance. A company that is self insured does not buy insurance and plans to pay any claims out of the companies "pockets". For instance, if you own a home but choose not to buy home insurance, you are self insured if you should have a fire.
