A commercial automobile insurance policy is required under most circumstances when the vehicle is used for business purposes and meets certain other requirements. It is not just the registration that determines the requirement for a business automobile insurance policy. Other requirements are ownership by a corporation, use in hauling goods for hire, and gross vehicle weight of the vehicle. Some small trucks can be owned and insured under a personal automobile insurance policy under specific circumstances. .

Commercial automobile insurance policies are not regulated in pricing, as are private passenger policies. There is price competition between insurance companies for good commercial automobile insurance.
