As a business owner, you need the same kinds of insurance coverages for the car you use in your business as you do for a car used for personal travel -- liability, collision and comprehensive, medical payments (known as personal injury protection in some states) and coverage for uninsured motorists. In fact, many business people use the same vehicle for both business and pleasure. If the vehicle is owned by the business, make sure the name of the business appears on the policy as the "principal insured" rather than your name. This will avoid possible confusion in the event that you need to file a claim or a claim is filed against you.
Unfortunately for every business owner, the chances of getting sued have dramatically increased in the last decade. General Liability insurance can prevent a legal suit from turning into a financial disaster by providing financial protection in case your business is ever sued or held legally responsible for some injury or damage.
