If you use your own car for business purposes, discuss this with your agent. Many personal auto insurance policies exclude coverage if the vehicle involved in an accident is used mainly for business. A business auto policy provides coverage for autos owned by a business. The insurance pays any costs to third parties resulting from bodily injury or property damage for which your business is legally liable, up to the policy limits. Depending on what kind of coverage you buy, the insurance may pay to repair or replace your vehicle because of damage resulting from accidents, theft, flooding and other events.
