Commercial auto insurance, like your personal auto policy, provides similar coverages such as liability, collision, comprehensive, medical payments (or personal injury protection) and uninsured motorists coverage to your businesses. However, there are also differences between a commercial auto insurance policy and your personal auto policy that may include eligibility, definitions, coverages, exclusions, and limits. This type of business insurance covers a variety of vehicles and is also referred to as commercial car insurance, truck insurance, or fleet insurance.
