What is it: Commercial Auto insurance provides coverages such as liability, collision, comprehensive, medical payments and uninsured motorist coverage.

What is it: This insurance protects the business in the case of any incidents involving a vehicle that has been hired by the company to be used for business-related purposes.

Why get it: If your company hires vehicles or allows employees to use their own vehicles for business purposes, you will want to consider this insurance.
