Commercial liability insurance, also known as business liability insurance, is a type of insurance that provides financial protection to businesses in case they're found liable for damages or injuries caused to someone else. This type of insurance covers legal costs, medical expenses, property damage, and other liabilities that can arise in the course of doing business.

Business insurance, on the other hand, is a broader term that encompasses several types of insurance policies designed to protect businesses from different types of risks. It includes commercial liability insurance, as well as other types of coverage, such as property insurance, workers' compensation insurance, and professional liability insurance.
