What form must evidence of public liability insurance take?

The correct choice, a certificate of insurance, serves as proof that an individual or organization carries public liability insurance. This document is typically issued by the insurance company and outlines the coverage, limits, effective dates, and the parties involved. It is a concise and easily verifiable form of evidence, making it the preferred method for demonstrating insurance coverage in various legal and business situations.

While a written agreement may outline the terms of insurance, it does not serve as direct proof of coverage. A policy document provides the detailed terms and conditions of the insurance policy, which is more comprehensive than necessary for demonstrating coverage. An application form, on the other hand, is simply a request for insurance and does not confirm that coverage has been granted. Therefore, the certificate of insurance stands out as the definitive proof of public liability insurance.
