Proof of insurance or bond coverage or cancellation shall be on forms E, H and K prescribed by the Commission. The filing of such proof shall constitute acceptance of the minimum terms required by Section 18d-170 of the Law and prescribed in this Part, or higher levels of coverage stated in the policy or set forth on the certificate of insurance, and shall bind the insurance company to those terms. The coverage shall remain in effect until a cancellation form is filed with the Commission or the coverage is superseded by filing a subsequent certificate of insurance.
