California Code, Public Utilities Code - PUC § 1040

The commission shall, in issuing a certificate pursuant to this article, require the passenger stage corporation to procure, and to continue in effect during the life of the certificate, adequate protection against liability imposed by law upon the corporation for the payment of damages for personal bodily injuries, including death resulting therefrom, protection against a total liability of the corporation on account of bodily injuries to, or death of, more than one person as a result of any one accident, and protection against damage or destruction of property.

The minimum requirements for these assurances of protection against liability shall not be less than the requirements which are applicable to operations of carriers conducted pursuant to the federal Bus Regulatory Reform Act of 1982 (P.L. 97-261), as amended.  1  However, for vehicles designed to carry not more than eight persons, including the driver, the commission shall not require protection against a total liability of the corporation on account of bodily injuries to, or death of, more than one person as a result of any one accident in an amount exceeding seven hundred fifty thousand dollars ($750,000).
