Every household goods carrier earning over three hundred fifty thousand dollars ($350,000) in annual gross operating revenue shall, under oath, file annually a report indicating the number, classification, and compensation of all employees and owner-operator drivers hired or engaged during the reporting period. The commission shall submit a copy of the report to the administrator of the carrier`s workers` compensation self-insurance plan if the carrier is self-insured, or to the carrier`s workers` compensation insurer if the carrier`s workers` compensation protection is provided by a policy or policies of insurance. The commission shall not be obligated to undertake an independent investigation of the adequacy of workers` compensation insurance coverage based on the information contained in the report, if the carrier has complied with Section 5135.
