Each carrier issued provisional operating authority to operate beyond the southern border municipalities and commercial zones will remain in an enhanced safety monitoring period for a minimum of 18 months. During the enhanced monitoring period, FMCSA will conduct a comprehensive compliance review (CR). During the CR, FMCSA reviews all motor carrier, driver, and vehicle requirements for the carrier’s entire operation, including commercial-zone and long-haul operations, to ensure proper safety management controls are in place before granting the motor carrier standard operating authority. The carrier must receive a Satisfactory rating to receive standard operating authority.
