(a) The criteria used in a safety audit to determine whether a Mexico-domiciled carrier exercises the necessary basic safety management controls are specified in appendix A to this part.

(b) If the FMCSA determines, based on the safety audit, that the Mexico-domiciled carrier has adequate basic safety management controls, the FMCSA will provide the carrier written notice of this finding as soon as practicable, but not later than 45 days after the completion of the safety audit. The carrier's Certificate of Registration will remain provisional and the carrier's on-highway performance will continue to be closely monitored for the remainder of the 18-month provisional registration period.

(c) If the FMCSA determines, based on the safety audit, that the Mexico-domiciled carrier's basic safety management controls are inadequate, it will initiate a suspension and revocation proceeding in accordance with §385.111 of this subpart.

(d) The safety audit is also used to assess the basic safety management controls of Mexico-domiciled applicants for provisional operating authority to operate beyond United States municipalities and commercial zones on the United States-Mexico border under §365.507 of this subchapter.
