Safety rating or rating means a rating of “Satisfactory,” “Conditional” or “Unsatisfactory,” which the FMCSA assigns to a motor carrier using the factors prescribed in § 385.7, as computed under the Safety Fitness Rating Methodology (SFRM) set forth in Appendix B to this part and based on the carrier's demonstration of adequate safety management controls under § 385.5(a). A safety rating of “Satisfactory” or “Conditional” is necessary, but not sufficient, to meet the overall safety fitness standard under § 385.5.
(1) Satisfactory safety rating means that a motor carrier has in place and functioning safety management controls adequate to meet that portion of the safety fitness standard prescribed in § 385.5(a). Safety management controls are adequate for this purpose if they are appropriate for the size and type of operation of the particular motor carrier.
