Carriers that receive a “Conditional” or “Unsatisfactory” safety rating receive guidance from FMCSA about how they can improve their rating.
A proposed safety rating of “Unsatisfactory” is notice to the motor carrier that the FMCSA has made a preliminary determination that the motor carrier is “unfit” to continue operating in interstate commerce, and that the prohibitions in 49 CFR 385.13 will be imposed after 45 or 60 days, depending on the carrier type, if necessary safety improvements are not made.
