Unsatisfactory Safety Rating; Revocation of Operating Authority Registration; Technical Amendments

Summary: This final rule repromulgates in the Code of Federal Regulations a statutory requirement that FMCSA revoke the operating authority registration of a for-hire motor carrier for failure to comply with safety fitness requirements; if the Agency determines that a motor carrier is ``Unfit'' based on its Safety Fitness Determination procedures, the Agency must revoke the carrier's operating authority registration. Unfit motor carriers are prohibited from operating in interstate commerce, and the Secretary of Transportation is required by statute to revoke their operating authority registration. This final rule also repromulgates several technical provisions and makes non-substantive administrative changes. These changes, initially adopted as part of the April 5, 2010, final rule entitled ``Electronic On-Board Recorders for Hours-of-Service Compliance,'' are necessary because, for reasons unrelated to this final rule, the United States Court of Appeals for the Seventh Circuit invalidated the previous rule.
