Reviews. For the purposes of this part:
(1) Compliance review means an on-site examination of motor carrier operations, such as drivers' hours of service, maintenance and inspection, driver qualification, commercial drivers license requirements, financial responsibility, accidents, hazardous materials, and other safety and transportation records to determine whether a motor carrier meets the safety fitness standard. A compliance review may be conducted in response to a request to change a safety rating, to investigate potential violations of safety regulations by motor carriers, or to investigate complaints or other evidence of safety violations. The compliance review may result in the initiation of an enforcement action.
(2) Safety audit means an examination of a motor carrier's operations to provide educational and technical assistance on safety and the operational requirements of the FMCSRs and applicable HMRs and to gather critical safety data needed to make an assessment of the carrier's safety performance and basic safety management controls. Safety audits do not result in safety ratings.
(3) Safety management controls means the systems, policies programs, practices, and procedures used by a motor carrier to ensure compliance with applicable safety and hazardous materials regulations which ensure the safe movement of products and passengers through the transportation system, and to reduce the risk of highway accidents and hazardous materials incidents resulting in fatalities, injuries, and property damage.
(4) Roadability review means an on-site examination of the intermodal equipment provider's compliance with the applicable FMCSRs.
