On the instruction of an authorized enforcement official of a State or of the United States Government, a commercial motor vehicle is required to pass an inspection of all safety equipment required under the regulations issued under section 31136.

The Secretary of Transportation shall prescribe regulations on Government standards for inspection of commercial motor vehicles and retention by employers of records of an inspection. The standards shall provide for annual or more frequent inspections of a commercial motor vehicle unless the Secretary finds that another inspection system is as effective as an annual or more frequent inspection system. Regulations prescribed under this subsection are deemed to be regulations prescribed under section 31136 of this title.

A periodic inspection of a commercial motor vehicle under the Government standards prescribed under subsection (b) of this section or a program described in subsection (c)(1)(B) or (C) of this section that is being enforced shall be recognized as adequate in every State for the period of the inspection. This subsection does not prohibit a State from making random inspections of commercial motor vehicles.

The Government standards prescribed under subsection (b) of this section may not be enforced as the standards apply to the inspection of commercial motor vehicles in a State enforcing a program described in subsection (c)(1)(B) or (C) of this section if the Secretary decides that it is in the public interest and consistent with public safety for the Government standards not to be enforced as they apply to that inspection.

A State receiving financial assistance under section 31102 of this title in a fiscal year may enforce in that fiscal year a regulation on commercial motor vehicle safety adopted by the State as the regulation applies to commercial motor vehicles and operators leased to the Government.
