(b) If the review determines that the new law or regulation is incompatible with the FMCSRs and/or HMRs, the State must immediately notify the Motor Carrier State Director.

(c) A State must conduct an annual review of its laws and regulations for compatibility and report the results of that review in the annual CVSP in accordance with § 350.213(l) along with a certification of compliance, no later than August 1 of each year. The report must include the following two items:

(1) A copy of the State law, regulation, or policy relating to CMV safety that was adopted since the State's last report.

(2) A certification, executed by the State's Governor, Attorney General, or other State official specifically designated by the Governor, stating that the annual review was performed and that State CMV safety laws remain compatible with the FMCSRs and HMRs. If State CMV laws are no longer compatible, the certifying official shall explain.

(d) As soon as practical after the effective date of any newly enacted regulation or amendment to the FMCSRs or HMRs, but no later than three years after that date, the State must amend its laws or regulations to make them compatible with the FMCSRs and/or HMRs, as amended.
