This legislation directs the Secretary of Transportation to revise specific requirements related to state highway safety plan submissions. The goal is to streamline the process for states participating in highway safety programs under section 402 of title 23, United States Code. Within 180 days of the bill's enactment, the Secretary must implement changes allowing a triennial management review conducted by the National Highway Traffic Safety Administration (NHTSA) to fulfill certain documentation obligations. This means that the NHTSA review can satisfy the information and documentation requirements for a state's triennial highway safety plan submission for the period covered by that review, reducing redundant administrative burdens.
