Abstract
This document delays until March 20, 2025, the effective date of the December 20, 2024, final rule that adopted Federal Motor Vehicle Safety Standard (FMVSS) No. 305a to replace FMVSS No. 305, "Electric- powered vehicles: Electrolyte spillage and electrical shock protection." FMVSS No. 305a applies to light and heavy vehicles and includes performance requirements for the propulsion battery. The final rule also established a part entitled, "Documentation for Electric- powered Vehicles," that requires manufacturers to compile risk mitigation documentation and submit standardized emergency response information to assist first and second responders handling electric vehicles.
