National Highway Traffic Safety Administration December 20, 2024 – Federal Register Recent Federal Regulation Documents

Consistent with a Global Technical Regulation on electric vehicle safety, NHTSA is establishing Federal Motor Vehicle Safety Standard (FMVSS) No. 305a to replace FMVSS No. 305, "Electric-powered vehicles: Electrolyte spillage and electrical shock protection." Among other improvements, FMVSS No. 305a applies to light and heavy vehicles and includes performance requirements for the propulsion battery. NHTSA is also establishing a new regulation, part 561, "Documentation for Electric-powered Vehicles," that requires manufacturers to compile risk mitigation documentation and to submit standardized emergency response information to assist first and second responders handling electric vehicles.
