Proposal to align the REESS definition in the new UN Regulation of fuel system integrity and electric power train safety in the event of a rear-end collision with the definition adopted under UN R100.

Proposal for a new UN Regulation for the type approval of M1 vehicles with a total permissible mass not exceeding 3,500 kg and of N1 with regard to fuel integrity and safety of high voltage systems in case of a rear-end collision. This proposal aligns rear impact (UN R34) and electric vehicle safety (UN R100) requirements with the new EU General Safety Regulation and with GTR 20 on electric vehicle safety.
