The Working Party on General Safety (GRSG) has approved a proposal to require the automatic activation of hazard warning lights in buses and coaches in the event of excess temperatures in the engine and/or other compartments. This proposal would align UN R48 with this new requirement so a complete set of amendments can be presented for adoption at the March 2015 session of the World Forum.
