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.
10. The expert from Germany introduced a proposal on the activation of a hazard warning signal in case of excess temperature in certain compartments of M2 and M3 buses (ECE/TRANS/WP.29/GRE/2014/39). The expert from OICA introduced an alternative proposal (GRE-72-17). GRE adopted the text as contained in Annex V to the report and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2015 sessions as draft Supplements to the 04, 05 and 06 series of amendments to Regulation No. 48.
