33. The expert from Germany introduced ECE/TRANS/WP.29/GRSG/2013/27 proposing more stringent requirements for rear underrun protection devices. He also presented GRSG-105-23 with a detailed cost-benefit analysis carried out in Germany on this subject. The expert from IRU raised concerns by his organizations and presented a number of observations (GRSG-105-06). The expert from OICA proposed an alternative text for amending UN Regulation No. 58 (GRSG-105-20). The expert from CLCCR presented some observations and recommendations of her organization (GRSG-105-26).

34. GRSG welcomed the proposal by Germany including the cost-benefit analysis, but noted a number of comments and reservations. Following the discussion, the Chair suggested keeping the subject on the agenda of GRSG instead of establishing a new informal group and invited all experts to transmit their written comments to the expert from Germany. GRSG agreed to resume consideration at its next session in May 2014, on the basis of a revised proposal to be submitted by Germany taking into account the comments received. The secretariat was invited to distribute GRSG-105-20 with an official symbol.
