This proposal aims to improve brake distribution between truck and trailer of heavy vehicle combinations at everyday low decelerations, to enhance uniform use of all wheel brakes and thereby to counteract loss of full brake performance. The proposal is based on ISO 20918.

UN R107 requires the installation of driver seat with suspension systems. This IRU proposal, based on the earlier informal proposal GRSG-99-22, would exempt Class I urban buses from this requirement in UN R107.

This proposal aims to improve brake distribution between truck and trailer of heavy vehicle combinations at everyday low decelerations, to enhance uniform use of all wheel brakes and thereby to counteract loss of full brake performance. The proposal is based on ISO 20918 and supercedes GRRF-72-07.

IRU argument against the introduction of a mandatory provision in UN Regulation No. 107 to provide a dedicated space for prams in Class I buses.

IRU request for a risk assessment on CNG and LNG vehicles pursuant to a coach fire during which the main valves on CNG cylinders ruptured.

IRU observations and conclusions regarding the German proposal (document GRSG/2013/27) to introduce more stringent requirements for rear under-run protection devices.

Proposal by the International Road Transport Union (IRU) to amend the proposal by Germany that increases the stringency of the UN R58 rear underrun performance requirements. This proposal would delete the labeling provision (para. 16.7) in the German proposal (document GRSG/2015/17).

IRU believes that the revised proposal by Germany (ECE/TRANS/WP.29/GRSG/2016/20 and its Corr.1) to insert new amendments might create an additional burden on road transport operators without increasing road safety. IRU cannot support the German proposal and thinks that it would be more appropriate to address the issue with a cost benefit analysis, where the safety benefit can be justified.
