Revised proposal, pursuant to the discussions at the 109th GRSG session, to modify UN R125 in line with the proposed amendment to UN R46 (indirect vision) that introduces the use of camera-monitor systems (CMS) in place of rear-view mirrors (i.e., document GRSG/2015/2). This proposal is part of a package of proposals to amend the UN Regulations impacted by the amendment to UN R46 and would extend the provisions for rear-view mirrors to CMS devices.
45. The expert from Germany presented GRSG-109-23-Rev.1 (superseding document ECE/TRANS/WP.29/GRSG/2015/8) introducing new requirements for the indirect view of the driver in case vehicles were equipped with camera-monitor systems. GRSG adopted ECE/TRANS/WP.29/GRSG/2015/8 as reproduced in Annex VII and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2016 sessions, as draft Supplement 1 to the 01 series of amendments to UN Regulation No. 125.
46. In this respect, GRSG intended to promote the introduction of camera-monitor systems (CMS) in vehicles of category M1 also by allowing for a temporary period an obstruction in the direct field of view of the driver by the installation of a monitor in place of a mirror. GRSG agreed to remove this temporary exemption such that the Contracting Parties shall not be obliged to accept, as from 1 September 2021, approvals based on the new paragraph 22.214.171.124. of UN Regulation No. 125.
