Proposal by the Informal Group on Camera-Monitor Systems (IGCMS-II) to introduce the optional replacement of mirrors of Classes I to IV by camera-monitor systems.

Proposal 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.

Proposal to align UN Regulation No. 10 with the proposed amendments to Regulation No. 46 (document GRSG/2015/2) to enable the replacement rear-view mirrors by camera-monitor systems. This proposal is also subject to the consent of the Working Party on Lighting and Light-Signalling (GRE).

Proposal to treat camera-monitor systems the same as rear-view mirrors under UN R26 in view of the amendment to UN R46 to enable the replacement of rear-view mirrors by CMS (i.e., document GRSG/2015/2).

Proposal to ensure that all devices for indirect vision, including exterior cameras, are covered by UN R61. This proposal is part of a package of proposals to update various regulations impacted by the proposed amendment to enable the replacement of rear-view mirrors by camera-monitor systems.

Proposal to adapt UN R79 in line with the proposed addition of camera-monitor systems to UN R46 (indirect vision). UN R79 refers to external mirrors in test procedures involving the vehicle turning circle. This proposal replaces the reference to mirrors with a broader reference to “indirect vision devices” that includes CMS.

Proposal to align UN R94 with the draft amendment to add camera-monitor systems to UN R46 (i.e., document GRSG/2015/2). Under UN R94, the measurement for the 40% overlap between the vehicle and crash barrier excludes external rear-view mirrors. This proposal would extend the same treatment where the mirror has been replaced by an exterior camera.

UN R107 includes a provision to prevent a folding seat used by the crew from obstructing the view of the exterior rear-view mirror. In light of the proposed amendment to introduce camera-monitor systems into UN R46 (indirect vision), this proposal would extend the same treatment to CMS used in the place of rear view mirrors.
