Document GRSG/2015/8 proposes to amend the provisions on forward field of vision of drivers in UN R125 to promote and to support the installation of camera-monitor devices on vehicles of category M1. This proposal would clarify that the amendment only applies to regulated devices for indirect vision.

An accident occurred where an N1 security vehicle fatally injured a child who was crossing the entrance to a supermarket car park. The vehicle had been modified from the original specification of the manufacturer by the removal of the side windows and the fitting of plastic glazing on both sides of the driver’s cab area, and a frame of strengthening material fitted to the replacement glazing. This reduced the side vision for the driver of the vehicle. Since UN R125 applies to M1 vehicles, the UK seeks guidance from GRSG on the application of UN R125 provisions to N1 vehicles.

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.
