Proposal as prepared by the UN R55 informal group and approved by the GRRF to update UN R55 with respect to:
a) Requirements on remote indication;
b) Availability of information on coupling fixing points for A50X couplings;
c) On lateral strength of drawbars; and
d) a new class definition for fully automatic drawbar couplings.

Proposal to clarify that fully integrated surveillance mirrors may be mounted below 2 metres in cases where they are integrated in a housing including one or more Class II or III mirrors.

Proposal to correct an oversight by aligning the “alternative procedures” provisions of the regulation with the previously adopted amendment of the regulation that raised the rear-impact speed to between 48 and 52 km/h (03 series of amendments).

This proposal clarifies that the provisions concern any cable used in the entire vehicle, not only to those in the interior compartment, engine compartment and separate heater compartment. The proposal also clarifies that the regulation applies not only to electric cables, but also to cable sleeves or cable conduits and it updates the reference to paragraph 5.22. of ISO 6722-1:2011. Specifically, the proposal would apply testing to electric cables, cable sleeves, and cable conduits that exceed a length of 100 mm.

Proposal to modify UN R125 in line with the amendment to UN R46 (indirect vision) that introduces the use of camera-monitor systems (CMS) in place of rear-view mirrors. This proposal also ends the temporary exemption permitting CMS device obstruction of driver field of view from 1 September 2021.

Proposal to

• extend requirements for exterior rear-view mirrors to camera monitor systems;
• reduce the speed threshold for deactivation of emergency controls from 5 km/h to 3 km/h;
• clarify the requirements concerning the height of steps in vehicles which comply with Annex 8;
• limit the mandatory application of the requirements for dedicated areas for prams and pushchairs to Class I vehicles;
• require activation of the alarm and fire suppression systems as soon as the heater is in function regardless of whether the engine is operating;
• extend requirements for exposed seats adjacent to step wells to apply to other exposed seats where there is a risk of the occupant being thrown forward; and
• correct the text of the Regulation.
