Proposal as approved by the GRRF to introduce amendments on requirements for movable couplings, increased range of application of remote controls to couplings similar to C50-X and G50-X, possible increase of characteristic values of standard couplings and to include of further requirements on the mounting of couplings.

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 ensure that coupling balls do not block rear lighting and/or registration plates.

Proposal for:

1. An amendment for the separation of the procedures to verify towable mass from the procedure of setting and certifying performance values;
2. An amendment that adds procedures to verify towable mass for vehicle combinations that have hitherto not been accounted for in the Regulation;
3. Amendments that adds integrated fixing points for secondary couplings;
4. An amendment that clarifies the procedure to identify worst cases for certification testing;
5. Amendments that removes typos in the current Regulation.

Proposal to improve the communication document. The current wording of item 2 in Annex 1 is redundant with item 3 and not aligned with similar texts (UN R58 or R73). The key point of item 2 is to identify the type of device or component approved.

Proposal to clarify that flexible components providing part of an articulation are not considered to be a special joint.

Proposal from GRSG to correct the omission of a Corrigendum to remove a subparagraph under paragraph 12.1 in UN R55.

Proposal to correct cross-references. The paragraph 3.3. of Annex 6 is “Drawbar couplings and draw beams” and the paragraph 3.6 is “Drawbars”. Subparagraphs 3.6.1.–3.6.3. prescribe the tests of the drawbars.
