Proposed additions to the Statement of technical rationale and justification in GTR 16 (tyres), especially to clarify application and future development of the regulation.

CLEPA remarks defining sensor mounting requirements for heavy vehicles (Horizontally: up to 600 mm out of vehicle center; Vertically: between 330 mm and 800 mm above road-surface level) in order to avoid safety risks.

EC responses to IMMA comments (document GRRF-80-13) on the proposa to align the text with the provisions for anti-lock braking systems (ABS) used in other regulations (document GRRF/2015/41).

EC responses to IMMA comments (document GRRF-80-13) on the proposal to align the text with the provisions for anti-lock braking systems (ABS) used in other regulations (document GRRF/2015/40).

Proposal to remove provisions related to temporary/spare units, TPMS and to exceptional cases that would require type approval under UN R75 or R106.

Proposal to ensure that coupling balls do not block rear lighting and/or registration plates. In line with the EU General Safety Rule, Annex IV specification for application of UN R55, couplings that might block lighting or plates must be removable, repositionable, and unlockable in order to make it easier for users to remove them or reposition them when not in use (e.g., towing a trailer.) Coupling balls that are so designed as to be unable to block lighting or plates may still incorporate locks and/or require tools to remove or reposition.

OICA proposal, as revised pursuant to comments received during the 80th GRRF (September 2015) session, to amend the Introduction section of UN R131 to highlight technical issues related to the installation of AEBS on some specific vehicles included in the scope of the regulation.

Under the International Whole Vehicle Type Approval (IWVTA) program, brake assist systems (BAS) and electronic stability controls (ESC) would be separated from UN R 13-H into new stand-alone regulations. This document has been prepared by an ad hoc group in order to ensure adequate transitional provisions to enable Contracting Parties to adapt to the new approach.

IMMA presentation regarding the intention to propose emergency stop signal (ESS) provisions to UN R78 and GTR No. 3. ESS, which automatically activates hazard warning lights during forceful braking situations, already exists under UN R13-H for cars and trucks. IMMA has submitted document GRE-2015-40 to similarly amend UN R53.

Proposal for a separate TPMS regulation, removing the Tyre Pressure Monitoring System provisions out of UN R64, in order to facilitate the establishment of the International Whole Vehicle Type Approval system. It is based on document GRRF/2015/13 taking into account the comments received at GRRF-78.

Draft proposal for a revised UN R64, removing the type-pressure monitoring systems provisions, in order to facilitate its use in the International Whole Vehicle System.

This document supersedes the official document GRRF/2014/13. It includes all the proposals introduced per document GRRF-79-08 and some of the proposal introduced per document GRRF-80-26.

Revised proposal by Italy pursuant to comments received during the 80th GRRF (September 2015) session to introduce provisions for the approval of replacement brake discs for L-category (motorcycle and related) vehicles.

Progress report on the development of provisions for automatically commanded steering functions under UN Regulation No. 79.

Proposal for a new annex concerning “special additional requirements for trailers of category O₂ without pneumatic connections and equipped with service braking systems with pneumatic energy storage devices”.

Proposal to introduce a new Annex 7: “Special provisions for the powering of trailer steering systems from the towing vehicle” and otherwise amend the regulation to enable the approval of such trailer steering systems which the current text prohibits.

Text as approved by the GRRF and prepared by the UN R55 informal group to update this regulation 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.
