Proposal to allow Emergency Stop Signal (ESS) systems on motorcycles and related vehicles.

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.

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.

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).

Discussion document raising concerns and offering proposals concerning motorcycle ABS testing.

Documents GRRF/2015/40 and 41 propose to align GTR 3 and UN R78 with the provisions for anti-lock braking systems used in other regulations. The proposal clarifies the limits on the use of any temporary ABS deactivation switch and prohibition against permanent disabling of ABS if fitted on a motorcycle. IMMA wishes to make the wording more technology-neutral, clarify test conditions considered impractical, and allow time for manufacturers to comply (i.e., add transitional provisions).

Proposal to clarify the electromagnetic compatibility requirements under UN R78 with regard to the application of UN Regulation No. 10.

Proposal to align the text with the provisions for anti-lock braking systems used in other regulations, including specific exemptions for certain off-road vehicles as incorporated in UN Regulation No. 13. The proposal clarifies the limits on the use of any temporary ABS deactivation switch and prohibition against permanent disabling of ABS if fitted on a motorcycle.

Proposal to include three-wheeled category l vehicles within the scope of ABS testing under UN R78. This would align the scope with EU Directive 93/14/EEC.

Reference prepared by the WP.29 secretariat

Proposal to include three-wheeled category l vehicles within the scope of ABS testing under UN R78. This would align the scope with EU Directive 93/14/EEC.

Presently, it is not fully clear whether an anti-lock braking system (ABS) switch-off or altering mode is permitted on L-category vehicles, whereas it is clearly not allowed on other vehicle categories. This proposal is aimed at ensuring a consistent approach for all motor-vehicles equipped with anti-lock braking systems, including specific exemptions for certain off-road vehicles as incorporated in UN Regulation No. 13.

Information on the mandatory installation of advanced brake systems for motorcycles and of Lane Departure Warning Systems for heavy-duty vehicles.

Proposal to require proof of electromagnetic compatibility through compliance with UN R10 or any other equivalent test as may be agreed between the manufacturer and test service.
