Proposal submitted by the GRRF to clarify provisions concerning the use of Combined Braking Systems (CBS) and for a series of amendments to clarify a variety of requirements, notably concerning test surface requirements, ABS cycling, and peak braking coefficient measurements. The proposal clarifies the terms “inoperative” and “disconnected”, introduces the “K-method”.

Final report on the development of Amendment 2 to the GTR on motorcycle braking submitted for consideration and approval by the World Forum.

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

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.

Voting form for consideration of amendment 2 to GTR 3 on motorcycle brakes and amendment 3 to GTR 4 on heavy-duty vehicle emissions test procedures.

Proposal to align the text 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.

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).

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

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).

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.
