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.

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 proposa to align the text with the provisions for anti-lock braking systems (ABS) used in other regulations (document GRRF/2015/41).

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.
