Refinements to the proposal to align the GTR text with updates to UN R78 introduced in response to technological progress in motorcycle braking.

Proposal to align GTR No. 3 with technical progress, addressing among others: electromagnetic compatibility/immunity of ABS-systems, ABS performance requirements for category 3-5 vehicles (three-wheelers), uniform requirements for equipment such Emergency Stop Signal and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78 while addressing its use under self-certification compliance systems.

Proposal to ensure consistency between GTR 3 and UN R78 in light of the proposed amendments to GTR 3 (GRVA/2019/23). Paragraph 5.1.17 aims to clarify with an explicit article that the rider is duly informed when activating a riding mode that disables the ABS on the rear axle.

Side-by-side comparison of GTR 3 and UN R78 provisions.

Proposal for editorial corrections and clarifications concerning activation of a riding mode with ABS disabled. The changes are also being concurrently proposed for UN R78.
