24. The expert from Italy consulted GRRF (GRRF-82-04) on a proposal to develop an amendment to GTR No. 3 on motorcycle braking. He informed that Italy, at the forty-eighth session of AC.3, would propose to sponsor this amendment, harmonizing the provisions of the GTR and those in Regulation No. 78, dealing with Electromagnetic Compatibility (EMC), tri-cycles Anti-lock Braking Systems (ABS), Emergency Stop Signal and means to disable the ABS function (‘ABS switch’). The expert from Canada pointed out potential challenges related to the absence of specific EMC testing requirements for braking systems and the obligation to justify why mandating the fitment of ABS on tri-cycles. GRRF supported the content of GRRF-82-04. The expert from Italy volunteered to request the authorization to develop Amend. 3 to GTR No. 3 at the forty-eighth session of AC. 3 in November 2016.
