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

65. The expert from IMMA introduced GRVA-04-05 and GRVA-04-06, analysing discrepancies between UN GTR No. 3 and UN Regulation No. 78. GRVA invited the expert from IMMA to submit an amendment proposal to UN Regulation No. 78 for review at the next session.

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.

62. The expert from Italy introduced ECE/TRANS/WP.29/GRVA/2019/23, proposing amendments to UN GTR No. 3 as per the mandate adopted by A.C.3 (ECE/TRANS/WP29/AC.3/47). He also introduced GRVA-04-23 including amendments addressing comments received on the proposal. GRVA adopted the proposal as amended with the below correction and requested the secretariat to submit it to the Executive Committee AC.3 for consideration at vote at its March 2020 session.

In ECE/TRANS/WP.29/GRVA/2019/23, para 10, for 5.1.17, read 3.1.17.

63. The expert from Italy also introduced GRVA-04-24, containing the technical report associated to the proposal. GRVA adopted it and requested the secretariat to submit it to the Executive Committee AC.3 for consideration at vote at its March 2020 session.

64. The expert from IMMA stated his satisfaction concerning the adoption of the amendment proposal to UN GTR No. 3. He mentioned that the outcome of this work was not fully harmonized, especially concerning Electromagnetic Compatibility and defeat device requirements.

Proposal to harmonise the requirements of UN R78 with the latest amendments to UN GTR No. 3 adopted by GRVA at its fourth session. Paragraph 5.1.18 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.

74. The expert from IMMA introduced ECE/TRANS/WP.29/GRVA/2020/15, proposing to align UN Regulation No. 78 (Motorcycle braking) with the last amendment to UN GTR No. 3 adopted by GRVA at its September 2019 session.

75. GRVA adopted the proposal and requested the secretariat to submit it (without square brackets) to WP.29 and AC.1 as draft 05 series of amendments to UN Regulation No. 78 for consideration and vote at their June 2020 sessions.
