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.

Technical report to accompany the proposal for amendment 3 (concerning mainly ABS issues) to GTR 3.

Proposal to

1. delete paragraph 3.1.15.3 as it is an unnecessary provision under self-certification systems and addresses deceleration measurement criteria referenced elsewhere in the regulation
2. clarify that the ABS tell-tale must be yellow
3. delete the prohibition on defeat devices due to the absence of objective and repeatable procedures for assess conformity necessary under self-certification.
