Request for authorization to develop amendments to GTR No. 3 in order to:

1. align GTR 3 with Supplement 3 to the 03 series of amendments to UN Regulation No. 78 adopted at June 169/WP.29 (electromagnetic compatibility requirements for ABS, application of ABS provisions to three-wheelers, installation of emergency stop signal) and
2. clarify the possibility to install a means to disable the ABS function (‘ABS Switch’) under certain conditions.

Proposal to develop an amendment in order to align GTR No. 3 with technical progress, addressing among others: ensuring electromagnetic immunity of ABS-systems, introducing ABS performance requirements for category 3-5 vehicles (three-wheelers), ensuring uniform requirements for equipment such as Electronic Stop Signal System and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78.
