Working Party on Brakes and Running Gear | Session 80 | 15-18 Sep 2015
Geneva
Agenda Item 5. (b)
Global Technical Regulation No. 3

24. The expert from EC introduced ECE/TRANS/WP.29/GRRF/2015/40 and ECE/TRANS/WP.29/GRRF/2015/41, proposing to clarify the possibility to install means to temporarily reduce or disable the ABS function of motorcycles in certain conditions. The expert from Canada submitted an alternative wording (GRRF-80-19) and recalled that an authorization from the Executive Committee AC.3 for developing an amendment to GTR No. 3 would be required. The proposal received some general comments related to road safety. The expert from IMMA briefly introduced GRRF-80-13 commenting the proposals to which the expert from EC responded (GRRF-80-24 and GRRF-80-25). A majority of experts expressed a specific concern related to condition (f). The expert from EC volunteered to prepare two revised proposals for the [February 2016] session of GRRF.

25. The expert from EC introduced GRRF-79-17, proposing to apply to tricycles the existing ABS requirements for PTWs. The proposal was accepted in principle as it proposed a harmonization with the corresponding EU directive. As the proposed wording would also affect other Category 3 vehicles, the expert from EC volunteered to prepare a revised proposal for the February 2016 session of GRRF.
