21. The expert from EC introduced GRRF-79-18, proposing to clarify the possibility to install means to temporarily reduce or disable the ABS function of motorcycles in certain conditions. The proposal received some comments and the expert from EC volunteered to prepare a revised proposal for the September 2015 session of GRRF.

23. GRRF reviewed ECE/TRANS/WP.29/GRRF/2015/41 and GRRF-80-24 under agenda item 5(b) below.

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.

21. GRRF agreed with the proposal of the expert from EC to reintroduce ECE/TRANS/WP.29/GRRF/2015/41 under agenda item 5(a) and to reconsider the proposal clarifying the possibility to install means to disable the ABS function in certain conditions for L-category vehicles. The expert recalled that a majority of experts expressed specific concerns related to the condition (f) in the proposal at the previous session and therefore agreed to delete it, as shown in GRRF-81-28. The proposal, received some comments to amend the text in a more stringent manner. The expert from IMMA advocated for transitional provisions aligned with those of Euro 5 in Europe. He added that the newly proposed wording was too restrictive and may exclude some vehicles that were already equipped with the feature. GRRF agreed therefore on longer transitional provisions for existing vehicle types, and also to not excessively restrict the kind of vehicle that could be equipped with the ABS off switch function, by softening the wording of these provisions. The Contracting Parties agreed on the amended proposal GRRF-81-28-Rev.1. The expert from Italy expressed a scrutiny reservation on the provisions related to the off road switch. GRRF adopted the proposal as reproduced in Annex III and requested the Secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as a new 04 series of amendments to Regulation No. 78, subject to final review by GRRF in September 2016.
