Proposal to delete category L₄ vehicles from the scope of the regulation. Motorcycles with a side car (L4 category vehicles) should be tested in a state that is designed to be operated on the road (i.e. the side car fitted to the vehicle) using the test procedures of UN Regulation No. 9. Since UN Regulation No. 41.04 does not cover motorcycles with a side car, this text should be deleted in order to avoid any potential misunderstandings.

6. The expert from IMMA proposed to delete the last sentence in paragraph 1.3.2.1., since the scope of the 04 series of amendments to Regulation No. 41 does not cover motorcycles with a sidecar (L4 category of vehicles) (GRB-65-18). The expert from EC requested more time to study if the proposed modification would also require a change in the European Union (EU) legislation. GRB agreed to continue consideration of this issue at the next session, based on an official document to be submitted by IMMA.

Proposal to delete a description of the L₄ vehicle category (motorcycles with a side car) from Annex 3 to Regulation No. 41. These vehicles fall under the scope of UN R9, having been removed from the scope of UN R41 as of the 04 series of amendments.

4. The expert from IMMA proposed to delete the last sentence in paragraph 1.3.2.1., since the scope of the 04 series of amendments to Regulation No. 41 did not cover motorcycles with a sidecar (L4 category of vehicles) (ECE/TRANS/WP.29/GRB/2017/4). GRB adopted this proposal and requested the secretariat to submit it to the World Forum for Harmonization of Vehicle Regulations (WP.29) and to the Administrative Committee (AC.1) for consideration and vote at their March 2018 sessions as a draft Supplement 6 to the 04 series of amendments to Regulation No. 41.

Regulation No. 53 currently allows for the activation of the stop lamp by application of the brakes only. As already presented at a session of the Working Party on Lighting and Light-Signalling (GRE) (see ECE/TRANS/WP29/GRE/2015/42), IMMA is proposing to introduce the activation of stop lamps under more conditions than the application of the service brake only, e.g. also by regenerative braking. As noted in the report of seventy-fourth session of GRE, see ECE/TRANS/WP29/GRE/74, para. 30: “the proposal might need to be accompanied by a modification of Regulation No. 78 under GRRF.” Therefore, IMMA has prepared this proposal for Regulation No. 78. A revised corresponding proposal on Regulation No. 53 will also be submitted to the October 2017 session of GRE.

21. The expert from IMMA introduced ECE/TRANS/WP.29/GRRF/2017/14 as amended GRRF-84-13 with provisions allowing additional conditions for the activation of the stop lamp. The expert from Canada recommended addressing this question within GTR No. 3. The Chair noted that ETRTO would not be allowed to propose amendments to GTR No. 3 and asked whether a Contracting Party to the 1998 Agreement could sponsor this amendment. GRRF raised the question why the author of the proposal selected provisions from Regulation No. 13 and not from Regulation No. 13-H. The expert from IMMA agreed to submit a revised proposal for the February 2018 session of GRRF.

Proposal to explicitly allow direction indicators to be activated when the motorcycle engine is stopped in order to signal the vehicle status. Some motorcycles currently offer this feature; however, it is not clear whether the scope of Regulation No. 53 covers and allows this function.

31. Due to lack of time, GRE did not consider ECE/TRANS/WP.29/GRE/2017/26, ECE/TRANS/WP.29/GRE/2017/27, GRE-77-08, GRE-77-09, GRE-77-17, GRE-78-22 and GRE-78-24.

Proposal to remove the prohibition against lamps “reciprocally incorporated” with any other lamp. This proposal would align UN R53 with UN R48 and correct an oversight from a previous amendment process.

31. Due to lack of time, GRE did not consider ECE/TRANS/WP.29/GRE/2017/26, ECE/TRANS/WP.29/GRE/2017/27, GRE-77-08, GRE-77-09, GRE-77-17, GRE-78-22 and GRE-78-24.

38. The expert from IMMA proposed to align the text of Regulation No. 53 with Regulation No. 48 and to correct a mistake in the past amendment process (ECE/TRANS/WP.29/GRE/2017/26). GRE adopted the proposal and mandated the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their November 2018 sessions as a draft Supplement 20 to the 01 series of amendments to Regulation No. 53 and as a draft Supplement 2 to the 02 series of amendments to Regulation No. 53.

Proposal to update the definition of “stop lamp” (in line with similar definitions in UN R7 and UN R48) so that it would allow the use of different stop lamp activation methods for powered two-wheelers (e.g. by the application of a retarder or a similar device). A corresponding proposal for amendments to Regulation No. 78 (GRRF/2017/14) has been submitted to the September 2017 session of the Working Party on Braking and Running Gear.

30. The expert from IMMA proposed to allow the use of different activation methods for stop lamps, and to align the stop lamp provisions with those applicable for four-wheelers (ECE/TRANS/WP.29/GRE/2017/25 and GRE-78-07). GRE noted that a corresponding proposal for amendments to Regulation No. 78 had been submitted to the Working Party on Braking and Running Gear (GRRF). The experts from Finland, Germany, Italy, Netherlands and UK commented on the proposal. The Chair invited the expert of IMMA to update the proposal based on the comments received. GRE decided to consider an updated proposal at the next session that would include the issue of its legal form (supplement or a new series of amendments).

IMMA positions expressed for the 15 September 2017 teleconference session.

Proposal of amendments to clarify the original text as proposed in GRRF/2017/14.

Proposal to align the draft Supplement 20 to the 01 series of amendments and draft Supplement 2 to the 02 series of amendments to UN R53 more closely with UN R48. These supplements concern the use of different stop lamp activation methods (in alignment with similar provisions for four-wheeled vehicles).

30.
