5. GRE took note of statements by the experts of Japan, United Kingdom of Great Britain and Northern Ireland, United States of America and the European Commission related to their positions on the aggression of the Russian Federation against Ukraine (annex II of the session report). The experts of Australia, France, Germany, Italy and Poland supported these statements.

6. No information was reported under this item.

7. The expert from the WP.29 Informal Working Group on Periodical Technical Inspections (IWG PTI) presented a concept on the whole life compliance of vehicles (GRE-86-04). GRE supported the proposed concept and agreed to follow-up on the project.

8. GRE noted the progress of the Informal Working Group “Simplification of the Lighting and Light-Signalling Regulations” (IWG SLR) (GRE-86-07). The expert of IWG SLR proposed amendments to the work plan and time schedule as contained in the Terms of Reference (GRE-86-06). GRE adopted these modifications, as contained in Annex III of the session report, and extended the IWG SLR mandate until December 2025.

9. GRE recalled that, at its previous session, it had requested IWG SLR to consider an alternative transitional provision for the preceding series of amendments to allow for the phasing out of outdated lamps/devices (GRE-85-30). GRE noted that IWG SLR had agreed to specify in paragraph 6 “Individual specifications” of UN Regulation No. 48 (starting from the 09 series of amendments) which series of amendments of lamps/devices are required to be installed on vehicles for new type approvals, to enable phasing out of the installation of devices approved according to the previous series of amendments. While generally supporting this approach, GRE requested IWG SLR to take measures that would avoid a proliferation of new series of amendments to UN Regulation No. 48.

GRE-85-30 | UN R148: Proposal to amend the transitional provisions of proposal for new series of amendments Proposal to amend the transitional provisions of GRE/2021/13 (R148) , GRE/2021/14 (R149) and GRE /2021/15 (R150)

10. On behalf of the Informal Working Group on the electronic database for the exchange of type approval documentation (IWG DETA), the expert from France introduced their views on the use of the Unique Identifier (UI) (GRE-86-17). GRE reiterated its support to use UI as an alternative to traditional approval markings. GRE agreed that, for the sake of efficient application of UI in the context of simplified UN Regulations Nos. 148, 149 and 150, a summary document should be made available in DETA and that a template for the summary document should as soon as possible be introduced into these UN Regulations by means of a Supplement. GRE noted that IWG SLR volunteered to draft the summary document without delay, with the aim to have a proposal for the next session of GRE.

11. The expert of IWG SLR mentioned clarifications and corrections to the draft 01 series of amendments to UN Regulation No. 148 (GRE-86-03). GRE noted that they had already been included in ECE/TRANS/WP.29/2022/92 that will be considered by WP.29 in June 2022.

GRE-86-03 | UN R148: Corrections to the draft proposal for a 01 series of amendments This document was produced for transparency purposes to show the corrections of some purely editorial errors, which were identified during the preparation of the WP.29 proposal to introduce the 01 series of amendments to Regulation No. 148. Such corrections were reflected by the Secretariat in the WP.29 proposal.

12. The expert of IWG SLR introduced clarifications and corrections for the 00 series of amendments to UN Regulation No. 149 (ECE/TRANS/WP.29/GRE/2022/8). GRE adopted the document and requested the secretariat to submit it for consideration and vote at the November 2022 sessions of WP.29 and AC.1 as draft Supplement 5 to the original series of amendments to UN Regulation No. 149.

GRE/2022/8 | UN R149: Proposal for Supplement [5] to 00 series of amendments Proposal to amend text resulting that may be misinterpreted as if now only systems that include “means of an appropriate adjustment” need to be marked with the double-headed arrow, and symmetrical devices are no longer required to be marked.

13. The expert of IWG SLR also presented clarifications and corrections to the text of the draft 01 series of amendments to UN Regulation No. 149 (ECE/TRANS/WP.29/GRE/2022/4). GRE adopted the document and requested the secretariat to submit it for consideration and vote at the June 2022 sessions of WP.29 and AC.1 as an informal document to correct the draft 01 series of amendments to UN Regulation No. 149 (ECE/TRANS/WP.29/2022/93). GRE recalled a question raised by the expert from Germany concerning footnote (a) to paragraph 5.2.2. in the draft 01 series of amendments to UN Regulation No. 149 (ECE/TRANS/WP.29/GRE/85, paragraph 14) and noted that it had been clarified by IWG SLR.

GRE/2022/4 | UN R149: Proposal to clarify and to correct the text of the draft 01 series of amendments Proposal by the Informal Working Group on Simplification of Lighting and Light-Signalling Regulations (IWG SLR) with the aim to clarify and to correct the text that may be misinterpreted as if now only systems that include “means of an appropriate adjustment” need to be marked with the double-headed arrow, and symmetrical devices are no longer required to be marked.

WP.29/2022/93 | UN R149: Proposal for the 01 series of amendments Proposal aim to allow driver assistance projections on the road ahead of the vehicle as part of the Adaptive Driving Beam (ADB), to allow the installation of Adaptive Driving Beams (ADB) on vehicles of category L₃, and otherwise to comprehensively clarify and update the text.

14. No documents were considered under this agenda item.

15. The expert of IWG SLR reported on their work on a new series of amendments to UN Regulation No. 48 that introduces new requirements for headlamp levelling (GRE-86-07). GRE noted that IWG SLR was collecting anonymous vehicle levelling data for type approval and for conformity of production, with the aim to prepare an informal proposal for the GRE session in October 2022 and a formal document for the GRE session in April 2023. The expert from IWG SLR also invited those experts, who were not in a position to support the aiming diagram in ECE/TRANS/GRE/2020/8/Rev.2, to submit concrete alternative proposals for consideration.

GRE-86-07 | Progress report of the SLR informal group

GRE/2020/8/Rev.2 | UN R48: Revised proposal for a new series of amendments Proposal from the SLR informal group to introduce new requirements for headlamp levelling, in particular on the vertical inclination in relation to the dipped-beam headlamp mounting height, and to allow manual levelling only for off-road vehicles.

16. GRE noted that new proposals were expected to be submitted to the next session.

17. The expert from GTB proposed to remove the minimum distance between the left and right front/rear position lamps (ECE/TRANS/WP.29/GRE/2022/2). The experts of Germany, Netherlands and the United Kingdom of Great Britain and Northern Ireland raised some issues. GRE invited GTB to discuss with these experts their concerns and decided to revert to the issue at the next session.

GRE/2022/2 | UN R48: Proposal for a Supplement to the 06, 07 and 08 series of amendments Proposal to remove the minimum distance between the left and right front/rear position lamps.

18. The expert from CLCCR proposed to allow the installation of manoeuvring lamps on trailers (ECE/TRANS/WP.29/GRE/2022/5). Following an in-depth discussion, GRE adopted the proposal, as amended by GRE-86-05-Rev.2 and requested the secretariat to submit it for consideration and vote at the November 2022 sessions of WP.29 and AC.1 as draft Supplement 17 to the 06 series, draft Supplement 4 to the 07 series and draft Supplement 2 to the 08 series of amendments to UN Regulation No. 48. GRE also noted that CLCCR would submit to the next session, further proposals on this topic (GRE-86-05-Rev.3) as a draft new series to UN Regulation No. 48. GRE invited all experts to send to CLCCR their comments, if any, by the end of May 2022.

19. GRE took note of GRE-86-16 submitted by the expert of OICA on using direction indicators to warn about unattended children left in cars. GRE was informed about the plans of the European New Car Assessment Programme (Euro NCAP) to include detection of such children into its assessment programme as of 2025. GRE noted that this issue was under consideration by the Working Party on Passive Safety (GRSP) and that the Working Party on Noise and Tyres (GRBP) was starting a discussion on using the vehicle horn (UN Regulation No. 28) for the same purpose. GRE agreed that the frequency and pattern of the flashing of direction indicators need to be defined and invited all experts to send their ideas to OICA, with the aim to prepare a revised proposal for the next session. Given the involvement of various Working Parties, GRE held the view that coordination at the WP.29 and/or AC.2 would be necessary and requested the Chair to raise this topic at the June 2022 meetings of these bodies. GRE also pointed out that, until a coordinated and harmonized approach had been developed, it would be premature to include the relevant requirement into the car assessment programme. GRE invited its experts to convey this message to Euro NCAP.

GRE-86-16 | UN R48: Proposal for a new Supplement to the 06, 07 and 08 series of Amendments Proposal to introduce the use of all of the direction-indicator lamps in case the presence of an unattended child is detected inside the passenger compartment.

20. GRE noted the progress of the Special Interest Group (SIG) on park conditions and an answer-back signal (GRE-86-10) as well as an approach proposed by the expert from Japan (GRE-86-11). GRE agreed that the requirements for lamps on vehicles in the parked condition would be introduced in two steps:

• Regulating current lighting functions under the parked condition by means of a new 09 series of amendments to UN Regulation No. 48. To avoid a proliferation of new series, GRE agreed that this new series should also include other amendment proposals that were in discussion, such as device transition provisions and headlamp levelling.
• Including the optional use of new lighting functions in the parked condition, by means of a Supplement to the 09 series.

22. The expert from Germany tabled a proposal for a new 04 series of amendments to UN Regulation No. 53 that aimed to improve road safety by deleting headlamps of Classes A and BS from this UN Regulation (ECE/TRANS/WP.29/GRE/2022/3). The expert from Czechia proposed modifications (GRE-86-15). Several experts made preliminary comments and pointed out that they would need more time to study the proposal. GRE invited all experts to send their comments to the authors, in order to prepare a revised document for consideration at the next session.

25. GRE was informed that the Global Forum for Road Traffic Safety (WP.1), at its recent session in March 2022, had completed its review of the amendments to the Vienna Convention and requested that the secretariat create a final, formal document for a possible adoption at the next session. The Government of Italy declared that it intended to formally submit this amendment proposal to the Depository, the Secretary-General of the United Nations, for dissemination to all contracting parties.

26. GRE also noted that the International Federation of Pedestrians (IFP) had submitted to WP.1 an informal document outlining its position on the safety requirements for automated vehicles (AVs) to indicate their status and to communicate their intended actions. IFP opposed the introduction of signals (optical or audible) indicating AVs intended actions to pedestrians. At the same time, IFP was not opposed to signals indicating the status of the vehicle (whether the autonomous mode is on or not) as long as pedestrians were not expected to change their behaviour in the presence of this signal.

28. The experts of the Task Force on Autonomous Vehicle Signalling Requirements (TF AVSR) briefed GRE on the WP.29 and AC.2 discussions on coordination of work on Automated Driving Systems (ADS), including the conditions, if any, under which an ADS external lighting signal should be activated (GRE-86-13). Pending recommendations of the Working Party on Automated/Autonomous and Connected Vehicles (GRVA) and AC.2 guidance on the issue, the experts of TF AVSR proposed reviewing UN Regulation No. 48 in the context of ADS with the aim to develop alternative switching of light signalling functions independent of the driver (GRE-86-12). GRE stressed the need to screen UN Regulation No. 48 to identify which amendments would be necessary to cater for ADS level 3 and below. GRE noted that TF AVSR would convene a kick-off meeting on this topic in June 2022 and encouraged all experts to participate.
