The 1st DETA/IWVTA Joint Workshop is scheduled for June 17, 2026, 9:30–12:30 (CEST) as a hybrid meeting in Flensburg. The provisional agenda includes opening remarks from the DETA Chair, IWVTA Chair, and President of KBA. Part 1 covers DETA topics: what DETA is, a demonstration, ASEAN countries’ expectations, and ways to make DETA more attractive. Part 2 covers IWVTA topics: what IWVTA is, industry’s expectations, issuance and acceptance of IWVTA certificates in the EU, and ways to make IWVTA more attractive. The workshop concludes with any other business.

IWVTA is an internationally recognised whole vehicle type approval scheme within the revised 1958 Agreement framework. It establishes mutual recognition of vehicle type approvals at the whole vehicle level across Contracting Parties, eliminating requirements for further testing, documentation, or certification for safety, environment, energy, and anti-theft. IWVTA comprises two approaches: U-IWVTA applies the highest stringency of latest UN Regulations, while L-IWVTA permits omissions or lower stringency versions. The scope is limited to passenger cars. Merits include simplified type approval systems, reduced testing and administrative costs, and shortened processing times.

OICA proposes amendments to LUPC-09-04: amend para. 2.5.22. to expand the definition of energy status indicator to include information on the operational status of energy transfer and illumination to assist in locating electrical connection; delete existing para. 3.2.10. and its subparagraphs; add new paras. 3.2.10. and 3.2.11. requiring statements on energy status indicator lamps and lamp test mode; and amend para. 6.29.9. to clarify that multiple energy status indicators may be installed, change the flashing frequency limit from 2.0 Hz to 5.0 Hz, and enlarge the maximum apparent surface area to accommodate various plug sizes and surrounding illumination designs.

The document is an agenda for the 31st meeting of the GRE Taskforce on Autonomous Vehicle Signalling Requirements, scheduled for 18 June 2026 from 09:00 to 13:00 CEST via WebEx. The agenda includes welcome remarks, introduction of participants, adoption of the agenda (AVSR-31-01), approval of the report of the 29th meeting (AVSR-30-05), a report from GRE-94 / TF FADS (GRE-94-23), discussion of ADS marker lamps including Japanese input and a draft hybrid regulation proposal (AVSR-28-02, AVSR-30-03, AVSR-31-02/-03), miscellaneous items, working plan for future steps, and next meeting arrangements. Japan has offered to host a September meeting in Tokyo.

Draft technical specifications establish mandatory ADS marker lamps on motor vehicles of categories M₁–M₃, N₁–N₃, L₆, and L₇, with front and rear lamps mandatory and side lamps mandatory or optional depending on vehicle length. Front lamps require daytime photometry of 50–300 cd and nighttime 10–125 cd; rear lamps require 20–120 cd daytime and 4–42 cd nighttime. Side lamps vary by type. All lamps are blue-green turquoise, mounted at minimum 250 mm height, and activate automatically only in fully automated mode with manual switching prohibited.

The European Commission presents prioritized proposals toward updating UN R10 to address transformative vehicle technologies including electrification, automated systems, steer-by-wire, V2X communication, and software-defined vehicles. Current interpretation does not guarantee safety and environmental protection under real road conditions. Proposals include assessing radiated emissions from four vehicle sides rather than two, testing under normal driving conditions, and establishing agreement on drive cycles and transients. These proposals align with WP.29 guidance, improve safety, ensure reproducibility, and represent adaptation to technological progress, based on follow-up of EMC-46-04 and EMC-49-09.

This document presents the draft agenda for the 8th meeting of the GRE Task Force on Glare Prevention, scheduled for 9 June 2026 at CLEPA Headquarters in Brussels. The agenda includes welcome remarks, adoption of the agenda, approval of the previous meeting report, feedback from GRE-94, and status updates on HWT on PTI, ADB/AFS, and Regulation 48. Discussion topics cover horizontal adjustment of passing- and driving-beam and AFS-ADB, vehicle preparation for passing-beam measurement, and updates from the GTB Task Force Glare Control. Future meetings are scheduled for Tokyo in September 2026 and Brussels in December 2026.

OICA opposes introducing a regulatory requirement for horizontal adjustment of passing-beam/driving-beam and for AFS/ADB to the current SLR agenda. The proposal does not contribute to simplification of lighting regulations, no identified safety concern or ambiguity justifies this requirement, and it lacks a formal proposal from a Contracting Party, NGO, or other stakeholder. The SLR group is managing several longstanding unresolved issues, and introducing this topic risks further delaying progress. Harmonized requirements require comprehensive understanding of Periodic Technical Inspection specifications across all Contracting Parties, which are currently unavailable.

Annex 6 specifies methods for measuring variations in motor vehicle passing-beam inclination caused by changes in vehicle attitude due to loading. Para. 4 establishes vehicle preparation requirements: vehicles shall have travelled between 1,000 km and 10,000 km; tyres shall be inflated to full-load pressure with full fuel replenishment; parking brake released and gearbox in neutral; conditioning for at least 8 h at specified temperature; and headlamps with well-defined passing-beam cutoff should preferably be installed. Comments on para. 4 question compatibility with periodic technical inspection (PTI) requirements.

The agenda includes review of Terms of Reference and Rules of Procedure, a recap of the GRE 94th session, discussion of questionnaires, a proposal for modification of UN R48, follow-up on action items, review of existing Regulations and Standards, and announcement of the next meeting.

The session discussions addressed the Energy Status Indicator, including modifications to paragraph 2.5.22. defining illumination to assist socket connection, revisions to paragraph 6.29.9. establishing maximum flashing frequency of 5 Hz, and paragraph 6.29.9.5. setting surface size limits up to 150 cm² around sockets. Colour convention for charging status indicators was debated, with proposals for blue (charging), green (charged), orange (failure), and red (danger), to be discussed at the April GRE session. The Lamp Test Mode section addressed concerns regarding testing scope and removed requirements for AFS testing and driving beam testing.

The Homework Team on ADB/AFS status report to the GRE Taskforce “Glare prevention” documenting timeline activities from February to June 2026, including seven HWT meetings and three TFGP sessions. The team listed system descriptions, benefits, disadvantages, conducted literature review, identified elements causing glare, negative effects to ADB/AFS performance, and improvable requirements. The team drafted recommendations addressing enforcement of headlamp cleaning, reduction of 2000lm limit, manual override requirements, improved detection and camera specifications, motorway ADB usage, cleaning systems, beam pattern dimming, and adaptive beam patterns for various driving conditions.

The document addresses simplification of the definition of “apparent surface” and single lamp distance requirements in UN R48. It presents a new CAD-based concept defining apparent surface using light emitting surface with clear outer lens disregarded. The document notes that current regulation allows multiple ways to define apparent surface resulting in different distances, with existing approvals having distances significantly larger than 75mm between distinct parts without known safety issues. GTB agrees on simplifying the apparent surface definition to describe function contours as seen by road users, while acknowledging this should not restrict possible designs. The document references a 1999 INF Milano study concluding symmetric appearance is relevant for vehicle identification and larger distances are acceptable for symmetric compared to asymmetric constellations.

Proposal to amend, restructure, and clarify UN R86:

• Update the regulation title and scope to reference vehicles of category T, R, S, agricultural and forestry NRMM vehicles regarding installation of lighting and light-signalling devices
• Restructure and reorganize para. 2 (Definitions) by consolidating lamp definitions, deleting outdated definitions, and reorganizing vehicle-related and lamp-related definitions into separate sections
• Revise para. 3 (Application for approval) to clarify submission requirements and add reference to Annex 1 documentation
• Amend para. 4 (Approval) to reference Schedule 4 of the 1958 Agreement and update approval mark procedures in Annex 2
• Restructure para. 5 (General specifications) by reorganizing and renumbering provisions relating to lamp position (para. 5.5.), geometric visibility (para. 5.6.), single lamps (para. 5.9.2.), tell-tale requirements (para. 5.14.), concealable lamps (para. 5.15.), and lamps of variable position (para. 5.17.), and revise provisions regarding electrical connections for front and rear position lamps, driving-beam and passing-beam headlamps, and daytime running lamps
• Restructure and revise para. 6 (Individual specifications) by introducing para. 6.0. as a general introductory provision, renaming driving-beam and passing-beam headlamps throughout, reorganizing direction-indicator lamp arrangements as A, B, C, D, E with detailed geometric visibility specifications in para. 6.5.5., revising stop lamp position and geometric visibility requirements in para. 6.7., restructuring front and rear position lamp requirements, revising rear fog lamp electrical connections, clarifying parking lamp requirements, restructuring rear and front retro-reflector specifications to include separate sections on electrical connections, tell-tale, and other requirements, reorganizing side-marker lamp provisions, clarifying conspicuity marking requirements, revising SMV rear marking plate specifications, restructuring exterior courtesy lamp and manoeuvring lamp requirements, and updating all light colour specifications
• Amend para. 8 (Conformity of production) to include reference to the Agreement Schedule 1 and clarify the conformity requirements
• Clarify para. 10 (Production definitively discontinued) regarding notification requirements
• Revise para. 12 (Transitional provisions) to replace existing series-specific provisions with general transitional provisions applicable to all series of amendments and add new transitional provisions for the 04 series of amendments with dates specified as 1 September 20xx (pending confirmation)
• Update Annex 1 (Communication) to reference the 04 series of amendments in the approval mark examples and add informative tables (TableA4-1 and TableA4-2) in Annex 4 (previously Annex 3) summarizing lighting and light-signalling installation rules for tractors/agricultural and forestry NRMM (vehicles of category T) and vehicles of categories R and S
• Revise Annex 2 (Examples of arrangements of approval marks) to reference the 04 series of amendments and update marking examples
• Delete Annex 3 (The relevant parts of Annex 3 to UN Regulation No. 48 apply) and replace with visibility zones diagrams in new Annex 3
• Reorganize former Annex 5 (Direction-indicator lamps – Geometric visibility) and incorporate into new Annex 4 as summary tables with footnotes explaining special conditions
• Update Annex 5 (Signalling panels and signalling foils) to clarify dimensions, arrangement, number and reflecting surface requirements with references to updated figures and table

The document provides follow-up information from the SLR 77th session. SLR-77-06/Rev.1 corrects errors and omissions in Reg. 150 and will supersede GRE-94-02, potentially merged with the proposal deleting UI in R150-01 for WP.29 submission in November 2026. Four baseline documents for Stage 2/Step 2 work (SLR-77-08/Rev.1, SLR-77-09, SLR-77-10, SLR-77-07 for Regs. 48, 53, 74, 86 respectively) will be submitted to GRE-94 with presentation slides. SLR agreed to keep Par. 6.21 on conspicuity marking and to renumber paragraphs 5.5 to 5.36. Old transitional provisions are documented separately. Apparent surface definition will replace light-emitting surface. Direction indicator visibility requires further study. Harmonisation text prohibits non-mentioned lamps unless compliant with national requirements. Eleven informal documents will be submitted to GRE-94.

The document considers options for the Communication form of UN R53 regarding whether to include the UN R48 series number. Option 1 retains the current form without the series number. Option 2 adopts the current Baseline document style. Option 3 adds an area in the comment section. Option 4 invites other ideas. Feedback is requested on which option should be adopted.
