Wrap-up of the 21st ADS IWG and 19th GRVA Workshop on ADS Brussels session held 14-17 July 2026. The session discussed and accepted numerous proposals to amend the Guidance Implementation Document (GID) for GTR 26/UNR 185, including modifications to introductory text, safety risk management requirements, reporting provisions for various operational issues, and safety management system guidance. The session also discussed activities for ADS IWG Phase 2 (2026–2029), including remote assistance, ODD description, external HMI, feature activation and deactivation, connectivity, software parameter adaptation, ADS/ADAS transition, DSSAD, ISMR, leading metrics, safety case, text improvement, implementation, system updates, MRC, priority vehicles, STU, and end-to-end technologies.

Status report on the ADS Workshop since the 25th GRVA, covering two meetings held in June and July 2026. Task 3 addressed interpretation and guidelines, with nearly 60 change requests discussed and concluded during the Brussels meeting. Four types of changes were needed to GRVA/2026/24: consolidation of approved changes, addition of GTR version references, revised number formatting, and editorial improvements. Two informal documents are provided for clarity: a clean revision (GRVA-26-09e) and a listing of substantive changes (GRVA-26-09a1e). The workshop seeks GRVA approval for submission to WP.29 in November 2026 for adoption in March 2027. The revision applies alphabetical headings aligned with ADS regulations structure, alphanumeric subheadings for explanations, and deletes consecutive numbering to avoid confusion with GTR and UN R185 paragraph numbers.

Status report on activities of the IWG on CS/OTA since the 25th GRVA session. The IWG reviewed proposals for amendment of UN R155 and its interpretation document for multi-stage vehicles, proposals for approval-authority arrangements and Certificates of Compliance for UN R155 and R156, proposals integrating software identification and update text across several UNRs outlined in RE.3, component and STU approval concepts, and remote operation and automated driving systems. The IWG proposes updating regulatory text and interpretation documents for UN R155, revisions to software identification and update text across several regulations, and revised Terms of Reference for a mandate till November 2029.

Proposal to amend paragraph AI to introduce a link between existing text in Part A and new Part C regarding vehicle transformations, insert new Part C providing guidance for the application of UN Regulation No. 155 to transformed vehicles including documentary evidence requirements, and add section 6 clarifying that the requirement for Certificate of Compliance and type approval to be issued by the same Approval Authority applies only within the scope of a specific type approval and its approval holder.

Proposal to renew the terms for the Informal Working Group on Cyber Security and Software Updates under GRVA. The IWG shall maintain official documents on cyber security and software updates, develop amendments to UN R155 and UN R156 including provisions on software identification, support application across Global Technical Regulations, and provide opportunities for participants to share implementation experience. The IWG will be chaired by the United Kingdom, United States, and Japan, with OICA providing technical secretariat, and will operate until November 2029.

Document explains concerns about the approach in GRVA/2026/30 to require a single Approval Authority to issue certificates of compliance for Cyber Security Management Systems and Automated Driving Systems Management Systems and vehicle type approval. The proposed changes would lead to double or triple approvals of management systems, creating administrative burden and unresolved legal consequences regarding challenged certificates of compliance and their effects on other issued certificates for the same management system. The submission proposes clarifying existing wording, documenting implications of challenged certificates, and adding a new paragraph 5.1.5. to UN R155 permitting mutual agreement between Approval Authorities regarding certificate usage.

Proposal to amend Article 2, paragraph 2 to clarify that where a Certificate of Compliance required under a UN Regulation and issued by an Approval Authority of another Contracting Party is accepted by a Contracting Party, the Approval Authority granting the corresponding type approval shall remain responsible for all aspects of that type approval. The amendment addresses management systems and their Certificates of Compliance used in UN Regulations such as UN R155 and UN R156.

Clean work-in-progress draft proposal to insert a new para. 0 establishing an introduction for vehicles of categories X and Y equipped with an Automated Driving System, and amend para. 6.1.5. to clarify that the exemption for sensors, cameras, and radar devices being part of driver assistance systems does not apply to automated driving systems unless the ADS performance of the DDT is not affected.

Clean work-in-progress draft proposal to amend para. 0 to introduce provisions for vehicles of category Y and vehicles equipped with an Automated Driving System, amend para. 1.4. to specify that the Regulation does not apply to vehicles of category Y and to exempt certain vehicles of category N₁, amend para. 2.8. to define the bonnet rear reference line for vehicles of category Y without a windscreen, amend para. 2.22. to include automated driving sensors in the definition of front structure for vehicles of category X and Y, amend para. 2.29. to specify normal ride attitude for vehicles of category X and Y, amend para. 2.32. to define side reference lines for vehicles of category Y without A-pillars, amend para. 2.44. to define windscreen test area boundaries for vehicles of category Y without a windscreen, amend para. 2.45. to specify cowl monitoring area for vehicles of category Y without a windscreen, and amend para. 5.3.1.2. to modify requirements for Actively Regulated Hydro-pneumatic Suspension System when an Automated Driving System feature is active.

Based on AVSR-31-03/Rev.2 and GTBWGSL 7201, this work-in-progress draft proposes a new UN Regulation for ADS Marker Lamps. The proposal applies to vehicles of categories M, N, L₆, L₇, and O. It establishes approval procedures for ADS Marker Lamp components and vehicle installation requirements if fitted on a vehicle (the draft includes a tentative statement that nothing prevents prohibiting the use of ADS marker lamps). Key provisions include luminous intensity requirements with day-time and night-time levels for front (AMF), rear (AMR), and side (AMS) lamps; blue-green colour specifications; approval marking and labelling requirements; geometric visibility angles; electrical connections ensuring automatic activation when automated driving systems perform the dynamic driving task; and conformity of production procedures. Outstanding discussion items requiring guidance include vehicle category applicability, day-time and night-time condition definitions, reciprocal incorporation with direction indicators, alternative roof-mounted lamp options, and specification details for side marker lamp categories. Testing procedures for light sources and automatic switching conditions between day-time and night-time modes are included in annexes.

Draft agenda for the 34th meeting of the GRE Taskforce on Autonomous Vehicle Signalling Requirements, to be held via WebEx on 22 September 2026.
