32. The expert from the United Kingdom and Northern Ireland, on behalf of the Task Force on Automated Vehicle Categorisation introduced GRSG-129-30, to accommodate additional definitions for ADS and DDT into the Consolidated Resolution on the Construction of Vehicles (R.E.3). The experts from Germany and the United Kingdom introduced the status report of TF-AVC (GRSG-129-27). The expert from the United Kingdom, on behalf of TF also introduced the TF status report (GRSG-129-25). The expert from the Kingdom of the Netherlands introduced GRSG-129-09, requesting the opinion of GRSG experts on the formula defining the multipurpose vehicles (MPV-AF) (derived from passenger vehicles). Finally, GRSG agreed on option 1 proposed by GRSG-129-25: P – (M + N × 68) > N × 68. Therefore, GRSG discussed GRSG-129-30, superseding ECE/TRANS/WP.29/GRSG/2025/10, to include a definition of a bidirectional vehicle and to remove any references to the 3-D “H”-point machine from R.E.3. GRSG finally considered GRSG-129-30-Rev.2 (incorporating GRSG-129-18) and adopted it as reproduced in annex VII to the report. The secretariat was requested to submit the proposal as Revision 8 to the R.E.3 for consideration and vote at the November 2025 session of WP.29.

33. Referring to the question and answer document (GRSG-129-28), provided by TF-AVC, the expert from EC questioned the insertion of the definition of a bidirectional vehicle since it was considered premature by TF-AVC (see question No. 20 of GRSG-129-28).

34. The expert from the Kingdom of the Netherlands introduced the status report of TF on Autonomous Vehicles Regulatory Screening (TF-AVRS) (GRSG-129-48), as well as GRSG-129-10, GRSG-129-11, GRSG-129-12, GRSG-129-13, GRSG-129-14, GRSG-129-16 and GRSG-129-17. This would introduce amendments to the UN Regulations Nos. 35, 43, 46, 107, 121, 122 and 125 enabling the application of these UN Regulations to vehicles equipped with an autonomous driving system. GRSG took note of the proposed amendments and agreed to resume discussion on the basis of official proposals submitted by TF-AVRS to the October 2025 session of GRSG.
