The GRE Taskforce on Autonomous Vehicle Signalling discussed Automated Driving System marker lamps, including Japanese input on Vienna Convention compliance, vehicle categories under the 1958 Agreement, mandatory rear installation requirements, variable intensity settings, daytime/nighttime definitions, side marker lamp configurations, agricultural vehicle applicability, rooftop installation alternatives, and operational conditions adjacent to direction indicators. Several technical issues remain unresolved. An informal proposal for a hybrid regulation is expected for the 95th GRE session. The next meeting is scheduled for 18 June 2026.

Proposal to amend UN R17 Supplement 1 to the 12 series of amendments. The Regulation is amended to account for vehicles of category X. Vehicles of category Y are not in the scope of this Regulation. The Regulation is extended to vehicles without driver and manual driving controls. Multiple amendments are made to definitions, test procedures, and technical requirements for seats, anchorages, and head restraints, including changes to measurement planes, test parameters, and displacement specifications across various annexes and paragraphs.

The initial regulations for Driver Drowsiness and Attention Warning and Advanced Driver Distraction Warning systems were adopted at GRSG-130 and WP.29-198. DDADWS is developing 01 series regulations, with workshops and online meetings planned. The group seeks a mandate extension to October 2028 to complete 01 series development, with proposed submission for approval to GRSG-136.

Proposal to extend the mandate of the DDADWS informal group until October 2028 to enable development of new (01) series of amendments to the original texts of the driver drowsiness and driver distraction warning systems regulations.

This document provides recommendations for DSSAD, a vehicle capability that monitors Automated Driving System (ADS) performance. It defines key terms including ADS, Dynamic Driving Task (DDT), Operational Design Domain (ODD), and Mitigated Risk Condition (MRC). The document specifies requirements for data storage, security, format, and accessibility. DSSAD must record time-stamped events such as feature activation/deactivation, ODD exits, and fallback responses, plus time-series data during triggering events like collisions, including vehicle dynamics and sensor information.

Proposal to introduce provisions for rollover protection systems, advanced emergency braking systems, vulnerable road user secondary safety systems, and driver assistance systems. Amendments clarify triggering conditions for event recording and data locking, expand data elements to capture vulnerable road user collisions and advanced safety system interventions, increase sample rates for improved data granularity, and add transitional provisions for type-approval acceptance timelines.

Proposal to amend Paragraph 1.4., Footnote 1 to update the reference to the Consolidated Resolution on the Construction of Vehicles; insert new paragraphs 2.10. and 2.11. defining “ADS user” and “Vehicle user”; amend Paragraph 5.5.2., Footnote 4 to update the reference to Annex 3 of the Consolidated Resolution; and amend paragraphs 6.1.2.4.1.6.1. and 6.2.2.4.1.6.1. to specify that engine starting-up on petrol and switching to LPG or CNG after a predetermined period cannot be changed by the vehicle user.

• Amend paras. 1.1. and 1.2. to modify the scope for Level 1A and Level 1B
• Insert Footnote 1 to para. 1.
• Amend para. 3.3. to revise the heading
• Amend para. 3.3.3. to redefine “Mass in running order” and clarify driver mass inclusion for vehicles of categories X and Y
