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.
The World Forum will consider the following proposals and may decide to submit them to AC.1 with recommendations on their adoption by vote.
