Report of the 34th meeting of the GRE Taskforce on Autonomous Vehicle Signalling Requirements held on 22 September 2026. The group reviewed a draft proposal hybrid regulation for ADS marker lamp after an editorial meeting, going through the entire document and deleting unnecessary comments. Para. 9.26 regarding substitution will be placed in square brackets for further discussion at GRE, as Japan opposes it due to lack of scientific evidence. Paragraphs 10.6.2. to 10.6.5. regarding reciprocal incorporation with direction indicators were reworked, and justification text requires further development for the formal proposal. Document AVSR-34-02 will be sent to GRE-95 as an informal document.
