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.
