36. The expert for the Special Interest Group on Automated Vehicles Regulation Screening (SIG AVRS) reported on their progress (GRBP-77-17, GRBP-77-18 and GRBP-77-19). In particular, SIG AVRS had preliminary screened 21 UN Regulations under the responsibility of GRBP and identified 13 UN Regulations for further consideration. GRBP noted that the future activities would include formalization of the report and its submission to WP.29, prioritization of findings in the GRBP priority list and inclusion of further assessment of specific UN Regulations in future Terms of Reference of SIG AVRS.

37. The expert from ISO informed GRBP about a full review of the Federal Motor Vehicle Safety Standards (FMVSS) undertaken in the United States of America for the purposes of automated driving systems (ADS). The expert from OICA recalled that the European Union had adopted an ADS framework where some UN Regulations had also been reviewed.

38. GRBP invited all experts to help SIG identify the required changes in UN Regulations and set up priorities, taking into account the priorities of WP.29 and Working Party on Automated/Autonomous and Connected Vehicles (GRVA). GRBP also noted that WP.29 had requested the Working Party on General Safety Provisions (GRSG) and GRVA to collaborate on developing new vehicle categories (or subcategories) dedicated to ADS.

39. GRBP was informed that the WP.29 Coordination Committee (AC.2) had recommended that GRBP should analyse research and establish high level principles for the possible ADS external audible signals.
