43. The experts of the Task Force on Autonomous Vehicle Signalling Requirements (TF AVSR) reported on their activities (GRE-87-17). GRE noted the GRVA and its Informal Working Group on Functional Requirements for Automated Vehicles (IWG FRAV) recommendations on ADS external light-signalling (GRVA-14-15/Rev.3), in particular:

  • no mandatory requirements for additional light-signalling devices beyond those requirements established for manually driven vehicles.
  • existing light-signalling devices may be suitable (if permitted) to signal initiation of an automated fallback response designed to place the ADS vehicle in a minimal risk condition.
  • establishment of uniform provisions for a light signal to communicate the ADS operational status under certain conditions, should it be required or permitted by an individual contracting party.
  • continued monitoring of research into the ADS signalling and safety of interactions between other road users and ADS vehicles.

44. Awaiting final guidance from WP.29 on ADS external light-signalling, GRE requested TF AVSR to liaise with GRVA and IWG FRAV, as appropriate.
