Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable application of UN R121 to ADS vehicles, including the exemption of vehicles of subcategory Y from the requirements of the Regulation.

The supplement accounts for vehicles of categories X and Y, and vehicles with manual mode operating above 6 km/h equipped with an Automated Driving System. Scope updated: Regulation does not apply to vehicles of category Y (no occupants inside) or category X without on-board manual mode. New definition of “Safety Concept” added. Vehicles of category X with on-board manual mode not using driver’s seat may fulfil alternative requirements if manufacturer demonstrates equivalent safety level.
