Proposal to amend and supersede document ECE/TRANS/GRSG/2026/16. Supplement 1 to the 01 series of amendments to UN R166 addresses vehicles of categories X and Y. Vehicles of category Y and category X without manual mode intended for on-board operation are exempted from the scope. Vehicles of category X equipped with manual mode seated in a driver’s seat must comply with general provisions. Manual operation other than seated in a driver’s seat may apply alternative provisions. The Regulation applies to vehicles of category M₁ and N₁. New definitions of “Safety Concept” are introduced. Requirements address close-proximity front and lateral field of vision from adjusted driver’s ocular points.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable application of UN R166 to ADS vehicles, including the exemption of ADS vehicles of subcategories X and Y from the requirements of the Regulation.
