New definitions added: “Safety Concept” and “Three-dimensional reference system.” Approval marks amended to include Unique Identifier option. Alternative requirements permitted for category X vehicles with manual mode not using driver’s seat, provided equivalent safety demonstrated via safety concept. This document is intended to amend and supersede GRSG/2026/17.

Proposal to amend UN R167 to account for vehicles of categories X and Y. Vehicles of category Y and category X without manual mode intended for on-board operation are exempted from this Regulation.

Three manual modes are considered: remote-control operation near the vehicle (exempted), seated operation in driver’s seat (general provisions apply), and on-board operation other than seated (alternative provisions apply). Regulation applies to vehicles of categories M₂, M₃, N₂ and N₃. New definitions and approval mark arrangements are introduced. This document is intended to amend and supersede document ECE/TRANS/GRSG/2026/24.

Proposal to amend UN R167 to address Automated Driving Systems (ADS), exempting category Y vehicles and category X vehicles without a manual on-board mode from the regulation’s scope, while requiring ADS-equipped vehicles to comply when operated manually. Additional amendments update references to the three-dimensional H-point machine per Mutual Resolution No. 1, and revise approval marking provisions to remove the Unique Identifier option.
