New paragraphs 0.10. to 0.10.2.

New paragraph 0.10. says that Supplement 3 is introduced to take into account vehicles of categories X and Y. Paragraph 0.10.1. exempts category Y vehicles, and category X vehicles without a manual mode intended to be operated on-board the vehicle, from the scope. Paragraph 0.10.2. lists three manual modes considered for vehicles of category X equipped with a manual mode. Category X vehicles with manual operation by a Remote-Control device intended to be operated in close proximity of the vehicle are exempted from the scope. For manual operation seated in a driver’s seat, the general provisions of this UN Regulation apply. For manual operation onboard the vehicle other than seated in a driver’s seat, for example standing while using a joystick, alternative provisions apply.

Supplement 3 to the original version of UN Regulation No. 167 is introduced to take into account vehicles of categories X and Y.
The UN Regulation was originally drafted for vehicles with a driver and manual driving controls. In the absence of a driver in the vehicle, there is no need to fulfil any of the requirements of this UN Regulation and therefore vehicles of category Y as well as vehicles of category X that do not have a manual mode, intended to be operated on-board the vehicle, are exempted from the scope of this Regulation.

Category Y, and category X without an on-board manual mode, excluded from the scope (para. 1.3.)

New paragraph 1.3. says that this UN Regulation does not apply to vehicles of category Y. It also does not apply to vehicles of category X that do not have a manual mode, intended to be operated on-board the vehicle. Paragraph 1.1. now says “This UN Regulation” instead of “This Regulation”. The categories M2, M3, N2 and N3 in paragraph 1.1. do not change. Paragraph 1.1. has a new footnote 1: “As defined in the Consolidated Resolution on the Construction of Vehicles (R.E.3.), document ECE/TRANS/WP.29/78/Rev.8”.

This UN Regulation does not apply to vehicles of category Y and to vehicles of category X that do not have a manual mode, intended to be operated on-board the vehicle.
This UN Regulation applies to the approval of vehicles of categories M2, M3, N2 and N3 with regard to their Direct Vision to reduce blind spots to the greatest extent possible, considering the needs of the specific type of vehicle and the operation it is intended for.

Alternative requirements for vehicles of category X (para. 5.1.3.) and “Safety Concept” definition (para. 2.31.)

New paragraph 5.1.3. covers vehicles of category X with a manual mode intended to be operated on-board the vehicle not using a driver’s seat. These vehicles may fulfil alternative requirements, in agreement with the Technical Service and Type Approval Authority. The condition: the manufacturer, with the safety concept defined for manual operation, can demonstrate a level of safety equivalent to the requirements of paragraph 5. The alternative provisions that are applied and the vehicle’s performance must be duly described in the Test Report. New paragraph 2.31. defines “Safety Concept”.

Vehicles of category X with a manual mode intended to be operated on-board the vehicle not using a driver’s seat, may fulfil alternative requirements, in agreement with the Technical Service and Type Approval Authority, provided that the manufacturer, with the safety concept defined for manual operation, can demonstrate that a level of safety, equivalent to that of the requirements set out in paragraph 5, is achieved. The alternative provisions that are applied and the vehicle’s performance must be duly described in the Test Report.
"Safety Concept" means a description of the measures which ensure safe operation under fault (functional safety) and non-fault conditions (operational safety) in such a way that it is free of unreasonable safety risks to the vehicle occupants and other road users. The possibility of a fallback to partial operation or to a backup system may be a part of the safety concept.

Approval mark: Unique Identifier option deleted (para. 4.5. and Annex 3)

Under paragraph 4.5., the international approval mark now consists of a circle surrounding the letter “E”. Before, the mark could consist of either this mark (para. 4.5.1.) or an oval surrounding the letters “UI” followed by the Unique Identifier (para. 4.5.2.). Paragraphs 4.5.1. and 4.5.2. are deleted. In Annex 3, one figure and the text that explains the Unique Identifier example are deleted. The Annex 3 example text now names UN Regulation No. 167 instead of “XXX”.

There shall be affixed, conspicuously and in a readily accessible place specified on the approval form, to every vehicle conforming to a vehicle type approved under this Regulation, an international approval mark consisting of a circle surrounding the letter "E" followed by:

References to M.R.1 and R.E.3 (paras. 2.13. to 2.15. and footnotes)

Paragraph 2.13. now says “as defined by Addendum 6” instead of “as defined Addendum 6”. The footnote to paragraphs 2.13. to 2.15. is now footnote 2. The footnote on the distinguishing numbers of the Contracting Parties to the 1958 Agreement is now footnote 3. It now cites document ECE/TRANS/WP.29/78/Rev. 8 instead of Rev.7.

"Three-dimensional reference system" means a coordinate system as defined by Addendum 6 of Mutual Resolution No. 1 (M.R.1). In this framework the longitudinal axis of the vehicle is designated the X axis, the lateral axis is the Y axis and the vertical axis is the Z axis.

Q2Why it changed

Expert from the Kingdom of the Netherlands on behalf of the Task Force on Automated Vehicles Regulatory Screening
Working party
GRSG, 131st session (April 2026)

Reasons

  • Supplement 3 to the original version of UN Regulation No. 167 is introduced to take into account vehicles of categories X and Y.

    Source
    “Supplement 3 to the original version of UN Regulation No. 167 is introduced to take into account vehicles of categories X and Y1”
  • The proposal was submitted to introduce amendments related to Autonomous Driving Systems (ADS) in the original version of the UN Regulation.

    Source
    “The present proposal has been submitted to introduce amendments related to Autonomous Driving Systems (ADS) in the original version of the UN Regulation.”
  • The UN Regulation was originally drafted for vehicles with a driver and manual driving controls. In the absence of a driver in the vehicle, there is no need to fulfil any of its requirements. Therefore, category Y vehicles, and category X vehicles without a manual mode intended to be operated on-board the vehicle, are exempted from its scope.

    “The UN Regulation was originally drafted for vehicles with a driver and manual driving controls.”
    “In the absence of a driver in the vehicle, there is no need to fulfil any of the requirements of this UN Regulation”
    “therefore vehicles of category Y as well as vehicles of category X that do not have a manual mode, intended to be operated on-board the vehicle, are exempted from the scope of this Regulation.”
  • Paragraph 0.10.2. considers manual operation onboard the vehicle other than seated in a driver’s seat, for example standing while using a joystick. Such a vehicle cannot meet certain provisions related to the driver’s seat and its R-point. Therefore, alternative provisions apply.
