Q1What changed25 changes
Paragraph 0.1. and renumbered paragraphs 0.1.1. to 0.1.14.
Paragraph 0.1. now reads “Introduction to the original version of UN Regulation No. 176.” Former paragraphs 0.1. to 0.14. are renumbered as paragraphs 0.1.1. to 0.1.14.
New paragraphs on Supplement 2 (paras 0.2. to 0.2.3.)
New paragraph 0.2. says that Supplement 2 is introduced to take into account vehicles of categories X and Y. It is also introduced for vehicles with a manual mode operating at speeds above 6 km/h which are equipped with an Automated Driving System (ADS). Paragraph 0.2.1.: 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 categories X without a driver’s seat and vehicles of category Y are exempted from the scope of this Regulation. Paragraph 0.2.2. says that vehicles equipped with an ADS must comply with this UN Regulation when operated manually by a driver from a driver’s seat. Under paragraph 0.2.3., this UN Regulation does not apply to vehicles of category X with manual driving mode operated on-board not using a driver’s seat.
Vehicles of category Y and of category X without a driver’s seat excluded (para. 1.3.)
This UN Regulation does not apply to vehicles of category Y and to vehicles of category X without a driver’s seat. Before this supplement, paragraph 1.3. said that this Regulation does not apply to vehicles not designed to be driven by a human.
FVA exception while an ADS feature is active (para. 5.1.1.)
Unless the vehicle is parked or an ADS feature is active, FVA must be driving or operation related (or both) and meet paragraph 5.1.2. onward. In the latter case, displayed non-driving related or operation related information or both must disappear within 500ms upon initiation of a transition demand, if applicable. Before, the second case was when the vehicle is performing the Dynamic Driving Task (DDT), for example as described in UN Regulation No. 157. The 500ms rule applied in that case, without the words “if applicable”.
References to R.E.3 in footnotes
Four footnotes that refer to the Consolidated Resolution on the Construction of Vehicles (R.E.3) now cite document ECE/TRANS/WP.29/78/Rev.8 instead of Rev.7. One of them says where the distinguishing numbers of the Contracting Parties to the 1958 Agreement are reproduced (Annex 3 to R.E.3). The other three footnotes start with “As defined in” and no longer refer to “para. 2.” of that document.
Q2Why it changed

- Working party
- GRSG, 131st session (April 2026)
Reasons
Supplement 2 is introduced to take into account vehicles of categories X and Y. It is also introduced for vehicles with a manual mode operating at speeds above 6 km/h which are equipped with an Automated Driving System (ADS).

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 categories X without a driver’s seat and vehicles of category Y are exempted from the scope of this Regulation.

“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 categories X without a driver’s seat and vehicles of category Y are exempted”
This UN Regulation does not apply to vehicles of category X with manual driving mode operated on-board the vehicle not using a driver’s seat. This is because a Field of Vision Assistant (FVA) system is not possible for these vehicles. This is based upon the current state of technology used for these systems.

Q3Who is affected
Vehicle manufacturer
- Check if paragraph 1.3. now excludes your vehicles of category Y, or of category X without a driver’s seat.
- Review your FVA against paragraph 5.1.1.: the exception now applies while an ADS feature is active.
Component supplier
- Make sure your FVA logic uses “while an ADS feature is active” as the paragraph 5.1.1. exception case.
Technical service / Approval authority
- Be ready to assess the paragraph 5.1.1. exception for FVA while an ADS feature is active.
