Proposal to amend para. 5.1.1.3. to adjust the lower vertical datum point from 5 degrees to 4 degrees below the horizontal and update the corresponding figure in Annex 4, Figure 1. This harmonizes the location of the lower datum point with the angle of obstruction requirement in para. 5.1.3., resolving an inconsistency between the allowed area of obstruction and the mandated transparent area of the windscreen.

Proposal to amend UN R18, UN R39, UN R46, UN R55, UN R58, UN R67, UN R73, UN R93, UN R97, UN R102, UN R105, UN R107, UN R110, UN R116, UN R121, UN R122, UN R125, UN R144, UN R147, UN R151, UN R158, UN R159, UN R160, UN R161, UN R162, UN R163, UN R166, UN R169, UN R176, UN R181, UN R182 and UN R183:

• Add new paragraphs defining Software Identification Number by reference to Consolidated Resolution on the Construction of Vehicles (R.E.3) Annex 7, para. 2,
• amend paragraphs concerning production discontinuation to clarify that production is not considered definitively discontinued if vehicle manufacturers intend to obtain subsequent extensions of approval for software updates of vehicles already registered in the market,
• add new paragraphs requiring manufacturers to provide Technical Services with information on all hardware and software having an influence on performance,
• add new paragraphs allowing vehicle manufacturers to apply for new vehicle approvals to differentiate software versions for vehicles already registered in the market from those for new vehicles,
• add new paragraphs to approval forms requesting additional information regarding software identification and software updates, including whether Software Identification Number is held on the vehicle and relevant parameters for identification of vehicles that can be updated with the represented software.

Proposal to insert new paragraphs 0., 0.1. to 0.1.2., 1.4., 2.21., and 5.6., amend paragraph 1.1. footnote 1, paragraph 4.4.1. footnote 4, paragraph 5.1.3.4., and paragraph 5.1.3.5., based on GRSG-131-33. The supplement introduces provisions for vehicles of categories X and Y and vehicles equipped with an Automated Driving System, defines Safety Concept, addresses Field of Vision Assistant requirements, and establishes alternative requirements for category X vehicles with manual modes operated on-board the vehicle not using a driver’s seat.

Proposal for Supplement 1 to the 03 Series of Amendments to UN R125 (Forward Field of Vision), amending and superseding ECE/TRANS/GRSG/2026/8. The proposal introduces provisions for vehicles of categories X and Y, and vehicles equipped with an Automated Driving System (ADS). Vehicles of category Y without a driver are exempt from the Regulation. For vehicles of category X with manual driving modes, different provisions apply depending on operation method: remote-control operation is exempt; seated operation follows general provisions; and on-board operation not using a driver’s seat may use alternative requirements demonstrating equivalent safety levels.

Proposal to resolve a longstanding inconsistency in UN R125 between the lower datum point (§5.1.1.3, set at 5°) and the obstruction requirement (§5.1.3, set at 4°), by aligning the lower datum point to 4° while retaining upper and lateral aspects of §5.1.1. unchanged. The 5° datum point has never been used for any technical requirements beyond serving as a reference point, while the 4° obstruction requirement has prior precedent. As this is a vehicle rather than component requirement, the datum point is also proposed for deletion from UN R43, retaining it solely in UN R125.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable application of UN R125 to ADS vehicles, including the exemption of vehicles of subcategories X and Y.
