Proposal to insert new paragraphs 0., 0.2. to 0.2.2. to introduce Supplement 1 to the 02 series of amendments taking into account vehicles of categories X and Y and vehicles with a manual mode operating at speeds above 6 km/h equipped with an Automated Driving System, amend footnote 1 to paragraph 1. to reference the Consolidated Resolution on the Construction of Vehicles (R.E.3.), document ECE/TRANS/WP.29/78/Rev. 8, and amend footnote 2 to paragraph 5.3.4.1. to reference Annex 3 to that document.

New paragraphs introduce provisions for vehicles of categories X and Y and vehicles with manual mode operating above 6 km/h equipped with an Automated Driving System. The regulation extends application to vehicles without driver and manual driving controls. Special provisions or exemptions do not apply to vehicles equipped with an ADS other than categories X and Y in manual or automated driving mode.

Proposal to amend UN Regulation No. 73 by inserting new paragraphs introducing Supplement 3 to the 01 series of amendments to take into account vehicles of categories X and Y and vehicles with a manual mode operating at speeds above 6 km/h equipped with an Automated Driving System. The Regulation was originally drafted for vehicles with driver and manual driving controls, and this amendment extends application to vehicles without driver and without manual driving controls inside the vehicle.

Proposal to correct cross-references in UN R73. The document amends paragraphs 12.1, 15.1, and Annex 3 paragraph 2.4 to correct invalid or non-existent paragraph references. Changes include updating references from paragraphs 12.4.4 and 15.2.4 to 12.4.2/3 and 15.2.2/3 respectively, and replacing the non-existent paragraph 2.8 reference with paragraph 12.10. The corrections do not increase requirement stringency.

Proposal to correct cross-references in UN R73. The amendments modify paragraphs 12.1, 15.1, and Annex 3, paragraph 2.4 to replace incorrect paragraph citations with accurate ones. The corrections address invalid references that do not exist or lack contextual relevance. The changes do not increase requirement stringency.

Secretariat rewrite of proposal to amends the document ECE/TRANS/WP.29/2025/104
- amends the document ECE/TRANS/WP.29/GRSG/2025/12 to ensure equal treatment of all Contracting Parties signatories to this UN Regulation.

Proposal to further take into account the impact of the modified requirement for the height of the lower edge of LPD on the Contracting Parties, including the need to adapt the infrastructure and to ensure equal treatment of all Contracting Parties signatories to this UN Regulation.

Proposal to add omitted text from the formal documents

Proposal for withdrawal based on to highlight the broader implications for vehicle design and usability for consumers resulting from this proposal. The lowering of the sideguard and reduction in ramp angle will give reduced flexibility for vehicles and trailer combinations in certain applications (i.e. loading roll-
on, roll-off vessels) and conflict with the road surface and local infrastructure (i.e. grounding out), which will lead to damage or reduced life of sideguards.

Proposal to amend the minimum height (clearance distances) of lateral protection devices for vehicles with longer distance of axle and to amend the transitional provisions to exempt Contracting Parties that apply UN R73 on or after the entry into force of the 02 series from the obligation to accept approvals granted in accordance with paragraph 11.11. of the Regulation.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable application of UN R73 to ADS vehicles.

Proposal to amend UN R73 on Lateral Protection Devices, amending ECE/TRANS/WP.29/GRSG/2024/38. The proposal adds safety requirements including a new definition of Blind Spot Information System referencing UN R151. Key modifications lower the minimum height of the lower edge of LPD from 550 mm to 450 mm for most vehicles, while maintaining 550 mm for vehicles with axle distance exceeding 6.5 m. The proposal includes transitional provisions and references GRSG-113-13. Japan and France submitted this based on traffic accident data showing reduced fatalities with lower LPD height requirements.

Proposal aims to make extendible trailers conform to all lateral protection requirements for trailers regardless of length, in order to remove the safety risk to vulnerable road users when the trailer is in the fully extended position. This is achieved by the removal of section 13.1.1. and 16.1.1 that specify some exemptions to requirements when the trailer is extended.

Proposes additional requirements for LPD installation on vehicles equipped with blind spot information systems are specified.

To improve the effectiveness of LPDs in preventing left- or right-turn collisions, Japan intends to submit the following proposals:
1. Eliminating the exemption for semi-trailer tractors
2. Reducing the lower edge ground clearance of LPDs
3. Clarifying the upper edge structure of LPDs
4. Adding exemption to ensure BSIS requirements

Proposal to amend geometrical criteria (dimensions and distances between lateral protection devices) and installation provisions for lateral protection barriers in order to improve their performance with regard to vulnerable road users. The proposal would

1. increase the maximum distance between lateral rails from 300 mm to 400 mm
2. redefine the limits for the lower edge from “550 mm above the ground” to definition via an isosceles triangle formed by lines drawn at 8° from the ground contact points of the vehicle tires intersecting at point “I” above the road surface where the maximum limit “I” is between 350-450 mm
3. define the upper edge as from 450 mm rather than 300 mm maximum from the vehicle structure or maximum height of the upper edge above the ground from 950 mm to 850 mm
4. update the horizontal static force requirement for lateral protection devices to 3 kN and the deflection under load criteria to 90 mm over the rearmost 250 mm of the device and 450 mm over the remainder of the device.

Discussion of the evolution of UN R73 with a proposal to update load requirements for lateral protection devices:

• Application of a force of 3kN perpendicular to the device (as currently defined)
• Max. strain under loading at 90mm over the 250mm most rearwards part
• Max. strain under loading at 450mm on the other parts.

Proposal to update the horizontal static force requirement for lateral protection devices to 3 kN and the deflection under load criteria to 90 mm over the rearmost 250 mm of the device and 450 mm over the remainder of the device. The purpose is to reduce the risk of running over a person (e.g., a motorcycle rider) during a lateral collision.

Proposal to amend geometrical criteria and installation provisions for lateral protection barriers in order to improve their performance with regard to vulnerable road users (e.g., lateral contact with a motorcycle or its rider(s)).

Proposal to expand the scope of the regulation by deleting paragraph 1.2.2. which allows for the exclusion of “vehicles designed and constructed for special purposes where it is not possible, for practical reasons, to fit lateral protection devices” from the text. The proposal allows Type Approval Authorities to nonetheless exempt “vehicles where any LPD (e.g. fixed, removable, foldable, adjustable, etc.) is incompatible with their on-road use” through the addition of new paragraphs.

Updated proposal, revised for clarity, to amend document GRSG/2016/2 by replacing paragraph 1.2.2. rather than deleting it. Drawing from the recently approved amendment to UN R58 (document GRSG/2015/17), this proposal would amend paragraph 1.2.2. to read, “Vehicles where any LDP (e.g. fixed, removable, foldable, adjustable, etc.) is incompatible with their on-road use may be partly or fully exempted from this Regulation, subject to the decision of the Type Approval Authority.”

Proposal to expand the scope of the regulation by deleting paragraph 1.2.2. which allows for the exclusion of “vehicles designed and constructed for special purposes where it is not possible, for practical reasons, to fit lateral protection devices” from the text. The UK submits that paragraphs 13 and 16 of the regulation provide specific provisions that address this situation whereas the exclusion clause allows for a broader interpretation that unnecessarily limits the use of lateral protection devices. Moreover, exemptions may still be accorded at the national level.

Correction of the French text only of the 01 series of amendments to UN R73.

UN Regulations Nos. 58 and 73 contain exemptions which can be applied by an approval authority and we are concerned that a vehicle which is correctly approved using such an exemption cannot then be required to have an RUPD or sideguards. The UK seeks the views of GRSG on how the wording of the exemptions may be improved to ensure that as many vehicles as possible are fitted with RUPD and sideguards.
