Proposal to insert new introduction provisions addressing vehicles of category X and vehicles equipped with Automated Driving Systems, amend footnote 1 to para. 1.1. to reference the Consolidated Resolution on the Construction of Vehicles document ECE/TRANS/WP.29/78/Rev.8, and amend para. 2.15. to specify that for vehicles of category X, the driver’s mass is not included in unladen kerb mass calculation.

Proposal prepared by the Task Force on Automated Vehicles Regulatory Screening (TF-AVRS), with the aim to amend and supersede document ECE/TRANS/GRSG/2025/24.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable the application of UN R66 to ADS vehicles. In the absence of driver/driver’s compartment/manual driving controls in the vehicle, provisions related to them shall not be taken into account if not already covered by this amendment.

Proposal to add the definitions “escape hatch” and “emergency exit”, as well as additional requirements for the safety of living space in the bus cabin.

Proposal for to add the definitions “escape hatch” and “emergency exit”.

OICA questions the necessity of the proposed amendments as these cannot be covered
under the existing regulations for vehicle type approval

Proposal to add terms and definitions for “escape hatch” and “emergency exit”.

Proposal to introduce definitions of “escape hatch” and “emergency exit”, a test requirement for these devices, and provisions to ensure that elements that can move and enter the residual space of passengers after the bus overturning are present during testing, including provisions on fire extinguishers.

The Russian Federation considers that additional checks of a complete vehicle during rollover tests should be provided within the framework of UN R66 as an option at the national/regional level and requests guidance on whether such flexibility is permissible.

Proposal to allow additional checks on passive safety at the national level when conducting tests of a complete vehicle (such as checking for damage to seat mounts, objects presenting injury risks in the residual space, and operability of hatches).

Proposal to allow additional checks in terms of passive safety on the national level (for example, destruction of seats mounts, injury-causing objects entering the residual space and moving within it, operability of the emergency hatches).

Clarifies the verifications after the performance of the strength test.

Proposal from Russian expert to undertake additional checks in terms of passive safety

Proposal to clarify the verification procedures after the strength test. The proposal addresses destruction of seat mounts, injury-causing objects entering the residual space and moving within it, and emergency hatches.

List of items approved during the remote GRSG July session but subject to confirmation via absence of objections following the session. Under the “silence procedure”, if a Contracting Party expresses dissent, the GRSG approval is nullified.

Proposal for additional checks following complete vehicle tests:

1. destruction of seats mounts. The break-off and displacement of seats is not covered by the current Regulation, since they are initially located inside the residual space and their displacement is not assessed;
2. injury-causing objects entering the residual space and moving within it (e.g., if a person is hit by a fire extinguisher or other object when the vehicle overturns, it may cause serious or even fatal injuries).

Proposal to add checks under the current tests:

• damage to seat attachments
• occupant compartment hazards (e.g., risk of impact by loose objects such as fire extinguisher) and
• post-crash functionality of escape hatches (including force required to open)

Proposal to specify that “handrails and handholds at doorways where the associated residual space is not designated for passengers positioned for travel, and where intrusion into the space presents no risk of contact with passengers, shall also be ignored.”

Proposal to define an exemption for handles from “residual/survival space” intrusion requirements for vehicle spaces not intended for occupants. Handles and handholds used to assist passengers in entering and exiting a bus are located outside of passenger seating and standing areas where OICA argues that they do not present a danger; however, the current rollover testing provisions could result in their inclusion in the area defined as “residual/survival space” where any intrusion is prohibited.

Discussion of the state of accident statistics and other data to support the development of coach and bus safety requirements.
