3 Oct 2025 UN R73: Proposal for withdrawal of GRSG-129-21 Rev 5 (CLCCR and OICA) GRSG-130-18 2025-10-03 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.
