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 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.
