Text prepared by the International Organization of Motor Vehicle Manufacturers (OICA) to introduce the concept of “revision of approvals” in the UN Regulations under the responsibility of the Working Party on General Safety Provisions (GRSG).

At the 100th GRSG session, Germany presented the document GRSG/2011/19 to propose more demanding requirements for rear underrun protection devices on heavy goods vehicles. The target is to ensure a higher level of safety for passenger car occupants, who have a high risk to get severely or fatally injured in case of hitting the rear of a truck or trailer. This document provides a cost-benefit analysis in support of the proposal.

Proposal to introduce more stringent requirements for rear underrun protection devices.

Presentation in support of revisions to the current underrun protection vehicle specifications.

Position paper arguing for improvements in rear underrun protection.

IRU observations and conclusions regarding the German proposal (document GRSG/2013/27) to introduce more stringent requirements for rear under-run protection devices.

OICA counter-proposal to the German proposal (document GRSG/2013/27) to introduce more stringent requirements for rear underrun protection devices.

Justification for raising the stringency of rear underrun protection device requirements as proposed in document GRSG/2013/27.

CLCCR recommendation to establish an expert group to further consider the German proposal to raise rear underrun protection device (RUPD) requirements. CLCCR raises concerns over the cost-benefit and in particular, over the relative effectiveness of higher requirements across the range of vehicle categories that would be affected.
