Norwegian request for GRRF comments on protection of steering gear and attachment to heavy vehicle frames. In a collision in Norway, the steering gear detached from the vehicle frame following a frontal collision such that the driver could no longer control the vehicle. Norway seeks input on strengthening the protection of steering gear in order to avoid such a situation.

The European Agreement Concerning the International Carriage of Dangerous Goods by Road (ADR) requires vehicles to be equipped with a speed limitation device compliant with UN R89. UN R89 refers to speed limitation devices (SLD) and speed limitation functions (SLR) (i.e., aims to be technologically neutral). Russia requests GRRF confirmation that compliance with UN R89 can be achieved through either an SLD or SLF.
