Session 117 | Geneva | 8-11 Oct 2019
12. UN Regulation No. 93 (Front underrun protection)

GRSG agreed to consider a proposal by the European Commission to update the provisions on frontal underrun protection which are approved as an integrated part of the vehicle, in particular, to allow for a more rounded shape of the cab for a better aerodynamic performance, if available.

GRSG-117-36 | UN R93: Comments on ECE/TRANS/WP.29/GRSG/2019/19 Proposal to modify the scope and transitional provisions of the proposal concerning aerodynamic cabs.
GRSG-117-48 | UN R93: Proposal for amendments to ECE/TRANS/WP29/GRSG/2019/19
GRSG-117-55 | Proposal based on GRSG-117-48 Revisions to the proposal to update Part III of UN R93 to enable approval of truck cabs where the front underrun protection is integrated in the motor vehicle (in order to improve aerodynamic performance). The proposal includes transitional provisions from 1 November 2025.
GRSG/2019/19 | UN R93: Proposal for amendments Proposal to update Part III of UN R93 to enable approval of truck cabs where the front underrun protection is integrated in the motor vehicle (in order to improve aerodynamic performance). This proposal would define the forward reference point as being the same transverse location where the force is applied. This results in FUPs where (in the case of cab fronts that are curved) at least 400 mm must be maintained along the front contour of the cab, instead of the foremost point. The proposal includes transitional provisions from 1 September 2020.
