Proposal from GRSG for a new UN Regulation to establish requirements for the approval of vehicles of categories M2, M3, N2 and N3 with regard to the driver’s direct vision to reduce blind spots to the greatest extent possible while considering the needs of the specific type of vehicle and its intended use(s).

Proposal to introduce an alternative method for assessment of the frontal visible volume to address future cab designs with narrower distances between A pillars. The current measurement method is dependent on the position of the A pillar. The alternative method is independent of the cab design and would be available for use at the manufacturer’s discretion.

Proposal to amend the requirements for the visible volume to the front of the vehicle (relative to the distance between the A-pillars or Inter A-Pillar Distance (IAPD)), to clarify that high capacity vehicles and vehicles with competing objectives do not have to meet the requirement for the Subsection Frontal Visible Volume (SFVV), and to describe how the SFVV should be calculated to take account of the reduced volume for vehicles with narrower cab designs.

Proposal to update the references to the three-dimensional H-point (3-D “H”-point) measurement and calibration procedure (per the updates and transfer of the device specification from the Consolidated Resolution on the Construction of Vehicles (R.E.3) to Mutual Resolution No. 1 (M.R.1)).
