–¬†¬†¬†¬† vehicles of category N1, except where the driver‚Äôs position, R-point, is either forward of the front axle or longitudinally rearwards of the front axle transverse centreline by a maximum of 1¬†100¬†mm;

–¬†¬†¬†¬† impacts to the bumper test area as defined by UN R127^[1] and UN GTR No.9^[2];
