The studs at the edge line should remain amber and the spacing should be reduced to 9m along the length of road from the first deflection arrow encountered and along the hatching. Vertical signs to diagrams 872.1/876 should also be used in advance of the taper.
4.54 Diagram 1040.4 (figure 4-14) is used to markoff an area at the edge of the carriageway which drivers should not enter unless it is safe to do so. I twill commonly be used to guide traffic past build-outs in traffic calming schemes (see section 21). The tapers are set out in table 4-6; the shape of the marking may be varied to suit the road geometry, provided that the dimensions prescribed in diagram1040.4 are maintained, and may be reversed. The boundary to the left of the hatched area may be formed by diagram 1049 delineating the off-side edge of a cycle-lane.
