SIGNS FOR ROAD WORKS

13.12 The horizontal space between arrow centres should be increased (a) where the width of the sign is depends on which two diagrams from 7280 to 7288 determined by either the top or bottom panel, or inclusive are next to each other. The table in (b) where an increase in the horizontal spaces figure 13-4 shows the appropriate spacings for each improves the sign layout. Figure 13-5 details the combination, together with the distance to a side minimum gap between various elements and the top border or lane line. These are minimum values, and border, panel divider or horizontal bar.

NOTES The above dimensions are minimum values. They may be increased to improve the appearance of the sign or where either the top or bottom panel determines the width of the sign. Measurements are taken from the centre line of each arrow, the inside edge of any sign border, or the edge of any lane line, central reservation symbol or red block representing the closed area of carriageway. In the case of diagrams 7285 and 7286 the measurement is made from the edge of the tile block. In the case of diagram 7287 the measurement is taken from the centre line of the shaft.
