DESIGN ELEMENTS FOR THE CENTRE PANEL
13.11 Diagrams 7280 to 7288 inclusive show the various options that are available. The design of each of these elements is shown in figure 13-3. It should be noted that diagram 7285 is used only on signs to be placed on all-purpose roads and that diagram 7286 should be used only on signs that are placed on motorways. The alphabet used for the route number in diagram 7286 is the Motorway Black alphabet shown in Schedule 13 Part IV to the Regulations. Because the characters occupy the full tile height, the X-height is smaller than that of diagram 7285 in order to produce a more balanced overall sign layout. The top of the red bar in diagram 7287 should be positioned 300mm below the top of any adjacent arrow which forms part of any other sign element (see figure 13-7). This is to ensure a clear distinction between open and closed lanes when the sign is viewed from a distance.
