 Mileage tiles on adjacent lines may overlap horizontally (e.g. "10" and "21/2"). Where more than one distance is 10 miles or greater, the "tens" column is centred in the same way as the "units" column. This may result in a gap between some tiles making up a distance of two figures. The "3" in the lower sign panel is shown as being on the same centre line as the numerals in the upper sign panel. This is optional, and is recommended only where the shortest horizontal space between the destination and distance in any one sign panel does not extend too far beyond 7sw. The effect on the overall appearance of the sign should be the deciding factor. See paras 3.32 to 3.36 for use of distances.

(b) Fractions are not used for distances greater than 3 miles (see para 3.34).

(c) Destinations are generally ranged left. However where a destination of two or more words, such as "Millington Green", is placed on two lines, these are centred horizontally.

(d) Where a motorway number is in the form "A1(M)", the gap between the last numeral and the bracket before the "M" is 1 sw. When the motorway number is bracketed the tiles of the two adjacent closing brackets are butted together.

(e) The "g" tile of "Elkington" is horizontally within 2.5 sw of the "(A41)" patch and hence the vertical gap (line spacing) is 1 sw (see para 3.24).

Figure 4-12 shows how triangular warning signs are added to stack type signs. The triangle is always placed on the same side of the legend as the arrow. Where the sign has a green, blue or brown background a white edge is added to the outside of the triangle. The appropriate heights for the triangles (excluding any white edges) are given in Appendix D. A distance plate to diagram 572 may be added below the triangle, as shown in figure 4-12. The plate is designed as a normal sign and then reduced to 80% of its size. Thus if the x-height of the main sign is 100 mm, the x-height of the plate will be 80mm. Where the plate is placed on a green, blue or brown background the border is omitted, the corner radii remaining at 1.5sw based on the plate x-height (i.e. 1.2 sw based on the x-height of the main sign).

Where a destination is shown on a panel, the warning triangle is also included in that panel.

Where a destination is indicated to the right, any distance is generally placed to the right of the warning sign. However, where more than one destination is shown, the clarity of the sign is improved by placing the distances to the left of the warning triangle, as shown in the top diagram of figure 4-12. 36
