There may be occasions when it is required to show both a regulatory and a triangular warning sign on the same destination panel. The horizontal space between the two signs is the same as for stack type signs, as shown in figure 4-17. The diameter of the roundel and the height of the triangle should both be the same, based on the size of the larger sign as listed in Appendix D. The positioning of the signs on the route arm symbol should be based on the design rules for two triangles or two roundels as shown in figures 5-36, 5-38, 5-42 and 5-44. When the route arm symbol is horizontal, the centre line of the arm should pass through the centre of the roundel and not the centroid of the triangle.

A red bar, similar to the one shown in diagram 817, may be added to a stub on a map type sign to indicate "no through road". The width of the stub should always be 2.5sw, even though the route indicated may have a higher status (e.g. a short two-way section of road forming part of a one-way system). When the red bar is placed on a white background sign, a gap is provided between the bar and the stub. However, should the red bar be placed on a green, blue or brown background sign, the stub is extended to form a border around the bar. Figure 5-45 shows the detailed design of the red bar and stub.
