6.13 Any triangle or roundel should be placed to the left of the destination when the route indicated is either ahead or to the left. When the route is to the right, the triangle or roundel should be placed to the right of the destination. An example is shown in figure 6-8. It should be noted that the addition of a triangle or roundel to a single lane destination can make the sign extremely wide. In figure 6-8 it was necessary to increase the width of the two left hand lanes to ensure that the wide single lane is not greater than twice the width of the narrowest lane (see figure 6-2). The use of more than one triangle or roundel associated with the same destination is therefore not recommended.
6.14 The vertical distance between any triangle, roundel or plate and any arrow or horizontal bar below should be a minimum of 2.5 sw, as shown in figure 6-8.
6.15 Where the sign includes the "alternative route" legend, the design rules set out in paras 3.37 and 3.38 should be used.
