4.4 The design of the arrow is shown in figure 4-4. The length of 16sw is reduced to 14sw, by shortening the shaft, when a vertical arrow is used with a single line legend (tiles or panel). If the single line contains a symbol with a height greater than 14sw, or the panel height exceeds 14sw (because the panel includes a symbol), then a 16sw arrow should be used.
4.5 Figure 4-5 shows how the arrow may be inclined to suit the direction being indicated. Arrows may be vertical or horizontal or at any angle between in increments of 22.5°. Arrows shown in broken outline are used only in special circumstances. A special arrow may be used to indicate U-turns (e.g. at a roundabout on a dual carriageway); further details are given in section 14.
4.6 Where a sign has more than one directional panel, as shown in figure 4-6, the arrows should indicate the general direction of the individual route and ideally be at least 45° apart. Most junction layouts can be signed using the arrows shown with a continuous outline in figure 4-5. A vertical arrow should normally be placed on the left hand side of an advance direction sign. It may be placed on the right hand side of a rectangular direction sign. Further guidance is given in Local Transport Note 1/94: The Design and Use of Directional Informatory Signs (to be superseded by Chapter 2).
4.7 Figure 4-7 shows the design of signs which include both tiled and panelled legends. The tiles or panel will be 2.5 sw from the top border, with a space to the bottom border of 1.5 sw for tiles and 2.5sw for a panel. All destination blocks (tiles, panels and patches) are ranged left irrespective of the direction in which the arrow points.
4.8 Route number patches and symbols are treated the same as panels in determining the height of the sign. Symbols (other than warning triangles and regulatory roundels) are generally positioned at the opposite end of the legend to the arrow. In the case of the "P" parking symbol, this should always be placed to the left of its associated legend unless this is the name of a tourist attraction. The "P" symbol should then be placed between the legend and the tourist attraction symbol (if any). Where there is no tourist attraction symbol, the "P" symbol should
