5.54 On dual carriageways where there are no gaps in the central reservation, it may be necessary to make a U-turn at a roundabout in order to reach a particular destination. A special map type symbol may be used; the design of this is shown in figure 5-33. This sign would replace the standard map type advance direction sign for a roundabout junction (diagram 2022) and would include destinations not associated with the U-turn. As an alternative, a standard map type sign could be provided, with the U-turn destination shown on a separate stack type sign incorporating the special U-turn arrow as shown in diagram 2035 (see section 14). Where the U-turn is associated with a traffic regulation order, a sign to diagram 2010.1 should be used in conjunction with a separately sited sign to diagram 2022.
SYMBOLS (OTHER THAN TRIANGULAR WARNING SIGNS AND REGULATORY SIGN ROUNDELS) ON MAP TYPE SIGNS
5.55 Where symbols are placed alongside a tiled legend beneath a horizontal route arm, they should normally be positioned at the opposite end to the point of the route arm. In the case of the "P" parking symbol, this will always be placed to the left of its associated legend unless it is being used in conjunction with a tourist attraction. The special rules given in para 4.8 then apply. Where the aircraft symbol is used, this should generally be placed to the right of the airport name. The position of other symbols may be varied, but only where this would improve the overall appearance of the sign.
