PEDESTRIAN ZONE
20.30 Yellow lines (and kerb marks) must be used unless the conditions in direction 24(4) are met (see para 20.31) or a special direction has been issued to omit them (see para 20.32). Parking or loading bays are not normally provided, but see para 20.32(iii).
20.31 The conditions under which direction 24(4) permits the omission of yellow lines and kerb markings are where:
(i) the entry of vehicles is restricted at the same time as the waiting restrictions apply,
(ii) the footway and carriageway are not separately defined (i.e. the whole road width is paved over without change of level or material), and
(iii) the waiting restrictions apply uniformly throughout the zone.
20.32 It may be possible to issue a special direction (see para 2.1) to allow yellow lines and kerb marks to be omitted in other circumstances, for example:
(i) where the road surface is not paved but vehicles are not likely to be parked outside the times at which vehicle entry is restricted,
(ii) where the road surface is at one level, but different colours or textures of surfacing are used to distinguish the carriageway from the footway, and the other requirements of direction 24(4) are met, or
(iii) where parking and loading bays, bus stops or taxi ranks are provided within the zone, but waiting restrictions are otherwise uniform. The bays will need standard markings, or to be delineated by bollards, planters or other street furniture.
RESTRICTED ZONE
20.33 Restricted zones generally use vertical signs to restrict parking, with no yellow line markings. They are signed using a specially authorised variant of diagram 663 with the legend "Restricted ZONE" and the words "Except in signed bays" added where appropriate. White bay markings (diagrams 1028.3 or 1028.4) or yellow bus stop or taxi markings (diagrams 1025.1, 1025.3, 1025.4 or 1028.2) will be used if required. They need not be used if the bays are physically delineated by kerbs, bollards, planters or other street furniture.
LORRY AND BUS PARKING BAN ZONE
20.34 Where it is desired to ban parking by large vehicles for part of the day in residential areas, lorry or bus parking ban zones may be introduced. Such zones are effected using upright signs to diagrams 640.2A and 665, without the use of road markings.
CYCLE AND BUS LANES
20.35 The use of yellow lines in cycle lanes is dealt with in para 16.7, and in bus lanes in para 17.11.
