9.11 An urban clearway should be introduced only where there are no other on—street parking controls, even if they operate at a different time of day. The provision of a prohibition of waiting with time plates could be confusing to drivers as could a time—limited parking bay that operates off—peak, implying that outside those times (during peak periods) the bay can be used without limit. The only additional restriction that could sensibly be applied would be a 24-hour prohibition of waiting to protect junctions. Where other controls are required, the urban clearway should be replaced by a prohibition of waiting and loading and signed accordingly.

642.3 No stopping in lay–by except in emergency
May be used only in conjunction with diagram 7078.7
9.12 Where a lay–by has been provided for the sole purpose of accommodating an emergency telephone, an order can be made prohibiting stopping by any vehicle other than in an emergency. This prohibition is indicated by a sign to diagram 642.3 which has no permitted variants; it applies at all times and cannot include a period that is less than 24 hours or less than seven days a week. The sign must be used with the double yellow line road marking to diagram 1018.1 (direction 24(1)). Yellow kerb marks to diagram 1020.1 denoting a prohibition of loading are not used. The yellow lines should extend for the whole length of the lay–by. Normally one sign to diagram 642.3 adjacent to the emergency telephone will be sufficient; this should be orientated to face vehicles entering the lay–by.
9.13 Two sizes of sign are prescribed. The choice of x—height will depend on local circumstances. In most situations the smaller size will be sufficient. The larger size should be used where it is required to make the sign more conspicuous.

2713.1 Permitted variants indicating a lay–by for emergency use only
9.14 The sign to diagram 2713.1 is an informatory sign used to indicate to drivers approaching a lay–by that it has an emergency telephone. Where the whole lay–by is for emergency use only as described in para 9.12, the ”P” symbol is omitted as shown on working drawing P 2713.1 (see para 1.9). This sign is placed adjacent to the main carriageway where the lay–by commences and faces oncoming traffic. An advance sign, including a distance, should normally be provided approximately half a mile before the lay—by. The size of these signs depends on the speed of traffic and is shown in table 9-1.
