 larger areas as necessary. A sign to diagram 640.5 should be erected at each exit from the area, but if the area is small with a combined entrance and exit directly onto a public highway, this sign may be omitted.

These signs are not for use on the public highway. Loading bays on the highway should be signed using diagram 660.4 (or diagram 639.1B varied to incorporate diagram 660.4, see section 7) together with road markings to diagram 1028.3, 1032 or 1033.

A temporary prohibition of waiting is indicated by signs to diagram 636. The sign may only be placed by a traffic authority if a temporary traffic regulation order has been made, or for up to seven days by the police in an emergency. The prohibition may temporarily revoke an existing order or impose an order where no order was previously in force.

The name of the traffic authority or police force responsible for the sign, or the word "Police" or "POLICE" may be added above or below the roundel. As the prohibition applies at all times that the sign is displayed, there is no permitted variant to allow the addition of a time period or the days of the week. An arrow may be added to indicate the start of the prohibition. This should be placed below the roundel. The yellow background does not have a prescribed shape as this depends on the method of mounting (see working drawing P 636). The yellow background does not have a border. The sign is prescribed in two sizes; 275 mm diameter for use on portable stands or trestles, and 200mm, which is the maximum that will fit on a three—sided "cone". The sign must not be mounted on a curved surface.

The sign to diagram 636.1 is used to indicate a temporary prohibition of loading. Where there is a permanent 24-hour prohibition of waiting indicated by double yellow lines, the sign is used on its own. Otherwise there is likely to be a temporary prohibition of waiting and the "No loading" sign would be combined with the temporary "no waiting" sign as shown on working drawings P 636 and P 636.1 (see para 1.9).

Yellow road markings are not used with these signs, although any existing markings (and signs) will of course be left in situ. However, if the temporary prohibition is likely to last for several months, consideration should be given to providing more permanent signs, together with appropriate road markings, in accordance with para 6.6. If the temporary prohibition applies for part of the day only (e.g. when works are in progress), signs and markings should be provided in accordance with para 6.9. Where it is not possible to provide road markings (e.g. because works are taking place on the carriageway), the temporary 24-hour prohibition signs to diagrams 636 and 636.1 should be used. 49
