COMPULSORY AND PROHIBITED MOVEMENTS side of another road, the signs should be sited in line with the backline of the major road, although they may be placed a short distance into the one-way road if this enables advantage to be taken of a convenient mounting point such as a lamp column. It may be desirable to orientate the sign to suit the direction of approaching traffic. Note that if mounted within 50 m of a junction from which traffic may approach the sign, the signs must be lit if the road is lit (Schedule 17, item 1). This also applies to junctions within the one-way road (see para 4.37). Direct lighting of the signs in these circumstances ensures that drivers can see the signs at night where the headlamps of turning vehicles are unlikely to provide sufficient illumination from retroreflection.

The ONE WAY sign to diagram 810 is an informatory sign for pedestrians. It should be used at locations where pedestrians regularly cross the road, particularly where traffic is approaching from the left. It must never be used in place of diagram 606 when aimed at vehicular traffic. At pedestrian crossing points the LOOK LEFT or LOOK RIGHT road marking to diagram 1029 may be used (see Chapter 5, paras 22.26 to 22.28).

The "no entry" sign to diagram 616 should be placed on each side of a one-way road at the point where entry is prohibited (direction 8). When the road to which the signs apply forms a junction with the side of another road, the signs should be sited in line with the backline of the major road. The signs must be placed so that one is clearly visible at all times to traffic approaching from any permitted direction; this might require a sign to be angled slightly. Care should be taken in siting the signs to avoid the possibility of drivers misunderstanding which road they apply to.

Exceptionally, at a junction where the signs apply to a side road and the carriageway of that road is less than 5 m wide (see direction 8), it might be possible to use a single sign, sited no more than 2 m from the carriageway edge, provided that it can be readily seen by all drivers who might otherwise attempt to enter the prohibited road. The Directions also permit a single sign to be used where the main route through the junction is one way, regardless of the width of the side road to which the "no entry" prohibition applies. In this case the sign should be placed on the far side of the prohibited road when viewed from the direction of travel on the main route.

The upright “no entry” signs may be supplemented by the NO ENTRY road marking to diagram 1046 (see Chapter 5, paras 22.29 to 22.32).

Where a one-way street order excepts buses, i.e. to introduce a contra-flow bus lane, the sign to diagram 953 with the plate to diagram 953.2 (Only) should be used (see para  15.21). Although the 26
