 This sign should be given a legal mandatory significance. It should be used on all minor roads at their junctions with Primary roads in rural areas, at junctions where there is a considerable volume of traffic and at any other junction at which the highway authority considers it necessary (paragraph 53).

Other mandatory signs are recommended to indicate turn right (paragraph 54), turn right, one way only (paragraph 55), keep left, one way only (paragraph 56), keep left, dual-carriageway (paragraph 57), turn left, dual-carriageway (para graph 58), turn left (paragraph 60), keep left (paragraph 61), minimum speed limit and end of minimum speed limit (paragraph 77). But one-way traffic should be indicated by an informatory sign (paragraph 59).

The range of signs to indicate one-way streets is recommended (paragraph 59).

The signs to indicate turn left and turn right should be internally lit when placed above traffic signals (paragraph 60).

The Protocol No entry sign should be used. This has no words (paragraph 64).

Signs are recommended for no right turn and no left turn. When used at signal controlled junctions these should be internally lit and mounted above the signals (paragraph 65).

The question of giving drivers a positive injunction e.g. 'turn right' rather than a negative e.g. ' no left turn' should be further studied. In the meantime the negative is preferred (paragraph 65).

Further individual prohibitory signs are recommended as illustrated in Appendix II. These indicate: prohibited all vehicles unless requiring access to premises in the road (paragraph 66); prohibited all vehicles except perambulators and hand propelled invalid chairs unless requiring access to premises in the road (paragraph 67); prohibited public service vehicles (paragraph 68); prohibited locomotives, tractors, heavy motor cars and motor cars with seats for more than 15 persons, unless requiring access to premises or land adjoining the road (paragraph 69); play street (paragraph 70); weight limit (paragraph 71); weight limit, only one motor vehicle on bridge (paragraph 72); speed limit for vehicles exceeding specified weight limit (paragraph 73); no cycling (paragraph 75); maximum speed limits and end of maximum speed limits (paragraph 76); school crossing patrol (portable sign) (paragraph 78); no overtaking (paragraph 79); no U turns, either locally or over a distance (paragraph 80); giving way at roundabouts (paragraph 81); priority to a vehicle from the opposite direction (paragraph 82).

A sign is recommended to indicate 'No stopping'. This would be appropriate for clearways. Detailed conditions in force on urban peak-hour clearways and the point where a clearway ends should be shown on plates below the clearway sign. To indicate 'No stopping' on short lengths of street or on corners yellow carriageway markings should be used rather than roadside signs (paragraph 85(i)).

A sign is recommended to indicate 'No waiting'. The periods during which waiting is prohibited should be shown in black lower-case letters on a white rectangular plate below the sign (paragraph 85(ii)). Limitations on loading and unloading should be indicated by black lower-case letters on a yellow rectangular plate below the sign (paragraph 85(iii)). When waiting is restricted to a limited
