 55. For this we recommend the mandatory arrow at figure 12 with the words 'One way' on a plate below it (figure 12a).

56. This sign is used on roundabouts. We recommend that it be replaced by a sign as at figure 12 ( see also paragraph 110).

57. This injunction should be given by the sign at figure 14 which should be placed at the beginning of the dual-carriageway's central reservation and should normally be of the largest permitted size (Appendix VI). Where the road alignment is such that there may be danger of vehicles entering the wrong carriageway the mandatory arrow should be supplemented by a No entry sign placed on both sides of the prohibited carriageway.

58. This should be indicated where necessary before the junction by the sign at figure 13. The sign at figure 12 is for use at the junction on the central reservation. Both should be supplemented by the plate at figure 13a.

59. This sign is used to indicate that the road straight ahead carries one-way traffic. We recommend that the message be conveyed instead by the informatory sign shown at figure 97 placed on the central refuges or, where there are no refuges, by a forward pointing informatory arrow (figure 98) place on either side of the road alternately along its length.

One-way streets should be indicated by the following signs:—

(i) a mandatory arrow (figure 13) in side streets approaching a one- way street;

(ii) a horizontal informatory arrow (figure 99) with the words 'One way' below it at a point in the one-way street opposite a side turning;

(iii) the arrows in figure 97 on central refuges within one-way streets; and

(iv) where there are no refuges and a sign is considered necessary a forward pointing informatory arrow (figure 98).

60. The present rectangular sign is used at the side of a three-light traffic signal. We recommend that words be avoided by adoption of the mandatory arrow sign (figure 12) lit internally. Since this sign is circular it should be placed above the traffic signals and should be of such a size as to be distinct from the signals themselves and clearly seen from a distance.

61. These are signs for use in bollards and we recommend that they should also be replaced by the sign shown in figure 14.
