The supplementary plates to diagram 563 which may be appropriate are listed in Table 4.2 below:

* If blasting is a road works activity see paragraph D4.8.3

The sign is used to warn drivers of the presence of a workforce in the road and that traffic should proceed slowly.

This sign should only be used when workers are present in the live carriageway, e.g. when setting out temporary traffic management.

The "NO HARD SHOULDER FOR 400 YARDS" sign to diagram 7015 is used in advance of the closure, where only the hard shoulder is to be occupied by the works. This sign should indicate the closure length in the units and to the tolerance given in Schedule 16 item 6.

The "sharp deviation of route" sign to diagram 7104 is used to indicate to drivers the direction of the deviation and to guard the obstruction which is the cause of the change of direction. Certain minimum sizes are prescribed but there is no maximum length. The recommended heights are given in Table A1.2 (Appendix 1). The sign may be used as a series of separate minimum lengths or in one continuous length, but it should not be used as a continuous fence or barrier parallel to a relatively straight carriageway. The black and white version of this sign to diagram 515 must not be used at road works.

The "lane closed" barrier to diagram 7105 serves as a visual and physical barrier and reinforces the need to change direction as indicated by traffic cones and other signs. This sign is then used at right angles to the line of traffic and mounted about 1 m above the carriageway. The depth may be either 150 or 300mm, refer to Table A1.2 (Appendix 1). A minimum length of 1.25m is prescribed which gives five panels, three coloured red and two white alternately. 89
