Guidelines on the correct use of regulatory signs prescribed by the traffic signs regulations. These include prohibited turns, waiting and loading restrictions, bus and cycle lanes etc. There is also a comprehensive section dealing with the signing of speed limits.

v) the two lines of studs need not be at right angles to the edge of the carriageway, but they must form straight lines and, as far as practicable, be parallel to each other. iv) centres of studs in the same line must not be less than 250 mm apart nor more than 715 mm at a Zebra crossing, and not less than 500 mm nor more than 720 mm for other crossings. The centre of the nearest stud must be no more than 1300 mm from the edge of the carriageway, and i) they must be white, silver or light grey in colour and may be laid in road marking material or be conventional non reflective road studs, in which case they must not project above the carriageway by more than 20 mm at their highest point nor more than 6 mm at their edges, ii) diagram 1040.2 must be used on the approach to a staggered crossing (Schedule 4, Part I, para 3(3)).The Pedestrian Crossings Regulations permit markings to diagrams 1029 (see paras 22.26 to 22.28 and diagram 6 in Schedule 4 of the Pedestrian Crossings Regulations) and 1062 to be used at or near a crossing. The use of diagram 1062 is described in paras 21.7 to 21.16. No other marking may be used within the controlled area, except hatched and chevron markings in the circumstances described in para 15.26. Studs may be omitted at Zebra crossings, but must be provided at all other crossings. When provided, they must comply with the following requirements:

Where a crossing is situated close to a roundabout, the markings should never be extended into the circulatory area, and they should be subject to the restrictions described in para 15.20. Traffic in right hand lane of slip road joining the main carriageway has priority over left hand lane Warning signs are used to alert drivers to potential danger ahead. They indicate a need for special caution by road users and may require a reduction in speed or some other manoeuvre.

The markings at equestrian crossings (diagram 1055.2) are similar to those at Pelicans except that a second crossing place is provided for horses (see figure 15-4). Where no facility is required for other users, diagram 1055.1 is used. A comprehensive online collection of construction related standards, regulations, technical advice and articles The width of a pedestrian crossing is determined by the pedestrian flow. An extra 0.5 m should be added to the minimum width of 2.4 m for each 125 pedestrians per hour above 600, averaged over the four peak hours, up to the statutory maximum width of 10 m. At Zebra crossings, a longitudinal zig-zag line should be laid on each side of the carriageway, with another in the centre. On carriageways up to 6 m in width, the latter may be replaced with a warning line to diagram 1004. On carriageways more than 6 m wide, a zig-zag line is always used as the centre line. On multi-lane approaches, the lane lines should also be replaced with zig-zag markings. Where there is a pedestrian refuge, a double row of zig-zag markings should be used in the centre. Additional traffic joining from left ahead. Traffic on main carriageway has priority over joining traffic from right hand lane of slip road

The Pedestrian Crossings Regulations do not permit the use of central hatched or chevron markings within the controlled area of zebra crossings. Such markings may be used between a central double row of zig zags with Pelican, Puffin and Toucan crossings only in the following circumstances: Interactive training courses and educational material, to help you get the most from NBS software tools The carriageway markings used to indicate the presence of these crossings (see figure 15-2) and their controlled areas are: The Stop line to diagram 1001 indicates the position where traffic must stop when signalled to do so (see also para 3.7). The Stop line must be placed at least 1.7 m and normally not more than 3 m from the studs. This distance may be extended to a maximum of 10 m if necessary (Schedule 4 para 5(3) of the Pedestrian Crossings Regulations). On two-way roads the Stop line extends from the edge to the centre line, and on one-way roads across the full width. Where a length in the first column is common to two recommended numbers of marks, the lower number should be adopted.Crossings on minor roads close to junctions will tend to restrict the layout of the controlled area markings. To preserve the effectiveness of a junction Give Way or Stop line, the terminal line of the zig-zag markings should not normally be less than 1 m from it. This distance may be reduced to 500 mm if necessary to enable the minimum pattern of markings to be laid. The controlled area should never extend beyond the nearer kerb line of the major road. It should be the aim to provide room for at least one vehicle turning into the minor road to wait at the Chapter 2 is currently a work in progress. It will contain advice on the design and use of directional signs, and also other informatory signs such as home zone signs. Due to the amount of work required to complete chapter 2, it is intended that interim advice on individual topics will be made available as and when completed.
