a possible combination of signs and markings at a road junction. This arrangement is not intended to be used at all junctions, but may be appropriate at difficult sites where, for example, overtaking may cause a problem on the approach to a junction.
4.26 Where there are two features that would justify warning lines (e.g. two junctions, or a junction followed by a bend), then a short length of standard centre line between two warning lines can help to highlight the separate hazards, even if this results in fewer than the minimum number of marks being provided for the second hazard.
EDGE OF CARRIAGEWAY LINES
4.27 The following types are prescribed:
(i) diagram 1009 (see figure 4-6, para 4.28 and table 4-5),
(ii) diagram 1010 (see figure 4-7, paras 4.29 and 4.30 and table 4-5),
(iii) diagram 1012.1 (see figure 4-8, paras 4.31 to 4.38 and table 4-5 and, when used at level crossings, para 19.9), and
(iv)diagrams 1012.2 and 1012.3 (see paras 4.39 to 4.48, table 4-5 and figure 4-9).
4.28 Diagram 1009 should be used to extend the transverse Give Way and Stop line markings across the entry half width of the minor road as illustrated in figures 3-1 and 3-2. It is used across the full width if the minor road is one-way away from the junction. The normal width of the line is 100 mm but when it isused in conjunction with a continuous edge line, the width should be varied to match. The marking maybe used as an alternative to diagram 1010 across private driveways where the larger marking would be impracticable, e.g. because of the narrowness of the entrance. Where the width of the minor road is such that Give Way or Stop lines would be less than 2.75 m long, these should be extended across the whole width of the road (see para 3.3). The use of diagram 1009 at the start of cycle lanes is dealt with in paras 16.6, 16.8 and 16.10.
