SINGLE CARRIAGEWAY ROADS
- on a three-lane single carriageway road: on the two-lane side, a "STOP/GO" board (7023/7024) on the near side opposite the end of the lead guide island and, 15m in advance of the board, a "WHEN STOP SIGN SHOWS WAIT HERE" sign (7011 variant). On the single-lane side, a "STOP/GO" board (7023/7024) half way along the lead-in taper on the near side and, 15m in advance of the board, a "WHEN STOP SIGN SHOWS WAIT HERE" sign (7011 variant).
The principles for the signing of the lead-in taper are:
- one "keep left/right" sign (610) is placed on the near side at the start of the taper,
- on a two-lane single carriageway road: coning to Detail B is used at an angle of 45° to the edge of the road,
- on a three-lane single carriageway road: coning to Detail B or C2 is used. Table 5.3 in Section [[#D5.4|D5.4 specifies the taper length and the length of the guide island is dealt with in Section D5.11;
- a "lane closed" barrier (7105) with a "keep left/right" sign (610) is placed at the end of the taper behind the cones, the "keep left/right" sign may be placed behind or in front of the barrier, and
- on a three-lane single carriageway road, when two lanes are crossed, one "lane closed" barrier (7105) with a high intensity warning light and a "keep left/right" sign (610) is placed in the closed lane.
Relaxation:
- if the shuttle lane is no more than 20m long and the "STOP/GO" board (7023/7024) is clearly visible from both directions, then only one board is required, this should be positioned either at one end or in the middle.
The principles for the work zone are:
- coning to Detail C1 is used to mark the edge of the works area on single carriageway roads, no additional signing is required.
The principles for the exit taper are:
- coning on two-lane single carriageway roads to Detail B at 45° to the edge of the road,
- the coning for the exit taper on three-lane single carriageway roads is the same as for the lead-in taper, and
- a "lane closed" barrier (7105) facing opposing traffic with a "keep left/right” sign (610), on a three-lane single carriageway road these signs are positioned on the central traffic control island.
The principles for signing at the end of the road works are:
- a "road works" sign (7001) with supplementary plate "End" (645) is located a distance E from the end of the works; see Table 5.3 in Section D5.4.
High intensity warning lights are not required where there is positive traffic control ("STOP/GO" signs, portable signals) but are required for priority signs during the hours of darkness where there is a loss of one lane or part of a lane.
