 gap. The sign to diagram 606 with the "Dual carriageway" plate should be located to the left of the gap.

Signs to diagrams 606, 608 and 609 are not required where traffic joins a dual carriageway via a slip road and an acceleration lane, and the Give Way line is replaced by the marking to diagram 1010 (see figure 10-1 in Chapter 5). However, advance signs to diagram 609 and 608 might be helpful where it is not apparent to drivers that they are on a slip road, e.g. a former main road through a village joining a by-pass. Where a traffic merge warning sign is provided on the slip road (see section 2 in Chapter 4), this should be located in advance of the sign to diagram 609.



 At an unsignalled junction where a side road forms a T-junction with a two-way road (see figure 4-3) and traffic is required to turn in one direction only, the use of a sign to diagram 606, even without a "One way" plate, could be misleading as drivers might think they are turning into a one-way road. A sign to diagram 612 or 613 should therefore be used at the junction, indicating the prohibited turn.
