SPEED LIMITS Figure 14-8 Full provision of terminal signs at a road junction where the side road (relevant road) has a lower speed limit than the major road

Although this exceeds the requirements of direction 9 as shown in figures 14-5 and 14-6, it is permitted and is likely to better inform drivers at many locations

Although direction 9(3) requires only one sign to indicate the speed limit in the side road (the relevant road), drivers could mistakenly think that the sign applies to the major road (the other road); the additional sign overcomes this problem

Direction 10 sets out the requirements for signing the end of a speed limit, i.e. the point where a speed limit changes to the national limit. Direction 10(4) requires a terminal sign to diagram 671, indicating that a road ceases to be subject to a speed  limit (i.e. the national speed limit applies), to be placed on each side of the relevant road or on each side of the appropriate carriageway if the relevant road is a dual carriageway (i.e. on the near side and on the central reservation) at or as near as practicable to the point where the speed limit ends. In practice, on a single carriageway road these signs would be mounted back to back with the sign to diagram 670. On a dual carriageway road, the sign on the central reservation would be mounted back to back with the sign to diagram 670, unless the reservation is very wide and the two signs need to be mounted separately, closer to each carriageway.

At a junction where the side road (the relevant road) is subject to the national limit and the major road it joins (the other road) has a different speed limit, directions 10(5) and 10(6) require one terminal sign to diagram 671 to be placed on the left hand side of the relevant road or on the left hand side of the appropriate carriageway of a dual carriageway road not more than 20 m from the major road, facing traffic turning into the side road from the major road (see figure 14-10). This is identical to the requirement for other speed limit signs as described in para 14.10. 110
