 also applies where a road outside the zone has a junction with the side of a road that is within the zone (i.e. the major road at the junction is within the zone and the side road is outside the zone). Only one size of sign is prescribed, although the lower panel may be varied or omitted. The speed limit roundel must not be varied to any other speed limit. }} The end of the zone is indicated by the sign to diagram 675, with the upper panel showing the adjacent speed limit. Where this is the national speed limit, the roundel is varied to diagram 671 on a grey background as detailed on working drawing P 675 (see para 1.9). Two signs to diagram 675 should be provided, one on each side of the carriageway, unless they are placed at a junction. Reduced signing might then be possible (see paras 14.10, 14.12 and 14.15). Where the adjacent speed limit is 20 mph (without traffic calming features), the signs to diagram 675 are replaced by 20 mph terminal signs to diagram 670.

Direction 11(4)(a) does not permit a 30 mph speed limit to have repeater signs where a road has carriageway lighting (see para 14.21). Any adjacent length of road which is also lit and subject to a different speed limit, including the national limit, will have repeater signs (other than a 20 mph zone). Should an order be made to extend the 30 mph limit into this adjacent length of road, the terminal signs will be moved to the new speed limit changeover point and the repeater signs removed entirely. Regular drivers might not at first realise that the speed limit has changed; they might not notice that the speed limit signs have been removed. A sign to diagram 7032 should therefore be erected to advise drivers that a new 30 mph speed limit is in force (see figure 14-19).
