DUAL CARRIAGEWAY ROADS
Plan DZA2: Approach zone for a dual carriageway road with a permanent speed limit of 50 mph or 60 mph
The principles for advance signing are:
- "road works" signs (7001) with distance plate "1 mile" (572) on the near side and the off side, placed one mile in advance of the works lead taper–these signs are always required on motorways but are not required for works on all-purpose dual carriageway roads for which relaxations apply; and
- "road works" signs (7001) with distance plate "800 yds" (572) on the near side and the off side, placed 800 m in advance of the works lead taper–these signs are not required for works on all-purpose dual carriageways or motorways that require to have 800 yds wicket signs (7202) at 800 m.

Keys to the plans are given in Tables A1.4 and A1.5 of Appendix 1.
NOTES:
- The distances on the supplementary plates refer to the location of the initial cone of the works lead taper.
- Where the lane-change zone commences with 800 yds wicket signs (7202) at 800 m, these wicket signs replace the above 800 yds "road works" signs (7001).
- On roads with a permanent speed limit of 50 mph, the 1 mile “road works” signs (7001) are only required where congestion is likely.
