The principles for advance signing are:


 * if queues are expected to extend more than two miles from the works, "road works" signs (7001) with distance plate "3 miles" (572) on the near side and the off side, placed three miles in advance of the works–further signs with distance plate "4 miles”, "5 miles" etc. should be placed as appropriate if queues are expected sometimes to extend this far;
 * a "road works ahead" sign (7004), incorporating the "road works" sign (7001) with distance plate "2 miles" on the near side, and a "road works" sign (7001) with distance plate (572) on the off side, placed two miles in advance of the works; and
 * a "road works ahead" sign (7005), incorporating the "road works" sign (7001) with distance plate "1 mile" on the near side, and a "road works" sign (7001)with distance plate (572) on the off side, placed one mile in advance of the works.

On dual carriageway roads with carriageways of five lanes or more when the works require closure of the near side lane(s), subject to certain flow limits (see paragraph D6.13.11), the "road works" sign (7001) on the off side of the carriageway may be omitted.

Keys to the plans are given in Tables A1.4 and A1.5 of Appendix 1.

NOTES: 171
 * 1) The distances on the supplementary plates refer to the location of the initial cone of the works lead taper.
 * 2) Where queuing is not expected the 3 mile "road works" sign is not required, and where in addition a relaxation applies the advance signs signing may be omitted and replaced with 1 mile "road works" signs (7001), as shown on Plan DZA2.
