SIGNING PRINCIPLES

Warning of delays for specified period at road works ahead. This sign should be located on the near side verge 1 mile upstream of the works when delays of 10 minutes or greater duration are likely. The sign should be used in conjunction with the above 2 mile sign and should be used to indicate the period over which traffic delays are likely to occur. The date legend must reflect the most accurate information available. The sign to diagram 7001 and the distance plate may be omitted.

At least ten working days prior to the end of the carriageway restriction the date should be specified more precisely and updated, as necessary, until the restrictions are removed. The year may be omitted in the final stages of the works when the date is known precisely.

Lines 3 and 4 may be omitted on short-duration contracts; see working drawing.

Line 4 detail:
 * Day: 1 to 31. Included when the precise date is known, particularly during the final stages of the work.
 * Month may be abbreviated: Jan, Feb, Mar, Apr, May, June, July, Aug, Sept, Oct, Nov, Dec.
 * Year may be abbreviated: 09, 10 etc. Year may be omitted when day and month are included.

Where there are no delays anticipated the sign will be replaced by the "road works" sign to diagram 7001 with a 1 mile distance plate.

On wide carriageways where two or more lanes merge, consideration should be given to replacing the sign with a "lane closed ahead" sign (wicket sign) to diagram 7202 with a bottom integral panel to diagram 7208 varied to "1 mile". 105
