SIGNING PRINCIPLES

This sign should be located on the near side verge 1 mile upstream of the works, for both routine and minorworks. The distance plate may be replaced with a plate of the type shown in diagram 570. The diagram 7001 sign and distance plate may be omitted.

Lane closure information signs should be used only where they can be located safely and where they do not distract from or obscure warning, regulatory or other essential traffic signs. They should not be used if the safety considerations described in paragraphs D4.13.12 to D4.13.16 below cannot be met. Signs erected to inform the travelling public why work is suspended, or the reason for the apparent site inactivity, should be removed as soon as they cease to be applicable.

Reason for lane closure. This sign should be located within the road works site, behind the line of traffic cones and barriers and be visible to road users, when there are lane closures and when no work activities are apparent for a set period. Generally, this sign should only be displayed when the set period exceeds one day.

NOTE: see working drawings for correct design of Styles A and B

The objective in using information signs is to allay driver concern that lanes are being taken out of operation unnecessarily. It is the situation on the work site that should be the deciding factor concerning whether signs should be displayed and the number required. All signs must accurately reflect the reason for the inactivity, they should not be used to excuse poor planning or inefficient work practices.

Care should be taken in the siting of information signs to ensure that they do not represent a distraction to drivers. Road works are an obstacle in the road and drivers must concentrate on the driving process when changing lanes or carrying out lane diversion manoeuvres to negotiate the temporary traffic 106
