May be used only in combination with diagram 7009. The speed must not be varied
12.4 Loose chippings arising from surface dressing operations can pose a hazard either due to being thrown up into the path of oncoming vehicles or by causing vehicles to skid on the loose surface. While works are taking place, the sign to diagram 7009 should be used together with the supplementary plate to diagram 513.2, varied to indicate a recommended speed of 10 mph. On completion of the works, the sign may be retained for so long as the traffic authority considers it necessary to warn drivers (direction 36) in which case the supplementary plate should be replaced by the plates comprising sign diagram 7009.1. It is not permitted to vary the recommended speed on this sign. Further advice on signing during surface dressing operations can be found on the website of the Road Surface Treatments Association at www.rsta-uk.org/publications.htm.
