As per the UK Highways Traffic Sign Manual Chapter 4 - Warning Signs page: 60 The following advice is given:
11.1.1. The uneven road sign, diagram 556 (S13?2?5, see Figure 11-1), is used to warn of danger arising from longitudinal or transverse irregularities in the road surface which at the normal speed of traffic might seriously impair control of a vehicle. The use of this sign should generally be regarded as temporary, pending remedial work to the carriageway. It should be removed when the defect has been remedied. A plate to diagram 511 “REDUCE SPEED NOW” and also a plate “For” and a distance may be used with it. The uneven road sign should not be used at level crossings where the rail levels make the road uneven; diagram 782 is used for this purpose.
