As per the UK Highways Traffic Sign Manual Chapter 4 - Warning Signs page: 55 The following advice is given:

9.5.1.  The sign to diagram 553.1 (S2‑2‑34, see Figure 9-13) may be used wherever farm tractors or other agricultural vehicles frequently travel in the road at low speed, turn into or out of an entrance or cross a road. It may be particularly appropriate where visibility of an access or of turning vehicles is inadequate, or where such vehicles turn unexpectedly across high‑speed roads. The sign must always be used with a plate which may read “Farm traffic”, “Wide vehicles” or “Tractors turning” (see Figure 9-14). Where there are two entrances between which vehicles regularly travel, an indication of the distance over which the hazard extends may be added to the plate, e.g. “for 250 yds”.
