As per the UK Highways Traffic Sign Manual Chapter 3 - Regulatory Signs page: 50 The following advice is given:

5.6.1.  The sign to diagram 622.4 (S3‑2‑15, see Figure 5‑15) gives effect to an order prohibiting articulated (defined in Schedule 1) or track laying vehicles from a length of road, with the legend reading “No articulated vehicles” or “No track laying vehicles” as appropriate. The signs would be used where, because of their physical nature, roads are not suitable for such vehicles. It is therefore a physical limit rather than an environmental limit and for this reason no “exception” plate legends are prescribed for this sign. The only plate legend that may be used is “Ice” or “Snowdrifts” (S3‑3‑6) (see also Chapter 4).
