5.12.1. The sign to diagram 625.1 (S3‑2‑22, see Figure 5‑23) should be used to give effect to an order to prohibit pedestrians. It is likely to be used in urban areas where inner ring roads etc. do not have any frontage development or footways, especially where such roads include flyovers and underpasses. The sign might also be appropriate where pedestrians are able to gain access to a tram‑only route. The sign does not have a supplementary plate.
