20.3.1. Diagram 782 (S2‑2‑55, see Figure 20-16 ) is used at railway or tramway level crossings where there is a risk of long or low vehicles grounding and causing an obstruction which might not be cleared before the next train or tram arrives at the crossing. It is necessary to consider both the approach profile and the relative levels of the running rails. For guidance on the use of this sign with hump bridges see 7.1 . 20.3.2. Diagrams 783 (S11‑2‑68, see Figure 20-17 ), 784.1 (S9‑4‑4, see Figure 20-18 ) and 785.1 (S11‑2‑69, see Figure 20-19 ) instruct drivers of long, low, large or slow vehicles to phone to obtain permission before crossing the railway. The smallest size of the sign to diagram 785.1 (25 mm x‑height) is intended to be read only by a driver having alighted. A larger size will be required if it is necessary for the sign to be read from a moving vehicle. As non‑compliance with the sign to diagram 784.1 could result in an accident or expose a driver to prosecution, it is essential that this group of signs is appropriately sized and properly maintained. May be used with diagram 528, 783, 785.1, 786, a distance plate with or without an arrow pointing to the left or right or an arrow alone Figure 20-16 Diagram 782 (S2‑2‑55) Risk of grounding at a railway or tramway level crossing or humped back bridge ahead May be used with diagram 601.1, 782, 785.1, 786, 787 or 788 Figure 20-17 Diagram 783 (S11‑2‑68) Drivers of long low, large or slow vehicles must telephone to obtain permission before using a railway or tram crossing (Alternative types) 81 LEVEL CROSSINGS May be used with diagram 786, 787 or 788. ”must phone” may be varied to ”must use SOS phone” The name of the crossing may be varied and displayed on any number of lines. “TO CONTACT RAILWAY” may be on one line, “RAILWAY” may be varied to “TRAM Co.” and the telephone number varied.
