The Risk of Grounding sign informs drivers they are approaching a level crossing or hump backed bridge where there may be a risk of grounding.
In the 1981 TSGRD, Risk of Grounding was a supplementary plate showing an HGV travelling over two bumps (556.3) for use with 556 "at or near a railway crossing" or 528 at a humpack bridge.
Later (when?) this was altered to have a sepcific warning sign with an HGV directly inside the triangle driving over a single hump.
