Warning Sign/Plates

Some signs require supplementary plates explaining where the hazard is, how far it is to the hazard, or for how far it extends. These generally consist of a white plate, with black borders and text, mounted beneath the sign to which they refer.

Since the Traffic Signs Manual considers a sign and its plate tobe one sign, you can see more than three signs on one pole; however, this is discouraged. Some signs may incorporate a supplementary plate if the sign has a yellow, or grey border; this is beneficial as it reduces the risk of the plate becoming misaligned. Over-use of borders, however, can lead to a loss of the impact that a border is intended to provide.

Special plates associated with particular signs are dealt with be on those signs' pages.

NOTE: If you see plates in the "permitted plates" section, the distance and arrow may be varied or omitted
