Road signs

Circular signs with red borders indicate a prohibition or order that drivers must obey, such as speed limits or 'no entry' restrictions. In contrast, triangular signs are used to warn drivers of upcoming hazards, while blue circles usually give positive instructions.

The downward-pointing triangle shape is unique to the 'Give Way' sign, making it easily recognizable even if the sign face is covered by snow or dirt. In contrast, upward-pointing triangles are used for general warning signs, rather than instructing drivers to yield.
