A rectangular blue or white sign bearing a single arrow, showing the only permitted direction of travel.
Also known as: One way, Arrow sign
The one-way sign shows the single direction in which a road may be travelled. It is an informative sign rather than a prohibition, which is why it is rectangular rather than a red circle.
Indicates that the road ahead may be used in the direction of the arrow only.
