What should you do?
Check mirrors, signal right and turn here, giving way to oncoming traffic as needed.
How to recognise it
A blue disc with a white horizontal arrow pointing to the right.
Common confusion
Mandatory blue circles give orders, so do not confuse this with a white direction signpost that only gives route information.
