What should you do?
Signal and take the left turn at this point, checking for cyclists and pedestrians on your left.
How to recognise it
A blue disc with a white horizontal arrow pointing to the left.
Common confusion
The horizontal arrow means turn now; the bent arrow version means the turn is at the junction ahead.
