Signals should be clear, correctly timed and useful to other road users without creating confusion.
Use recognised signals when they are needed, give them in good time and cancel them after the manoeuvre.
These examples are for understanding and practice; they are not a promise that a particular mistake will always receive a particular grade.
Signalling so early that another road user could misunderstand your intention.
Failing to signal when it would clearly help another road user or pedestrian.
