Before you signal, ask yourself who needs the information and whether the timing will help them. Useful signals follow proper observations and support a clear, predictable manoeuvre.
Observe first
Decide who is around you and whether a signal will actually help them understand your intention.
Time the signal
Too early can mislead; too late can be useless. Signal when it clearly relates to the manoeuvre you are about to make.
Check it cancelled
After the manoeuvre, make sure the indicator is no longer giving false information.
