**** S is for Signalling ****
Signals are normally given by direction indicators and/or brake lights.
It's important that you use the correct signal.
To let others know what you intend to do
To help all other road users, including pedestrians
In good time and for long enough to allow other road users to see the signal and act upon it.
Signal in good time, particularly before:
Turning right or left
Overtaking another moving vehicle
Moving from one lane to another.
Signalling too soon can confuse rather than help, for example, when there are several side roads very close together.
Signalling too late can cause vehicles behind you to brake hard or swerve.
Watch out for situations which call for special timing in signalling. For example, when you signal to pull up on the left, make sure there isn't a junction just before the place you intend to stop. If you signal left too soon, a driver waiting at that junction might think that you intend to turn left. Delay signalling until you're in a position where your signal can't be misunderstood.
A signal may not be necessary where there is no-one to benefit from it, or where the signal could confuse other road users. Consider if a signal is necessary before:
Passing stationary vehicles, when you can position early and maintain a steady course.
Wave pedestrians across the road
Fail to check if the signal is cancelled after your movement is completed
Mislead other road users. Always use the correct signal
Remember: Mirrors - Signal - Manoeuvre.
Signalling with brake lights
Brake in good time. If necessary, lightly press the brake pedal early, or more than once, to show your brake lights to traffic behind you.
Flashing your headlights
Flashing the headlights can be used to warn other road users that you are there.
Avoid flashing your headlights to:
Instruct other road users
Reprimand another road user
Intimidate a driver ahead.
Other drivers flashing their lights
Some drivers flash their headlights for a variety of reasons, including:
Inviting you to pass before them
Thanking you for your courtesy
Warning you of some fault with your vehicle
Telling you that your headlights are dazzling them.
When other drivers flash their headlights, don't rely on what you think they mean. Use your own judgement; the signal:
Might not mean what you think
Might not be intended for you.
Make sure you know their intention before you act on the signal.
Remember, flashing of headlights might not be an invitation. The other driver might have flashed someone else or have flashed accidentally.
