Signalling or indicating when driving is an essential safety and courtesy task, thinking that it’s not important or just forgetting leads to many an incident. For this reason, you should always signal when pulling away, even if it’s only a pedestrian who benefits from seeing your signal. If there’s no one around, then a signal is not necessary, but use caution. If you are ready to move off and notice a vehicle approaching from the rear to pass you, do not indicate off if you intend to wait for them to pass. The effect of this can cause the approaching vehicle to slow down or stop to let you pull away or swerve around you. Wait till the vehicle has passed and if all is clear, signal if necessary.
