Signals for Road Users

Signals warn and inform other road users, including pedestrians of your intended actions. You should always

give clear signals in plenty of time, having checked it is not misleading to signal at that time

use them to advise other road users before changing course or direction, stopping or moving off

cancel them after use

make sure your signals will not confuse others. If, for instance, you want to stop after a side road, do not signal until you are passing the road. If you signal earlier it may give the impression that you intend to turn into the road. Your brake lights will warn traffic behind you that you are slowing down

use an arm signal to emphasise or reinforce your signal if necessary. Remember that signalling does not give you priority
