Signals warn and inform other road users, including pedestrians (see ‘Signals to other road users‘), 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.
You should also
- watch out for signals given by other road users and proceed only when you are satisfied that it is safe
- be aware that an indicator on another vehicle may not have been cancelled.
You MUST obey signals given by police officers, traffic officers, traffic wardens (see ‘Signals by authorised persons’) and signs used by school crossing patrols.

Police stopping procedures. If the police want to stop your vehicle they will, where possible, attract your attention by
- flashing blue lights, headlights or sounding their siren or horn, usually from behind
- directing you to pull over to the side by pointing and/or using the left indicator.
You MUST then pull over and stop as soon as it is safe to do so. Then switch off your engine.
