Highway Code Rule 103
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.
Highway Code Rule 104
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.

Highway Code Rule 114
You MUST NOT
- use any lights in a way which would dazzle or cause discomfort to other road users, including pedestrians, cyclists and horse riders
- use front or rear fog lights unless visibility is seriously reduced. You MUST switch them off when visibility improves to avoid dazzling other road users (see Rule 226).
In stationary queues of traffic, drivers should apply the parking brake and, once the following traffic has stopped, take their foot off the footbrake to deactivate the vehicle brake lights. This will minimise glare to road users behind until the traffic moves again.

- slow down, and if necessary stop, if you are dazzled by oncoming headlights.

Only use them for long enough to ensure that your warning has been observed.
