Signalling
Communication
Signals communicate your intentions to other road users — drivers, cyclists, pedestrians, riders, and even road workers.
Always signal clearly and in good time.
Use only the signals shown in The Highway Code.
Direction Indicators
Use indicators to show your intentions early enough for others to see and react.
Position your vehicle correctly for the manoeuvre you intend to make.
Avoid signalling too soon — for example, don’t signal left before a junction if you plan to stop just after it. Other drivers may think you’re turning and pull out into your path.
If another vehicle is signalling to turn, don’t rely on that signal alone — wait until you’re sure they are actually turning.
The Horn
The horn is a warning, not a weapon.
It doesn’t give you priority or excuse unsafe driving.
Use it only:
-
To warn others of your presence, especially at blind bends or junctions
-
When you think another road user hasn’t seen you
Avoid long blasts, and don’t use the horn near animals or at night in built-up areas (between 11:30 p.m. and 7 a.m.), unless there’s danger.
Never use it to express annoyance or attract someone’s attention.
Flashing Headlights
Flashing headlights means the same as sounding the horn — to let others know you’re there.
Never flash to tell someone to go or turn.
If someone flashes at you, don’t assume it’s a signal to move. Ask yourself:
-
Is it safe?
-
Is the signal really for me?
-
What might happen if I move now?
Warnings on Dual Carriageways & Motorways
If you need to warn another driver, flashing your headlights is usually safer than using the horn.
If a vehicle behind flashes or tailgates you, stay calm.
Do not react — simply move back to the left when it’s safe.
Remember: the only official meaning of flashing headlights is to tell others “I’m here.”
