While plenty of drivers use their horn to express anger with other motorists, there are actually strict rules around horn usage – and ignoring them could land you with a fine
We’ve all been there: you’re in a traffic jam with hundreds of other irritated drivers and all you can hear is the sound of frustrated car horns. But did you know that there are actually several situations where it is illegal to use your horn?
The Highway Code explains that the car horn shouldn’t be used in anger or annoyance – and there are a set series of scenarios in which you are allowed to use it. Under Rule 112 of the Code, you can only use the horn while your car is moving.
This means it is against the law to beep your horn while stationary. The Code also states that you must only use the horn when you “need to warn other road users of your presence”.
The RAC warns: “Using a car horn when stationary in traffic jams or at traffic lights is illegal and something that drivers cannot do – outside of emergency situations, where a collision may occur.”
Another rule many drivers are not aware of is that when driving in a built-up area between the hours of 11.30pm and 7am, it is illegal to use your horn. The only exception to this would be if another road user is posing a danger.
The RAC explains further: “A car horn is a safety device – and not something that is used to catch the attention of other drivers or as a sign of aggression. If you are caught illegally using a car horn, you could face a fine (of) up to £1,000.”
Rules surrounding a car’s horn also apply to zebra and parallel crossings. Under Rule 195 of the Highway Code, drivers should not wave, flash their lights or use their horn to invite pedestrians across.
This is because it “could be dangerous if another vehicle is approaching”. The same rule also states: “Be patient, do not sound your horn or rev your engine as this can be intimidating.”
Your car horn should also not be used when passing animals such as horses, according to Rule 214. It states: “When passing animals, drive slowly. Give them plenty of room and be ready to stop. Do not scare animals by sounding your horn, revving your engine or accelerating rapidly once you have passed them.”
The same applies if you are approaching, overtaking, or passing horse riders or horse-drawn vehicles, Rule 215 outlines. “When you see a horse on a road, you should slow down to a maximum of 10mph.
“Be patient, do not sound your horn or rev your engine. When safe to do so, pass wide and slow, allowing at least two metres of space.”
