Why do drivers sound the horn to vent their anger against other drivers

Hardly ever use the horn but occasionally I beep someone if I feel that they obviously haven't realised that they have made a driving error. The last time was when a man drove onto mini roundabout in front of me without even looking, causing me to brake hard. I am sure he had no idea that he might have caused an accident. Sadly he probably still thinks that the beep was not meant for him.

My DDiL had an impatient man sound his horn then pull by her still tooting & stop in front of her. He got out of his car to have a go at what he must have assumed was a stupid blond woman driver! My DDiL got out of her car, stood up to her nearly 6 foot height & politely asked the short man what was wrong! He muttered to himself, got back in his car & vanished! My young GS thought it was hilarious because the little man was scared of his Mummy! We all agreed! He must have felt really stupid!

In Jamaica they are a form of communication. They beep if wanting to overtake and the driver being overtaken beeps in acknowledgement, then the overtaking driver will beep their thanks is one example.

Sometimes I have been warned by a horn and have warned others.
And as for dreamy drivers not moving when s filter at the lights say they can.. yes. Just beeps not blasts.
I hate the sound of horns blasted in anger it raises the blood pressure for everyone and is dangerous, I always doubly, triply check it isn’t me, causing the offence, no way, then hate them. It’s a scary aggressive tactic.
And while we are at it people who don’t acknowledge your generosity, letting them in etc really **sses me off. (And most often round here it is young women who think they are thus entitled. )

If you keep hearing a horn maybe you should check your driving?

I don't use my car horn except when I lean on it by accident getting out of the car - it's in the middle of the steering wheel. The windscreen wipers are on the stick where the horn used to be in my old car so I do a good line in washing the windscreen to show my irritation!
Pet hate is people hooting at learner drivers - we were all there once.

Possibly because by doing so the incident will stay in the mind of the ‘ alleged guilty party’. Thus hopefully avoiding repeating
the ‘mistake ‘

ha ha GrandMattie that was my immediate thought. In India it seemed to mean I'm coming and you need to get out of the way as I'm driving down the wrong side of the motorway!

Last time I used my horn I was taking my neighbour shopping, I was keeping to the speed limit At a roundabout a Mercedes driver who obviously thought I wasn't going fast enough for him decided to overtake me & pull in so sharply I still don't know how he didn't take my front wing with him, yes I did lean on the horn as it shook both of us up, such a dangerous manouver. He was last seen disappearing towards Newton Abbot at well over the 30mph speed limit

My late wife did not move off when the lights changed to green. A policeman from the car behind us came, knocked on the drivers window, and said to my wife "Can you not find a colour that you like, madam?"

We have a neighbour who regularly gets picked up by her son, before 8am. He toots the horn, why not use his mobile and stop disturbing people, unnecessarily. Or even just sit there and wait for her, why the noise?

As others have said, the horn is not just for emergencies. It can and should be used to warn others of your presence, if you think they may not be aware of you, and so prevent an accident. Eg if you are driving down the road and someone starts reversing a car off their drive into the road and may not be able to see you because of parked cars or other obstructions. As a motorcycle rider, it is horrifying to find how many car drivers think I am invisible! I was taught, particularly by the trainer on my advanced course, to let people know I am there. Tbh, the sound of a motorcycle horn is akin to an apologetic fart, but I still sound it when I think it will save my skin. On the other hand, my car horn is magnificent!

I am glad I sounded my horn last week or my mini would have been wiped out by a Volvo driver who had NO IDEA I was behind her and began reversing into me. She got a piece of my mind as well . My dad, a police officer, said use your horn to alert others of danger !!

My dad used to say that they had a horn where their brake should be!

GrowingOldDisgracefully is correct - in Law, it is an "Audible warning instrument" i.e. an auditory means of warning others of possible danger. It doesn't have to be a horn, it might be something else.
My pet hate, as referred to above, is drivers too lazy to get out of the car and ring the doorbell when they are picking up someone. Usually the same people signal their farewell when they have dropped the person, by means of a totally unnecessary 'peep-peep'. Grrrr! Mr. Driver (as it usually is a man) have you not thought there might be someone on night-shift trying to sleep; someone very unwell; a small child whose mother is trying to get him down for a nap?

I find its the hand gestures you receive too drives me nuts. If you maybe are not quick enough to move off, some impatient folk just love to show you now what they think rather than blast their horn...

Infoman - actually the horn isn't there for emergency, it's a feature on the vehicle to serve as a communication with another driver(s) to alert them to an action you might be about to perform that may have an impact on them or indeed just to alert them to something (like a back light out or a trailing exhaust). Indeed when taking a blind corner (even where there's a mirror) you should sound your horn to make oncoming vehicles aware of your presence.

I agree, used incorrectly in a moment of impulse to vent at someone who's cut you up can be annoying if you're on the receiving end, but if that were it's only function it wouldn't be a feature on the car in the first place.

I find it irritating when someone blasts their horn when passing someone they know in the street!It makes me jump and immediately think I’ve done something wrong!
A while back someone was cutting me up at a roundabout and I shouted in the car because I didn’t know where the horn was!I do now!

Some neighbours of ours have locked gates and whenever a certain friend arrives they sit in their car and constantly toot their horn until someone comes and unlocks the gates to let them in.

infoman ???

I don’t understand your post.
What does the horn is there for emergencies mean?
Do you only sound your horn constantly when you’re on an emergency run to the hospital?

When someone cuts in too close on you, starts to pull out in front of you, or a lorry is forcing you onto the hard shoulder, or otherwise endangering you, a prompt reminder often stops it turning into an emergency.

Mollygo I wished my Fiancé had sounded his horn when a lorry pulled out from a lay-by in front of us and kept coming, I was absolutely terrified and thought that we were going to die. Yes you are correct this is one time when a horn should have been used to alert the lorry driver that we were there. I don’t understand why my Fiancé didn’t use the horn.

When I read the OP I thought it was a little odd, given that it such a widespread practice. Then I read the last sentence and thought, aaah. I get it now.

The last time I used my horn was on a well used country road. I came on two cyclists, and one actually pulled out alongside his friend but onto the opposite side of the road! I beeped gently and he pulled back, allowing me to overtake. I feel completely justified in alerting him to my presence ( and his error).

I should have sounded my horn the other day at the idiot who cut me up on a roundabout. He positioned his dirty great 4x4 as if to turn right then barged in front of me to go straight on. At the next roundabout I was turning right, he was turning left and I could see him cursing and gesticulating at me. How dare a mere woman driving a little Honda try to stop him barging in! I responded with a hand signal that was NEVER in the Highway Code!

Many years ago driving on one of the circular roads round London I was tooted at madly for quite a time until eventually the offending car drive in front if me with hazard lights on and slowed down. I thought I had commuted an offence and it was an unmarked police car. Guy came to my window to tell me he had notice children's shoes flying out the rear windows. I had the windows slightly down and my twin sons in the back were posting their shoes out the little gap. The guy stopped the traffic until I ran back to collect the shoes. Not all tooting is aggressive!

The horn is primarily a 'warning' as the Highway Code states. Examples of this are cutting the other driver up, overtaking inappropriately, stepping off a pavement without looking to see if traffic is coming round the corner and so on. Many a car crash or accidents to pedestrians have been avoided in this way. A lawyer friend of mine tells me a judge deciding who is at fault in a car crash or accident, will often start off by asking if the horn was sounded as a warning. It is drivers who use it incorrectly who are in the wrong.
