Some people are so impatient and use their vehicle horn agressuvely. Like wherever they’re going is so important the rules don’t apply to them and others must not dare to hold them up for a nanosecond. Someone once told me the definition of a nanosecond is the time it takes for the lights to turn green and someone behind to toot you.
The horn. Use only while your vehicle is moving and you need to warn other road users of your presence. Never sound your horn aggressively. You MUST NOT use your horn
- while stationary on the road
- when driving in a built-up area between the hours of 11.30 pm and 7.00 am
except when another road user poses a danger.

I find the agressive use of car horns particularly aggravating when there’s a traffic jam.
