Klakson is the Indonesian word for a vehicle horn, and this clip captures the sound of a car horn used on roads around the world. Because the sound needs no translation, it has travelled on soundboards and in short videos, where it is reused for traffic jokes, driving fails and sudden interruptions. It sits alongside other loud meme horns, such as the air horn, but its shorter, sharper blast makes it easier to drop into a beat. Its simplicity is why it remains popular: anyone instantly knows what it means, whether the scene is a street or a cartoon-style edit.
