This is one sustained blast from a large truck air horn, lasting a little over two seconds, with a deep metallic honk that arrives at full strength and cuts off suddenly. It feels urgent and overblown at the same time, like a warning turned into a joke, which is why it makes a small moment feel suddenly huge. The sound comes from the compressed-air horns fitted to lorries and buses.
