noun
car horn; klaxon
Refers specifically to the electric horn of a car or other vehicle. The English-derived 'klaxon' is a less common gloss; 'car horn' is the everyday meaning.
後ろの車がクラクションを鳴らした。
The car behind me honked its horn.
クラクションの音で驚いた。
I was startled by the sound of a car horn.
A more general term for warning horn or whistle, used for trains, ships, and factories, not just cars.
Borrowed from English 'klaxon', originally a trademark for an electric horn. In modern Japanese, it refers to a car horn.
