Ever wondered how your car horn actually works?
Your car horn may seem simple, but it plays an important role in road safety when used correctly.
Most car horns work using an electrical circuit. When you press the horn, it completes the circuit and sends power to the horn unit. This causes a small metal diaphragm inside to vibrate quickly, creating the sound you hear.
A horn should be used to alert other road users to your presence, especially if there is a safety concern.
It should not be used out of frustration, impatience, or to hurry someone along.
Learning how your car works, even in small ways, can help you become a more aware and responsible driver.
