What is it when the horn won't turn off?

When a car horn won't turn off, it typically indicates a malfunction in the horn circuit, often caused by a stuck horn relay, a faulty switch, or an electrical issue. This can lead to continuous honking, which can be annoying and may drain the vehicle's battery. It's advisable to inspect the horn system and address any issues promptly to prevent further damage or disturbances. If troubleshooting doesn't resolve the problem, consulting a mechanic may be necessary.
