The horn is operated by pressing the centre boss on the steering wheel.

It should make a loud noise.

As with many of the other items on the car, a functioning horn is a legal requirement. Perhaps more important is the fact that it can be a lifesaver in an emergency situation.

Given the importance of the horn, it is essential that it is checked from time to time to make sure that it is functioning correctly.

The operation of the horn is obviously easy to check, however, you should be aware of the legal issues.
