When should you use your horn?

To alert other drivers
When an emergency vehicle is approaching
To communicate your position
When you are in a hurry

The correct answer is: To alert other drivers

Using the horn to alert other drivers of your presence or to signal a potential danger is the most appropriate and common use. Option B is also a correct use, but it is limited to situations when an emergency vehicle is approaching and not always necessary. Option C may be useful in certain situations, such as when you need to communicate with another driver in a loud environment, but it should not be the primary use of the horn. Option D is incorrect because using the horn when in a hurry is unnecessary and can be seen as a form of aggressive driving.
