When should you use your horn?

To communicate with other drivers
To alert other drivers you are near
To warn other drivers of danger
All of the above

The correct answer is: All of the above

When driving, you should use your horn to communicate with other drivers, alert drivers of your nearby presence, and warn other drivers of potential danger on the road. While some may believe they can only use their horn in a dangerous situation, it is also important to use it as a means of communication with other drivers on the road. In addition, you should always use your horn to inform others that you are nearby to prevent collisions or accidents from occurring. Therefore, all of the above options are correct and should be considered when using your horn while driving.
