What should the horn NOT be used to express?

The horn should not be used to express anger because its primary purpose is to ensure safety on the road by alerting other drivers or pedestrians of your presence, not to convey negative emotions. Using the horn in a way that expresses anger can create a hostile driving environment and may escalate situations unnecessarily. Rather than improving safety, it can provoke aggressive responses from other drivers, leading to dangerous scenarios.

In contrast, using the horn to show happiness, excitement, or surprise is generally more acceptable in lighthearted interactions and may not have the same potential for escalating conflict. However, it’s essential to remember that the primary function of the horn is safety, so it should be used judiciously and primarily for warning purposes.
