Why is it recommended to limit the use of your horn?

Limiting the use of your horn is important primarily because it can startle other drivers. Horns are loud and can be a sudden and unexpected sound, which may cause confusion or panic for other road users. When a driver is startled, their reaction may not be predictable, leading to potential accidents. The horn should be used sparingly and only in situations where it is necessary to alert others to your presence or to avoid a collision, ensuring that its use is effective and does not create unnecessary chaos on the road.

While the other options might have some points worth considering, they do not encapsulate the primary reason for limiting horn usage as effectively as the correct choice does. For example, while using too much air pressure to honk could theoretically impact your braking system in certain vehicles, this is not a common concern for most drivers; hence, it is a less pressing reason. Distracting passengers might occur, but the primary focus for safety should be on other drivers. Finally, while excessive honking can feel pointless in some situations, there are definitely times when using the horn is necessary for safety.
