Using your horn is primarily intended to alert others to your presence or to warn them of potential danger. When coming out of a dark alley, this is particularly important, as pedestrians, cyclists, or other vehicles may not be aware of your approach. The horn serves as a crucial safety measure that can prevent accidents by notifying others that a vehicle is emerging from a place where visibility may be limited.

In contrast, the other scenarios do not typically require the use of a horn for safety. Merging onto a highway is usually accomplished by signaling with turn indicators rather than using a horn, as other drivers should be aware of merging traffic. Passing another vehicle should be done safely and with clear communication through signals rather than horn use. Finally, when stopped at a red light, there isn't a need to use the horn unless there is a situation where the car in front is not moving when it should. Overall, the use of the horn should be reserved for situations where caution and alertness are especially necessary.
