Which of these is a proper use of your vehicle's horn?
Correct answer: To warn a driver or a pedestrian of a possible danger
Why
Missouri law requires every vehicle to have a working horn loud enough to warn other road users and pedestrians, and it bans using the horn for unnecessary noise. Needless honking can distract other drivers and even cause a crash. One warning use from the guide: if a vehicle comes at you head-on in your lane, slow down, move to the right, and sound your horn.
