You should use your horn when:

Pedestrians cross without looking.
The traffic signal turns green but the vehicle in front doesn't move.
You get frustrated.
A vehicle is approaching in your lane in the opposite direction.
Explanation

Avoid using your horn unless it’s absolutely necessary to prevent a collision. For instance, use your horn-and flash your headlights-if a vehicle is drifting into your lane and heading toward you. This alerts the other driver and may help prevent a crash.
