Which of the following is a correct use of your car’s horn?

Answer: B — To alert a driver who may not see you

The correct use of your car’s horn is to alert a driver who may not see you. This practice is essential for safety, especially in situations where visibility is limited or when another driver may be about to make a maneuver that could lead to a collision. Using the horn in this way helps to communicate your presence and prevent accidents, particularly in scenarios such as merging into traffic or navigating intersections. Using the horn as a means of communication to express frustration or anger, signal lane changes, or hurried pedestrians does not conform to recommended driving practices. These incorrect uses can contribute to road rage, distract other drivers, and create confusion. Safe and responsible use of the horn is aimed at enhancing safety and awareness on the road.
