True or false: A vehicle's horn should be primarily used to indicate frustration with other drivers.

The correct response is that it is false to say a vehicle's horn should be primarily used to indicate frustration with other drivers. The primary purpose of a vehicle's horn is to alert other road users to potential hazards or to signal your presence to avoid collisions. Using the horn out of frustration can lead to unsafe driving behaviors and escalated road rage among drivers. It's important to use the horn judiciously, primarily to ensure safety rather than to express anger or impatience. This aligns with traffic laws and promotes a safer road environment for everyone.
