True or false: An auxiliary horn switch is acceptable if the horn is located on the steering wheel.

An auxiliary horn switch is not acceptable if the horn is located on the steering wheel. The reason for this is rooted in safety and operational standards for vehicles. The primary horn must be easily activated by the driver without requiring additional switches or controls that could distract from driving or complicate usage in emergency situations.

Since the standard and expected design is for the horn to be directly accessible through a control integrated into the steering wheel, any auxiliary system would not meet safety regulations that ensure consistent and immediate access to the horn. Thus, having an auxiliary switch would not align with requirements, making the statement false.

This understanding emphasizes the importance of consistent and straightforward vehicle designs to maintain driver control and safety on the road, highlighting why the existence of an auxiliary horn switch in this context is not permissible.
