How are the air horns activated?

The activation of air horns in fire apparatus is typically designed for efficiency and accessibility. The correct answer highlights the dual options available for activation: a switch on the steering wheel and a manual pull cord located overhead on the officer's side. This allows the driver to maintain control of the vehicle while also having the ability to signal using the air horn quickly and effectively.

The steering wheel switch facilitates easy activation with minimal distraction, enabling the driver to focus on the road while also being able to alert others to the presence of the fire apparatus. In addition, having a manual pull cord overhead offers an alternative method for activating the air horn, which can be especially useful if the driver's hands are otherwise occupied or if immediate access to the steering wheel is compromised.

The integration of multiple activation methods ensures flexibility and ensures that air horns can be activated in various scenarios, thereby enhancing safety and communication during responses.
