What color is the spring park brake control valve typically found on the dashboard?

The spring park brake control valve is typically identified by its yellow color on the dashboard. This standardization helps drivers quickly recognize the park brake control, ensuring they can operate the vehicle safely and efficiently. The use of a specific color, such as yellow, is part of industry conventions to provide consistency across different vehicles and enhance safety by preventing confusion.

Recognizing these color codes is essential for proper vehicle operation, as they convey important information about the various functions of controls within the cab. The yellow color is a visual cue that alerts the driver to engage or disengage the spring park brake, which is crucial when the vehicle is stationary or parked to prevent it from rolling.
