What button should be pressed on the farebox for a free ride?

Pressing the button designated for a free ride on the farebox is an important protocol for bus operators to ensure that passengers who qualify for free travel are documented properly. The correct choice indicates that in the farebox system, the specific button associated with free rides is set to the first button. This function allows operators to process the fare accurately without charging passengers who might qualify for free transportation, such as seniors, individuals with disabilities, or children, depending on the rules set by the transit authority.

The other buttons would be associated with different fare amounts or ticket types, which do not apply in the context of providing a free ride. Thus, selecting the appropriate button is crucial in maintaining proper fare collection and adhering to transit policies. Knowing which button to press helps ensure that the system operates smoothly and that all riders are treated fairly according to the rules of fare payment.
