In what scenario is a lack of heat in a bus not considered a valid reason for removal from service?

A lack of heat in a bus is not considered a valid reason for removal from service when the bus is at 45 degrees. This temperature is generally accepted as a threshold where it is still comfortable for passengers and safety protocols regarding heating may allow the bus to continue operating despite not providing additional heat.

In many transit organizations, policies dictate that a temperature of around 50 degrees or above is typically acceptable for continued service, as it indicates a level of comfort. Therefore, while lower temperatures may prompt concerns about heating performance, at 45 degrees, the situation is generally regarded as manageable, particularly if passengers can be adequately accommodated with layers of clothing or by other means.

On the other hand, scenarios cited with temperatures below 40 degrees or above 50 degrees have different implications: below 40 degrees often necessitates heat for passenger safety and comfort, while exceeding 65 degrees is unlikely to require heating at all, making those situations different from the one at 45 degrees.
