What type of alarms should bus operators prioritize?

Bus operators should prioritize silent alarms because these alarms are designed to alert personnel discreetly, allowing them to respond quickly without creating panic among passengers or contributing to an unsafe situation. Silent alarms are often linked to incidents that require immediate attention, such as emergencies or security threats, where a quick and quiet response is crucial for safety.

The other types of alarms serve different purposes. Routine alarms might be relevant for everyday operational issues but do not necessarily require immediate action or involve safety concerns. Maintenance alarms are important for ensuring the bus is in good working order, but they are typically not urgent in nature. Notice alarms may provide information but are less critical than silent alarms in urgent situations, meaning that bus operators must focus on silent alarms to ensure the safety and security of everyone on board.
