How many hours of service must be provided under each ambulance license?

The correct answer regarding the hours of service that must be provided under each ambulance license is 24 hours, with the condition that this requirement does not apply if the ambulance does not respond to calls from public agencies. This stipulation recognizes that ambulances that are inactive or not in service for public calls have different operational requirements and thus do not need to meet the standard service hours. This flexibility allows ambulance services to adapt to the particular needs of their operational environment while ensuring that they are available for public health emergencies.

The other choices represent different hour intervals that are not aligned with the regulatory requirements for ambulance services. The choice of 12 hours does not meet the minimum threshold typically set for operational readiness in emergency services. Likewise, 36 hours and 48 hours exceed what is usually mandated, reflecting a potential misunderstanding of the balanced needs for readiness and capability in providing emergency medical services.
