A self-propelled ambulance vehicle is a type of emergency vehicle that is commonly used in airports to provide medical assistance to passengers and staff. These vehicles are equipped with medical supplies, equipment, and personnel to provide medical care in case of an emergency. The self-propelled feature allows the vehicle to navigate around the airport and reach the incident site quickly. Some self-propelled ambulance vehicles are designed with a built-in stretcher for transporting patients to medical facilities. These vehicles are an essential part of airport emergency services and help ensure the safety and well-being of everyone on the airport premises.
