There are other types of ambulance, with the most common being the Patient Transport Service. These vehicles are not usually (although there are exceptions) equipped with life-support equipment, and are usually crewed by staff with fewer qualifications than the crew of emergency ambulances. Their purpose is simply to transport patients to, from or between places of treatment. In most countries, these are not equipped with flashing lights or sirens. In some jurisdictions there is a modified form of the ambulance used, that only carries one member of ambulance crew to the scene to provide care, but is not used to transport the patient. Such vehicles are called Fly Car. In these cases a patient who requires transportation to hospital will require a patient-carrying ambulance to attend in addition to the fast responder.
