Ambulances are generally considered emergency vehicles authorized to be equipped with emergency lights and sirens. Generally, vehicles count as an ambulance if they can transport patients. However, it varies by jurisdiction as to whether a non-emergency patient transport vehicle (also called an ambulette) is counted as an ambulance. 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. Conversely, EMS agencies may also have nontransporting EMS vehicles that cannot transport patients. (Full article...)
