What is the meaning of the code 903?

1. En route to hospital

2. Ambulance dispatched

3. Traffic collision

4. Aircraft accident

The correct answer is: Aircraft accident

The code 903 specifically refers to an aircraft accident within the context of radio communications used by emergency services, including law enforcement and fire departments. This code denotes a situation that requires immediate attention, as aircraft accidents can often involve significant hazards and require specialized response teams. Understanding the use of such codes helps responders quickly and accurately relay critical information during emergency scenarios. In contrast, codes such as "en route to hospital," "ambulance dispatched," and "traffic collision" pertain to other types of incidents that have their own specific codes, thereby providing structure to communication during emergencies. The distinction between these codes is essential for effective coordination among different agencies responding to various incidents.
