What phenomenon can occur when many cellular 911 calls arrive for the same incident, affecting operations?

• A. Automatic prioritization
• B. Immediate dispatch of all units
• C. Redirection
• D. Overload

Answer: (D)

When many 911 calls come in about the same incident, the communications system can become saturated. There are only so many trunks, lines, and radio channels available, and once demand exceeds that capacity, calls pile up, hold times rise, and dispatchers may not receive information or allocate resources as quickly. This state of excess demand on the system is called overload, where operations are degraded because the network and consoles can’t process all the traffic efficiently. This isn’t about a policy or a planned action; it’s the real-world consequence of too many simultaneous requests for help. It’s the overload that explains why response times can slow and why coordination becomes more difficult.
