What is a Signal 7 Police Code?
A Signal 7 police code is a radio communication code used by law enforcement agencies to convey specific information or instructions to other officers. The code is used to quickly and efficiently convey important information, such as a suspect’s location, a crime in progress, or a need for backup.
History of the Signal 7 Code
The Signal 7 code has its roots in the early days of radio communication in law enforcement. In the 1940s and 1950s, police departments began using Morse code to communicate over the radio. As radio technology improved, police departments transitioned to using phonetic codes to convey information.
