11-54 Police Code Meaning: Suspicious Vehicle

The 11-54 police code is used by law enforcement officers to refer to a suspicious vehicle.

Understanding codes like 11-54 is crucial for smooth communication between officers and dispatchers. These codes shorten communication time, eliminate confusion, and ensure rapid responses in emergency or uncertain scenarios.

History and Origin of Police Codes: Including the 11-54 Code

Police radio codes like 11-54 were first introduced between 1937 and 1940 by the Association of Public-Safety Communications Officials-International (APCO). Originally developed to improve clarity and speed over two-way radio systems, these codes reduced miscommunication and kept sensitive information brief and discreet.

The idea of brevity codes actually began earlier, in June 1935, when APCO proposed a set of Morse-code-based signals in The APCO Bulletin. These early communication techniques were inspired by the U.S. Navy’s procedures and later evolved into what we now know as Ten Codes and 11 Codes, including 11-54.

APCO formally expanded and standardized the codes in 1974, resulting in the widespread adoption of signals like 10-7 (Out of Service), 10-42 (Officer’s End of Tour), and of course, 11-54 for Suspicious Vehicle.
