Ten-codes, also called ten-signals, are abbreviations used to shorten common phrases in radio communications. Thus allowing for brevity and standardization of messages. They have been widely used by law enforcement, and in Citizens Band (CB) radio transmissions.
Ten-codes, especially "10-4" (meaning "understood") first reached public recognition in the mid- to late-1950s through the popular television series Highway Patrol, with Broderick Crawford. Crawford would reach into his patrol car to use the microphone to answer a call and precede his response with "10-4".
