McCall’s 1975 song “Convoy,” where he uses trucker CB radio slang like breaker one-nine (a radio channel used by truckers) and 10-4. The expression 10-4 further spread into popular culture when it was featured in C. Helping to popularize 10-4 in the mainstream was the 1950s TV crime drama Highway Patrol, starring Broderick Crawford, known for starting his conversations on his radio with 10-4. Oh, the ’50s. These handy codes were quickly adopted by others communicating via radio, such as CB (Citizen Band) radio enthusiasts and truckers. 4 was simply chosen to mean “acknowledgement” of a message ( 10-3 meant “stop transmitting” in case you wanted to know). The 10 was used as a placeholder to give the motor-generator time to speed up enough to hear the second part of the code. It took a split second for the motor-generator in the radios to warm up, and so the first syllables of a radio transmission were often lost. The use of the number 10 before all of the codes was another workaround. The ten-codes were invented to communicate information quickly and clearly.
