Editing Ten-code (section)

===In popular culture===
Ten-codes, especially "10-4" (meaning "understood") first reached public recognition in the mid- to late-1950s through the television series ''[[Highway Patrol (U.S. TV series)|Highway Patrol]]'', with [[Broderick Crawford]].{{citation needed|date=April 2020}}

Ten-codes were adapted for use by [[Citizens band radio|CB radio]] enthusiasts. [[C. W. McCall]]'s hit song "[[Convoy (song)|Convoy]]" (1975), depicting conversation among CB-communicating [[trucker]]s, put phrases like "10-4" and "what's your twenty?" (10-20 for "where are you?") into common use in American English.{{citation needed|date=April 2020}}

The movie ''[[Convoy (1978 film)|Convoy]]'' (1978), loosely based on McCall's song, further entrenched ten-codes in casual conversation, as did the movie ''[[Smokey and the Bandit]].

The New Zealand [[reality television]] show ''[[Ten 7 Aotearoa]]'' (formerly ''Police Ten 7'') takes its name from the New Zealand Police ten-code 10-7, which means "Unit has arrived at job".<ref>{{Cite web |last=Admin |first=Blow on the Pie |title=NATIONAL RADIO CODES / POLICE {{!}} BlowonthePie - For New Zealand Scanner Codes and more |url=https://blowonthepie.co.nz/emergency-codes/national-radio-codes-police/ |access-date=2025-03-02 |language=en-US}}</ref><ref>{{Cite web |last=Screen |first=NZ On |title=Police Ten 7 {{!}} Series {{!}} Television {{!}} NZ On Screen |url=https://www.nzonscreen.com/title/police-ten-7-2002/series#:~:text=Taking%20its%20name%20from%20police,began%20presenting%20in%20September%202015. |access-date=2025-03-02 |website=www.nzonscreen.com |language=en}}</ref>
