Ten-four is a cop code. It means good to go, all right, see ya there, the like. Good buddy was added on by truckers who pick up on jargon by listening to their scanners. So in ten four good buddy, it’s like one truck driver saying to another okay, or right, or whatever it is in the affirmative. Getting back to “good buddy", back in the 70’s when the CB craze was catching on, every wannabe had one. It was also a way a trucker knew whether the person he was speaking to on the radio was a fellow trucker or a poser. Using “good buddy" was a dead giveaway.
What is Good Buddy in 10 4 Good buddy?
Good buddy. In the 1970s, this was the stereotypical term for a friend or acquaintance on the CB airwaves. Now the term “buddy” can be used similarly to the term “good buddy”. Good numbers. Well wishes to a fellow driver. Buddy is most commonly used as an informal word for a friend.
WHO USES 10-4?
While still in some use, ten-codes, including 10-4, have been replaced by plain language in more and more police departments due to variation in what the codes mean. Truckers and other CB radio users still use ’em though.
But 10-4 has become a staple expression for saying “OK” in American pop culture, appearing, as we’ve seen, in everything from old-time TV shows to everyday conservations.
When did the Cops use 10 4 Good Buddy
In practice, most CB users only use a handful, and 10–4 is probably the most common. 10–20 is also common, meaning your location. ‘What’s your twenty?’ is a reference to this code. Another is 10–10, meaning “standby” ‘Hang ten’ is a reference to this code when you want someone to wait a few seconds while you do something.
The point of the 10 code is to convey a very precise meaning without ambiguity, especially under poor signal conditions, where a spoken instruction could be difficult to make out. I believe it originated with US police use, though the exact meaning assigned to codes varies: Police 10 Codes
CB usage also varies, with new codes being added and existing ones changed according to local customary use. However, very common ones like 10–4 don’t change.b The ‘good buddy’ part is just a customary greeting used on CB.
When and Why was the 10 4 introduced?
In the 1930s, radio technology was still relatively new and limited. For starters, there were limited police radio channels, so officers couldn’t stay on the line too long or else others wouldn’t be able to get through. The ten-codes were invented to communicate information quickly and clearly.
The use of the number 10 before all of the codes was another workaround. 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 10 was used as a placeholder to give the motor-generator time to speed up enough to hear the second part of the code. 4 was simply chosen to mean “acknowledgment” of a message (10-3 meant “stop transmitting” in case you wanted to know).
These handy codes were quickly adopted by others communicating via radio, such as CB (Citizen Band) radio enthusiasts and truckers.
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.
The expression 10-4 further spread into popular culture when it was featured in C. W. 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 song went number one on the charts in the US and abroad and was even made into a movie in 1978.

What is The Ten-Codes
The ten-codes or ten-signals are code words used as stand-ins for common phrases in radio communication. Charles Hopper, a communications director with the Illinois State Police, developed them in 1937 to combat the problem of the first syllables or words of transmission being cut off or misunderstood.
Preceding every code with “ten” gave the sometimes slow equipment time to warm up and improved the likelihood that a listener would understand the important part of a message. The codes also allowed for brevity and standardization in radio message traffic.
The codes were expanded by the Association of Public-Safety Communications Officials-International (APCO) in 1974 and were used by both law enforcement agencies and civilian CB radio users. Over time, differing meanings for the codes came about in different agencies and jurisdictions, undoing the codes’ usefulness as a concise and standardized system.
The problem came to a head in 2005 during rescue operations after Hurricane Katrina. After several instances of inter-agency communication problems, the United States Federal Emergency Management Agency (FEMA) discouraged the use of ten-codes and today the federal government recommends they be replaced with plain, everyday language. Here’s the official APCO list.
Code : Roger That
In the days of the telegraph, the Morse code letter R (dot-dash-dot) was sometimes used to indicate “received” or “message received/understood.” When radio voice communication began to replace telegraphs, Roger, the codeword assigned to the letter R in the Joint Army/Navy Phonetic Alphabet (the radio alphabet used by all branches of the United States military from 1941 to 1956), took on the same role.
Contrary to what Hollywood would have you think, Roger only means “the last transmission received/understood” and does not also mean or imply “I will comply.” Wilco (Will Comply) is the code used if the speaker intends to convey “message received and will comply.” Given that, the phrase Roger Wilco, which you so often hear in the movies, is redundant and not really used since Wilco alone covers all the bases and acknowledges receipt of a message and states intent to comply.’
Code : Mayday
Mayday is an international code word used to signal life-threatening emergencies. It was originated in 1923 by Frederick Stanley Mockford, a senior radio officer at London’s Croydon Airport. He was given the task of coming up with a unique and easily understandable emergency code word. Most of the air traffic at Croydon was either coming from or going to Le Bourget Airport in Paris, so Mockford chose mayday because of its similarity to the French maider (“come help me”).
Because it is an emergency signal, there are plenty of rules governing the use and format of a mayday call. A mayday call can only be made when life or craft is in imminent danger of death or destruction (and, as with fake 9-1-1 calls, fake mayday calls are considered serious crimes. In the U.S., making a fake distress call is a federal crime that can carry large fines and jail time), and once one is made, no other messages can be transmitted except to assist in the emergency.
The correct format for a Mayday call is:
“Mayday, Mayday, Mayday.” The call is always given three times in a row to keep it from being mistaken for a similar-sounding phrase, or to distinguish an actual distress signal from a message about a mayday call.
“This is ____.” The vessel name is repeated three times, followed by a call sign if available.
“Mayday. [vessel name].”
“My position is ____.” The position is given in latitude-longitude coordinates or bearing and distance from a fixed point.
“I am _____.” The type of emergency, e.g. fire or sinking.
“I require immediate assistance.”
“I have _____.” The number of people on board and their condition, as well as any other pertinent information, e.g. abandoning to life rafts.
Some radio instructors suggest the mnemonic MIPDANIO for learning mayday signal format: Mayday, Identify, Position, Distress, Assistance, Number of crew, Information, Over.
What is the Origin of 10 4 Good Buddy?
This phrase originates from the North American “CB” culture of the 1970s that was highly popularized by Hollywood films, commonly in road comedies like Cannonball Run and Smokey and the Bandit.
CB (Citizen’s Band) radios were widely used in the heavy trucking industry, which created a niche user community thus developing a then unique camaraderie akin to today’s online gaming community. True friendships are made where individuals may never meet in real life.
“Ten-four (10–4)” is borrowed from the ordered and disciplined police radio voice procedure. As a code, it denotes acknowledgment of a previous statement. “Good buddy” however is a very familiar and endearing term conjuring American southern hospitality. The confluence of the two statements creates a deliberately ironic expression that is at once officious and informal.
The Ten-codes (officially the Ten Signals) are used by American police departments for both clarity and brevity in radio communications. They were originally developed beginning in 1937, and have been both revised and extended several times since. Ten-four is a universal acknowledgment code (as in OK), going back to the original development of the code, and indicates both receipt and acknowledgment of the prior message. It is a combined “Rodger" and “Wilco".
With the advent of CB radio for civilian use, many of the 10 codes were adopted by CB users and later somewhat modified by popular usage. 10-4 retains its original meaning and usage, but its reverse, or 4-10, is now a request for acknowledgment.
“Good buddy" is basically a polite form of address that does not require the repeating of the “handle” or radio nickname of the person addressed. Please remember that CB is an open channel environment where several people may be on the channel simultaneously.
Therefore “10-4, good buddy" is the rough equivalent of saying “Rodger, Wilco, sir", and considerably more clear and concise over an open channel.
Translation: Channel Break, Channel 19 I-480, eastbound, Traffic Police at the eastern end of the Cuyahoga Valley bridge, acknowledge?
“10-4, good buddy. Shuttlecraft Galileo, into the sun, and backing down. You’re clean and green into the sunset.”
Translation: Rodger, sir. SG acknowledges. I’m approaching the trap, slowing as appropriate. There is nothing for you to worry about ahead on the westbound side.
“10-4, good buddy. (handle), out.”
Translation: Rodger, and thanks. This is (handle), over and out. The channel is now clear for other users.
