10-4 meaning is a phrase that has its roots in the CB radio culture of the 1970s, and it has since become a part of everyday language. “10-4” is a code word that was used by truck drivers and other professionals to communicate over long distances, and it has since been adopted by a wide range of people.
The phrase’s origins lie in the “10-codes” system, which was developed by the United States military and adopted by law enforcement agencies. The system uses a series of two-digit codes to represent common phrases, making communication more efficient and concise.
In this system, “10-4” means “received” or “understood,” and it quickly gained popularity among CB radio users.
