Which organization governs radio discipline and operations in the United States?

• A. NHTSA
• B. FAA
• C. FCC
• D. NIH

Answer: (C)

Radio discipline and operations in the United States are governed by the Federal Communications Commission. The FCC licenses and oversees the use of radio frequencies, sets technical rules for transmitters and emissions, assigns channels, and enforces rules to prevent interference. This framework covers public safety communications like police dispatch as well as other wireless services, providing clear, reliable, and lawful use of the spectrum. The other agencies listed don’t manage overall radio spectrum or operating rules: NHTSA focuses on vehicle safety, FAA on aviation, and NIH on health research. In public safety, you’ll often see Part 90 rules under FCC oversight for land mobile radio, which covers how agencies license and operate their radios to maintain discipline and interoperability.
