Citizens Band radio

Citizens Band, or CB, radio is a short-distance radio system that does not require a license and can be used by individuals or businesses for various communication purposes. CB radio in the U.S. was first introduced for personal use in the 1940s, and became especially popular in the 1970s when equipment costs dropped significantly. The system was widely used among small businesses and truckers. Although new technology in recent years brought about a decline in CB usage, truck drivers trill utilize it to share communication regarding service stations, fuel prices, road conditions, or speed traps.
