A CB radio, otherwise known as a Citizens Band radio, is a classic piece of technology that provides a two-way communication system. Some people keep one at home or in a vehicle as a way to prepare for severe weather events and natural disasters that could affect cell service or for roadside incidents.
CB radios access a selection of channels all within a meter band set aside by the Federal Communications Commission (FCC) for personal and professional communications. Since CB radios do not require a license to operate, they are an accessible option for many radio hobbyists.
CB became popular during the 1970s and 80s, and the amount of traffic on CB stations increased dramatically, prompting some professional users—like electricians and plumbers—to move to VHF. Truck drivers, however, still use CB radio to learn about roadside incidents and road construction. Channel 19 is the unofficial “travelers’ channel”, making it a perk to have a CB radio in your car.
