CB Radios

Drivers take advantage of CB radios to help them find an alternate route in a traffic jam, warn them of blocked roads ahead, provide real-time weather reports and severe weather warnings, provide information about police activities, and call for assistance after a mechanical breakdown or medical emergency.

Citizens band radio (CB radio) is a land mobile radio system, a system allowing short-distance one-to-many bidirectional voice communication among individuals, using two-way radios operating near 27 MHz (or the 11-m wavelength) in the high frequency or shortwave band.
