Despite the ubiquity of smartphones and other mobile devices, CB radios are still commonly used by truckers. In fact, many trucking companies require their drivers to have a CB radio, as it is an essential tool for communication and coordination. While CB radios may not be as flashy or technologically advanced as smartphones, they are incredibly reliable and offer a level of flexibility that is simply not possible with other devices. In addition, CB radios are much less expensive than smartphones, making them a more practical choice for many truckers.
