Here are 5 of the best CB radios for semi trucks. Before diving in, let’s first understand the difference between Semi-trucks and normal trucks.

Semi Trucks Vs Normal Trucks


A semi-truck sometimes called a combination vehicle or articulated vehicle is a truck that has its own engine and is equipped to tow one or more cargo-bearing semi-trailers.

A semi-truck typically weighs over 10,000 pounds (without cargo and passengers). The length of these trucks ranges from 28 – 53 feet while their height ranges from 12.6 – 13.6 feet.

The width ranges from 8 – 12 feet. Semi-trucks are capable of hauling loads from 20,000 – 80,000 pounds. In the United States, semi-trucks are also referred to as 18-wheelers, semis, semi-trailers, semi-tractor-trailers, or big rigs.

Examples of semi-trucks that are commonly seen on roads include car hauler, lowboy, Conestoga, side kit trailer, and dry bulk. Others are dump, double drop, intermodal chassis, reefer, hopper-bottom, tanker, step decks, Stretch Removable Gooseneck, and single drop deck.

Normal Trucks

A normal truck also called a straight truck, is self-contained and has no trailer. This truck type comes with axles, containers, and a cab attached to the same structure.

In the US, these vehicles are also called box trucks, cube vans, cube trucks, and rolling toasters. These vehicles typically range in length from 10 – 26 feet, width from 8 – 12 feet, and height from 6 – 8 feet.

Straight trucks are generally used for hauling goods locally. Their most common cargo includes furniture, boxes, and appliances. They can haul goods that weigh from 12,500 – 33,000 pounds.

Some examples of straight trucks that are commonly seen on roads include garbage trucks, dumpster trucks, and pickup trucks.
