What Is the Widest Semi Truck?

The widest semi truck is an important consideration for those who need to transport large items like furniture, construction materials, and more. Semi trucks are used in the transportation of goods across the globe and they come in a variety of sizes and shapes.

When it comes to transporting large items, having the widest semi truck can make all the difference.

Semi trucks are typically made with a single axle and a double-axle configuration. The single-axle configuration provides stability for smaller loads, while double-axle trucks can be used to carry larger loads due to their increased stability and weight capacity. Double-axle semi trucks are usually wider than single-axle models, allowing for more room in the cargo bay.

The width of a semi truck is determined by its frame size. This frame size determines how wide the truck will be including the cab, cargo area, and extra components like bumpers or side panels.

Generally speaking, the longer the frame size is, the wider the truck will be. The typical widths range from 102 inches to more than 116 inches.
