How Wide Is a Semi-truck?

When driving on the highway, it’s essential to be aware of the dimensions of heavy-duty trucks, including semi-trucks, dump trucks, and concrete trucks. These massive vehicles can take up a lot of space on the road, and if you’re not careful, you could end up in a severe accident. In this article, we’ll explore the dimensions of these types of trucks, so you can be better prepared when sharing the road with them.


Semi-Trucks: How Wide Are They?

Semi-trucks are among the largest vehicles on the road. They’re commonly used for transporting goods over long distances and can weigh up to 80,000 pounds when fully loaded. One crucial factor to consider when driving near a semi-truck is its width.

While the width of a semi-truck can vary depending on the model and make, the average width is about eight and a half feet. That’s nearly one foot wider than a standard passenger vehicle! It’s essential to be aware of this when driving near a semi-truck. Make sure to give them plenty of space, and never try to pass one on the shoulder of the road. If you need help sharing the road with a semi-truck safely, consult your local Department of Motor Vehicles (DMV) for more information.

Dump Trucks: How Big Are They?

A 10-wheeler dump truck is a heavy-duty vehicle used to haul large loads of materials such as dirt, gravel, and sand. The dump truck has a large bed that can be raised and lowered to facilitate loading and unloading. The dimensions of a 10-wheeler dump truck vary depending on the manufacturer. Still, they’re typically around 11 feet tall, 8 feet wide, and 29 feet long. The dump truck’s bed can also be raised to 23 feet, making it possible to haul large loads.

Concrete Trucks: How Tall Are They?

A concrete truck is a truck designed to transport concrete to construction sites. The most common type of concrete truck is the front-loading truck, which has a large concrete mixer drum that extends over the truck’s cab. These trucks are typically around 13 and a half feet tall. Smaller concrete trucks, often called mini mixers, have a much smaller drum that holds about 4-5 yards of concrete. These trucks are usually around 11 feet tall.

Concrete Trucks: How Far Can They Reach?

Most concrete trucks reach about 137 feet horizontally and 124 feet vertically. However, it’s always best to consult a ready-mix concrete delivery company to measure your needs accurately. The vertical reach is essential for taller buildings or construction sites. In contrast, the horizontal reach is ideal for getting concrete into tighter spaces.

Specialized trucks also have an even greater reach, which can be helpful for large construction projects. Whatever your project requires, there is likely a concrete truck that can meet your needs.

Concrete Chutes: How Far Do They Reach?

Pouring concrete can be messy, but using a concrete chute can make the process much easier. These long, funnel-shaped tubes attach to the back of a concrete truck and allow the concrete to be poured into a specific area without making too much of a mess. On average, a concrete chute can reach 18 feet, measured from the truck’s tires to the discharge point. Proper chute placement is critical to avoid pouring the concrete into the wrong location and creating a big mess that can cause delays on the job site.

Tri-axle Dump Trucks: How Big Are They?

Tri-axle dump trucks are larger than their smaller counterparts. They have a greater load capacity, making them ideal for heavy-duty use. These trucks typically range from 20-22 feet long. They can carry up to 37,650 kg, making them an excellent choice for hauling large amounts of material.

Freightliner Trucks: How Wide Are They?

The average truck in the United States is typically around 72 feet long, 8.5 feet wide, and 13.5 feet tall. Though the dimensions of specific models can vary slightly, all Freightliner trucks share the same width of 8.5 feet. This dimension is crucial because it determines the size of the truck’s load and the number of lanes it can occupy on a highway. A fully-loaded Freightliner truck can weigh up to 80,000 pounds and still stay within the legal limit for highway travel in most states.


Truck dimensions are an essential factor to consider when working in construction, transportation, or any industry that involves heavy hauling. Understanding the dimensions of concrete chutes, dump trucks, and Freightliner trucks can help you make informed decisions when selecting the appropriate vehicle for your needs. Consult with experts in the field, such as trucking companies, for additional information and guidance.
