What Is the Length of a Semi Truck and Trailer?

Tractor-trailers, or semi-trucks, are an essential part of the transportation industry. They move goods from one point to another and are an important part of modern life. But exactly how long are these behemoths?

The typical length of a semi-truck is about 70 feet, and when combined with the trailer it can range from 60 to 80 feet depending on the type of cargo being hauled. Semi-trucks come in various sizes depending on the application they are used for, so a semi-truck hauling a flatbed trailer may be shorter than one hauling a tanker trailer. The weight limit for a semi-truck is 80,000 pounds or 36,000 kilograms.

The length of a truck and trailer combination is regulated by the Department of Transportation (DOT) in each state. The DOT has enacted length regulations to ensure that semi-trucks can safely navigate highways without blocking traffic or causing dangerous situations. In most cases, trucks that exceed these limits will be subject to fines.

Semi-trailers

Semi-trailers can vary in length from 48 to 53 feet depending on its design and purpose. A 53 foot trailer is typically used for hauling general freight whereas 48 foot trailers are better suited for carrying heavy loads like steel coils or lumber.

Tanker Trailers

Tanker trailers are typically longer than other types of trailers due to their specialized design and purpose. Tanker trailers can range in length from 55 to over 100 feet depending on their capacity and function.

Tanker trailers also have additional safety features such as pressure relief valves and additional lighting.

Short Haul Trucks

Short haul trucks are usually shorter in length than other types of semi-trucks due to their limited range and payload capacity. Short haul trucks usually have a maximum length of around 65 feet when combined with the trailer.

Conclusion:

In conclusion, the average length of a semi truck and trailer combination is about 70 feet but can range anywhere between 60 – 80 feet depending on its size and purpose.
