What Is the Overall Length of a Semi Truck?

Semi trucks, also known as 18-wheelers or big rigs, are the largest vehicles on the road. They are typically used for long-distance freight transport and require special licensing to operate.

Most semi trucks have a length of 40 to 53 feet, with a maximum legal length of 75 feet. This includes the truck’s cab and trailer, as well as any additional cargo on the trailer.

The overall length of a semi truck will depend on several factors, including the type of cab and trailer being used, as well as the cargo being transported. The most common type of semi truck is a conventional tractor-trailer combination with a box-shaped trailer attached to a tractor unit. This combination usually ranges in length from 40 to 53 feet.

Semi trucks can also be configured in different ways depending on their cargo needs. A flatbed truck is designed to carry large items such as construction materials and machinery, while a tanker truck is used to transport liquids such as fuel or chemicals. These types of trucks can range in length from 40 to 70 feet depending on their cargo capacity.

In addition to conventional tractor-trailer combinations, some states allow for longer trailers that are known as “long doubles” or “turnpike doubles”. These trailers can be up to 90 feet in length and are typically used for long distance transportation over highways.

Conclusion:

Overall, the length of a semi truck can range from 40 to 90 feet depending on the type of cab and trailer being used, as well as any additional cargo that is transported. Long doubles are allowed in some states and can reach up to 90 feet in total length.
