How Big Is the Biggest Semi-Truck?

Semi-trucks, also known as semi-trailers or articulated lorries, are the largest vehicles on the road. They are used by businesses to transport goods across long distances, and they can be seen on highways all around the world. But just how big is the biggest semi-truck?

The answer depends on a few factors, including the type of truck and its purpose. For example, a fuel tanker is typically much larger than a flatbed truck that carries pallets of goods. The size of the trailer will also affect the overall dimensions of the semi-truck.

Generally speaking, the longest semi-trucks measure up to 53 feet long and 13 feet 6 inches high. These measurements are taken from outside the trailer and include any external components such as bumpers or mirrors. The width of a standard semi-truck is 8 feet 6 inches.

Semi-Trucks with Special Permits

In some countries, it’s possible to get special permits that allow you to drive a semi-truck with longer dimensions than usual. For example, in Europe some countries allow for special trailers up to 60 feet long and 14 feet 6 inches high. In the U.S., there are permits available for trailers that measure up to 53 feet 10 inches long and 14 feet 5 inches high.

Conclusion

The biggest semi-trucks on public roads have an overall length of 53 feet and a maximum height of 13 feet 6 inches. However, drivers may obtain special permits that allow them to operate larger trucks in certain areas.
