Semi-trucks, also known as 18-wheelers, are the heavyweight champions of the road. They transport goods across the country and make up a significant portion of the trucks used on highways.
While they come in different sizes and configurations, they all share one common characteristic: they are large. One aspect of a semi-truck’s size that is often overlooked is its width. On average, how wide is a semi-truck?
The average width of a semi-truck is about 8.5 feet (2.6 meters). This measurement does not include side mirrors or any other external features like extra lights or antennae, which can add up to an additional foot (0.3 meters) or more to the total width of the truck. There are some exceptions to this rule; for instance, some flatbed trailers can be as wide as 11 feet (3.4 meters), while other specialty trailers may be even wider.
The width of a semi-truck plays an important role in how it navigates roads and highways. Because these trucks take up so much space on the road, they must stay within certain limits when driving around curves and through tunnels or bridges with limited clearance.
An important point to remember
When considering the width of a semi-truck it is important to remember that this measurement does not account for any external features such as side mirrors or extra lights that may add additional inches or even feet to its total width.
Conclusion
Overall, the average width of a semi-truck is 8. However, depending on the trailer configuration and any extra accessories attached to it this number can vary significantly.
