What Is the Height Clearance for a Semi Truck?

Semi-trucks, also known as 18-wheelers, are a common sight on highways and roads throughout the United States. These trucks are large and heavy, often weighing up to 80,000 pounds and measuring as long as 75 feet from bumper to bumper. So what is the height clearance for a semi-truck?

The maximum height clearance for a semi-truck is 13 feet and 6 inches. This includes not just the truck itself but also its cargo. However, some states have lower maximum height requirements due to low bridges or overhangs on certain roads.

For example, in California the maximum height for a semi-truck is 13 feet and 5 inches, while in Washington it’s 13 feet and 4 inches.

It’s important to note that many states require semi-trucks to have an even lower clearance when traveling on certain roads or bridges, so truck drivers must be aware of all restrictions in their area before setting out.

In addition to having a low overall clearance, semi-trucks also have other safety features designed to help prevent serious accidents. For example, many trucks now feature underride guards – metal bars that hang down between the back of the trailer and the ground – which can help prevent smaller vehicles from getting stuck underneath if there’s an accident.

Conclusion:

The maximum height clearance for a semi-truck is 13 feet and 6 inches including cargo. However, it is important to check local regulations as some states may have slightly lower requirements due to overhangs or bridges on certain roads. In addition, many trucks now feature underride guards which can help prevent smaller vehicles from getting stuck underneath if there’s an accident.
