What Is the Max Height of a Semi Truck?

Semi trucks are a common sight on the roads, hauling cargo from place to place. But what is the maximum height of a semi truck?

The answer depends on many factors such as the type of truck, the road it’s travelling on, and any regulations in place.

The most common type of semi truck is a tractor-trailer rig, which consists of a large tractor that tows one or more trailers behind it. This type of truck has a maximum height limit of 13.5 feet, or 4.1 meters.

This includes both the tractor and trailer combined. All other vehicles with an overall height above this limit must be equipped with an oversize load permit before they can travel on public roads.

On some highways and interstates in the US, there are larger vehicles known as “super-sized” trucks that may have a maximum height of up to 16 feet (4.9 meters). These trucks are usually used for transporting heavy cargo such as industrial equipment or construction materials, and they require special permits from state governments before they can travel on public roads.

Special Regulations in Place

In some states, there are additional regulations in place that may limit the maximum height of semi trucks even further. For example, California has implemented an overall vehicle height limit of 14 feet (4.3 meters) for all vehicles travelling on their highways and interstates. This includes both the tractor and trailer combined.

Conclusion

The maximum height of a semi truck depends on several factors such as type of truck, road it’s travelling on, and any regulations in place. The most common type is a tractor-trailer rig which has an overall maximum height limit of 13.5 feet (4.1 meters), although some states have additional regulations that may reduce this limit even further.
