While the average height of a tractor trailer is 13 feet 6 inches, the actual height can vary depending on several factors. One of the main factors is the type of trailer. Some trailers are taller, while others are shorter. The cargo being transported can also play a role in determining the height of the trailer. For example, if the cargo is tall, then the trailer will need to be taller to accommodate it. Another factor is the tires and suspension of the tractor and trailer. Different tire sizes and suspension systems can affect the height of the tractor trailer.
