A tractor trailer is generally 13 to 14 feet tall, but this can vary depending on the type of trailer and the load it’s carrying. It is important to know the height of a tractor trailer for road safety, transport planning, and logistics management. Not all bridges and tunnels are built with the same height clearance. Therefore, if the height of a tractor trailer is greater than that of a bridge or tunnel, it can cause serious damage.
Similarly, businesses and logistics hubs often have height-restricted garages. A tractor trailer, which is a combination of a tractor (engine, driver’s cabin) and a trailer (carries cargo), is also important to avoid overloading. Trailers can be of varying types—flatbeds, box trailers, refrigerated trailers, and tankers.
It is also called a semi-trailer because it doesn’t have front wheels. It relies on the tractor for support at the front and is connected to it through a connection point called the kingpin.
