What's the difference between a semi trailer and a full trailer

The terms "semi-trailer" and "full trailer" are commonly used in the context of commercial trucking and transportation. Here's the difference between the two:

Semi-Trailer:A semi-trailer, also known as an articulated trailer, is a type of trailer that is designed to be towed by a tractor-trailer or semi-truck. It is called a semi-trailer because it lacks a front axle and relies on a towing vehicle, commonly referred to as a tractor or truck, to provide support at the front. The front end of a semi-trailer has a kingpin that attaches to a fifth wheel coupling on the rear of the tractor, allowing it to pivot during turns.

Key features of a semi-trailer include:

1. It is typically longer and larger in size compared to full trailers.
2. The weight of the semi-trailer is partially supported by the tractor or truck towing it.
3. It has landing gear at the front that supports the trailer when it is not attached to a tractor.
4. Semi-trailers are commonly used in the transportation of goods and are a standard in the trucking industry.

Full Trailer:A full trailer, also known as a full-length trailer or tag-along trailer, is a type of trailer that is designed to be pulled by a vehicle, such as a pickup truck or a passenger car. Unlike a semi-trailer, a full trailer is a standalone unit that has its own front axle and is fully supported by the towing vehicle.

Key features of a full trailer include:

1. It is a complete unit with its own front axle and does not rely on a towing vehicle for support.
2. The weight of the full trailer is fully supported by its own axles.
3. Full trailers are generally smaller and lighter compared to semi-trailers.
4. They are commonly used for recreational purposes, such as hauling boats, small cargo, or personal items.

In summary, the main difference between a semi-trailer and a full trailer lies in their design, size, and the way they are supported. A semi-trailer is designed to be towed by a tractor or semi-truck, while a full trailer is a standalone unit that is pulled by a vehicle.
