What is a semi-trailer
A semi-trailer is a functional part of a tractor-trailer combination.
Any type of semi-trailer, such as a reefer, dry van, or a flat bed, can be attached or detached from a tractor.
When it is detached, it cannot move because a semi-trailer doesn’t have an engine. So, to move it needs to be connected to a tractor.
This is the main way how they function. Semi-trailers are loaded, picked up by a semi-truck, and they are on the way to delivery.
