The full trailer is a type of trailer that has front and rear axles. It is fixed to the tractor unit, which means a full trailer cannot be separated. A drawbar for pulling or towing is also often seen on a full trailer. The semi trailer, however, is different from a full trailer in that it doesn’t have a front axle. People say that a semi trailer is the union of a truck and a trailer. It can be easily and flexibly detached from the truck.

The turning circle of semi trailer is smaller than a full trailer. Besides, semi trailer has longer cargo bed than full trailers, so the former is able to load more goods.

The bad news is a semi trailer is more likely to tip over because the center of gravity of it is higher than the full trailer. And people tend to cost more to maintain the semi trailer.
