Most trailers are semi trailers. You're probably asking the difference between a semi trailer and a full trailer. A semi trailer is not wholly self supporting, and weight is distributed both the trailer axles, and to the tow vehicle. A full trailer supports its own weight fully.
The difference between freight and package is the size of the container. Freight refers to the size of the entire shipment, such as a semi trailer's contents. Package is just one part of the entire shipment, like one pallet or box on the semi trailer.
Trailer is way more bigger than a semi-trailer. Common misconception between a trailer and a semi-trailer. Technically, a trailer has wheels in front and rear and is hitched to a pulling vehicle (car,truck,etc.) A semi- trailer only has wheels in the rear and is hitched to a pulling vehicle (car,truck,etc.)
As evenly as possible between the drive and trailer axles.
The "tractor" is the vehicle which actually powers the combination. A semi-trailer is any trailer in which the weight of the trailer (and the payload) is shared between the trailer's axles and the axles of either a dolly or the towing unit (in contrast, a full trailer supports all of its own weight).
There isn't one. So long as the weights on each axle/set of axles are legal, that's all Barney cares about.
The one difference between trailer and trailor is that trailor is not even a word. However, trailer is. A trailer is what you would call a mobile home.
You call it a semi because it pulls a semi trailer.A semi is a type of trailer. A semi-trailer, as opposed to a full trailer, means it only has axles at the rear of the trailer and a full trailer has axles at the front and rear of the trailer. We call these in the UK "drags", as in wagon and drag, where the wagon that pulls the drag can carry a load on its own, whereas the semi-trailer truck, or tractor unit cannot carry anything without a trailer.
Most semi trailers have 8 wheels, some have 12. The tractors almost all have 10 wheels but some of them have 14.
