To get the answer, you need to weigh your tractor trailer empty. When you get that weight, Lets talk numbers, this is wrong but it is a big example. If your tractor trailer is 35,000 pounds empty. Means you can haul about 45,000, as long as you are not overweight on your three axles. Steer, Rear, and trailer axles. 12/34/34.
around 44,000 pounds, legally, in the US.
It depends on the commercial vehicle, how it's licensed, the state it's running in, and a lot of other things, but a tractor-trailer combination with tandem axles on the tractor and the trailer can generally carry 80,000 pounds--12,000 on the front axle and 34,000 on the tractor and trailer tandems.

Tractor trailor parts can be found at your local John Deere store. Other stores that carry tractor trailer parts include TSC (which is a feed store).
The weight that can be carried in a semi trailer legally varies. It depends on how much the tractor pulling the trailer weighs. The maximum weight of the total unit, truck and trailer is limited at 80,000 lbs without getting special permits. For a heavy tractor, the trailer would have to be loaded with less weight than a trailer pulled with a light tractor. It's not uncommon for a trailer to comfortably carry 45,000 with most over the road tractors. Some trailers can be loaded heavier as long as the don't exceed the maximum. Also, I should mention, axle weight will affect how much can be loaded also. only 34,000 can be loaded on the trailer and tractor rear axles. This means that the weight on the trailers must be properly distributed.
Not individually, but the vehicle they drive must be insured.
Around $60,000, and unless you work for a company you can't buy a separate trailer. $135,000 for a fullsize tractor, $72,000 for a reefer trailer.
A typical tractor trailer unit, with a total of five axles, can typically carry between 23 and 25 tons legally, dependent on the tare weight of the tractor and trailer. The legal interstate gross weight rating for such a setup is 80,000 lbs.
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.
Depends on the truck and configuration (e.g, tandem axle dump, tractor-trailer end dump, etc.).
Four to nine MPG, depending on a number of factors. It's pretty much the same with any tractor trailer.
