semi truck, or semi tractor trailer, and 18 wheeler.
Big truck, semi, 18 wheeler.
Semi Truck oer 18 Wheeler (Eighteen Wheeler)
Start by dropping your trailer. You will notice there are wheels on only one end. A trailer like that is a "semitrailer." A "full trailer" has wheels at both ends. The official name is a "tractor-semitrailer," shortened to "semi."
Any vehicle towing a trailer or other vehicle is, in essence, a tractor. If the dump truck is towing another vehicle (trailer, etc.), then it is a truck tractor. If it isn't, then it's just a straight truck.
The tractor weighs 20,000 pounds, the trailer weighs whatever it weighs, and the maximum weight of a loaded tractor trailer with one trailer is 80,000 pounds.

I would have to say no. I have a tractor that is insured the only thing that is insured is just that the tractor (fire theft etc). Although You can get your trailer insured just as you can an ATV horse trailer car truck if you had a policy for it. your tractor insurance will not help with the trailer.
The first major difference is the trailer, which turns on a pivot point. Another major difference is the blind spot. In a car, you can look out the rear window at things directly behind you - not so with a tractor-trailer.
Depends on what type of tractor and trailer you had in mind. For a farm tractor pulling a trailer, it's usually a pintle on the tractor which is run through a clevice on the trailer. For road going vehicles, the fifth wheel trailers are often used, where a trailer kingpin will be inserted and locked into a fifth wheel on the vehicle. In the case of an 18 wheeler, air lines will connect from the tractor to the trailer to operate the trailer's air brake system.
