No, they are belt driven. That's how they operate.
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.
Depending on the make, the average length of a tractor is 22 feet. A standard trailer is 53 feet. The combined average length of the vehicle is 70 feet.

A tractor trailer shut-off valve is a safety device used in the air brake system of a tractor-trailer. It allows the driver to isolate the trailer's air supply from the tractor, which can be essential for troubleshooting issues or for maintenance. By cutting off the air supply, the valve helps prevent accidental trailer brake engagement while the tractor is being serviced or when the trailer is disconnected. This enhances safety and ensures proper functioning of the braking system.
The average length of a standard tractor trailer is 70 feet in all, the trailer itself being 53 feet in length. Most flatbed trailers are 48 feet long.
Four to nine MPG, depending on a number of factors. It's pretty much the same with any tractor trailer.
