A vehicle with 18 wheels is commonly known as a "semi-truck" or "tractor-trailer."
The prefix "semi-" means "half", and the standard tractor-trailer articulated vehicle is called a "semi" because of the trailers they pull. A "full" trailer has wheels in the front and back, like a railway car, and connects to the tractor from the front. A "semi-trailer" (or, essentially, "half-trailer") only has wheels in the back, and the front sits over the back wheels of the tractor pulling it.
Safety guards?? The rear bumper must be no more than 30 inches from the ground. The requirement does not apply to pole trailers, pulpwood trailers, low chassis vehicles, special purpose vehicles, or wheels back vehicles.
