We have actually all seen those huge items of rubber from semi truck tires on the freeway.

They are referred to as alligators. Roadway kill is an usual site on numerous roads, as well as truck drivers describe it as roadway pizza. Flat bed trailers are typically referred to as skateboards. Tractor trailers are frequently described as a box. If you see a vehicle relocating without a trailer affixed to it, truckers call this bobtailing. While it conserves them of fuel mileage, it is a bumpy roadway without that trailer on the back to help smooth points out.
