A semi-trailer is equipped with legs that can be lowered to support it when it is unhooked from the tractor. When coupled together, the tractor and trailer combination is often referred to as a semi, 18-wheeler, big-rig, articulated lorry, or truck and trailer. The purpose of a semi-trailer is to carry freight. There are several types of semi-trailers including dry freight vans, refrigerated vans (reefers), flatbeds (standard, step-deck, lowboy, double drop, etc.) and tank trailers. Trailer sizes vary, but the most common sizes today are 53' or 48' in length and 102 or 96 in width.
