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. Semi trailers are also referred to as truck trailers and are typically listed under the Heading: Trailers-Truck in most phone directory yellow pages.
