Truck trailers are a necessary tool for logistics and transportation, but there are several synonym options to describe this useful item. One of the most common alternatives for truck trailers is semitrailers, which are usually attached to a truck cab. Another great option would be a tractor-trailer, due to the fact that the trailer is pulled by a tractor unit, often driven by a professional driver. A more technical term for truck trailers is articulated lorry, which is British slang and refers to any type of trailer or semitrailer attached to a truck cab. Flatbed trailers, container trailers, and dump trailers are also other synonyms that could be used to describe more specific types of truck trailers.
