How Do You Spell TRACTOR TRAILER?

1. A tractor-trailer, also known as a semi-truck or an articulated lorry, is a large vehicle primarily used for transporting goods over long distances. It consists of two main parts: a tractor unit, which is the front part, and a trailer unit, which is the rear part.

   The tractor unit, also referred to as the cab or the truck, contains the engine, driver's cabin, and all the necessary controls to operate the vehicle. It is equipped with a powerful engine to provide sufficient power and torque for pulling heavy loads. The driver's cabin provides a comfortable and functional space for the driver to operate the vehicle, including controls for steering, acceleration, braking, and communication systems.

   The trailer unit is a long rectangular container, typically without its own propulsion system, that is attached to the tractor unit. It is specifically designed to carry a wide range of goods and materials, and may come in various types such as flatbeds, refrigerated trailers, tankers, or enclosed cargos. The trailer often has multiple axles and wheels to distribute the weight evenly and improve stability. The connection between the tractor and the trailer is made through a fifth wheel coupling, allowing for articulation and movement between the two units.

   Overall, tractor-trailers are essential for the transportation of goods on a large scale, contributing significantly to the global economy and supply chain. Their size and capacity make them suitable for long-haul journeys, and they are commonly seen on highways and interstate roads.
