A tractor trailer, also known as an 2-wheeler or semi-truck, is a large vehicle used for transporting goods over long distances. It consists of two main parts: the tractor, which is the front part with the engine and driver’s cab, and the trailer, which is the large container used for carrying cargo. The tractor is responsible for pulling the trailer and is usually equipped with powerful engines to handle heavy loads. Tractor trailers are commonly seen on highways and are an essential part of the freight and logistics industry. They can carry a wide variety of goods, from food and clothing to machinery and building materials. These vehicles are designed to be sturdy and reliable, with features like large wheels, strong suspension systems, and advanced braking for safety. Tractor trailers play a crucial role in transporting goods across the country and are key to keeping supply chains running smoothly.
