Big Rig (type of truck)

A big rig is a large, heavy-duty truck typically used for transporting goods over long distances. It consists of two main parts: the tractor, which is the cab and engine where the driver sits, and the trailer, which carries the cargo. These trucks are built to haul large loads efficiently and safely on highways, often spanning hundreds or thousands of miles. They play a crucial role in logistics and supply chains, moving various products like food, furniture, and electronics across regions. Big rigs are also known as tractor-trailers, freightliners, or semi-trucks.
