A semi-truck, also known as a tractor-trailer or big rig, is a large commercial vehicle used for transporting goods over long distances. It consists of a cab, where the driver sits, and a trailer that is attached to the cab.
The cab of a semi-truck is designed to accommodate the driver and any passengers, with a sleeping area, air conditioning, and other amenities. The trailer is typically made of metal and can be either enclosed or open.
Semi-trucks are used for transporting a wide range of goods, from raw materials to finished products, across various industries, including manufacturing, retail, and construction. They are known for their capacity to carry large loads, and they are often used to transport goods over long distances due to their fuel efficiency and durability.
Semi-trucks require a special license to operate, and drivers must undergo extensive training to learn how to handle these large vehicles safely. They also require regular maintenance to ensure that they are in good working condition and can operate safely on the road.
