What Is It Called a Semi Truck?

A semi truck, also known as a semi-trailer truck, tractor-trailer, or big rig, is a large road vehicle that typically consists of an engine cab and a flatbed trailer. The semi truck is used to haul large loads over long distances throughout the United States and Canada. Semi trucks are used to transport a wide variety of items, including agricultural products, construction materials, manufactured goods, and other commodities.

Semi trucks are typically powered by diesel engines and are capable of carrying up to 80,000 pounds of cargo. They can be loaded or unloaded using special loading ramps or mechanical lift gates. Semi trucks vary in size depending on the type of cargo they are hauling; some rigs are as long as 53 feet while others may be upwards of 90 feet.

Semi trucks have several components that make them well-suited for hauling large loads over long distances. The drive axles provide stability and traction on the road while the fifth wheel coupling allows for easy connection between the cab and trailer. The brakes in semi trucks are designed for maximum stopping power and reliability.

In addition to their use in the commercial transportation industry, semi trucks can also be found at many auto racing events such as NASCAR races. These vehicles have been customized with powerful engines and aerodynamic designs to achieve higher speeds on race tracks.
