The Truck Manufacturing industry is comprised of companies that manufacture medium- and heavy-duty trucks, such as semi-trucks, dump trucks, and other commercial vehicles. These companies design, engineer, and assemble the trucks, as well as provide aftermarket services such as maintenance and repairs. The industry is highly competitive, with companies competing for market share and customers. The industry is also heavily regulated, with government agencies setting safety and emissions standards. The industry is expected to grow in the coming years, driven by increased demand for commercial vehicles and the need for more efficient and environmentally friendly trucks.
