Commercial motor vehicles (CMVs) are large vehicles designed for transporting goods or passengers for business purposes. This category includes trucks, buses, and vans that exceed a certain weight limit, typically over 10,000 pounds. CMVs are essential for logistics and public transportation, playing a crucial role in the economy. These vehicles are subject to specific regulations and safety standards set by authorities like the Federal Motor Carrier Safety Administration (FMCSA) in the United States. Drivers of CMVs often require special licenses, such as a Commercial Driver's License (CDL), to ensure they are qualified to operate these larger and more complex vehicles safely.
