Colorado CDL Practice Test

A Class B vehicle is defined as a heavy straight vehicle that has a gross vehicle weight rating (GVWR) of 26,001 pounds or more, or is designed to transport a certain number of passengers. Heavy straight vehicles are typically those that do not have a detachable trailer, making them distinct from combination vehicles, which involve a towing and towed vehicle. In the context of this question, the classification of Class B is specifically focused on vehicles that are primarily designed for capability beyond standard cars or light trucks. Class B vehicles often include large trucks such as buses or heavy delivery vehicles that are used for commercial purposes. Other vehicles listed, such as combination vehicles (which fall under Class A licensing), light trucks, and motorcycles, do not meet the specific criteria required for Class B classification.
