Which class of vehicle is specially designed for carrying goods and operates commercially?

The correct choice is Class B, as vehicles classified under this category are specifically designed for commercial operations, primarily focusing on carrying goods. Class B trucks can include large box trucks, straight trucks, and some buses, all intended for the transport of cargo. This classification aligns with the regulations surrounding commercial driving, which require the appropriate licenses and inspections for vehicles used in business.

The other classifications do not fit this description for carrying goods in a commercial capacity. Class A vehicles typically involve combinations of vehicles with a Gross Combination Weight Rating (GCWR) exceeding a certain limit, often involving trailers, which are more suited for freight transportation in a combination setup. Class E vehicles generally refer to a specific category that may include lighter vehicles or those not primarily used for commercial hauling of goods. Class G vehicles usually encompass even smaller vehicle types intended for general use rather than exclusively for goods transportation.
