What defines a Class B license in terms of weight?

A Class B license is designated for operating a vehicle that meets specific weight and towing criteria. Specifically, a Class B license allows for the operation of a single vehicle with a gross vehicle weight rating (GVWR) of more than 26,000 lbs, which may also include towing specific trailers. Option D correctly captures the essence of this license classification by indicating that a vehicle can be over 26,000 lbs while also towing a nonfarm trailer weighing up to 10,000 lbs. This ability to tow a specific weight in addition to the primary vehicle's weight is central to understanding the purpose of a Class B license.

The other considerations related to the Class B license include the distinction between vehicles that are primarily designed for carrying passengers versus cargo, as well as the operational requirements set forth for larger vehicles. The correct definition highlights the versatility given to a Class B license holder regarding both vehicle weight and towing capacity, which is crucial for conducting various transportation jobs.
