Which Class of Driver License allows driving single vehicles over 26,001 lbs with towing capacity up to 10,000 lbs?

The correct choice is associated with the classification of driver's licenses that pertains specifically to the operation of larger vehicles. A Class B driver license is designed for individuals who operate single vehicles with a gross vehicle weight rating (GVWR) of 26,001 pounds or more. This class also permits the towing of a trailer with a GVWR of up to 10,000 pounds, making it suitable for a variety of commercial and heavy-duty vehicles.

This classification is distinct from others as follows: Class A is meant for combinations of vehicles, where the combined weight exceeds certain thresholds; Class C is for ordinary passenger vehicles and small trucks that don't meet the thresholds set for Class B or A; and Class M is specifically for motorcycles. The Class B license accommodates those who may drive larger trucks or buses without requiring the additional complexities involved in towing heavier loads that Class A permits. Thus, for those driving heavy single vehicles with specified towing capabilities, Class B is the correct license class.
