To legally operate a truck with a GVWR of 27,000 pounds, what type of driver's license is mandatory?

To legally operate a truck with a Gross Vehicle Weight Rating (GVWR) of 27,000 pounds, obtaining a Commercial Driver's License (CDL) B is necessary. A CDL B allows the driver to operate single vehicles with a GVWR of 26,001 pounds or more, as well as tow a vehicle that weighs no more than 10,000 pounds.

In the case of a truck with a GVWR of 27,000 pounds, the vehicle exceeds the threshold that generally requires a regular driver's license, thus making a CDL B mandatory for legal operation. This requirement is in place to ensure that drivers of larger commercial vehicles have the necessary training and skills to handle the increased size and weight, which can impact vehicle handling and safety on the road.

While options indicating other types of licenses exist, they do not meet the legal requirements for operating vehicles of that particular weight category.
