What is the minimum driver's license requirement to operate a truck with a GVWR of 45,000 pounds towing a 20,000-pound Farm Trailer?

To operate a truck with a Gross Vehicle Weight Rating (GVWR) of 45,000 pounds that is towing a 20,000-pound farm trailer, the minimum driver's license requirement is a Class B license.

A Class B license allows the operator to drive vehicles that have a GVWR of 26,001 pounds or more, and it is specifically designed for those who will be operating single vehicles or towing certain trailers. In this case, the truck's GVWR exceeds the 26,000-pound threshold, which necessitates at least a Class B license. Furthermore, towing a trailer with a weight of more than 10,000 pounds, which the farm trailer does, also falls within the regulations that a Class B license can accommodate.

In essence, the Class B license is appropriate for this situation as it ensures that the driver has the necessary skills and knowledge to safely operate a combination of vehicles that includes a heavy truck and a substantial trailer.
