Which class of driver's license includes vehicles with a GVWR of 26,001 pounds and up?

The class of driver's license that includes vehicles with a Gross Vehicle Weight Rating (GVWR) of 26,001 pounds and up is known as Class A. This type of license is specifically designed for operators of commercial vehicles, and it allows the driving of combination vehicles that have a total GVWR exceeding this threshold.

In many jurisdictions, including Illinois, a Class A license permits the driving of trucks with a GVWR of 26,001 pounds or more, especially when towing a trailer that weighs more than 10,000 pounds. This classification is important for commercial truck drivers and others who operate large vehicles, ensuring they have the necessary training and understanding of handling such significant weights and sizes on the road.

The other classes mentioned, such as Class C and Class D, cover lighter vehicles and, typically, non-commercial use. Class M is specifically for motorcycles. Thus, Class A is the only licensing category that encompasses operations of vehicles with a GVWR of 26,001 pounds and above, making it the correct answer.
