Which class of driver's license is NOT related to large commercial vehicles?

The correct choice indicates that Class D is not related to large commercial vehicles. In Illinois, a Class D driver's license is intended for operating standard passenger vehicles, such as cars, SUVs, and small trucks that do not exceed specific weight limits. This license type does not encompass the larger commercial vehicles that require more advanced skills to operate due to their size and weight, which are handled under Class A, B, and C licenses.

Classes A and B are specifically designated for various types of commercial driving. Class A licenses allow drivers to operate combination vehicles with a gross vehicle weight rating (GVWR) of 26,001 pounds or more, including trailers exceeding 10,000 pounds. Class B licenses permit drivers to operate single vehicles with a GVWR of 26,001 pounds or more, or buses designed to transport passengers. Class C is typically for smaller commercial vehicles not included in Class A or B, such as vehicles transporting hazardous materials or passenger vans.

Therefore, Class D is clearly distinct from these classes and focuses on the everyday operation of non-commercial vehicles.
