Illinois CDL Practice Exam 2025 - Free CDL Practice Questions and Study Guide

To operate a vehicle that has a gross vehicle weight rating (GVWR) of 26,001 pounds or more, a Class A CDL is required. This class of license allows the holder to drive a combination of vehicles where the total combined weight exceeds 26,001 pounds, provided the towed vehicle exceeds 10,000 pounds in weight.

Class A is essential for managing larger commercial vehicles, such as tractor-trailers and large buses, reflecting the increased responsibility and skills needed to handle such vehicles safely. The requirement ensures that drivers have the necessary training and experience to manage the complexities involved with operating vehicle combinations of substantial weight.

In contrast, Class B allows the operation of single vehicles or combinations under certain weight constraints, while Class C is generally for smaller vehicles or those designed to transport 16 or more passengers. Class D typically pertains to regular passenger cars and is not suitable for commercial freight operations. Understanding these distinctions is crucial for anyone looking to pursue a career in trucking or transport.
