Illinois CDL Practice Exam

Question: 1 / 400

What does GCWR stand for in the context of Illinois CDL practice?

Gross Combination Weight Rating

Gross Combination Weight Rating refers to the maximum weight rating specified by the vehicle manufacturer for a combination vehicle, which includes a towing vehicle and its trailer or trailer combination. It is important because it helps ensure that the vehicle is not overloaded, which can lead to safety hazards and mechanical failures. Adhering to the GCWR is crucial for compliance with regulations and to maintain the vehicle's operational integrity.

The other terms relate to vehicle classifications and ratings but do not specifically address the combined weight of towing and towed vehicles in the same manner as GCWR. For example, Gross Vehicle Weight Rating pertains solely to a single vehicle's maximum weight, while Class A and Class B refer to specific classifications of commercial driver's licenses, which categorize vehicles based on their size and weight capacities.
