What is the Gross Combination Weight (GCW)?

The weight of a single vehicle and its load
The total weight of a powered unit plus a trailer
The maximum weight a vehicle can carry
The weight of the trailer alone

The correct answer is: The total weight of a powered unit plus a trailer

The Gross Combination Weight (GCW) is defined as the total weight of a powered unit, such as a truck or tractor, combined with its attached trailer and the load it carries. This measurement is crucial for various reasons, including ensuring compliance with weight limits specified by regulations and maintaining safety on the roads. By understanding GCW, drivers can better manage their vehicle's performance and avoid potential hazards that may arise from exceeding weight limits. In this context, knowing the overall weight of the vehicle combination helps in assessing the proper handling characteristics, braking requirements, and licensing stipulations that a driver must adhere to. Weight limits are generally established to protect both the structural integrity of roads and bridges and ensure safe driving conditions. The other options offer specific weights or capacities that do not capture the complete picture of what GCW represents, which is why they are not the correct choice.
