What is the meaning of the term "curb weight"?

The term "curb weight" specifically refers to the weight of a vehicle when it is ready for operation, with all necessary fluids (such as oil, fuel, and coolant) included but without any passengers or cargo. This definition is crucial for understanding vehicle specifications and weight classifications.

Curb weight provides a baseline measurement for the vehicle's weight in its standard operational state, making it essential for determining load capacity, fuel efficiency, and vehicle handling characteristics. Understanding this weight helps drivers gauge how much cargo they can safely add without exceeding the vehicle's maximum allowable weight.

While other answers reference aspects of a vehicle’s weight, they do not align with the standard definition of curb weight. For instance, mentioning passengers and cargo adds elements not included in the curb weight definition, and focusing solely on fluids or accessories also misses the fundamental component of the vehicle being operational. Thus, option B accurately encapsulates the definition of curb weight within the context of vehicle specifications.
