What is unladen weight on a vehicle?

Unladen weight, also known as kerb weight, is the weight of a vehicle excluding any passengers, luggage or cargo. It includes the weight of the vehicle itself, including its engine, fuel, fluids, and any permanently installed accessories such as a spare tire, jack, and tools. The unladen weight is typically specified by the vehicle manufacturer and can be found in the vehicle's owner's manual or on a label affixed to the vehicle, often in the driver's door jamb or under the hood. Knowing the unladen weight of a vehicle is important for determining its load capacity, which is the maximum amount of weight that the vehicle can safely carry, including passengers and cargo. It also plays a role in calculating fuel efficiency and emissions, as heavier vehicles generally consume more fuel and produce more emissions.
