What do the terms 'curb weight' and 'gross weight' mean on a vehicle license?

[SanWyatt]

The gross weight on a vehicle license refers to the total weight of the vehicle when fully equipped and loaded with passengers (including the driver) and cargo as per regulations, i.e., the fully loaded gross weight. The gross weight equals the curb weight plus the approved load capacity plus the passenger weight (number of seats × 65kg). The curb weight is the fully equipped weight of the vehicle, also traditionally referred to as the 'empty weight,' which includes the weight of all components such as lubricants, fuel, onboard tools, spare tires, etc. The curb weight listed on the vehicle license is an important design indicator for the vehicle. This indicator must be both advanced and practical, closely related to the vehicle's design level, manufacturing quality, and industrialization standards. Under the same model conditions, optimized design methods, superior production levels, and high industrialization standards will result in a reduced curb weight.
