What Does Maximum Allowable Total Mass Mean?

[LillianFitz]

Maximum allowable total mass of a vehicle refers to the total weight when the vehicle is fully equipped and loaded with passengers (including the driver) and cargo as per regulations. The regulations for maximum allowable total mass vary for different vehicle types as follows: 1. Passenger cars: Total vehicle mass = curb weight + driver and passenger weight + luggage weight; 2. Buses: Total vehicle mass = curb weight + driver and passenger weight + luggage weight + accessory weight; 3. Trucks: Total vehicle mass = curb weight + driver and assistant weight + luggage weight. Determining a vehicle's maximum allowable total mass should consider the following major factors: 1. It must be appropriate for the vehicle's intended use and operating conditions; 2. The load capacity of various vehicle types should be reasonably classified to facilitate product serialization, generalization, and standardization; 3. The extent of modifications required for existing production equipment and lines and their availability should be considered.
