Loading goods on road vehicles when participating in road traffic must comply with regulations on the total weight of the vehicle, vehicle axle load, vehicle cluster, height, width, and permitted loading length of the vehicle and must not exceed the weight of the goods transported allowed to participate in traffic stated in the certificate of technical safety and environmental protection inspection of the vehicle, except in cases of being granted a license to circulate overloaded vehicles, oversized vehicles, oversized vehicles, and oversized vehicles transporting goods on the road.
Goods loaded on vehicles must be neatly arranged, arranged evenly, tightly tied, loaded, and lininged to ensure no shifting to the directions, verticals, and vertical directions; ensure environmental sanitation regulations; do not let splashes fall when the vehicle is participating in traffic; do not obstruct the driver's vision; do not cause dis imbalance of the vehicle or cause difficulties for the driver when driving; do not cover the lights, registration plates, and safety warnings of the vehicle.

The height of loading goods on road vehicles is regulated as follows:
For open-top trucks, the allowable loading height is the limited height within the vehicle's cargo range according to the design stated in the vehicle's certificate of technical safety and environmental protection inspection.
For uncovered open-top trucks, goods loaded on the vehicle exceeding the height of the vehicle's trunk according to the design stated in the vehicle's certificate of technical safety inspection and environmental protection must be tied, sealed, and inserted securely to ensure safety when participating in road traffic.
The height of goods loading must not exceed the height prescribed below, calculated from the highest point of the road surface on which the vehicle runs or higher:
Vehicles with a designed weight of goods of 5 tons or more stated in the vehicle's certificate of technical safety and environmental protection inspection: the loading height of goods shall not exceed 4.2 meters.
Vehicles with a designed weight of goods transported from 2.5 tons to less than 5 tons stated in the vehicle's certificate of technical safety and environmental protection inspection: the loading height of goods shall not exceed 3.5 meters.
