Read Weighing Values and Compare with Standards: After the electronic truck scale stably displays the total weight of the vehicle and its cargo, compare it to the unified limits in GB 1589-2016 to determine if it is overloaded: 20 tons for two-axle vehicles, 30 tons for three-axle vehicles, 40 tons for four-axle vehicles, 50 tons for five-axle vehicles, and 55 tons for six-axle and above vehicles. Alternatively, compare it directly with the approved load capacity indicated on the vehicle's registration certificate; if it exceeds these limits, it is considered overloaded.
Confirm Equipment Validity: The electronic truck scale used for this determination must be certified by a legal metrology institution and be within its validity period. The value should be read when the "stable" indicator light on the instrument is illuminated to avoid misjudgments due to equipment inaccuracy or improper reading timing.
