Do private cars usually get checked for overloading?

[Miranda]

Yes, traffic police will impose penalties for overloading if detected. Due to the limited interior space of private cars and their relatively high speeds on the road, accidents occurring under overloaded conditions are often much more severe than when carrying normal passenger loads. Hazards of vehicle overloading: 1. Damage to road infrastructure: Roads in China are designed with specific load limits. Overloaded vehicles can cause significant damage to road surfaces, as the actual load far exceeds the designed capacity of roads and bridges, leading to pavement deterioration, bridge fractures, and substantially reduced service life. 2. Increased driving risks: Overloaded vehicles have greater mass, which increases the vehicle's inertia and braking distance, making driving less stable and more dangerous. Severe overloading can also damage tires, potentially causing blowouts or sudden deviations due to excessive deformation. 3. Increased post-accident risks: Vehicle safety features are designed based on standard passenger capacity. In overloaded conditions, passengers beyond the designed capacity may not receive adequate protection.
