Using physical knowledge, what are the hazards of vehicle overload? Only two.

1, when the stress area is the same, the greater the force, the greater the pressure, so the vehicle overload is easy to crush the road surface.

2. Inertia is an inherent property of an object. Under the same external force, the object with small acceleration has large mass and inertia, while the object with large acceleration has small mass and inertia. Inertia can maintain the original motion state of the object, so the buffer distance required for emergency braking when overloading is long, which is prone to traffic accidents.

Vehicle overload means that the vehicle exceeds the rated load when loading goods. The verification of overload mainly focuses on the performance of the vehicle and the driving safety caused by it.

Preventive measures for vehicle overload

First of all, vehicle overload has seriously damaged highway infrastructure. Because the load of overloaded vehicles far exceeds the design load of roads and bridges, the pavement is damaged, the bridge is broken and the service life is greatly shortened.

Second, the vehicle is overloaded, the mass increases, the inertia increases, the braking distance increases, and the danger increases. If it is seriously overloaded, it will cause accidents such as tire puncture, sudden deviation, brake failure and rollover due to excessive tire load and deformation. In addition, overloading will also affect the steering performance of the vehicle, and it is easy to cause accidents due to out-of-control steering.

Third, drivers who drive overloaded vehicles often increase their psychological burden and ideological pressure, and are prone to operational errors, which affect driving safety and cause traffic accidents.

Four, because the vehicle can not reach the normal speed after overloading, occupying the lane for a long time, which directly affects the smooth flow of roads.
