What are the criteria for classifying a vehicle as an accident-damaged car?

Main determining points include the vehicle's ABC pillars, front and rear longitudinal beams, and shock absorber mounts. Below is an introduction to relevant automotive repair content: Definition of Sheet Metal Repair: Sheet metal repair for motor vehicles is performed when the vehicle's exterior is damaged or deformed, requiring the use of sheet metal repair methods to restore the damaged areas. Sheet metal repair places relatively high demands on technicians, who must understand the characteristics of body materials, the stress properties of the vehicle body, and the welding techniques involved. Only with this foundational knowledge can a technician properly perform sheet metal repairs. Post-Repair Precautions: After an accident-damaged car is repaired, it is advisable to keep the engine speed below 4,000 rpm. Newly replaced parts require a break-in period and are not suitable for high-intensity operation; vehicle speed should also be kept moderate. After driving a certain distance, the vehicle should be taken to a repair shop for testing of relevant data, such as whether the tires are wearing evenly or if the suspension components are deformed, with necessary corrections made as required.
The classification standards for accident-damaged vehicles generally refer to whether the vehicle has experienced a major collision affecting structural safety. Common criteria include checking if the vehicle's frame has undergone deformation or repairs, such as damage to the A-pillar or longitudinal beams, which can reduce the vehicle's stability. Another factor is whether the airbags have deployed—once deployed, it indicates a high-impact collision, categorizing the vehicle as high-risk for being an accident car. Additionally, significant components like the engine or chassis, if damaged and repaired after an accident, may also classify the vehicle as such. From my experience in auto repair, detecting accident-damaged vehicles involves reviewing insurance claim records and repair shop inspection reports. If repair costs exceed approximately 30% of the vehicle's original value, insurance companies typically label it as an accident car. In the used car market, such vehicles depreciate significantly. Buyers should carefully inspect body panel gaps for alignment to avoid future safety risks. Remember, structurally damaged vehicles tend to feel unstable at high speeds, posing significant safety hazards.
