What are the items for motor vehicle safety inspection?

Vehicle safety inspection includes three major parts: whole vehicle inspection, engine inspection, and chassis and body inspection. Introduction to vehicle safety inspection: In recent years, due to the sharp increase in the number of motor vehicles, the issue of motor vehicle safety operation has become increasingly prominent. Strengthening the management of motor vehicles and paying attention to the safety technical inspection of motor vehicles have become important topics that need to be studied and solved urgently by the whole society, especially the public security traffic management departments, and also provide a good opportunity for the development of motor vehicle safety technical inspection. Classification of vehicle safety inspection: The inspection work is based on the above classification and operates according to the performance of the vehicle. The main performance of the vehicle is divided into power performance, economy, safety, reliability, environmental protection, handling stability, passability, and ride comfort. Therefore, the inspection of the vehicle starts from the inspection of these performances. Vehicle safety inspection includes three major parts: whole vehicle inspection, engine inspection, and chassis and body inspection.
The main focus of a motor vehicle safety inspection includes several key areas: First, the vehicle's exterior, such as whether there are severe scratches or rust holes on the body, if the tire wear exceeds the safety limit, and if there are cracks in the lamp covers affecting light transmission. Second, the dynamic chassis test, which includes checking the braking performance to ensure the braking distance meets standards, and whether the steering wheel is loose or misaligned. Third, the emission test to verify if the exhaust emissions meet environmental standards, which is particularly important for environmental protection. Fourth, checking safety equipment, such as whether seat belts function properly, if the fire extinguisher is within its validity period, and if the warning triangle is complete. There's also a test for headlight brightness, as dim headlights are unsafe for night driving. Regular inspections can prevent many safety hazards. I recommend that vehicle owners check their tires and lights in advance to avoid last-minute hassles during the inspection.
For the annual inspection, I pay the most attention to the chassis check, mainly the steering and braking system tests. Loose steering ball joints or excessively worn brake pads can directly affect driving safety. Additionally, it's necessary to inspect whether the vehicle's body structure has any deformations—for example, a weakened frame due to a previous accident can be very dangerous. The lighting test should verify if the actual brightness of the low and high beams is sufficient, especially since light intensity on highways directly impacts visibility. There's also the tire tread depth inspection; if the tread is worn out, the grip weakens, making the car prone to skidding in rainy conditions. The exhaust emission test is becoming increasingly important now, as failing to meet emission standards will result in failing the inspection. I usually replace the brake pads and lights before the inspection to increase the chances of passing it in one go.
Vehicle annual inspection is divided into two major parts: appearance and functionality. The appearance check examines the integrity of the body; paint damage must not expose metal, tire sidewalls must not have bulges, and light covers must be clean. The most critical part of the functionality test is braking performance, typically measured using a roller platform to test the braking ratio of each wheel—imbalance between left and right wheels indicates an issue. The steering wheel's ability to self-center is also tested; misalignment suggests inaccurate wheel alignment. Safety equipment checks include fire extinguisher pressure values and seatbelt buckle reliability. Additionally, exhaust emissions are tested to ensure compliance with local standards, with current National VI emission regulations being particularly strict. Many vehicles fail repeatedly due to emission issues, so it's recommended to go to an official inspection station to avoid costly secondary repairs.
