What are the inspection items for vehicle safety inspection?

[LaMatthew]

Vehicle safety inspection items include: body appearance, braking system, steering system, lighting system, tire system, suspension system, and safety equipment inspections for each system. The body appearance mainly checks for cracks, deformations, or corrosion on the body, ensures windows are intact and complete, checks the condition of side and rearview mirrors, as well as wipers, engine, and radiator. The braking system includes self-inspection of the braking system, the working condition of the air pressure gauge, the air compressor belt, and the sealing of brake lines. The lighting system checks whether the front and rear lights are clean and intact, not loose, and functioning properly, including all signal indicators such as position lights, hazard warning lights, and front and rear fog lights. Tires should be inspected for cracks, bulges, wear level, and whether the tire pressure is normal. Safety equipment includes door emergency switches, roof escape hatches, safety hammers, and fire extinguishers.

There are quite a few vehicle inspection items, and what I care about most is driving safety. The staff will focus on checking the brake system to see if the braking force is sufficient and whether the brake discs and pads are severely worn. The lighting test is a mandatory item, including whether the low beams, high beams, and turn signals are functioning properly. The tire condition also needs to be carefully inspected—if the tread depth is below 1.6 mm, the tires must be replaced. During the chassis inspection, attention should be paid to whether the suspension system has oil leaks or deformations and whether the steering mechanism is flexible and reliable. Emissions testing is becoming increasingly strict, and exceeding the emission standards will definitely result in failure. Every time I go for the annual inspection, I make sure to check the seat belts and the window and door lift functions in advance, as these small details are the easiest to overlook.

Just accompanied a friend to the annual inspection station and found the testing items to be exceptionally comprehensive. The visual inspection is the first step, where the staff uses a ruler to measure the vehicle's dimensions and checks for any illegal modifications. Under the hood, they inspect the wiring harness fixation and the battery's condition. The chassis inspection is the most time-consuming, with the technician using a spotlight to check for leaks or deformities. The brake test is conducted on a roller platform, evaluating both the service brake and parking brake performance. There's also a steering system clearance test, ensuring the steering wheel's free play doesn't exceed standards. The emissions test must be done with the engine warmed up, and finally, they check if the OBD interface can properly read fault codes.

Vehicle safety inspection is like giving your car a comprehensive check-up. The lighting inspection checks if the brightness and beam angle meet standards, and the turn signal flashing frequency must also comply. Tire inspection examines tread depth and wear condition, with wheel alignment data being particularly important. Brake testing includes both dynamic and static checks, ensuring both foot brakes and hand brakes pass. The chassis inspection is the most thorough, covering critical components like suspension, drive shaft, and exhaust pipe. Emissions testing uses a five-gas analyzer to measure CO and HC emission levels. Finally, seatbelt functionality and window operation are also checked.

The safety inspection involves dozens of checkpoints across the entire vehicle. The exterior inspection includes checking the vehicle height and signs of illegal modifications. The lighting inspection is the most time-consuming, covering headlight height adjustment, fog light functionality, etc. The braking system test simulates braking force at various speeds on a roller bench, while the steering system inspection checks free play and return-to-center performance. Tire inspection uses a depth gauge to measure tread patterns while checking for abnormal wear. The undercarriage inspection focuses on the suspension and drivetrain components. The OBD diagnostic checks for fault codes in the electronic control system, with new vehicle registrations requiring an additional step of verifying the body VIN number. Emissions testing must be conducted with the engine at operating temperature, as cold-start data is invalid.

The vehicle safety inspection is as thorough as a household registration check, leaving no corner unchecked. The exterior inspection first examines the body for any damage and verifies the vehicle identification number. The lighting test includes over a dozen items, requiring that the high beams, low beams, fog lights, and turn signals all meet brightness and angle standards. The braking test is conducted on a testing platform, with the braking rate deviation between the front and rear wheels not exceeding 5%. During the chassis inspection, the mechanic uses tools to check wear-prone parts like ball joints and rubber bushings. Tire tread depth is measured with professional gauges, and all four tires must have a tread depth of at least 1.6 mm. The exhaust emission test includes two methods: the dual idle speed method and the simple working condition method, with emission values required to meet local registration standards.
