Vehicle inspection tests primarily include checking the car's braking system, the functionality of all exterior lights and high beams, a basic examination of the chassis, and the horn system. Generally, there are no major issues during the inspection; the main focus is on verifying whether the vehicle has been modified without authorization and if the basic registration information matches the vehicle's records. Before the inspection, the owner will receive a checklist detailing items such as brakes, lights, and horn. The annual vehicle inspection mainly examines the engine, chassis, and paintwork to ensure everything is complete, the paint is in good condition, and the vehicle's braking and handling meet the "Technical Requirements for Safe Operation of Motor Vehicles." Any discrepancies should be corrected as required.

I know vehicle inspection like the back of my hand! It mainly focuses on three major aspects: safety, emissions, and compliance. Let's start with safety checks—you gotta test whether the brakes work properly, with each wheel's braking force measured precisely on a dynamometer; check if the steering wheel aligns correctly, if the chassis is stable, and if the lights are bright enough and angled properly—all need thorough inspection. Emissions standards are getting stricter—they stick a probe into the exhaust to measure toxic gases like CO, HC, and NOx to see if they exceed limits, especially for China VI vehicles. Exterior inspections are also meticulous, verifying if the VIN matches, checking for illegal modifications, rejecting overly dark window tints, and failing you if the tire treads are worn down. Remember, small issues like lights and brakes are the most common pitfalls—pre-inspecting can save you a lot of trouble.

Recently, I accompanied my buddy for the annual vehicle inspection and finally understood the process. The inspection line consists of several major checkpoints: On the brake tester, a few hard stomps immediately reveal whether the braking force between the front and rear wheels is balanced. Underneath the chassis, inspectors use mirrors to check for leaking ball joints or loose suspension. The headlight tester measures brightness, color temperature, and deviation with precision. The most critical part is the emissions test—front-wheel-drive cars are placed on rollers with their wheels spinning wildly, while an exhaust probe analyzes the tailpipe emissions. Standards differ between China V and China VI, and older cars often fail here. A word of advice: If you've modified your wheels, suspension, or applied dark window tints, revert them to stock before lining up to avoid a wasted trip.

Last year, I spent half a day queuing for the annual vehicle inspection and summarized several key items: For safety, the brakes are the main focus, testing the braking force of each wheel and the left-right difference; the headlight tester checks both brightness and beam deflection angle simultaneously; the side slip tester can identify wheel alignment issues. Emission testing is becoming increasingly intelligent, directly reading OBD data streams combined with emission checks, with more complexity for China VI vehicles. It's advisable to address minor issues like yellowed bulbs or brake noises in advance, ensure sufficient tire tread depth, and always have a warning triangle on hand. Special reminder: Vehicles with added turbochargers or modified exhaust pipes will likely fail inspection.
