Which warning lights will cause a vehicle to fail the annual inspection?

Any illuminated warning lights, including the engine warning light and oil pressure warning light, will cause a vehicle to fail the annual inspection. Below are details about vehicle annual inspections: 1. Purpose: To promptly eliminate potential vehicle safety hazards, encourage proper vehicle maintenance, and reduce traffic accidents. 2. Inspection process: Emissions testing, violation check, deposit payment, visual inspection, on-site testing, final review, fee payment, and certification collection. 3. Required materials for individual inspection: Original vehicle license, duplicate of compulsory traffic insurance, ID card copy, and the vehicle. 4. Required materials for corporate inspection: Original vehicle license, duplicate of compulsory traffic insurance, agent's ID card copy, and the vehicle.

Last time I went for the annual inspection, I saw several cars held up because their warning lights were on. The critical ones that must not be lit are the engine fault light, ABS fault light, and airbag light. An illuminated engine light could indicate excessive emissions or mechanical issues, directly affecting the exhaust test. ABS and airbag lights are related to active safety system failures, so inspectors must be strict. The brake fault light is especially critical since brake failure is no joke. I also noticed that the tire pressure warning light shouldn’t be ignored—though it may seem minor, it’s related to tire safety. Additionally, the oil pressure light and battery indicator, which involve the powertrain, must be addressed beforehand. To be safe, it’s best to ensure all dashboard warning lights are off before the annual inspection.

Once when I was helping a friend with their annual vehicle inspection queue, the car in front was turned away because its airbag light was on. The inspector said any warning light directly related to vehicle safety cannot be illuminated—for example, an engine light might indicate incomplete combustion, which would definitely fail emissions; a brake fault light signals an issue with the braking system, and who would dare let such a car on the road? An ABS light means there's a problem with the anti-lock system, making the car prone to skidding in rainy weather. Additionally, the oil warning light and tire pressure monitoring light should be heeded—the former affects engine lifespan, while the latter impacts handling stability. I recommend getting a comprehensive check-up at a repair shop a month in advance, rather than scrambling on the day of the inspection.

The annual inspection is most dreaded when warning lights appear on the dashboard. The engine malfunction light, airbag light, and brake warning light are definite failures as they involve core safety systems. An illuminated ABS light is also unacceptable, indicating the anti-lock braking system has failed. While less common, an oil pressure warning light will absolutely cause rejection. These warning lights represent genuine safety hazards, and inspection stations won't overlook them. It's best to have mechanics scan for trouble codes during annual maintenance to address issues beforehand and avoid inspection troubles.

Last year, my neighbor's car failed the annual inspection because the tire pressure warning light was on. In fact, any safety-related warning light being illuminated will cause a failure, such as the engine fault light affecting emission compliance, the brake system fault light being the most hazardous, and the airbag light indicating passive protection failure. Other lights like the ABS light, EPC electronic throttle fault light, and oil warning light will also result in failure. If any of these lights are on, it proves the vehicle's condition does not meet the standards, and the annual inspection is not just a formality. It is recommended to check the dashboard yourself half a month in advance and fix any issues promptly.
