Can You Still Drive When the National VI Driver Warning Light Comes On?

It's better to err on the side of caution and not drive. Electronic Control Engine Fault: In electronic control engines, exhaust gas recirculation is used to reduce NOx emissions. In modern vehicles, due to the use of dual overhead camshaft variable valve timing, the exhaust gas recirculation valve has been eliminated. Therefore, it's possible that the filter screen position on the camshaft's timing control valve is clogged due to the use of inferior engine oil, preventing normal timing control. Three-Way Catalytic Converter Fault: It could also be an issue caused by the aging or failure of the three-way catalytic converter. However, National VI-compliant vehicles are generally still quite new, so the probability of this problem being caused by driver misconduct is higher. It might be due to frequent tire-burning starts leading to this secondary fault.
Having driven for many years, I can tell you that the National VI warning light is not something to take lightly. This light, usually yellow or red, indicates an issue with the emission system, such as a clogged DPF or faulty sensor. If the yellow light comes on, you can still drive the car for a short distance, but at a reduced speed, and head straight to a repair shop for inspection. However, if the red light flashes, you must stop driving immediately and pull over to seek help. Why? Because continuing to drive could damage the engine or even cause the car to stall mid-journey. I know someone who ended up paying a hefty repair bill due to procrastination. I recommend keeping a simple diagnostic tool in your car to quickly identify the issue. Don’t skimp on regular maintenance—use low-ash engine oil to reduce carbon buildup. Safety first—never take risks on the road.
As someone frequently involved in car maintenance, I suggest not panicking when the China VI warning light comes on. This light indicates the OBD system has detected excessive emissions, commonly due to a clogged urea system or wiring short circuit. With a yellow light, you can drive slowly for short distances; a red light requires immediate stopping. I've seen too many cases where continued driving led to catalytic converter damage, doubling repair costs. Quickly visit a professional shop for diagnosis, such as using a scanner to read fault codes. Unrepaired emission issues can affect annual inspection and environmental tests. Pay attention to engine sound changes while driving; stop immediately if there's any shaking. Regularly check the oil dipstick and air filter to prevent problems before they occur.
