China 5 emission standard vehicles can continue to be driven until they are scrapped. There is no mandatory retirement period set by the state for private passenger vehicles. How long a China 5 vehicle can be driven depends on whether it meets the standards at the time of purchase - if compliant, it can remain in operation indefinitely. The China 6 standard will not affect the normal operation of China 5 vehicles, but only prohibits their sale and new registration. Currently, China has divided the "China 6 standard" into two phases: "China 6a" and "China 6b", with nationwide implementation planned for 2020 and 2023 respectively. The China 6 standard, officially known as the "National Sixth Stage Emission Standards for Motor Vehicles", was established to implement environmental protection laws, reduce and prevent automotive exhaust pollution, protect ecological environments, and safeguard public health.

I understand that China V vehicles are emission standards from around 2017, and now the policy is promoting China VI vehicles. However, I believe they can still be driven for at least 5 to 10 years, especially in rural areas or small cities. The issue lies with local traffic restrictions. Major and medium-sized cities like Beijing, Shanghai, and Guangzhou may impose restrictions first. For example, Beijing has already strictly controlled China III and China IV vehicles, and China V vehicles are likely to face obstacles after 2025. It is recommended to regularly check the latest policies on the vehicle management office website and ensure annual inspections to maintain exhaust emissions compliance. Don’t forget, good maintenance can extend the lifespan—replacing filters and reducing idling are effective for emission control. In the long run, the residual value of used cars drops quickly, but saving money by driving an old car is still worthwhile.

From an economic perspective, how long a China 5 vehicle can be driven depends on costs. With affordable maintenance and cheap repairs, I estimate it can last over 7 more years. However, the used car market trend shows rapid depreciation, making resale harder post-2025. New car replacement is costly, but China 6 models are more fuel-efficient. Balancing these, urban dwellers might upgrade sooner, while rural friends could hold out. I've seen owners drive decade-old cars—as long as the engine runs smoothly and passes inspections, there's no issue. Just watch battery and tire replacements, as they impact long-term economics.

As an environmental enthusiast, I believe that National V vehicles cause significant pollution, and policies are accelerating their phase-out. They won't be able to drive intercity for many more years. The government is promoting the National VI standard, and it's estimated that major cities will impose restrictions starting from 2023, while smaller areas may be more lenient. Switching to electric or hybrid vehicles sooner is wiser, saving fuel and reducing carbon emissions. With the current poor air quality, it's best to maintain your current vehicle well, but don't expect to keep it for too long. Based on personal experience, the chances of driving a National V vehicle for over 8 years are slim.
