2021 was a difficult year for National III vehicles to pass inspection. Here are the specific details about National III vehicles: 1. Phase-out of National III: Some provinces planned to phase out a sufficient number of National III vehicles by the end of 2020. Many major cities have begun implementing policies to stop annual inspections for National III vehicles, leading to their eventual phase-out. 2. Annual Inspection: For National III passenger cars, annual inspections follow the normal cycle—once a year within 15 years, and twice a year after exceeding 15 years, until reaching 600,000 kilometers. 3. National III Diesel Vehicles: Operational National III diesel trucks are uniformly not eligible for regular emission inspections. 4. Inspection Suspension: In 2021, National III vehicles could still pass annual inspections and barely remain on the road. However, the phase-out policies continue, coupled with widespread driving restrictions, bans, and the implementation of policies to stop annual inspections, National III vehicles may face elimination.

I've been driving a China III emission standard car for several years, and it has always passed the annual inspection without issues. Just last week, I took it to the testing station again. As long as the exhaust emissions meet the standards, and the lights and brakes are functioning properly, there are generally no obstacles. However, I've heard that policies are tightening in major cities like Beijing, Shanghai, Guangzhou, and Shenzhen, where there might be restrictions, while smaller cities remain more lenient. I make sure to maintain my car on time, changing the oil and cleaning the filters, which significantly improves the pass rate. Don't wait until the deadline to avoid fines or extra trips. It saves money and hassle—even though the car is a bit old, it runs well, and buying a new one would cost a fortune. Also, don't overlook checking the chassis and tires; safety comes first. Remember to bring all the necessary documents like the vehicle license and insurance policy, and booking an appointment in advance saves time.

As someone who has some knowledge about cars, the annual inspection of China's National III standard vehicles focuses on the emission system. The exhaust test checks whether the CO and HC values are high, and the catalytic converter is prone to problems due to aging. Regular maintenance includes using an OBD scanner to check for fault codes, cleaning the throttle body, and replacing the air filter to prevent exceeding standards. New regulations have tightened emission standards in some cities, but most areas nationwide still allow inspections. It is recommended that car owners pay attention to local notifications, as cities like Beijing already have traffic restrictions. Checking wiring connections and spark plugs yourself can save money and be efficient. From a technical perspective, as long as maintenance is good, National III vehicles can still be on the road for a few more years.

I usually drive my kids to school, and my National III emission standard vehicle passes the annual inspection smoothly every year. Just bring all the required documents to the testing station, and they'll check the lights, brakes, and exhaust emissions thoroughly. Safety is the top priority - passing the inspection ensures the brakes are responsive, giving me peace of mind when driving at night. If the exhaust emissions occasionally exceed the limit, a cleaning service can solve the problem. Don't wait until it's overdue and face fines. Maintaining an older car well saves big money and keeps the kids safe. Simply make an appointment, queue up, and don't forget to keep daily maintenance records.
