China V emission standard is marked with the Roman numeral V, while China VI emission standard is marked with the Roman numeral Ⅵ. When purchasing a new car, the salesperson will provide a vehicle acceptance form, which includes the model, color, emission standard, engine number, and chassis number. Here are some relevant details: 1. The China VI emission standard is known as the world's highest emission standard. 2. First, you can visit the Motor Vehicle Environmental Protection Website and enter the chassis number or engine number to check if the vehicle meets China VI standards. Alternatively, the vehicle's compliance certificate will clearly indicate the emission standard. 3. The environmental information accompanying the vehicle, such as the vehicle's conformity certificate, is a more direct way to identify the emission standard.

As a seasoned driver with years of experience, I find it quite easy to identify China 5 and China 6 vehicles. First, check the environmental label, usually located on the top left corner of the windshield or the nameplate on the door frame, marked as China V or China VI, with VI indicating China 6. Documents like the vehicle license or registration certificate clearly state the emission standard in the emissions section—don’t forget to check. The VIN, or chassis number, is also crucial; scan it with a mobile app or check it on a government environmental website by entering the number to get the standard result. With many traffic restrictions now in place, distinguishing between them is important. For example, my neighbor mistakenly drove a China 5 vehicle into a restricted zone and got a ticket. Most new cars after 2017 are China 6, so checking the production date is reliable when buying a used car. Just glance at the label when parking—it becomes second nature over time.

When working in our auto repair shop, we often encounter car owners who can't distinguish between China 5 and China 6 emission standards. I usually teach them to start with physical indicators: the environmental label under the hood or near the dashboard is most intuitive – China 6 is clearly marked as VI. Checking the VIN is more convenient – the eleventh character indicates the emission standard, which can be easily decoded using online tables. Modern tools like OBD diagnostic interfaces connected to computers can accurately read emission data. Don't overlook documents – the vehicle conformity certificate or manual provides detailed specifications. Nowadays, there are differences in repair parts – China 6 has stricter requirements, so avoid damaging the car with minor mistakes. During inspections, pay attention to label integrity to avoid counterfeits. It's simple to get started – test a few times and you'll become familiar.

As a first-time car buyer, I was initially confused about China 5 and China 6 emission standards. After some research, I learned that you can simply check the environmental label on the windshield or door frame—China VI indicates China 6. The salesperson demonstrated this to me, and the contract and certificates also stated the standard, so don’t just rely on verbal claims. Scanning the QR code on your phone quickly retrieves the info, or you can enter the VIN on the official website for confirmation. When choosing a car, I prioritized China 6 because some cities restrict older vehicles, avoiding future hassles. Most cars produced after 2020 are China 6, but remember to check if the label is damaged. My friends said I was lucky—spending just a few minutes before buying saved me a lot of trouble.
