What are the restrictions on yellow-label vehicles?

Green environmental roads have full-day or daytime traffic restrictions. Please refer to the notices from local environmental protection departments for specific details. The following is an introduction to yellow-label vehicles: 1. Yellow-label vehicles are a general term for high-pollution emission vehicles: These are gasoline vehicles that do not even meet the National I emission standards or diesel vehicles that do not meet the National III emission standards. They are called yellow-label vehicles because they are issued yellow environmental labels. 2. Characteristics of yellow-label vehicles: Yellow-label vehicles have high emission volumes, high concentrations, and poor emission stability. Due to outdated exhaust emission control technology, the exhaust emissions of these vehicles do not meet the Euro I standards, with emissions equivalent to 5 to 10 times that of new vehicles. The identification of yellow-label vehicles is based on exhaust emission standards. China implemented the 'Light-Duty Vehicle Pollutant Emission Limits and Measurement Methods (I)' in 2001, which is equivalent to the Euro I standard. The 'Light-Duty Vehicle Pollutant Emission Limits and Measurement Methods (III)' implemented in 2007 is equivalent to the Euro III standard. Therefore, the National I emission standard stipulates that carbon monoxide must not exceed 3.16 grams per kilometer, hydrocarbons must not exceed 1.13 grams per kilometer, with the particulate matter standard for diesel vehicles not exceeding 0.18 grams per kilometer, and a durability requirement of 50,000 kilometers. The National III emission standard stipulates that hydrocarbons must not exceed 0.66%, carbon monoxide must not exceed 2.1%, particulate matter must not exceed 0.1%, and nitrogen oxides must not exceed 5%.
