Green label vehicles refer to gasoline vehicles that meet the National I standard or above and diesel vehicles that meet the National III standard or above in terms of exhaust emission environmental inspection, and are issued green environmental protection labels by the environmental protection department. The establishment of yellow label vehicles and green label vehicles is to alleviate urban traffic congestion and air pollution, and promote the elimination of old vehicles. The "green label" also has a validity period. After the expiration of the environmental protection label, the vehicle must undergo exhaust emission testing according to regulations and obtain a new label based on the results. Non-green label vehicles are those that do not meet these requirements. Precautions for highway driving: 1. Drive in the designated lane: Highways have clearly marked lanes, including dedicated lanes for large vehicles, small vehicles, etc. When overtaking, once you occupy a lane, return to your own lane promptly after completing the overtaking maneuver, and do not occupy other lanes for an extended period. Additionally, emergency lanes should not be occupied for long periods without special reasons. 2. Maintain a safe speed and avoid speeding: The dangers of speeding are well-known, whether on local roads or highways, it can lead to irreversible consequences. 3. Maintain a safe longitudinal distance between vehicles: Under normal conditions, on dry roads with good braking, the distance between vehicles (in meters) should not be less than the speed (in km/h). For example, at 80 km/h, the distance should be no less than 80 meters, and at 100 km/h, no less than 100 meters. Always pay attention to roadside distance markers. In rainy, foggy, snowy, or wet road conditions, the distance should be more than doubled. 4. Pay attention to traffic signs: Always be aware of roadside and overhead signs and markings while driving, and keep to the right appropriately to avoid running over the right lane divider, allowing sufficient lateral distance for overtaking vehicles. 5. Do not arbitrarily occupy emergency lanes in case of traffic accidents: Traffic accidents are inevitable on highways. If other vehicles cause a traffic jam, do not occupy the emergency lane arbitrarily, as it may prevent rescue vehicles from performing their duties. 6. Avoid fatigued driving and take timely breaks: Fatigued driving is extremely dangerous on highways. When fatigued, a person's reaction ability decreases, making it difficult to respond correctly to sudden situations.

Non-green label vehicles are essentially older models that failed to meet environmental protection standards! I used to drive a 2002 Santana, which got a yellow sticker during its annual inspection. These vehicles exceed exhaust emission limits and are now banned from many major city centers—for instance, Beijing restricts yellow-label cars within the 5th Ring Road. Fundamentally, it's a classification based on national emission standards: gasoline cars below China I and diesel vehicles below China III generally fall into this category. To check if your car is a non-green label vehicle, the most straightforward way is to look at the color of the environmental label on the windshield—a green round mark means compliant, while a yellow triangular mark indicates a non-compliant older car.

Last time when helping a friend check out a used car, I came across this concept. Simply put, non-green label vehicles refer to those that fail to meet emission pollution control standards. Environmental protection departments issue different colored labels based on inspection results. Older vehicles meeting National Phase 0 or Phase 1 standards basically can't obtain green labels. Currently in China, cities like Shenzhen and Shanghai have established green label zones - non-green label cars caught entering by electronic surveillance will be fined. This classification mainly aims to phase out highly polluting older vehicles. When buying used cars, special attention must be paid to this point. Some older imported models may have good performance but could become restricted yellow label vehicles due to emission issues.

Non-green label vehicles are those that fail to meet the environmental protection classification standards. In China, vehicles are categorized into five emission levels. National I and National II standard vehicles are classified as yellow-label vehicles, while only National III and above qualify for green labels. Inspection stations measure pollutants like CO and HC in the exhaust emissions, and vehicles exceeding the standards are issued yellow labels. Such vehicles usually face traffic restrictions or even mandatory scrapping, with diesel trucks being subject to stricter controls. Last month, that small truck emitting black smoke at the neighborhood entrance was towed by traffic police precisely because it was a yellow-label vehicle.
