What does non-green label vehicle mean?

[MacAurora]

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.
