Running a yellow light and running a red light are both categorized under the same traffic violation—driving a motor vehicle in violation of traffic signal regulations. According to Article 90 of the 'Road Traffic Safety Law of the People's Republic of China,' a fine of 200 RMB and 6 penalty points will be imposed. The yellow light at an intersection serves as a warning. Motor vehicles should slow down when approaching the intersection. If a vehicle has already crossed the stop line when the yellow light turns on, it may continue to pass through. However, if the vehicle has not yet crossed the stop line, it should come to a stop. Article 38 of the 'Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China' states the following for motor vehicle and non-motor vehicle traffic signals: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of through vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to pass through. When the red light is on, vehicles are prohibited from proceeding. At intersections without non-motor vehicle or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle traffic signals. When the red light is on, right-turning vehicles may proceed if they do not obstruct the passage of through vehicles or pedestrians. Electronic surveillance captures red-light violations based on the following three photos, which are reviewed by traffic police to determine whether a red light was run: An image of the vehicle not having passed the stop line when the red light turns on. An image of the vehicle's front wheels crossing the stop line. An image of the vehicle's entire body having crossed the stop line. If these three photos show that the vehicle moved beyond the stop line while the red light was on, the traffic police can confirm it as a red-light violation during review. To avoid running a yellow light: slow down when approaching an intersection, maintain a speed of 20–30 km/h, keep a safe distance from the vehicle ahead to prevent rear-end collisions or rushing through a yellow light. Alternatively, pay attention to the traffic signals in advance—observe the duration of the green light when it is on. If traffic is light and the green light duration is long, prepare to slow down.

After driving for so many years, I think strictly speaking, running a yellow light doesn't count as running a red light. But the key point is, when the yellow light comes on, you need to quickly judge whether you can stop safely. If the front of your car has already crossed the white line, then keep going; but if you could have stopped steadily yet insisted on going through, then that counts as a violation. I once saw a new driver stomp on the accelerator to rush through a yellow light and ended up getting caught by the camera and fined 200 yuan. Traffic lights change quickly when driving, and the yellow light is just a reminder for you to slow down in advance to avoid trouble. Make it a habit to check the lights early and avoid rushing—safety is more important than anything.

As a parent, I often worry about driving safety. Running a yellow light is different from running a red light—the former may be a violation, while the latter is absolutely prohibited. Forcing your way through when the yellow light is flashing can easily lead to rear-ending the car in front or endangering pedestrians, especially in school zones with many children. When teaching kids to cross the street, we also emphasize stopping at red lights, going at green lights, and being cautious at yellow lights. Legally, running a yellow light may result in fines or demerit points, but given the high accident rates, it's best to stay cautious every second. Tips like slowing down, maintaining a safe distance, and braking early are practical every day to keep your family safe.

I just got my driver's license last month. In class, I learned that a yellow light means slow down and prepare to stop, not accelerate to rush through. Running a red light has zero tolerance, but if you've crossed the line during a yellow light, it's safer to continue rather than brake abruptly. Traffic laws treat these two scenarios differently—the former results in stricter penalties, while the latter depends on the situation. It's common for cameras to capture failure-to-stop behaviors, which deduct 3 points. When driving, pay more attention to signal changes, practice braking timing, and develop safety instincts—these are more reliable than any electronic devices.

From the perspective of traffic rules, running a yellow light is not considered running a red light because a red light mandates a stop while a yellow light serves only as a warning. In actual driving, if a vehicle has already crossed the stop line when the light turns yellow, proceeding is not a violation; however, failing to stop when possible may be counted as a traffic offense. Enforcement varies in strictness across different cities—Shanghai may impose heavier penalties. It is advisable to control your speed at intersections and observe light changes in advance. The core of safe driving lies in anticipating risks, obeying signals, reducing impatience, and maintaining a clear mind.

As a daily commuter, I've rushed through yellow lights and understand that pressure, but the risks are significant. Running a yellow light can easily lead to accidents, such as rear-end collisions from cars behind reacting too slowly or hitting pedestrians at crosswalks. In terms of time , leaving a few minutes earlier eliminates the fear of lights changing. Get into the habit of slowing down and stopping safely at yellow lights to ensure you have enough margin. When driving in the city, practice watching traffic lights from all directions—slow down immediately when you see a yellow light. Safety comes first, and it also saves you the hassle of fines.
