When the traffic light is red, if the front wheels of the vehicle have just crossed the stop line and the vehicle stops immediately without moving further, it will not be considered as running a red light. However, if the vehicle continues to proceed in violation of the rules, it will be deemed as running a red light, resulting in a penalty of 6 demerit points. If the vehicle completes crossing the line and continues to move until it is completely over the line before stopping, thereby affecting the passage of other vehicles and pedestrians, it will be penalized as over-the-line parking. According to Article 10 of the new traffic regulations, failing to stop at the stop line will result in a penalty of 1 demerit point. Article 38 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states the following for motor vehicle and non-motor vehicle signal lights: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles and pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. When the red light is on, vehicles are prohibited from proceeding. When the red light is on, right-turning vehicles may proceed provided they do not obstruct the passage of other vehicles and pedestrians. At intersections where there are no non-motor vehicle or pedestrian crossing signal lights, non-motor vehicles and pedestrians should follow the signals of the motor vehicle traffic lights. The new traffic regulations clearly define three necessary conditions for a vehicle to be considered as running a red light: The vehicle illegally crosses the stop line. The vehicle illegally enters the intersection. The vehicle illegally crosses the opposite stop line. Electronic police (traffic cameras) capture three complete video images to constitute a red light violation: an image of the vehicle at the moment of violation; an image of the vehicle's license plate; and a panoramic image. There are three scenarios regarding whether a vehicle is running a red light while driving: If the front wheels of the vehicle cross the stop line or both the front and rear wheels cross the stop line but the rear of the vehicle has not yet crossed the stop line and the vehicle stops immediately, traffic police will not penalize it as running a red light. However, the driver may be penalized for improper parking, resulting in 3 demerit points. If the front wheels of the vehicle cross the stop line, regardless of whether the entire vehicle has completely crossed the stop line, and the vehicle stops and then reverses back, being captured by traffic cameras with two complete movement images processed, it will be considered as running a red light, resulting in a penalty of 6 demerit points and a fine. If the entire vehicle completely crosses the stop line and stops or continues to proceed, and within one red light cycle, the electronic cameras capture the three complete images constituting a red light violation, regardless of whether the vehicle proceeds to the intersection or crosses the opposite stop line, it will be considered as running a red light, resulting in a penalty of 6 demerit points and a fine.

Once when I was driving at an intersection, I braked a bit late and my car crossed the stop line but came to a halt—this is called over-line stopping. The police said it wasn't serious, just a fine as a warning with no points deducted. The key thing was the car wasn't moving, just in the wrong position which could easily block pedestrians. Running a red light is completely different. A friend of mine did it before—he drove straight through a red light and ended up colliding with an electric bike, resulting in hefty hospital bills. The difference lies in the fact that the former involves stopping and waiting for the green light, while the latter is a complete disregard for the rules when crossing the intersection. Over-line stopping often happens due to slow reactions or slippery roads, whereas running red lights is usually due to rushing to save time. For safety, I've developed the habit of making decisive decisions at yellow lights—slowing down and preparing to stop to avoid over-line stopping, especially on rainy days when roads are slippery, being extra careful to avoid any violations. Overall, one is a positional error but stopping, while the other is a dynamic violation risking forward movement—the latter is far, far more dangerous.

As a road safety advocate, I believe the core difference lies in risk. Stopping over the line leaves the vehicle outside the intersection, potentially obstructing pedestrian crossings or causing abrupt braking by following vehicles—a relatively minor but still noteworthy risk. Running a red light, however, involves blatantly violating traffic signals and entering opposing traffic flow, directly endangering cross-traffic vehicles, pedestrians, and potentially causing fatal collisions. Common causes differ: line-crossing often stems from distraction or misjudgment, while red-light running typically reflects reckless intent. Statistically, red-light violations trigger higher accident rates and incur stiffer penalties. My recommendations: maintain driving focus, anticipate signal changes early, install blind-spot monitoring aids to prevent errors, and exercise extra caution in school zones. Ultimately, the former is a static minor issue, while the latter constitutes a dynamic major hazard.

From the perspective of traffic regulations, over-line stopping refers to coming to a halt beyond the stop line during a red light while the vehicle remains stationary; running a red light involves continuing to drive through the intersection despite the red signal. The former is a lesser violation, often resulting in smaller fines, while the latter is more severe, typically incurring point deductions and heavier penalties due to its higher accident risk. For instance, surveillance systems frequently capture instances of red-light running. Over-line stopping may occur due to delayed braking, whereas running a red light is a more deliberate and aggressive act. Drivers should memorize stop line positions and control their speed to avoid both scenarios, ensuring road safety.
