It is determined by capturing three photos with electronic cameras. The first photo shows the vehicle crossing the stop line at the intersection, including the red light signal and license plate number; the second photo shows the vehicle completely crossing the stop line, including the red light signal and license plate number; the third photo shows the vehicle continuing to move, mainly by comparing the position change of the vehicle in the second photo, including the red light signal and license plate number. Capturing these three photos can determine that the vehicle has run a red light. The act of running a red light is clearly defined in the "Road Traffic Safety Law." Article 26 states that traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to pass, and a yellow light serves as a warning. A red light is a traffic signal prohibiting passage, and if a vehicle passes through an intersection during a red light, it constitutes the traffic violation of running a red light. The following points can help avoid running a red light: First, look at the arrow light, then the circular light: Currently, there are two types of indicator lights: arrow traffic lights and circular indicator traffic lights. When arrow lights are present, first observe the arrow light and then the circular light to avoid running a red light. Note: When encountering a circular red light, right turns are allowed; when encountering an arrow signal light with a red right-turn arrow, right turns are prohibited, otherwise, it will be penalized as running a red light. Brake in time: When the red light turns on, do not let the front of the vehicle cross the stop line. If the front wheels accidentally cross, and the rear wheels follow, the electronic camera will capture it, resulting in a penalty for running a red light; if the front wheels have just crossed the stop line when the light turns red, passage through the intersection is prohibited, and you must wait for the green light. Check the green light countdown before proceeding: When the green light flashes, if there is a countdown, judge accordingly; if there is no countdown, and the vehicle is close to the intersection with high speed, you may proceed to avoid running a red light due to untimely braking; if the speed is slow and the vehicle is far from the intersection, brake immediately to avoid running a red light. Article 38 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states: When the green light is on, vehicles are permitted to pass, but turning vehicles must not hinder the passage of straight-moving vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to pass. When the red light is on, vehicles are prohibited from passing. At intersections without non-motor vehicle or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle signal lights. When the red light is on, right-turning vehicles may pass if they do not hinder the passage of other vehicles or pedestrians. Running a red light is not considered illegal under the following circumstances: Yielding to special vehicles: Yielding to ambulances, fire trucks, and other special vehicles. If captured by surveillance cameras while yielding to special vehicles, the act of running a red light will not be recorded during manual review. Even if recorded, you can apply for reconsideration at the traffic police department. Extreme weather: When visibility is so low that even electronic police cannot clearly see the traffic lights. The photos capturing the violation may be blurry, and if you accidentally run a red light, the traffic police will not impose penalties. Emergency situations: Transporting a critically ill patient to the hospital may involve running multiple red lights, and 12 points may not be enough. After delivering the patient, the citizen can provide proof from the hospital or the rescued person to the traffic police for verification. If confirmed, the violation record can be cleared. If possible, it is best to call an ambulance to avoid traffic accidents caused by running red lights. Traffic police direction: During peak hours, traffic police may temporarily direct traffic at important intersections. Drivers should follow the gestures of the traffic police. The traffic police department states that according to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," when the yellow light flashes at an intersection, vehicles that have already crossed the stop line may continue to pass. If the yellow light is already on and you still rush to pass, it will be considered running a red light if captured.
