Can Running a Red Light Behind a Large Vehicle Be Captured by Cameras?

[StephanieLynn]

Running a red light behind a large vehicle can be captured by cameras. Penalty points for running a red light: According to Article 2, Clause 1, Subclause 2 of the "Scoring Standards for Road Traffic Safety Violations," driving a motor vehicle in violation of traffic signal lights will result in a deduction of 6 points. Article 3, Clause 1, Subclause 8 states that driving a motor vehicle in violation of prohibitory signs or markings will result in a deduction of 3 points. How to check for red light violations: You can check for red light violations through the "Traffic Management 12123" app. After opening the app, log in using your ID card, then find and click on the "Violation Handling" option. Under violation handling, you can view the current status of your vehicle. If there are any violations, the specific details will be displayed. You can also check at the service terminals in the offices of the traffic police departments in various districts and counties. Alternatively, visit the official website of the local public security bureau's traffic management bureau, locate the vehicle violation query section, enter your license plate number and vehicle engine number, and click "Query."

A traffic police friend of mine told me that it's almost impossible to avoid getting caught running a red light when following a large vehicle. Nowadays, the electronic eyes at intersections are becoming increasingly advanced, capturing images from multiple angles. Panoramic cameras record the entire intersection's dynamics, while close-up shots specifically target license plates. Even if the vehicle in front is a truck, the system will continuously take three key photos: your vehicle's rear passing the stop line while the light is red, your vehicle moving to the middle of the road, and completely crossing the intersection. As long as all three photos are present, the system automatically counts it as a violation. Last time, when Old Li was driving my car and encountered this situation, he deliberately appealed, but the staff at the counter pulled up the surveillance footage to show him—clearly capturing the moment the wheels crossed the line as the light turned red. In the end, he obediently paid the fine. Honestly, you really need to keep enough distance when following large vehicles; if you can't see the traffic light, don't stubbornly follow.

Let me share an embarrassing incident I experienced last month. I was following a bus downhill, accelerating when it did. Suddenly, it passed through just as the light turned red, and I only realized I was halfway over the stop line. I thought I was done for, and sure enough, I received a notification message later. Upon checking the record, the camera captured the scene from an overhead angle, clearly showing a gap between my car's front and the bus's rear, with the red light visibly illuminated in the frame. Nowadays, electronic traffic enforcement uses high-definition multi-angle coordination—wide-angle lenses capture positioning, while telephoto lenses focus on license plates. A traffic police system insider told me the system employs algorithms to automatically filter out obstructions, primarily checking whether the following vehicle crosses the line during a red light.

I've worked on traffic monitoring equipment, and this issue depends on the specific hardware configuration at the intersection. Nowadays, newly installed systems use a combination of fisheye panoramic cameras and license plate close-up camera units. The fisheye lens captures the positional relationships of all vehicles at the intersection - even if there's a large truck in front, your car several meters behind it can still be clearly seen. The close-up lens with license plate recognition means that as soon as the vehicle in front moves and reveals your position while the red light is still active, you'll 100% be recorded as part of a complete traffic violation evidence chain. Some older equipment might occasionally miss shots, but after upgrades in recent years, there are basically no blind spots left.

Back when I was a novice driver, I got tricked once too. The instructor kept emphasizing watching traffic lights, but during a heavy downpour, I followed a dump truck too closely and only realized I'd run a red light after crossing the line. I anxiously waited for two weeks until the penalty SMS arrived. When reviewing the surveillance footage at the station, the red light stood out clearly through the rain - my rear bumper crossed while there were still two seconds left. The officer said they handle thousands of such appeals annually, with nearly all failing. They adhere to three non-negotiable principles: drivers must maintain proper observation, following distance should allow signal visibility, and crossing the stop line after red light activation constitutes violation. Now when following large vehicles, I deliberately leave an extra half-car length, even if it means getting honked at by drivers behind.

Last time at the DMV, I saw a lady arguing with a surveillance screenshot, saying she shouldn't be fined because a large vehicle blocked her view. The staff then pulled up three consecutive photos: the first showed her front wheels crossing the line while the light was red, the second showed her car in the middle of the intersection, and the third showed her completely passing through, with the background light still red. I chimed in, asking if surveillance is this advanced now? The staff explained while operating: the system automatically identifies the leading vehicle as a moving obstacle and separately tracks and analyzes the following vehicle's trajectory. The new equipment captures over ten photos per second, using license plate positioning and fill light for snapshots. Even if the leading vehicle is a container truck, as long as the following vehicle's position triggers the red light sensor zone, it will be recorded.
