Generally, driving against traffic requires capturing both the front and rear license plate numbers in two images to be considered a traffic violation. Principle of Capturing Driving Against Traffic: Typically, there are two vehicle detection loop sensors installed at the front and rear of the motor vehicle lane—Sensor 1 and Sensor 2. Normally, vehicles should pass Sensor 1 first, followed by Sensor 2, which does not trigger the electronic police to take photos. If a vehicle is driving against traffic, it will pass Sensor 2 first, then Sensor 1, reversing the normal sequence, which triggers the electronic police to capture images. Determination of Driving Against Traffic: On roads with solid dividing lines (double solid lines or single solid lines), vehicles must not cross the line under any circumstances. If a motor vehicle enters the opposite lane, it is considered driving against traffic. On roads with dashed dividing lines, vehicles may overtake by borrowing the opposite lane if it is safe, but in the event of an accident, the borrowing vehicle will be deemed to be driving against traffic. On roads with one-way signs, any motor vehicle entering is considered to be driving against traffic.

As a car technology enthusiast, I often pay attention to traffic safety equipment. Whether a wrong-way driver can be identified as a violation when captured from the front depends on the type and functionality of the camera. Ordinary fixed cameras might only capture the front of the car and the license plate, but proving wrong-way driving on a one-way road requires complete evidence of the vehicle's movement direction. A mere front-facing photo might sometimes miss the reverse driving trajectory, especially at night or in blurry situations, making it harder to determine. However, modern smart cameras can make a comprehensive judgment through time difference and path analysis, such as combining changes in license plate position, but there is still room for debate. I remember discussing a similar topic last time—installing multi-angle surveillance at highway entrances is more reliable to avoid the risk of misjudgment. If you encounter such a situation, it's best to review the footage or consult the relevant department. Safe driving is always the top priority.

I drive to and from work every day and think that only capturing the front of the car when going the wrong way may not be solid evidence, as the coverage of road cameras is limited. When you're driving in the wrong direction, the front of your car facing the camera doesn't necessarily prove a violation unless the background shows you came from the opposite side. Once, I accidentally turned into a one-way street and was photographed from the front, but I didn't receive a ticket, possibly due to insufficient evidence. However, this shouldn't be an excuse to try going the wrong way—the risk of violation is too high. It's important to develop the habit of checking road signs and arrow directions carefully. If you mistakenly enter a wrong-way lane, correct it promptly. Equip your car with a dashcam to record a full view, protecting your rights and giving you peace of mind.

I understand traffic regulations. According to traffic laws, determining a wrong-way driving violation requires clear evidence such as the vehicle's position and direction of travel. Simply capturing the front of the car without showing the entire vehicle on the wrong path makes it difficult to establish a case. When camera technology is insufficient or obstructed, it may miss key details, which is why many drivers successfully appeal. Remember, in some city systems, front-end photos need to be analyzed in conjunction with road conditions. To avoid trouble, it's best to drive properly and follow the rules.
