Does Only Capturing the Front Count as Driving Against Traffic?

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.
