There was an illegal lane change on the overhead display board, but I checked my license plate. What's going on here? Please answer!

The surveillance camera works 24 hours a day, and the license plate will be displayed on the screen when shooting on the spot. According to the traffic law, after a motor vehicle violates the rules, it can be inquired online or notified by SMS for 3 ~ 7 days, and the latest is 13 working days. If it is found and signed by the traffic police at the scene, the owner needs to go to the local traffic police team within 15 days after the violation. If it is left untreated for more than 15 days, a late payment fee of 3% shall be paid every day, but the amount of the late payment fee shall not exceed twice the original fine; If the photo is taken by electronic eye monitoring, the owner can check the violation records on the traffic website, and can go to the traffic police team in violation of the regulations within one month before the annual review of the motor vehicle, instead of within 15 days, but be careful not to exceed one scoring cycle of the driver's license as far as possible, so as to avoid the situation that one scoring cycle is not cleared in time, resulting in the cumulative deduction of 12 points in the next scoring week.
