How is lane-changing over the line determined?

When the front wheels of the vehicle press over the induction coil on the ground, the electronic eye captures the first photo. When the rear wheels of the vehicle press over the induction coil on the ground, the electronic device captures the second photo. When the vehicle passes through the intersection and presses over the induction coil on the opposite side of the ground, the electronic device captures the third photo.
As a seasoned driver with over a decade of experience, I often encounter lane-changing and line-crossing issues on highways. The rules are quite straightforward: according to traffic regulations, solid lines must never be crossed—doing so is a violation. Dashed lines can be crossed when changing lanes, but the entire lane-changing process must be completed within the dashed line area; you can't ride the line for too long. Enforcement primarily relies on electronic surveillance and on-site traffic police checks. Cameras capture your vehicle's trajectory—if your car crosses a solid line for more than a few seconds or covers too much of the line, the system automatically records a violation. The same applies when traffic police are present; they observe your wheel position and movement. I've learned this the hard way—once, I was fined 200 yuan for crossing a solid line while turning at an intersection. My advice is to signal early, check blind spots, and complete the lane change quickly once it's safe. Crossing lines isn't just about fines and points; it's also dangerous, as it can lead to side-swipe accidents, especially during rush hour. Regular practice with rearview and side mirrors can help avoid hesitation that leads to line-crossing.
