Normal lane changes will not result in point deductions, but changing lanes in areas where it is prohibited will lead to point deductions. The precautions for changing lanes while driving and the behaviors constituting illegal lane changes are as follows: Precautions for changing lanes while driving: Before changing lanes, you must first signal to inform the vehicles behind of your intended direction. Many drivers on the road neglect the habit of signaling before changing lanes, which can easily lead to collisions. Observe the road conditions ahead and in the rearview mirror, and maintain a safe distance. The most appropriate time to change lanes is when the vehicle behind is fully visible in the rearview mirror and occupies less than a quarter of the space. When changing lanes, turn the steering wheel gently and gradually, aiming for the side front of the vehicle. It's best to keep the angle between the vehicle and the lane markings as small as possible. Change lanes quickly, maintaining the original speed or slightly accelerating. Do not change multiple lanes at once; instead, change one lane at a time, gradually merging into the inner lane. Behaviors constituting illegal lane changes: Making a sudden U-turn violates the principle of straight-line priority. Changing lanes in a solid-line lane marked with a specific direction and crossing the solid white line. Changing lanes while turning on the signal light, thereby affecting the vehicle behind. Being in a left-turn lane waiting at a red light, then accelerating straight through when the straight light turns green, despite the requirement to turn left. Crossing double yellow lines without barriers to overtake, typically occurring during traffic congestion when one direction is congested and the opposite lane has fewer vehicles, leading to impatience.

I was also quite worried about this when I first started driving. Changing lanes itself doesn't incur penalty points, but improper operation can really get you fined. I've personally seen someone cutting in line without using turn signals and getting caught on camera. There are two key points: first, you must activate your turn signal at least three seconds in advance - you can't signal and turn simultaneously; second, you mustn't cross solid lines when changing lanes - whether white or yellow solid lines, crossing them means an instant 3-point deduction. Lane changes in rainy weather require extra caution as fogged side mirrors can lead to misjudgment. Oh, and consecutively changing across two lanes is particularly dangerous - it might even be considered reckless driving. Last week, my colleague on the highway hesitated too long when giving way to a truck, ended up being honked at by the car behind - actually, staying calm is safer.

A veteran driver with ten years of experience tells you that whether you get penalized for changing lanes depends entirely on the details. I learned this the hard way once when I thought there was enough distance based on the rearview mirror, but got rear-ended immediately after changing lanes. The police arrived and ruled it was entirely my fault. Now I’ve wised up—I check the rearview mirror twice before turning the wheel. Rush hour in the city is the most annoying, especially when someone forces their way in with their turn signal on. This kind of tailgating will definitely cost you 3 points. Late-night driving can make you careless—once, while signaling to change lanes, the car on my left suddenly accelerated, nearly causing a scrape. My advice: before changing lanes, besides checking the mirror, it’s best to glance over your shoulder to check blind spots. Electric scooters often dart out from dead angles.

The passenger seat offers the clearest view, and getting caught for illegal lane changes feels truly unfair. Once, while riding a ride-hailing car, the driver suddenly received a call during a lane change. Steering with one hand, he crossed the solid line and was penalized with 1 demerit point and a 200-yuan fine. The scariest are those who change lanes abruptly without signaling—the sound of the car behind slamming on the brakes is audible even through the glass. Before changing lanes, besides checking the rearview mirror, it's best to blink twice to confirm the blind spot—a down-to-earth trick my dad taught truck drivers. On rainy days, the spray kicked up by the car ahead can completely obscure the rearview mirror during a lane change. In such cases, it's better to miss the exit than force a lane change.

When teaching defensive driving, I always emphasize: only change lanes after getting a nod from the following car to ensure safety. Traffic regulations clearly state that you must not affect vehicles traveling normally in the lane, meaning if the following car brakes, you've violated the rules. Some trainees get penalized for crossing solid lines on bridges and feel unjustified, but surveillance footage shows they could have merged 500 meters earlier. Crossing solid lines in tunnels is penalized most strictly—accidents there often lead to chain collisions. I recommend developing a three-step lane-changing habit: check the distance in the rearview mirror, turn on the signal and count to three silently, then accelerate into the lane. Many people forget that consecutive lane changes in the highway's passing lane result in an immediate 3-point deduction.

Every day, what I see most in surveillance captures is solid line lane changes, especially at the highway exit guide lines. Many drivers, upon missing the exit, abruptly steer, with their tires pressing on the triangular zone, resulting in a capture and a one-point deduction. During the morning rush hour on the elevated roads, it's even more extreme—some drive straddling the line for two kilometers, and the electronic police can capture seven or eight photos. A reminder to everyone: even when changing lanes in the dashed line area, pay attention to the distance between vehicles. Cutting in front of another car by closing the gap and then changing lanes is considered forced merging, which under new regulations results in a three-point deduction if it causes an accident. When training students, I've noticed that the angle of the rearview mirror is crucial. Adjust it to a position where you can see a small portion of your own car body to accurately judge distances.
