What should be noted when changing lanes for motor vehicles?

When changing lanes for motor vehicles, the following points should be noted: 1. Yield to vehicles traveling in the lane you intend to enter; 2. Avoid frequent lane changes; 3. Do not change more than two lanes at once; 4. When vehicles from both left and right lanes are changing to the same lane, the vehicle on the left should yield to the vehicle on the right. The method for changing lanes for motor vehicles is: 1. Observe and assess the traffic flow behind, beside, and in the lane you intend to enter; 2. After confirming safety, turn on the turn signal, check through the rearview mirror for any overtaking vehicles on both sides, and ensure there is a safe distance in the lane you plan to enter; 3. Steer smoothly into the desired lane and turn off the turn signal.

I see many beginners change lanes too hastily. The key is actually to look more and wait longer. After turning on the indicator, wait at least three seconds, during which you should repeatedly check the rearview mirror, paying special attention to any electric bikes in the blind spot on the right rear. Once, I almost hit a motorcycle when changing lanes in a hurry, but now I've learned my lesson: check the rearview mirror twice and turn my shoulder to confirm. Steer slowly and maintain a steady speed without sudden acceleration or deceleration. Be extra cautious around large trucks—they have many blind spots in their mirrors. It's better to drive an extra two kilometers to find a safer gap to change lanes. On highways, prepare early and never force your way at the exit—it's too dangerous.

My neighbor Lao Wang had a bad experience while changing lanes last time, and it all came down to not seeing clearly. I've developed a habit now: before changing lanes, I first glance at the rearview mirror, then quickly turn my head to check the blind spot—this move is actually exactly what the driving instructor taught during the license test. Especially on rainy days, you need to be extra careful; if the rearview mirror fogs up, wipe it immediately. Friends driving SUVs, take note: our higher vehicle height actually means larger blind spots. Recently, I found a good trick: check the position of the front wheels relative to the lane markings to judge if the car is aligned. Also, remember to turn off the turn signal promptly after changing lanes to avoid misleading the cars behind. Always maintain a safe distance!

The day before yesterday, while dropping my kid off at school, I encountered someone who kept changing lanes recklessly, which really ticked me off. Just remember these key points: using your turn signal is about communicating with surrounding vehicles—don’t assume you can turn immediately after flicking it on. When checking, pay attention to how the car behind reacts; if they suddenly accelerate, don’t force your way in. Be decisive when changing lanes—no hesitation—and maintaining a steady speed is crucial. At night on the overpass, watch out for the glare of headlights from cars behind you—sometimes it’s impossible to see the rearview mirror clearly. Over the weekend, I noticed a lot of heavy trucks on the national highway—keep your distance when changing lanes near them, as they can’t stop quickly.

As a ride-hailing driver, changing lanes hundreds of times a day. Here's some practical advice: Adjust your rearview mirror to just see your car door handle for optimal visibility. During rush hours, it's safest to change lanes in sync with traffic flow—going solo increases accident risks. If the navigation says to turn at the next exit, start moving to the outermost lane 1 km in advance. If the car behind honks at you during a lane change, don’t force it—chances are there’s a car in your blind spot. Once a passenger asked me about lane-changing techniques, I summed it up in eight words: Signal for three seconds, move your head first. Also, when changing lanes with the window down, turn off the music for three seconds to listen for any nearby vehicles.
