What are the precautions for changing lanes?

Here are the precautions for changing lanes: 1. Changing lanes to the left: You can use 3rd gear or higher to change lanes. Generally, 3rd gear is suitable for speeds of 20-40 km/h, 4th gear for 40-60 km/h, and 5th gear for speeds above 60 km/h. Also, choose the appropriate gear based on the speed requirements of the left lane. For example, if the left lane requires a speed of 40-60 km/h, you can use 4th gear to change lanes. 2. Changing lanes to the right: When you need to change lanes to the right, you can first maintain your current gear and gradually merge into the right lane. After fully entering the lane, you can downshift by one gear.

I've been driving for over a decade, and lane changing requires special attention. First, always turn on the turn signal a few seconds in advance to give drivers behind time to anticipate, avoiding sudden surprises. Then, check the rearview mirror for any vehicles, but never rely solely on it—turning your head to check blind spots is crucial. Motorcycles or bicycles can hide in those blind zones; I once nearly hit an electric scooter because I didn't look. For distance, maintain at least a two-second gap on highways before changing lanes. In city traffic jams, don't rush—avoid cutting in or jerking the steering wheel, as it can easily cause rear-end collisions. In bad weather like heavy rain, slow down and observe more due to slippery roads, making lane changes gentler. Develop good habits: avoid distractions like using your phone while driving.

During my daily commute, I have to change lanes several times. Here are some key points I've summarized: Always use your turn signal before changing lanes to alert the cars behind you—don't be lazy and cut in directly. Then, carefully check your rearview mirror and turn your head to confirm the blind spot—don’t just glance and swerve. Last time I missed a quick look and almost rear-ended a van, which scared me into a cold sweat. Make sure there's enough safe distance, and don’t squeeze in front of another car. On highways, gauge the traffic speed and choose a gap to merge smoothly. In low visibility conditions like rain or fog, I signal longer and double-check before moving. Remember, never rush to change lanes on curves or at intersections—it's way too dangerous!

Safe lane changing is fundamental, and I double my caution when driving with family. Signal early, check mirrors, and glance over your shoulder to ensure blind spots are clear; don't wait until the car behind is too close—leave ample buffer space. Avoid changing lanes during hard braking, as it increases the risk of losing control or scraping. In poor weather like snow, slow down and observe longer before deciding. Beginners can practice in open areas to perfect the maneuver. The key is anticipating others' reactions—once, I nearly caused an accident by not noticing a car in my left blind spot, so now I always take extra seconds to confirm. Stay vigilant to prevent accidents.
