Changing Lanes: To the Left or Right?

[Lukas]

When changing lanes from the fast lane, move to the right; when changing lanes from the slow lane, move to the left. Here are some additional details: 1. Lane-changing techniques: Before changing lanes from the slow lane, quickly turn on the left turn signal, observe the traffic behind you to ensure safety, and after three seconds of signaling, steer left to smoothly enter the left lane; when changing lanes from the fast lane, turn on the right turn signal, check the right rearview mirror for safety, and after three seconds of signaling, smoothly merge into the travel lane; if the turn signal does not automatically cancel, remember to turn it off manually. 2. Precautions: If space allows, accelerate to a speed faster than the vehicle behind you in the target lane; if there isn't enough space to accelerate, try to minimize the speed difference between your vehicle and the one behind you. Always signal in advance—don't turn the steering wheel and activate the turn signal simultaneously—to give others enough time to react.
