What are the penalties for changing lanes that affect other vehicles?

[MacCharlotte]

Changing lanes in a way that affects other vehicles may result in a warning or a fine. According to regulations, on roads with two or more motor vehicle lanes in the same direction, the vehicle changing lanes must not affect the normal driving of vehicles in the related lanes. When changing lanes, observe through the rearview mirror whether there are vehicles overtaking on both sides of the road, and confirm whether there is a safe distance in the lane you intend to enter. Without hindering the normal driving of vehicles in that lane, smoothly steer into the desired lane and then turn off the turn signal. When changing lanes at an intersection, observe the road traffic signs and markings in advance, choose the driving lane according to the direction you need to go, and enter the guiding lane before the solid line area in the direction of the guiding arrow.
