Is it illegal to change lanes over dashed lines?

[FernandoMarie]

Whether changing lanes over dashed lines constitutes a violation depends on the following situations: 1. When it disrupts road order: Changing lanes over dashed lines is not considered a violation. 2. Continuous lane changes: Even if performed over dashed lines, it is a violation. Drivers must proceed in order and should not frequently change lanes; they must not change two or more lanes at once. 3. Forcing lane changes during traffic congestion: When encountering queued or slow-moving vehicles ahead, drivers must not borrow lanes to overtake or occupy the opposite lane, nor should they cut in line. 4. Failing to signal or signaling for less than three seconds when changing lanes: When turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn, drivers must activate the left turn signal in advance; when turning right, changing lanes to the right, returning to the original lane after overtaking, or pulling over to the roadside, drivers must activate the right turn signal in advance.
