What is the difference between yellow dashed lines and white dashed lines?

[MacGenesis]

The difference between yellow dashed lines and white dashed lines lies in their appearance and function. The visual distinction between yellow dashed lines and white dashed lines is quite intuitive—one is a yellow dashed line, and the other is a white dashed line. Below is a detailed explanation of their different functions: Yellow lines: Yellow lines are used to separate lanes traveling in opposite directions and are typically painted in the center of the road. Whether it's a single or double yellow line, as long as it's solid, crossing is strictly prohibited. Under normal circumstances, you should not cross these lines. White lines: White lines are used to separate lanes traveling in the same direction. Dashed white lines indicate that lane changes are permitted, while solid white lines mean lane changes are not allowed, and you should not switch lanes arbitrarily.
