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

[Leilani]

Here are the differences between yellow dashed lines and white dashed lines in the same direction lanes: Applicable environments: Yellow dashed lines are usually set on relatively narrow road surfaces; white dashed lines are usually set on relatively wide road surfaces. Distinction aspects: Yellow dashed lines are used to distinguish opposing traffic flows in different directions; white dashed lines are generally used to divide different lanes in the same direction. Operation aspects: Under safe conditions, yellow dashed lines allow crossing the line to borrow a lane for overtaking or making a U-turn; white dashed lines allow crossing the line for lane changes under safe conditions, but U-turns are not permitted.
