What is the function of the yellow dividing line in the middle of the road?

[VanKylie]

The yellow dividing line in the middle of the road serves to separate opposing traffic flows. Below is a related introduction to the yellow dividing line: 1. Solid yellow line: Whether it is a single or double yellow line, as long as it is solid, crossing is strictly prohibited, such as overtaking, turning, or making a U-turn. Under normal driving conditions, you should not cross the line. 2. Dashed yellow line: Whether it is a single or double yellow line, as long as it is dashed, you can overtake or make a U-turn when it is safe to do so. A single yellow line is generally used on roads with four or fewer lanes (including bicycle lanes), while a double yellow line is typically used on wider roads. At an intersection with a red light, a U-turn is allowed on a solid line only when the left-turn signal is green. If there is no dedicated U-turn signal light at the intersection and no prohibition sign is set up, it means U-turns are permitted at the intersection. Unlike left-turning vehicles, U-turning vehicles can proceed at a red light, provided they do not interfere with the normal passage of other vehicles.
