What is the Central Yellow Road Marking?

[ManuelMarie]

Yellow grid lines on the road indicate that all vehicles are strictly prohibited from stopping for a long time or temporarily to prevent traffic congestion. The following is an introduction to the content related to crossing the lines: 1. Solid lines: Whether it is a single yellow line or a double yellow line, as long as it is a solid line, crossing is strictly prohibited, such as overtaking, turning, or making a U-turn. There should be no crossing of the lines under normal driving conditions. 2. Dotted lines: Whether it is a single yellow line or a double yellow line, as long as it is a dotted line, overtaking or making a U-turn is allowed under safe conditions. Single yellow lines are generally used on roads with four or fewer lanes (including bicycle lanes) in both directions, while double yellow lines are generally used on wider roads. At a red traffic light, a U-turn can be made 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 for U-turns, it means that U-turns are allowed at the intersection. Unlike left-turning vehicles, U-turning vehicles can make a U-turn at a red light as long as it does not affect the normal passage of other vehicles.
