Difference Between Single and Double Solid Lines

[ElenaDella]

The differences between double solid lines and single solid lines: 1. Number of lanes differs: A single solid line indicates there is only one lane in the same direction; double solid lines indicate there are two or more lanes in the same direction. 2. Width varies: Roads with single solid lines are generally not very wide; roads with double yellow solid lines are usually more spacious. 3. Solid and dashed lines differ: Some sections of single yellow lines have dashed lines, indicating that vehicles are allowed to make left turns or U-turns in these areas; however, double yellow lines are different, with some sections having a dashed line on one side and a solid line on the other. Introduction to road markings: 1. Yellow dashed lines can serve as dividing lines or centerlines; when used as dividing lines, lane changes are permitted. 2. Lane dividing lines are white dashed lines, used to separate traffic flows moving in the same direction, and are marked on the dividing lines of lanes moving in the same direction.
