What does the solid white line in the middle of the road mean?

The solid white line in the middle of the road is the dividing line between traffic lanes in the same direction. Set up to distinguish different lanes.

White solid lines cannot be pressed. If there is a dotted line between two lanes in the same direction, you can change lanes. If there is a solid line, lane changing is prohibited.

The white solid line on the side of the road is a sign used to divide motorized lanes and non-motorized lanes, and is also equivalent to the boundary line of motorized lanes. There is no necessary connection between the white solid line and the ability to park. Seeing a white solid line on the side of the road does not mean that parking is not allowed here. You need to judge whether parking is possible on this road section based on other signs or marking lines.
