What does the solid white line at the side of the road indicate?

Explanation: The continuous white line shows the edge of the carriageway. It can be especially useful when visibility is restricted, such as at night or in bad weather. It's discontinued in some places; for example, at junctions, lay-bys, entrances or other openings.
