What do two solid white lines indicate?

Two solid white lines indicate that lane changes are not permitted. This is particularly important for maintaining safety and order on the roadway. When you see solid white lines, they serve as a clear visual barrier that indicates drivers should remain in their designated lanes. The use of solid lines is intended to prevent lane changes in areas where it may be dangerous or where other traffic conditions do not allow for safe maneuvering, such as in areas near intersections or merging sections.

In contrast, other road markings, such as broken lines, allow for lane changes, and other types of solid lines may have different meanings related to specific vehicle use or restrictions. Understanding these markings is crucial for safe driving practices and adhering to road regulations.
