Double solid white lines on the road indicate that they separate lanes moving in the same direction. This marking visually signifies to drivers that changing lanes is prohibited in this area. It underscores the importance of maintaining position within your current lane for safety reasons, ensuring that drivers do not attempt to weave between lanes where doing so could create conflict with other vehicles.

Other options suggest different meanings that do not align with the true purpose of double solid white lines. For example, they do not indicate lanes moving in opposite directions, define a stop zone, or mark a pedestrian crossing—all of which are governed by different types of road markings or traffic controls.
