What do solid white lines on the pavement indicate?

Solid white lines on the pavement serve a specific purpose in traffic control and road safety. They indicate that drivers should stay in their lane and not change lanes. This is particularly important in areas where lane changes could create safety hazards, such as near intersections or areas with heavy pedestrian traffic. The presence of a solid white line helps to maintain orderly traffic flow and reduces the potential for accidents by discouraging unsafe lane changes.

Other options might refer to different road markings. For instance, lane changes are often discouraged next to solid lines, while dashed lines indicate that lane changes are permitted. Additionally, solid white lines do not mark the left edge of the road, which is typically indicated by a solid or dashed yellow line, and they do not specifically indicate dangerous zones, although they can be found in areas where special caution is advised. Understanding the function of solid white lines is crucial for safe driving practices.
