What does a solid white line between lanes indicate?

A solid white line between lanes serves as a visual cue that indicates a specific driving guideline. When a solid white line is present, it signifies that drivers should not change lanes in that area. This line is used to maintain a clear and consistent flow of traffic, ensuring safety by discouraging lane changes that could lead to accidents. It’s often found in situations where lane changes could pose risks, such as near intersections or areas where lanes converge.

In contrast, a dashed or broken white line would allow drivers to change lanes, while a solid white line strictly prohibits it. Therefore, recognizing the significance of solid white lines is crucial for safe driving practices, as they help to manage traffic patterns effectively and reduce the likelihood of collisions.
