What does a solid white line indicate?

A solid white line serves as a visual cue that lane changes are not permitted. This line is commonly used on the road to signify that drivers should remain in their current lane and avoid crossing over it. The purpose of this rule is to enhance safety by discouraging maneuvers that could lead to conflicts between vehicles, particularly in areas where it may be hazardous to change lanes, such as near intersections, pedestrian crossings, or in areas with high traffic.

In contrast, lane changes are generally encouraged or permitted when there are broken white lines, as these indicate that it is safe to maneuver between lanes. Understanding the significance of a solid white line helps drivers make informed decisions while navigating roadways, promoting smoother traffic flow and reducing the risk of accidents.
