What is the meaning of a solid white line on the road?

A solid white line on the road serves the specific purpose of acting as a lane-divider that should not be crossed. This road marking indicates that lane changes are discouraged and that drivers should remain within their current lane. The presence of a solid white line emphasizes safety by guiding traffic and preventing maneuvers that could lead to collisions, particularly in areas where the danger of weaving between lanes is higher, such as near intersections or in zones with heavy pedestrian traffic.

This differs from a dashed white line, which indicates that changing lanes is permitted. Therefore, understanding the significance of a solid white line is crucial for safe driving practices. It reinforces the rules of the road and helps maintain orderly traffic flow.
