What does a solid white line on the road indicate?

A solid white line on the road indicates that no crossing or lane change is allowed. This type of line is commonly used to delineate lanes of traffic that are moving in the same direction. It serves as a visual barrier, signaling drivers that they should remain in their lane and not change positions. The intention behind a solid white line is to promote safety by preventing potential conflicts between vehicles, particularly in areas where changing lanes could lead to dangerous situations, such as near intersections or areas with heavy traffic.

The purpose of the other options is distinct. For example, a dashed white line would indicate that lane changes are permitted, while a suggested merging point might be marked with different signage. Pedestrian crossings are usually marked with specific symbols or lines that differ from solid white lines. Understanding these roadway markings is key to safe driving and compliance with traffic regulations.
