What does a broken white line signify?

A broken white line indicates that lane changes can be made safely. It denotes that the lanes on a highway or road are designated for traffic moving in the same direction and that drivers are permitted to switch lanes, provided it is safe to do so. This flexibility in changing lanes is essential for effective traffic flow, especially when merging or passing other vehicles.

In contrast, solid lines, whether white or colored, often signify restrictions on movement, such as prohibiting lane changes. Therefore, understanding the meaning of a broken white line is crucial for safe and informed driving practices.
