What does a dashed line on a road signify?

A dashed line on a road indicates that you may change lanes if it is safe to do so. This type of line is used to signify that drivers have the option to move from one lane to another, provided that they have checked their mirrors and blind spots and ensured that it is clear to make the lane change. The presence of the dashed line signals flexibility for drivers, distinguishing it from solid lines, which would indicate restrictions on changing lanes.

In contrast, solid lines are used in various contexts to emphasize the necessity of staying within one's lane or that lane changes are prohibited, depending on the specific road markings. Additionally, a dashed line does not relate to the directionality of the road, which is what would be indicated by separate signs or markings specific to one-way streets. Therefore, understanding the meaning of dashed lines is crucial for safe driving and lane management on the road.
