What does a dashed white line between lanes signify?

Answer: B — Lanes may be changed

A dashed white line between lanes signifies that lane changes are permitted. This means that drivers can safely switch between lanes as long as it is clear and safe to do so. The dashed line acts as a guide, indicating that the lanes are designed for potential movement among vehicles, thereby promoting flexibility in navigation. In contrast, a solid line would indicate that lane changes are not allowed. Understanding this marking is crucial for maintaining safety and ensuring effective road utilization, as it helps drivers make informed decisions about when and where to change lanes.
