What does a white line between lanes signify?

Answer: B — It indicates that you may cross between lanes if it is safe to do so

A white line between lanes indicates that drivers are allowed to change lanes if it is safe to do so. This is an important aspect of road markings that helps facilitate the flow of traffic. When you see a white line separating lanes, it serves as a guide rather than a strict barrier, meaning you can switch lanes to maneuver, provided it is done safely and without interfering with other vehicles. In contrast, a solid yellow line typically signifies that passing is not allowed, while a dashed yellow line may indicate that passing is permitted. Therefore, understanding the significance of these lines helps ensure safe driving practices while adhering to traffic regulations.
