What does a dashed line signify?

Answer: B — Lane changing is allowed

A dashed line on the road signifies that lane changing is allowed. This type of marking indicates to drivers that they can safely move from one lane to another, provided that it's safe to do so. When you see a dashed line, it means that the lane is not designated for a specific purpose and that drivers have the flexibility to change lanes as needed, keeping in mind the surrounding traffic conditions. In contrast, a solid line would indicate that lane changes are restricted or prohibited in that area, emphasizing the importance of following lane markings for safety. Understanding this is crucial for ensuring smooth traffic flow and avoiding potential collisions.
