What does a broken white line signify on the road?

Answer: B — That passing is allowed

A broken white line signifies that passing is allowed, providing drivers with the flexibility to change lanes when it is safe to do so. This marking indicates that while lanes are separate, vehicles may move between them, and it’s particularly useful for facilitating traffic flow and allowing for overtaking slower vehicles. In contrast, solid lines (white or yellow) indicate lane restrictions, and signs or other road markings alert drivers to conditions that may require them to maintain their position or take caution. The presence of a broken white line also suggests that other vehicles may be attempting to change lanes, making it important for drivers to be vigilant and aware of their surroundings when driving near such markings.
