What does a broken white line signify on the road?

Answer: C — Lanes of traffic moving in the same direction, passing is permitted

A broken white line indicates that lanes of traffic are moving in the same direction and allows for passing. This means that a driver can change lanes when it is safe to do so. The presence of the broken line signals to drivers that they may maneuver between lanes, unlike a solid line, which would indicate that lane changes are discouraged or prohibited. Therefore, recognizing the meaning of a broken white line is crucial for safe driving as it facilitates smooth traffic flow while providing the flexibility to pass or switch lanes as needed.
