What does a broken yellow line indicate?

Answer: B — Separation of lanes moving in opposite directions

A broken yellow line serves as an important road marking indicating the separation of lanes moving in opposite directions. This means that drivers are allowed to cross the broken line to pass another vehicle, provided it is safe to do so. The presence of the broken line signifies that the road is designed to accommodate two-way traffic, allowing for the possibility of overtaking or changing lanes with caution. Understanding this traffic marking is vital for safe driving, as it helps drivers navigate situations where they may need to pass slower vehicles. The other options do not accurately describe the function of a broken yellow line, as they refer to different scenarios relating to traffic flow, speed, or parking regulations.
