What does a dashed yellow line in the center of the road signify?

Answer: C — Passing is allowed if safe

A dashed yellow line in the center of the road indicates that passing is allowed if it is safe to do so. This marking signifies that traffic traveling in opposite directions is separated, and drivers have the option to overtake a vehicle in their lane. However, drivers must ensure that it is safe and legal to pass, meaning they should have a clear view of oncoming traffic and a sufficient distance to complete the maneuver without endangering themselves or others. The presence of the dashed line emphasizes the importance of driver judgment and caution while navigating these situations. Drivers should check for oncoming vehicles and consider road conditions before choosing to pass.
