On two-lane highways, when are you allowed to pass another vehicle?

Passing another vehicle on two-lane highways is permitted when there is a dashed yellow line on your side of the center dividing line. This dashed line indicates that you are in a position where it is safe to pass, as it marks the boundary between lanes where overtaking is allowed. It is essential for drivers to recognize this signaling because it signifies that the road conditions enable safe passing without risking collisions with oncoming traffic.

The other options present conditions that generally do not allow for safe or legal passing. A solid yellow line means no passing is allowed, as it indicates that it may be dangerous to overtake another vehicle due to limited visibility or curves in the roadway. Restricting passing only to daylight hours could imply that it is not permitted after dark, which is not typically the sole condition for passing for safety regulations; rather, visibility and road conditions govern that decision. Additionally, while it may be tempting to pass when a vehicle is traveling below the speed limit, this does not guarantee that the action is safe or legal, especially if other traffic or road conditions do not permit it. Thus, understanding the significance of the dashed yellow line is crucial for safe driving practices on two-lane highways.
