Which line marking indicates you may pass if it is safe to do so?

• A. Solid yellow line
• B. Dashed yellow line
• C. Solid white line
• D. Double solid yellow line

Answer: (B)

Passing is permitted when the center line is dashed. A dashed yellow line signals that you may pass if the lane ahead is clear and it’s safe to do so, giving you enough time and distance to complete the maneuver without cutting in front of another vehicle. By contrast, a solid yellow line means no passing, a double solid yellow line means no passing in either direction, and a solid white line marks the edge of the roadway or a boundary where changing lanes or crossing is discouraged. So, the dashed yellow line is the marking that indicates you may pass if it’s safe.
