Which pavement marking indicates reversible lanes?

• A. Solid white lines.
• B. Solid yellow lines.
• C. Double-dashed yellow lines.
• D. Dashed white lines.

Answer: (C)

Reversible lanes change direction to adapt to traffic flow, and the pavement marking that signals this is double-dashed yellow lines. The two yellow lines are dashed, indicating that the center boundary can change with the traffic controls, guiding which direction the lane is currently allowed to carry. This marking tells drivers that the lane assignment can switch at certain times and that you should follow the posted signs and signals.

Solid white lines show boundaries where lane changes aren’t allowed and are not used to indicate reversibility. A solid yellow line marks no passing into opposing traffic, not a reversible lane. Dashed white lines indicate normal lane changes within the same direction, not a lane whose direction can reverse.
