What does a dashed white line in the center of the road indicate?

• A. Lane changes are prohibited at all times.
• B. You must stay in your lane.
• C. You may pass on the left if safe.
• D. Lane changes are allowed when safe.

Answer: (D)

A dashed white center line means you may change lanes when it’s safe to do so. It signals that crossing the line to pass or to move into an adjacent lane is allowed, as long you check for traffic, use your turn signal, and ensure there’s enough space before you move. The rule is about safety first: never cross if another vehicle is close, if you’re in a restricted area, or if the line becomes solid ahead. This is why the broader statement about lane changes being allowed when safe fits best. While it’s true you often pass on the left when on a two‑way road, the dashed line’s real implication is that changing lanes—whether to pass or to adjust your position for a turn or merge—is permitted when it’s safe. The other options describe situations that only apply to solid lines or imply you must stay in your lane, which the dashed line does not require.
