A broken white line with a white arrow to the left or right indicates your lane is ending, or about to merge with another lane.

• A. Broken white line with a white arrow to the left or right
• B. Broken white line
• C. Single solid white line
• D. Center line

Answer: (A)

Understanding lane endings and merging cues from pavement markings helps you plan your moves safely. A broken white line with a white arrow pointing left or right signals that the lane you’re in is ending and you should prepare to merge into the adjacent lane in the direction of the arrow. This cue tells you to look for a safe gap, signal, and merge smoothly rather than waiting until the last moment. A plain broken white line means you may change lanes if it’s safe, but it doesn’t warn of an upcoming lane end. A single solid white line indicates you should not cross in most situations, and a center line separates traffic going in opposite directions and can be solid or dashed depending on passing rules; those markings don’t indicate a lane ending like the arrow marking does. When you see this arrow-marked line, start checking ahead for a merge opportunity so you can blend in safely.
