This sign means
- right lane ends ahead ✓
- merge right ahead
- narrow structure ahead
- two-way traffic ahead
Answer: A. right lane ends ahead
This sign means the right lane ends ahead, so traffic in that lane must merge into the lane beside it.
Why this is the answer
The handbook's merging section says this sign tells you the right lane will end soon. If you are the driver in that lane, you need to change lanes: adjust your speed within the speed limit and wait for a safe gap. If you are in the lane beside it, the book asks you to help the merging traffic by adjusting your speed or changing lanes. The warning signs list gives a separate entry for a road that merges with another road, where the added lane is on the right, so the lane-ending meaning is its own sign.
Why the other answers are wrong
- B. merge right ahead — The handbook's warning sign for a road merging with another road describes an added lane to the right ahead, which is the opposite of a lane being taken away.
- C. narrow structure ahead — A narrow structure ahead is listed as its own separate warning sign, often marking a bridge, so it does not describe a lane ending.
- D. two-way traffic ahead — None of the passages describe a two-way traffic warning sign, so that meaning is not supported here.
Remember it
Read it as a lane-closing notice: the driving space on the right is about to disappear, so plan your move into the next lane early.
