This sign means
- traffic merging ahead ✓
- lane narrows ahead
- intersection ahead
- concealed intersection ahead
Answer: A. traffic merging ahead
The sign means traffic merging ahead, so expect other vehicles joining the road you are on.
Why this is the answer
The handbook's warning sign list includes a sign for a road merging with another road, and the merging section explains what to do when lanes come together. When traffic joins or a lane ends ahead, you either change lanes or adjust your speed and wait for a safe gap, and if you are beside merging traffic you help by adjusting your speed or changing lanes. The handbook also warns against stopping in an acceleration lane or merging area. So the sign is alerting you to vehicles merging into your path.
Why the other answers are wrong
- B. lane narrows ahead — The warning sign list covers a narrow structure such as a bridge, not a lane that narrows, so this does not match the merge meaning the handbook gives.
- C. intersection ahead — The passages deal with merging traffic and lane endings here, and nothing in them describes a sign announcing an intersection ahead.
- D. concealed intersection ahead — A concealed or hidden intersection is not mentioned anywhere in these passages, so there is nothing to support that meaning.
Remember it
Think of it as a heads-up to look for a gap: whenever roads or lanes come together, someone has to blend in, and it may be you.
