This sign means?

- Two-way traffic ahead
- Yield the lane to oncoming traffic
- The lane is only for right turns
- Vehicles from both directions must turn left, no through traffic allowed ✓
Answer: D. Vehicles from both directions must turn left, no through traffic allowed
The sign means vehicles coming from both directions must turn left, and no traffic may continue straight through.
Why this is the answer
The handbook describes lane-use signs as showing which lanes may be used to turn or go straight, and it says you must follow the direction indicated if you are in a designated lane. The line matching this sign states that traffic from both directions must turn left and through traffic is not allowed. So the sign directs left turns from each side; it does not warn of two-way traffic ahead or set the lane aside only for right turns.
Why the other answers are wrong
- A. Two-way traffic ahead — A two-way traffic warning tells drivers about traffic coming toward them, but this sign instead directs both directions to make left turns and forbids through traffic.
- B. Yield the lane to oncoming traffic — The sign does not tell one direction to yield the lane to oncoming traffic; it directs vehicles from both directions to turn left.
- C. The lane is only for right turns — The sign is not limited to right turns; it directs left turns from both directions.
Remember it
Remember it as "both sides left, no straight through."
