This sign means?

This sign means?
  1. Two-way traffic ahead
  2. Yield the lane to oncoming traffic
  3. The lane is only for right turns
  4. 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

Remember it

Remember it as "both sides left, no straight through."
