What does this lane signal mean for the lane under it?

  2. The lane is for oncoming traffic only
  3. The lane is for left turns from either direction, not for through travel
  4. The lane is closed to left turns
Show answer

Correct answer: The lane is for left turns from either direction, not for through travel

White two-way left-turn arrows mark a lane that traffic from both directions uses to turn left. Do not use it to go straight.
