Orange diamond sign with the black words RIGHT LANE CLOSED AHEAD

What does this sign tell you?

  1. The right lane is only for buses
  2. The right lane ends at the next exit
  3. The right lane is closed ahead, so merge left
  4. The right lane is for slow vehicles
Show answer

Correct answer: The right lane is closed ahead, so merge left

Lane closed signs are used before the point where a through lane is closed. Move out of the closed lane early and safely.
