Road Signs
A sign showing a curved arrow doubling back, with a red circle and slash over it, means:
Show Answer & Explanation
Correct Answer: B. You must not turn to go in the opposite direction
A 'No U-turn' sign prohibits turning around to reverse direction at that location. U-turns are dangerous at busy intersections where crossing traffic may not see you; the sign appears where the risk is highest.
Why the other answers are wrong
- A.U-turns are allowed only from the left laneThe red-circle-slash is absolute; no U-turn is permitted regardless of which lane you are in.
- C.U-turns are allowed after stopping completelyThe prohibition applies to the turn itself, not the stopping manoeuvre; stopping before a U-turn does not make it legal where banned.
- D.The road ahead has a sharp bendA sharp-bend warning uses a yellow diamond with a curved-road pictogram, not a red-circle-slash regulatory sign.
