Which sign prohibits right turns?

• A. No Right Turn
• B. No Left Turn
• C. No Tow Caravans
• D. No Vehicles Carrying Explosives

Answer: (A)

A circular sign with a right-turn arrow crossed out tells you that turning right at that junction is not allowed. It’s a prohibitory sign, so you must not perform a right turn here; you can go straight or turn left instead, following any lane markings or signals. This restriction helps prevent conflicts with traffic coming from other directions or with pedestrians. The other signs ban different things: one would prohibit turning left, another relates to caravans being towed, and the last to explosives—none of which describe a right-turn restriction.
