Which statement correctly describes a blue circular sign with a left-turn arrow?

• A. It indicates a mandatory right turn.
• B. It indicates you may go straight.
• C. It indicates a mandatory left turn; you must proceed in that direction.
• D. It indicates you may turn left or go straight.

Answer: (C)

Blue circular signs indicate a mandatory instruction. A left-turn arrow on this sign means you must turn left and proceed in that direction; going straight or turning right isn’t allowed here. So the statement that describes a mandatory left turn is the correct one. The other options conflict with the left-turn requirement: a right-turn symbol would indicate turning right, going straight is not permitted when a left-turn arrow is shown, and a sign allowing both left or straight would show multiple arrows or wording indicating both options.
