When should you use your left hand to signal a turn?

Answer: B — Hand held outward

Using your left hand to signal a turn is important for clear communication with other drivers and pedestrians. When you hold your hand outward, it indicates to others that you are preparing to make a left turn. This method of signaling helps ensure that everyone on the road is aware of your intentions, contributing to safer driving. The option involving a hand held upward is typically used to signify a right turn, while holding the hand downward is a signal for stopping or slowing down. The action of a hand wave is ambiguous and does not effectively convey a specific turn signal. Therefore, using your hand held outward is the accepted method for indicating a left turn to others on the road.
