What is the hand signal for a left turn?

The hand signal for a left turn is represented by the left hand and arm being extended straight out from the vehicle. This signal is intended to inform other drivers and pedestrians that the driver plans to make a left turn, ensuring clear communication on the road. Using this method is important for maintaining safety and awareness, as it allows others to anticipate your movements.

While the other signals serve different purposes—such as the right hand pointing straight out indicating a right turn or the left hand and arm pointing upward for a right turn—the left arm extended horizontally is the universally recognized signal specifically for a left turn. This distinction is crucial for effective signaling while driving, as it helps prevent confusion and potential accidents.
