What is the hand signal for a left turn?

The correct hand signal for a left turn is indicated by extending the left arm horizontally out of the vehicle. This signals to other drivers and pedestrians that the driver intends to make a left turn. The horizontal position of the arm is clear and easily recognized, making it an effective communication method for indicating turning intentions.

Understanding proper hand signals is vital for safe driving, as they serve as essential communication tools, especially in situations where vehicles may not be equipped with functioning turn signals or when visibility is limited. In contrast, the option involving the left arm extended vertically is used for indicating a right turn, while extending the right arm horizontally signifies a right turn as well. The choice of both arms extended horizontally is not a standard signal for any specific action while driving.
