What is the proper hand signal for a left turn?

The proper hand signal for a left turn is indicated by extending the left arm straight out. This signal is universally recognized and serves as a clear communication to other drivers and pedestrians that the driver intends to turn left. When the left arm is fully extended, it creates a visual cue that is easily observable from cars behind and beside the vehicle, enhancing safety on the road.

In contrast, bending the left arm upward signifies a right turn, while extending the right arm straight out also indicates a right turn. Bending the right arm downward signals a stop. Each hand signal has a specific meaning and is essential for effective communication while driving, especially in situations where turn signals may not be visible to others. Understanding and using these signals ensures drivers can safely navigate and indicate their intentions to others on the road.
