What is the proper hand signal for a left turn?

The proper hand signal for a left turn is to extend your left arm straight out. This is a universally recognized hand signal for indicating a left turn to other drivers and pedestrians, ensuring clear communication about your intended maneuver on the road. When you extend your left arm, it conveys your intention to turn left, which helps maintain safety and predictability in traffic.

The other options represented different signals or movements that do not effectively communicate a left turn. For instance, a right arm straight out indicates a right turn, while waving an arm up and down does not provide any clear directional information. Similarly, a left arm bent upwards signals a right turn, which could confuse other road users. Proper use of hand signals is essential for safe driving and compliance with traffic laws.
