What is the proper hand signal for a left turn?

The proper hand signal for a left turn is to extend your left arm out straight. This hand position is recognized universally as a clear indication that the driver intends to make a left turn. The extended arm communicates the driver's intention without the need for electronic signals or turn indicators, which is particularly important in situations where visibility might be low or when signaling devices fail.

Using this hand signal is essential for ensuring that other drivers and pedestrians are aware of your intentions on the road, thereby enhancing safety while maneuvering. In contrast, bending the left arm upwards typically signifies a right turn, and extending the right arm out straight indicates a left turn, which can create confusion if misused. Keeping both hands on the wheel fails to communicate any intention, which does not follow proper signaling protocols for safe driving practices.
