How do you indicate that you are turning left?

Using your left turn signal is the proper method to indicate that you are turning left. The turn signal, when activated, communicates your intention to other drivers and pedestrians, ensuring that they are aware of your upcoming maneuver. This electronic indicator is a standardized signal in modern vehicles, making it universally understood on the road.

While extending your left arm out the window is indeed a valid method of signaling a left turn, it is typically used in older driving contexts or by cyclists. Activating hazard lights indicates a different situation, such as when your vehicle is stopped or experiencing a problem, and does not serve to communicate a left turn. Hand gestures can vary widely and may not be recognized by all drivers, so they are less reliable than the turn signal. Therefore, using your left turn signal is the safest and most effective way to convey your intentions to other road users.
