How should you signal for a left turn?

To signal for a left turn, extending your left hand straight out is the appropriate and standard method. This hand signal indicates to other drivers and pedestrians that you intend to make a left turn. It's a clear and recognizable gesture that helps ensure safety on the road by providing a visual cue to those around you.

Using your left hand straight out is part of the conventional signaling practice outlined in driver education guidelines and ensures that other road users can easily understand your intentions. Proper signaling is essential for maintaining safe driving practices and facilitating smooth traffic flow.

Other methods like waving your left hand up and down or using your hazard lights do not communicate the specific intent of turning left and could create confusion on the road. Signaling with your right hand would indicate a right turn, which does not apply in this situation. Thus, the proper technique is to extend your left hand straight out to clearly and effectively signal a left turn.
