What signs should be used to signal a left turn?

The correct method to signal a left turn is to extend the left hand straight out. This hand position is universally recognized as the proper signal for a left turn. By extending the left arm parallel to the ground, it provides a clear visual indication to other drivers and pedestrians of the intended action, ensuring safety and communication on the road.

Other signaling methods can convey different intentions. For instance, a bent left arm at a right angle upwards typically signals a right turn, while a bent left arm at a right angle downwards indicates a stop. The right hand extended palm down does not effectively communicate any turning intentions and is not a standard signal for turns. Understanding these distinctions helps ensure that drivers signal appropriately and maintain safe practices while driving.
