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 hand signal is universally recognized and effectively communicates your intention to other drivers and pedestrians that you plan to make a left turn. Extending your arm straight out to the left creates a clear visual signal that is easily seen by those around you, promoting safety on the road.

While other signals mentioned in the choices are used for different maneuvers, extending the left arm is specifically designated for left turns and is important for maintaining clarity in communication while driving. For instance, raising your left arm and bending it at a 90-degree angle indicates a right turn, while extending the right arm straight out communicates a right turn as well. Lowering your right arm signifies a stop. Understanding these signals is crucial for safe and effective driving, helping to prevent confusion about your intended actions on the roadway.
