What is the correct hand signal for a left turn?

The hand signal for a left turn is to extend your left arm straight out to the side. This signal is crucial for communicating your intentions to other drivers and pedestrians when operating a vehicle. It is important for ensuring safety on the road, as visual cues help prevent misunderstandings and potential accidents.

This method of signaling is consistent with traffic laws and conventions, making it a universally recognized way to indicate a left turn. Other options do not represent the appropriate signal for a left turn—extending an arm upward, for instance, is commonly used to signal a right turn or to indicate a stop, while extending a right arm represents a right turn. The act of signaling with the correct arm and position is an essential part of safe driving practices, reinforcing the importance of awareness and communication on the road.
