What is the correct hand signal for a left turn?

The correct hand signal for a left turn is to extend your left arm straight out. This signal clearly indicates your intention to turn left, and it's easily recognizable by other drivers and pedestrians. It’s important for maintaining safety on the road, as hand signals can provide critical information about your movements, especially in situations where turn signals may not be visible or functioning.

When you extend your arm straight out to the left, it aligns with common driving practices and is consistent with the signals used by most drivers who are communicating their intentions on the road. This signal helps ensure that others are aware of your movements, allowing them to adjust accordingly to prevent potential accidents.

Other options represent different maneuvers: raising your left arm above your head indicates a right turn, and extending your right arm straight out is a signal for a right turn as well. Lowering your arm parallel to the ground holds no specific meaning for a turn but is often used to signal a stop. Each hand signal has its own distinct purpose, making it essential for drivers to use the appropriate signal for their intended action.
