What is the correct hand signal for a left turn?

The correct hand signal for a left turn is to extend your arm straight out from the driver's side window. This universally recognized gesture indicates to other drivers and pedestrians that you intend to turn left, allowing them to anticipate your movements on the road. It is an important communication tool, especially in situations where turn signals might not be visible or functional.

Using an extended straight arm is crucial for safely and effectively conveying your intentions while driving. Although the other options correspond to different hand signals, they do not represent a left turn. A bent arm upward signals a right turn, and a bent arm downward indicates a stop or slow down. The statement about hand signals not being required is incorrect, as signaling turns is not only a best practice but often a legal requirement, depending on local traffic laws. Therefore, understanding and using the correct hand signal enhances road safety for everyone involved.
