What is the correct hand signal for a left turn?

The correct hand signal for a left turn is to extend the left arm straight out to the side. This signal helps communicate the intention to other drivers, cyclists, and pedestrians about the driver’s intention to turn left. The left arm extended horizontally is recognized universally as the standard hand signal for a left turn, making it a clear and visible indication.

In practice, hand signals are essential for safe driving, especially when vehicles are not equipped with functioning turn signals or when visibility is compromised. Using the left arm ensures consistency with established traffic laws and signals, aiding in effective communication on the road. This practice enhances road safety for everyone and reduces the likelihood of accidents caused by misunderstandings of a driver's intentions.
