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 from the vehicle. This signal is universally recognized and helps communicate your intent to turn left to other drivers and pedestrians. By extending the left arm, you create a clear and visible indication of your direction, making it easier for others on the road to understand your intentions.

When signaling a left turn, using your left arm in this manner ensures clarity. It's important for drivers to use hand signals to improve safety, particularly in situations where turn signals may not be seen due to vehicle positioning or other visual obstructions.

The other options represent different signals or are incorrect for indicating a left turn, which can cause confusion on the road. Understanding the proper hand signals is a critical aspect of safe driving practices and is essential for maintaining clear communication with others while operating a vehicle.
