What hand signal is used for a left turn?

The hand signal used for a left turn is represented by extending the left arm straight out to the side. This signal is a universally recognized indication that the driver intends to turn left. By using this hand signal, drivers effectively communicate their intentions to other road users, including vehicles, cyclists, and pedestrians, helping to enhance safety on the road.

In addition to being a widely accepted signal, extending the arm allows for maximum visibility, making it clear to others what the driver plans to do. It's important for drivers to use hand signals, especially if their vehicle's turn signals are not functional or if they are riding a bicycle where signals are necessary for safety.

Other hand signals are designated for different actions, such as signaling a right turn or stopping, but the left turn is specifically indicated by the left arm being extended straight out. Understanding and using these signals appropriately is crucial for safe driving practices.
