When making a left turn using hand signals, your left hand and arm should point which direction?

When making a left turn using hand signals, your left hand and arm should point straight out. This is the universally recognized signal for a left turn, as it clearly indicates to other road users your intention to turn left. By extending your arm horizontally, it creates a visible indication that can be easily seen by drivers and pedestrians, enhancing safety and communication on the road.

Other options may represent different signals; for instance, pointing upward typically signals a right turn, while a downward position usually indicates a stop or yield. A slightly bent arm is not a standard signal for any specific maneuver, making the straight-out position the most effective and recognized choice for signaling a left turn.
