What is the correct hand and arm signal for a left turn?

The correct hand and arm signal for a left turn involves extending your arm straight out the window. This signal clearly communicates to other road users that you intend to make a left turn. When your arm is straight out, it effectively indicates to drivers and pedestrians around you the direction you plan to go, promoting safety and reducing the risk of miscommunication on the road.

The other options do not accurately represent the standard signal for a left turn. An arm out and down typically indicates stopping or slowing down, while an arm out and up signifies a right turn. An arm bent toward the front of the car, also known as the "hooked" signal, is not a recognized signal for turns and could cause confusion among other drivers. Proper hand signals are crucial for safe driving and help maintain clear communication on the road.
