Which of the following signals would generally indicate "I want to turn left"?

The signal that indicates "I want to turn left" is represented by the left arm bent at the elbow towards the left. This hand gesture is universally understood and is a standard signaling method among drivers to communicate their intention to other road users. By using this signal, the driver ensures visibility and clarity about the intended action, which is crucial for safety on the road.

The other options do not accurately convey a left turn. Both arms extended generally indicate a stop, while a left arm raised is typically used to signal a right turn. A right arm raised, on the other hand, is often confused with a right turn signal, making it important to understand each gesture's specific meaning. Understanding these hand signals is essential for effective communication between drivers and maintaining safety on the road.
