What is the hand signal for a left turn?

Answer: A — Left arm extended straight out

The hand signal for a left turn is indicated by extending the left arm straight out from the driver's side of the vehicle. This signal is universally recognized and conveys the driver's intention to turn left to other road users, including pedestrians, cyclists, and drivers in surrounding vehicles. Properly signaling intentions while driving is crucial for maintaining safety on the road and ensuring that other road users are aware of your actions. Using this specific hand signal helps to prevent confusion and promotes safe maneuvering during turns. The other choices represent different signals: a left arm bent upward indicates a right turn, while a left arm bent downward signals a stop. Both arms extended outward is a signal for a lane change or to indicate that a vehicle is slowing down, not a turn. Understanding these hand signals is essential for all drivers in Illinois and contributes to safe driving practices.
