What does a left arm and hand bent upward indicate?

A left arm and hand bent upward signifies a right turn. This hand signal is a universally recognized method of indicating the driver's intention to turn right. It is important for communication with other drivers and pedestrians, especially in situations where turn signals might not be functioning or when a driver prefers to use hand signals for better visibility.

In contrast, a straight arm indicates going straight, while a left arm bent downward is the signal for slowing down or stopping. Understanding these hand signals is crucial for safe driving, as they enhance awareness and promote better understanding among road users.
