What does it mean if a driver signals with their right arm extended?

When a driver extends their right arm out the window, it is a clear signal indicating that the driver is making a right turn. This hand signal is a conventional method for drivers to communicate their intention to others on the road, especially in situations where signaling with the vehicle's turn signal may not be visible or operational.

Using the right arm extended for this purpose adheres to standard traffic hand signals, which are intended to enhance road safety by ensuring that other drivers and pedestrians can anticipate the driver’s movements. Recognizing this signal helps others understand that the driver plans to change direction to the right, allowing for safer navigation around the vehicle.

Other options involve incorrect interpretations of the signal. For instance, if the arm is extended downward, it would indicate that the driver is stopping or slowing down, while an upward extension would signal a left turn. Understanding these signals is critical for safe driving practices and effective road communication among all users.
