What does a right arm extended with the palm down signify?

A right arm extended with the palm down is a standard hand signal for a right turn. This gesture indicates to other drivers and pedestrians that the individual intends to make a right turn, helping to ensure that traffic flows safely and effectively. Hand signals such as this are important for communication on the road, especially in situations where vehicles may not have the necessary indicators functioning or in areas where visibility is limited. Understanding these signals is essential for both drivers and pedestrians to promote safety and awareness on the road.
