What is the correct hand signal for slowing down or stopping?

The correct hand signal for slowing down or stopping is represented by the arm bent down at the elbow. This gesture indicates to other drivers that you are reducing speed or preparing to stop. The positioning of the arm clearly communicates your intention to others on the road, making it an essential signal for ensuring safety during driving.

In contrast, extending the arm straight out to the left typically signals a left turn, while an arm bent up at the elbow indicates a right turn. Waving the arm side to side is not a standard signal and may confuse other drivers regarding your intentions. Using clear and recognizable hand signals is vital for sharing the road safely and effectively with other motorists.
