What hand signal indicates slowing down or stopping?

The signal indicating slowing down or stopping is represented by the left hand and arm pointing downward. This gesture clearly communicates to other drivers and pedestrians that your vehicle is reducing speed or coming to a stop.

In driver communication, hand signals are important for indicating intentions, especially in situations where vehicle signals might not be visible or are malfunctioning. Using the downward position for your arm effectively conveys the action of deceleration.

The other options represent different signals: the left hand and arm pointing straight out indicates a left turn, the right hand and arm pointing straight out indicates a right turn, and the right hand pointing downward does not correspond to a standard hand signal for slowing down or stopping. Understanding these signals is essential for safe and effective communication on the road.
