Slow Down Signal?

[DelAlexa]

The signal for vehicles to slow down is when the traffic police extend their right arm to the left front, palm facing downward, and the right arm and palm move vertically downward. Additional information: If the traffic police raise their right hand and lower their left hand, it is a stop signal; if the traffic police lower their right hand and extend their left hand to the side while moving it downward, it indicates to slow down. If the traffic police raise one hand forward and move the other hand downward, with the left hand moving downward, it signals a right turn; if the right hand moves downward, it signals a left turn. If the traffic police lower their left hand, slightly raise their right hand, and move it downward, it indicates for the vehicle to prepare for a left turn; similarly, if the traffic police lower their right hand, extend their left hand forward, and move it to the left, it means to change lanes.
