In the clip, the policeman is showing the way to the traffic jams but using the wrong hand signal, which is not in accordance with the regulations of the driving school. It is suggested that the policeman should be familiar with the law of pointing fingers, giving the right hand gesture with a style of being a traffic policeman. Hands raised vertically: People in traffic in all directions must stop.
Two arms or one arm outstretched: road users in front and behind the operator must stop; road users on the right and left side of the operator may go in all directions; The operator’s left arm is folded back and forth at the nape of the neck: the driver on the left of the driver goes faster. The driver’s right arm is folded back and forth in front of his chest: the driver on the right side of the road goes faster.
The operator’s left or right hand is at waist level and up and down: road users on the left or right of the operator slow down. The operator’s left or right hand is raised vertically perpendicular to the ground: the road user on the left or right of the operator stops. Right hand raised forward: road users behind and to the right of the operator stop; road users in front of the operator are allowed to turn right;
road users on the left side of the operator can go in all directions; pedestrians crossing the street behind the traffic controller are allowed to go. Left hand raised forward repeatedly, parallel to the right hand: road users on the left side of the operator are allowed to turn left in front of the operator. Above are some police orders that require the policeman to re-learn so that passers-by can follow the example.
