What are the differences between lane change signals and slow down signals?

[OKendra]

The differences between lane change signals and slow down signals are as follows: 1. The slow down signal involves waving the hand horizontally downward, while the lane change signal involves waving the hand vertically to the left. 2. The lane change signal is one of the traffic police hand signals, indicating that vehicles should vacate the designated lane and slow down. The right arm is extended forward with the palm facing left, and the right arm swings horizontally to the left. 3. The new eight types of traffic police hand signals include: stop signal, go straight signal, left turn signal, left turn waiting signal, right turn signal, lane change and slow down signal, slow down signal, and signal for vehicles to pull over. 4. Among the original 11 hand signals, the rarely used and redundant two stop signals and two go straight signals were merged into one stop signal and one go straight signal, respectively. The 'large left turn signal' was canceled, while the frequently used and well-known hand signals familiar to traffic participants were retained.
