These directional signals can be used when turning or changing lanes. Arm signals are used with all vehicles, including cars, motorcycles, bicycles and buses. Motorcyclists can use their left arm to indicate a left turn as opposed to turning their right arm anticlockwise.

The slowing down signal is used commonly when a driver sees something that other drivers may not see due to reduced visibility.

Different countries have different rules and regulations about hand and arm signals, such as whether the palm or forearm should be facing up or down.Learn more about DMV & Records
