What does it mean if a driver is using hand signals?

When a driver uses hand signals, it typically indicates their intent to turn or stop. This method is crucial, especially in situations where the vehicle's turn signals may be malfunctioning or for cyclists and motorcyclists who may not have indicators. Hand signals, such as extending an arm straight out to indicate a left turn, bending the elbow upward for a right turn, or moving the arm downwards to signal a stop, provide clear and direct communication to other road users about the driver’s intentions. Thus, hand signals play a vital role in promoting safety on the road by ensuring that surrounding drivers and pedestrians are aware of the driver's planned maneuvers.
