What does the hand signal for stop or slow down indicate?

The hand signal for stopping or slowing down involves extending the left arm out and bending it at a right angle, with the palm facing downwards. This gesture clearly communicates to other drivers, pedestrians, and cyclists that the vehicle is either stopping or reducing speed, which is crucial for road safety. It helps to ensure that other road users are aware of the driver's intentions and can respond accordingly, thereby preventing accidents or confusion on the road. Understanding this signal is essential for both drivers and those learning to drive, as it reinforces the importance of clear communication while navigating traffic.
