What is the hand signal to indicate a stop?

The hand signal to indicate a stop while driving is represented by the left arm bent downward. This signal is crucial for communicating to other road users your intention to stop, especially when you are unable to use your vehicle's brake lights. By extending your left arm downwards at a 90-degree angle, it offers a clear visual indication that you are slowing down or preparing to stop.

Other signals such as a left arm straight out or bent upward serve different purposes, such as indicating a left turn or a right turn, respectively. Therefore, it is essential for drivers to familiarize themselves with these hand signals to ensure safe and effective communication on the road. Knowing the correct signal for stopping helps maintain safety for both the driver and others sharing the roadway.
