What does it mean if a driver is signaling with their arm out the window and pointed downward?

When a driver has their arm extended out the window and pointed downward, it is a universal hand signal indicating that they are intending to stop. This gesture is used to communicate with other drivers and pedestrians, providing clear information about the driver's actions ahead of time. Recognizing this signal can enhance road safety, allowing others to anticipate the driver's next move and react accordingly.

The other options provided, such as signaling for a turn, seeking help, or changing lanes, involve different arm positions and movements that convey distinct messages. For example, signaling a right turn typically involves the arm being extended straight out or up, while a left turn would have the arm extended straight out, and signaling for help often includes different gestures altogether. Understanding these signals supports safe driving practices and effective communication on the road.
