During a sudden stop, what should you do to signal your intentions?

Flashing your brake light is the appropriate action during a sudden stop to signal your intentions to other drivers. This alert informs those behind you that you are slowing down and helps to prevent collisions, as it provides clear visibility of your actions. A flashing brake light is a universally recognized signal indicating that a vehicle is stopping or slowing down, which is critical on the road, especially in sudden situations.

Using turn signals, waving your hands, or turning your head to the right are less effective in this scenario, as they do not clearly communicate the immediate need for other drivers to slow down. While turn signals are essential for indicating changes in direction, they do not specifically convey a sudden stop. Waving hands may not be visible to all drivers, and turning your head does not provide a clear message to those behind you. Therefore, flashing your brake light is the most effective way to communicate your intentions during an abrupt stop.
