How can you warn drivers behind you that you will be slowing down?

Tapping your brake pedal a few times is an effective way to warn drivers behind you that you are about to slow down before making a complete stop. This action causes your brake lights to flash on and off, alerting the drivers behind you that you are decelerating. It's a visual cue that is easily recognizable in most driving situations, allowing the following vehicles to react in time and maintain a safe distance.

Using your hazard lights typically indicates that your vehicle is stationary or experiencing a problem, which may not clearly convey the intention to slow down. Sounding your horn isn't an effective method for signaling deceleration; it's often used for alerting other drivers of immediate hazards. Making a sudden stop could create a dangerous situation, as it does not give adequate warning to the vehicles behind, potentially leading to collisions. Thus, tapping the brake pedal serves as the most appropriate and safest warning method for approaching vehicles.
