What should you do if you notice another vehicle approaching too closely while slowing down?

When you notice another vehicle approaching too closely while you are slowing down, the best action is to flash your brake lights to alert the driver behind you. This helps convey your intention to slow down or stop, giving the other driver a clear visual cue to be cautious and maintain a safe distance.

Effective communication with other road users is crucial for safety, especially in situations where your actions might not be immediately clear to other drivers. Flashing brake lights makes it obvious that you are slowing down and can help prevent rear-end collisions by prompting the tailing driver to react appropriately.

The other choices might not provide the same level of safety. Ignoring the situation can lead to an accident if the following vehicle does not realize you are slowing down. Speeding up is risky as it could lead to loss of control or more severe consequences if the other driver does not adjust their speed. Honking repeatedly could startle the other driver without necessarily helping them understand your intentions to slow down or stop safely.
