What is the first step to take if you see brake lights ahead of you?

When you see brake lights ahead, the first step you should take is to begin to slow down. Brake lights indicate that the vehicles in front of you are stopping or slowing down, which means it's important to react quickly to avoid a collision. By slowing down, you maintain a safe following distance and give yourself enough time to react to any further changes in traffic.

This approach also helps to ensure the safety of both your vehicle and those around you, as sudden stops can lead to rear-end collisions if drivers do not respond appropriately to the braking signals of the vehicles ahead.
