Final answer:
When being tailgated, you should increase your following distance to maintain safety. Avoid flashing your brake lights or speeding up, and signal the tailgater only when it is safe and legal for them to pass you.
Step-by-step explanation:
If you are being tailgated, the correct response would be to increase your following distance. This allows for more space between your vehicle and the one in front of you, providing a larger safety buffer should you need to stop suddenly. It also gives the tailgater more room and a clearer view ahead, possibly encouraging them to pass or maintain a safer distance. It is important not to flash your brake lights or speed up since these actions can lead to aggressive driving situations or accidents. Instead, remain calm, ensure your safety, and maneuver according to traffic laws and circumstances. If it's safe and legal to do so, you may signal the tailgater to pass you when conditions allow.
