What is the appropriate action to take when being tailgated?

When you are being tailgated, slowing down or changing lanes is the most appropriate response. This action serves to create a safer distance between you and the vehicle behind you, reducing the risk of a rear-end collision. By slowing down, you can allow the tailgater to pass if it's safe to do so. Alternatively, changing lanes can also help remove yourself from a potentially dangerous situation, especially if the tailgater is behaving aggressively or if you feel uncomfortable.

Maintaining your speed or attempting to speed up can escalate the situation, as the tailgater may become frustrated. Abruptly applying the brakes can be dangerous and may lead to an accident, as it does not give the tailgater a safe opportunity to react. Thus, changing lanes or slowing down is a proactive measure to ensure your safety on the road.
