Which action is appropriate if another vehicle is tailgating you?

When another vehicle is tailgating you, merging into another lane when it's safe to do so is the most appropriate action. This maneuver allows you to create distance between yourself and the tailgating vehicle, reducing the likelihood of a collision. By safely changing lanes, you enable the tailgater to pass you, which can alleviate the pressure and stress that both drivers might be feeling.

Creating distance is essential for safety; it gives both you and the tailgating vehicle more space to react to any sudden changes in traffic or road conditions. Moreover, maintaining a calm and controlled response, such as changing lanes safely, is much better than aggressive actions that could escalate the situation. The other options, like speeding up or braking suddenly, can lead to dangerous situations on the road. Ignoring the tailgater while maintaining speed does not address the safety concern and could potentially lead to an accident if the tailgater does not adjust their driving behavior.
