If a tailgater is behind you, what should you do?

When a tailgater is behind you, the best course of action is to move to another lane or pull to the side if it's safe to do so. This response helps to alleviate the pressure of the tailgater and reduces the risk of a rear-end collision. By changing lanes or pulling over, you create a safe distance between your vehicle and the tailgater, allowing you to continue driving without undue stress and minimizing danger to both yourself and other road users.

Maintaining a safe space between vehicles is a key principle of defensive driving; this principle allows drivers to react effectively to unexpected situations. Therefore, making a maneuver to create that space is the most sensible and safe option in this scenario.
