The easiest thing to do is remove ourselves from the problem. Aim to change lanes on the motorway or dual carriageway, but only when it is safe to do so. Clearly indicate your intention to pull over. That way you can let the tailgater get past you, even if he or she is driving too fast for the conditions and/or breaking the speed limit.
Don’t be tempted to impose the speed limit on somebody who is clearly hell bent on breaking it. And if you choose not to let the tailgater past, there is a danger that he will try to “undertake” you, posing an additional risk for other road users.
We are often asked what can you do if you’re being tailgated in a 30mph zone on a single carriageway?
Pulling over here may not be practical either. But do not be intimidated into speeding up just because somebody is right on your back bumper. Instead, create an additional stopping distance between you and the vehicle in front so that you when you do brake, you can do so smoothly. Think of yourself as adding a little “buffer” zone for the tailgater, whether he appreciates it or not. When the time comes to brake, you can do so gently, giving a clear signal of your intention via your stop lights. The more time your stop lights are on, the more time the tailgater has to register that and pull back.
