A simple request to calm down probably won't get to a tailgater's mind. It's as if some internal discomfort governs tailgaters' actions, making them drive dangerously. Any obstacle in their way may release their anger which is only one component of their explosive behavioral pattern.

There are three simple psychological tests that can help you understand them – and help prevent you from being one, too.

Test 1. If you see anyone driving too slow for present conditions, obstructing the left (fast) lane at a slow speed, or simply blocking your way, try to find a reasonable explanation for their behavior. Once you understand why they are behaving the way they are, you'll feel less angry and frustrated. You'll feel even better if you refrain from making any gestures or verbally abusing them.

Test 2. Think of the safety of your maneuver. Even today's cars in combination with modern road make tailgating extremely dangerous, especially for the tailgaters themselves. Sudden braking by the car ahead often lead to a collision. The higher the speed, the more severe the damage. And if the tailgater is driving a high-suspension pickup and has to swerve, it may tip over. Another danger is how many drivers now carry firearms. How safe would you be if the driver you are tailgating made you stop at a shoulder, and had a handgun?

Test 3. Are you sure everybody likes your driving style? Fellow citizens who criticize your behavior might even file a report of it. You can be convicted in court of reckless driving if the report was filed by a police officer. The result may be devastating for you: high fines and skyrocketing insurance premiums are the least of your worries. You may even be jailed for up to six months.

If you don't believe you need to share the road with other drivers, you should consider therapy or giving up your license.
