To avoid tailgating, drivers should:

Leave at least 25 feet between their vehicle and the vehicle ahead.
Look into their rear view mirror.
Brake suddenly and merge into another lane.
Use the “three-second rule”.
Explanation

Tailgating is a dangerous driving behavior that can lead to rear-end collisions. To avoid tailgating, you should use the “three-second rule”: when the vehicle ahead of you passes a certain point, count “one-thousand-one, one-thousand-two, one-thousand-three”. If you pass the same point before you finish counting, you are following too closely.
