Nearly 40% of all auto accidents nationally are rear-end collisions. To help prevent a rear-end collision, you can apply a great defensive driving tactic called the three-second rule. Choose a landmark on the side of the road, and count the amount of time it takes between the back end of the car in front of you to pass the marker and for you to pass the same marker. If your count is less than three seconds, you are driving too close to the vehicle in front of you to give yourself enough time to stop in case the car in front of you brakes abruptly.
Driving too close to the car in front of you is very dangerous, and is commonly known as tailgating. Be sure to give yourself plenty of time on the road to get to your destination, and be mindful of the three-second rule at all times.
