What Is the 4 Second Rule?

A 4-second following distance, as shown above in Area 1 of the space-management diagram, will allow you to steer or brake to avoid a hazard safely on the highway, if the pavement is dry. If you are following too closely and the vehicle ahead of you stops or slows suddenly, you will not be able to avoid a crash.

What are the steps in the 4 second rule?

You should apply the four-second rule when it's wet, frosty or when you are towing a trailer. The four-second rule means that you leave four seconds between you and the vehicle in front. It gives you more time to react and more time to stop.

What does the 4 second rule mean in driving?

Count slowly and steadily. If you did NOT reach 4 before the point passed your front bumper, then you are too close to the car ahead. At 55 mph, you should be almost 323 feet behind the car ahead.
