Following Distance

Print Article Email article to a friend »

Following too closely is a common mistake made by new drivers. Try using the three-second rule to help determine your following distance:

Three-Second Rule

  • Watch the vehicle in front of you pass an object. Then count the time it takes for you to reach that same object. "One thousand one, one thousand two, one thousand three…"
  • If you are closer than three seconds, back off slightly until you reach a three-second following distance.
  • Sometimes you may need to use four seconds instead of three. Use the four-second rule in the following situations:
    • When traveling at speeds over 30 miles per hour
    • When driving in heavy traffic or bad weather
    • When following a motorcycle, truck or bus

It's important to remember that the three-second rule and four-second rule are just guidelines. They may not always provide enough distance between you and the car ahead. It is up to the driver to use their best judgment to decide if more space is needed.
