Ask A Trooper

Sgt. Jesse Grabow

Question: I can’t help but notice but it seems like a lot of people are following each other too close out on the highways. It’s been many years since I was in driver’s education but what is the recommendation for following distance?

  Answer: Here is information that is shared in the Minnesota Driver’s Manual. Applying the “Three-Second Rule” helps you keep a safe distance between your car and the vehicle ahead of you. This rule is for standard-length vehicles driving in ideal conditions.

  1. Choose a fixed reference point at the side of the road ahead, such as a telephone pole, signpost, tree, or bridge.

2. When the vehicle ahead of you passes the reference point, begin counting: “One-thousand-one, one-thousand-two, one-thousand-three.”

3. If you pass the reference point before you finish counting, you are following too closely.

4. Gradually slow down until you reach a safe following distance and speed.

  When road conditions are poor, or if you are driving a vehicle longer than the standard length, increase your following distance to a four- or five second count. If the vehicle behind you is following too closely, slow down slightly and allow it to pass.
