Following distance — Wisconsin Permit Test

Following distance on the Wisconsin permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Wisconsin teaches the four second following distance rule for deciding how far back to drive.

Distance in feet changes with speed, so counting seconds works at any speed. Four is the number Wisconsin picks.

Use the “Four Second Following Distance Rule.”

Wisconsin Motorists' Handbook, p.10

To use the following distance rule, pick a stationary object ahead and count until the car reaches it.

A tree or a sign holds still while you move, so it can time you. Guessing the gap by eye is what people get wrong.

To do this pick out a stationary object as far ahead as you can clearly see.

Wisconsin Motorists' Handbook, p.10

A driver adds a second of following distance for every adverse condition, such as heavier traffic, rain, snow or ice.

Wet road, longer stop. The four seconds were measured on a dry one.

Add a second for every adverse condition such as heavier traffic, rain, snow and/or ice.

Wisconsin Motorists' Handbook, p.10

A driver who is being tailgated should slowly reduce speed, which encourages the other driver to go around.

Braking hard at a tailgater invites the crash you are trying to avoid. Easing off gives them room to pass.

If someone is tailgating you, slowly reduce your speed.

On the test

How many seconds of following distance does the Wisconsin rule call for?

4 seconds. Distance in feet changes with speed, so counting seconds works at any speed. Four is the number Wisconsin picks. Wisconsin Motorists' Handbook, p.10: “Use the “Four Second Following Distance Rule.””

How this works

Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.

You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.

Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
