Green lights — Wisconsin Permit Test

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

The rules

A steady green light lets a driver go through the intersection, yielding to emergency vehicles and others as the law requires.

Green means the way is yours if it is empty. An ambulance takes it back from you.

Steady Green – You can go through the intersection.
Wisconsin Motorists' Handbook, p.33

A driver stopped at a light that turns green must allow cross traffic to clear before going ahead.

Somebody is always finishing the crossing as your light changes. Pulling away on the change is how you meet them.

If you are stopped and then the light turns green, you must allow cross traffic to clear before you can go ahead.
Wisconsin Motorists' Handbook, p.33

On a steady green a driver may turn left only when it is safe, because oncoming traffic has the right-of-way.

Green does not create a gap in the oncoming traffic. The turn waits for one.

If you are turning left, a steady green light means you may turn, but only when it is safe to do so. Oncoming traffic has the right-of-way.
Wisconsin Motorists' Handbook, p.33

A steady green arrow lets a driver turn in the direction of the arrow, with no oncoming or crossing traffic, but pedestrians must still be watched for.

The arrow holds the cars back and nothing else. People on foot still step into the turn.

Steady Green Arrow – You can turn in the direction of the arrow. There should be no oncoming or crossing traffic while the arrow is green. Remember to watch for pedestrians.
Wisconsin Motorists' Handbook, p.33

On the test

What does a steady green light allow a Wisconsin driver to do?

Go through the intersection. Green means the way is yours if it is empty. An ambulance takes it back from you. Wisconsin Motorists' Handbook, p.33: “Steady Green – You can go through the intersection.”

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.
