Yellow lane lines — Wisconsin Permit Test

Yellow lane lines on the Wisconsin permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Solid yellow lines separate traffic going in opposite directions, and two solid yellow lines mean no lane of travel can pass.

Two solid lines is the strongest marking on the road. Neither side gets to cross it to overtake.

These lines separate traffic going in opposite directions. Two solid yellow lines means that no lane of travel can pass.

Wisconsin Motorists' Handbook, p.35

A driver may cross a solid yellow line to turn into a driveway when it is safe to do so.

A turn into a driveway crosses the line for a moment and ends off the road. That is not the same as overtaking along it.

You can cross the line if you turn into a driveway and it is safe to do so.

Wisconsin Motorists' Handbook, p.35

A driver may pass a vehicle going less than half the speed limit where it is safe, except where it is farm equipment.

The rule is for something barely moving, not for someone driving a little under. Farm machinery is carved out of it.

You can pass a vehicle going less than half the speed limit if it is safe, except if it is farm equipment.

Wisconsin Motorists' Handbook, p.35

A dashed yellow line means a driver may pass other vehicles when it is safe to do so.

The dashes are painted where the view ahead is long enough to get by. The judgment about the gap is still yours.

This means you may pass other vehicles when it is safe to do so.

Wisconsin Motorists' Handbook, p.35

Where a dashed and a solid yellow line run together, the driver on the dashed side may pass and the driver on the solid side may not.

The line is a rule for each direction at once. Which half you are on decides which rule you get.

This means you may pass if you are on the dashed side of the line. If you are on the solid side of the line, you may not pass.

On the test

What do two solid yellow lines mean in Wisconsin?

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.
