J turns — Minnesota Permit Test

J turns on the Minnesota permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.

The rules

At a J-turn, drivers on the side street approaching a divided highway always turn right.

The design removes the crossing movement entirely, because that is the one that kills people.

At a J-turn, drivers on the side street approaching the divided highway always make a right turn.

Minnesota Driver’s Manual, p.32

To cross the highway at a J-turn you come to a complete stop, turn right, then use the left-turn lane at the median opening to make a U-turn.

You end up going the way you wanted, having never driven across a lane of traffic.

Enter the designated left-turn lane that leads to the median opening and complete a U-turn.

Minnesota Driver’s Manual, p.32

J-turns are used to cut deaths and injuries from broadside crashes on four-lane divided highways.

A broadside hit puts a car door between two vehicles, and there is nothing in a door.

J-turns are used to decrease fatalities and injuries caused by broadside crashes on four-lane divided highways.

Minnesota Driver’s Manual, p.32

Completing the U-turn at a J-turn, you must yield to oncoming traffic and stop if necessary before entering the through lanes.

The U-turn is the one place the movement still crosses traffic, so that is where the yield sits.

When completing the U-turn, you must yield to oncoming traffic and stop if necessary, before entering the through lanes of the divided highway.

On the test

Which way does a driver on the side street turn at a J-turn?

Right. The design removes the crossing movement entirely, because that is the one that kills people. Minnesota Driver’s Manual, p.32: “At a J-turn, drivers on the side street approaching the divided highway always make a right turn.”

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.
