Changing lanes and blind spots — Minnesota Permit Test
Changing lanes and blind spots on the Minnesota permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Before moving into another lane, make sure you have space to the side, behind and ahead of your vehicle.
A gap that is only beside you closes the moment the car behind it keeps coming.

Turn your head to check the lane you are moving into rather than relying only on your mirrors.
Mirrors have a hole in them exactly the size of a car. Turning your head is what fills it.
Turn your head to check the lane you are moving into for vehicles. Don’t rely solely on mirrors; you may miss vehicles in your blind spots.
Blind spots are areas around your vehicle where your view is blocked and mirrors show nothing.
It is not a small gap. A whole car can sit there while all three mirrors look empty.
Blind spots are areas around your vehicle where your view is blocked.
The design of your vehicle and the position of its roof pillars decide where your blind spots are.
Every car hides a different piece of the road, which is why the mirrors have to be learned car by car.
The design of your vehicle and the position of the roof pillars determine the location of your blind spots.
Dirty windshields and glaring lights can create temporary blind spots.
A film of grime turns oncoming headlights into a wall of light with a pedestrian hidden behind it.
Dirty windshields and glaring lights can also create temporary blind spots.

On the test
What space must you have before changing lanes?
Space to the side, behind and ahead. A gap that is only beside you closes the moment the car behind it keeps coming. Minnesota Driver’s Manual, p.28: “make sure you have space to the side behind and ahead of your vehicle before moving into another lane”
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.
