Mirror adjustment — Louisiana Permit Test
Mirror adjustment on the Louisiana permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
To set the driver's side mirror, place your head against the driver's side window and adjust it so you can barely see the side of your car.
Pointing the mirror out this far covers the space beside you that the inside mirror cannot show.
Place your head against the driver’s side window and adjust the driver’s side mirror so you can barely see the driver’s side of your car.
To set the passenger's side mirror, move your head as close to the center of the car as possible and adjust it so you can barely see the passenger's side of your car.
Setting it from the middle aims the mirror at the lane beside you, not at your own door.
Move your head as close to the center of the car as possible and adjust the passenger’s side mirror so you can barely see the passenger’s side of your car.
The center inside rearview mirror is the primary mirror.
The inside mirror shows the most of the road behind you, so it is the one you check first.
Always remember that the center inside rearview mirror is the primary mirror.
To test your mirrors, watch a car pass you: it should show in your side mirror before it fully leaves the center rearview mirror.
If a car disappears from one mirror before it shows in the next, you have a blind spot it can hide in.
The passing car should be seen in your side mirror before it fully leaves the center rearview mirror.
On the test
How should you set your driver's side mirror?
Head on the window, barely seeing your car's side. Pointing the mirror out this far covers the space beside you that the inside mirror cannot show. Class D & E Driver's Guide, p.64: “Place your head against the driver’s side window and adjust the driver’s side mirror so you can barely see the driver’s side of your car.”
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.
