Lane change procedure — Louisiana Permit Test
Lane change procedure on the Louisiana permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Check your blind spots by turning your head and looking over your shoulder in the direction you plan to move.
Mirrors leave gaps beside the car, and a quick look over your shoulder is the only way to see them.
Check your “blind spots” by turning your head and looking over your shoulder in the direction you plan to move.
When changing lanes, identify a 4 to 5 second gap in traffic, signal and look again.
A gap that big gives you room to move over without making anyone brake for you.
Identify a 4 to 5 second gap in traffic, signal and look again in the direction of the lane change.
Blind spots are areas around your vehicle that you cannot see with your mirrors.
A whole car can hide in a blind spot, so knowing what one is tells you why mirrors are not enough.

On the test
How should you check your blind spot before changing lanes?
Look over your shoulder toward the lane. Mirrors leave gaps beside the car, and a quick look over your shoulder is the only way to see them. Class D & E Driver's Guide, p.63: “Check your “blind spots” by turning your head and looking over your shoulder in the direction you plan to move.”
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.
