Changing lanes checks — Maine Permit Test
Changing lanes checks on the Maine permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Blind spots are areas around your vehicle that your mirrors do not cover, caused by headrests and door pillars that block your vision.
A car sitting behind your door pillar can vanish from view right as you move over.
Blind spots are areas around your vehicle caused by headrests and door pillars that block your vision.
Whenever you change lanes, signal and look over your shoulder in the direction you are moving; do not rely only on your mirrors.
A car beside your rear corner can be in no mirror at all.
Never rely solely on your rearview mirrors when making a lane change.
To change lanes, find a gap in traffic, signal, and then look again before changing lanes.
The gap you found before signaling may be gone by the time you move.

On the test
According to the manual, what helps cause blind spots?
Headrests and door pillars. A car sitting behind your door pillar can vanish from view right as you move over. Maine Driver’s License Manual, p.63: “Blind spots are areas around your vehicle caused by headrests and door pillars that block your vision.”
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.
