Large vehicles — Maine Permit Test
Large vehicles on the Maine permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Never try to pass behind a truck or bus that is backing up.
The driver of a backing truck cannot see a small car crossing behind it.
Never attempt to pass behind a truck or bus that is backing.
If you cannot see the mirrors of the large vehicle ahead of you, its driver probably cannot see you, so stay out of its blind spots.
A truck driver who cannot see you may brake or change lanes right into your car.
If you cannot see the mirrors of the large vehicle ahead of you, the driver probably can't see you so stay out of the blind spots.
A large vehicle's speed may drop sharply going uphill and rise quickly going downhill.
A car following close behind a truck on a climb can suddenly find itself on its bumper.
The speed of a large vehicle might drop sharply when the vehicle is going uphill; this same vehicle might often gain speed quickly when starting downhill.
Never pass or pull in front of a large vehicle that is already slowing or stopping, because its driver planned the stop around the space ahead.
A car cutting into that space leaves a heavy truck with too little room to stop.
Never pass or pull in front of a large vehicle that is already slowing or stopping.
Large vehicles often have to swing to the left before turning right, so do not drive into their turning path.
A car slipping into the gap on the right gets squeezed against the curb by the trailer.

On the test
A truck is backing up in front of you. What should you not do?
Pass behind it. The driver of a backing truck cannot see a small car crossing behind it. Maine Driver’s License Manual, p.106: “Never attempt to pass behind a truck or bus that is backing.”
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.
