Passing large vehicles — New York Permit Test
Passing large vehicles on the New York permit test — 7 rules, each with the reason behind it and a question on it while it is fresh.
The rules
When a driver passes a large vehicle it takes a longer time and requires more space than when they pass a car, and on a two-way road they should leave more time and space.
A trailer is many car lengths long. Getting around it takes far more road.
When you pass When you pass a large vehicle, it takes a longer time and requires more space than when you pass a car.
A driver should make sure they can see the whole front of a large vehicle before they return to their lane after passing it.

Make sure you can see the whole front of the vehicle before you return to your lane after you pass.
A large vehicle normally loses speed on a grade or a hill, and as a driver's own vehicle begins a downward grade the speed of the other vehicle can increase significantly, which increases the time it takes to pass it.
A truck crawls uphill and runs away downhill. The hill decides how long the pass takes.

How does passing a large vehicle compare with passing a 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.
