Slow and heavy vehicles — West Virginia Permit Test
Slow and heavy vehicles on the West Virginia permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Slow moving vehicles must display a special triangular emblem to warn approaching drivers.
A triangle is used for nothing else on the back of a vehicle, so it reads at a distance.
A fully loaded tractor-trailer traveling 55 miles an hour needs three times the distance a car needs to stop.
Cutting in and slowing down asks for a stop in a distance the truck does not have.
A truck's blind spots are called the No-Zone, and the easiest way to tell whether you are in one is to look for the driver's reflection in the side mirror: if you cannot see it, they cannot see you.
The mirror works both ways, so the test is the same in both directions.
Heavy trucks typically weigh 80,000 pounds, are longer and heavier than a car, and need much more room to turn.
Weight is what decides how long a stop takes, and a loaded truck carries twenty times a car's.
After passing a truck in dry conditions, give two seconds before merging back to the right; in wet conditions give at least four to six seconds of space.
Pulling in early puts your back bumper where the driver cannot see it at all.
Never slam on your brakes in front of a truck, never cut a truck off to reach your exit, never tailgate one, and never pass one on the right during a turn.
A truck cannot stop or swerve the way a car can, so every one of those leaves it no way out.
On the test

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.
