Truck no zone — North Dakota Permit Test
Truck no zone on the North Dakota permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A truck's blind spots, the no-zones, reach up to 20 feet in front of the cab.
A car tucked right in front of the cab is below the trucker's view, and the truck can roll into it.
While truckers do enjoy a better forward view and have bigger mirrors, they still have serious blind spots or no-zones into which a car can disappear from view—up to 20 feet in front of the cab, on either side of the tractor-trailer, particularly alongside the cab, and up to 200 feet in the rear.
A truck's no-zone behind it reaches up to 200 feet in the rear.
A car following far back can still be out of the trucker's sight, so the trucker may stop or back up without knowing it is there.

If you can't see the truck driver in his or her side mirror, the truck driver can't see you.
A trucker who cannot see you may change lanes into you, so the mirror check tells you when you are hidden.
An excellent rule of thumb for drivers sharing the road with a tractor-trailer is, “If you can’t see the truck driver in his or her side mirror, he or she can’t see you.”
On the test
How far in front of a tractor-trailer's cab can its no-zone reach?
Up to 20 feet. A car tucked right in front of the cab is below the trucker's view, and the truck can roll into it. North Dakota Noncommercial Driver License Manual, p.31: “While truckers do enjoy a better forward view and have bigger mirrors, they still have serious blind spots or no-zones into which a car can disappear from view—up to 20 feet in front of the cab, on either side of the tractor-trailer, particularly alongside the cab, and up to 200 feet in the rear.”
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.
