Truck common mistakes — North Dakota Permit Test
Truck common mistakes on the North Dakota permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Do not cut in front of a truck to reach your exit; slow down and exit behind it, which takes only a few extra seconds.
Cutting into the space in front of a truck takes away the room it needs to stop, and it cannot stop as fast as you.
Cutting into the open space in front of a truck removes the truck driver’s cushion of safety.
Always pass a tractor-trailer completely, and always on the left side.
The trucker sees best on the left, and a car on the right side is in the largest blind spot.
Always pass a tractor-trailer completely and always on the left side.
Don't linger alongside a truck when passing; it leaves the trucker no way to take evasive action if an obstacle appears ahead.
If something blocks the road, the trucker needs your lane to swerve into, and you are sitting in it.
If you linger when passing any vehicle, your position makes it impossible for the trucker to take evasive action if an obstacle appears on the road ahead.
Tailgating a truck is dangerous because you take away your own cushion of safety if the vehicle in front of you stops short.
Close behind a truck you cannot see the road ahead, so you have no warning and no time when it brakes hard.
Tailgating a truck or car is dangerous because you take away your own cushion of safety if the vehicle in front of you stops short
Because of its large size, a tractor-trailer often appears to be traveling at a slower speed than it is.
A driver who thinks the truck is slow pulls out in front of it and is hit at the intersection.
Because of its large size, a tractor-trailer often appears to be traveling at a slower speed than it is.
A substantial number of car-truck collisions take place at intersections, because the car driver does not realize how close the truck is or how fast it is coming.

A substantial number of car-truck collisions take place at intersections because the driver of the car does not realize how close the truck is or how quickly it is approaching.
On the test
Your exit is coming up and a truck is beside you. What does the manual tell you to do?
Slow down and exit behind the truck. Cutting into the space in front of a truck takes away the room it needs to stop, and it cannot stop as fast as you. North Dakota Noncommercial Driver License Manual, p.32: “Cutting into the open space in front of a truck removes the truck driver’s cushion of safety.”
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.
