The no zone — New Hampshire Permit Test
The no zone on the New Hampshire permit test — 8 rules, each with the reason behind it and a question on it while it is fresh.
The rules
The No-Zone is the area around large trucks or buses where vehicles disappear from the commercial driver’s view into blind spots, on the sides, rear and front.
Naming the areas is how a driver learns to pass through them rather than sit in them.
These blind spots are on the sides, rear and front of the large vehicle.
Trucks have a large blind spot on their right side starting behind the cab and extending up to the length of the truck.
The right side is the worse of the two, and it is the side a car naturally ends up on when a truck moves over.

If the truck driver’s face cannot be seen in the side view mirror, then the truck driver cannot see the other vehicle.
It is a test a driver can run from their own seat in a second, and it answers the only question that matters.

Under ideal conditions a loaded truck with good tires and properly adjusted brakes traveling at 55 mph requires a minimum of 335 feet before coming to a complete stop.
That is more than a football field, in ideal conditions, which is why cutting in front of a truck is so dangerous.

A loaded truck needs greater than 1½ times the stopping distance of a car.
Half as far again is the margin a driver has to leave when pulling in front of one.
or greater than 1½ times the stopping distance of a car.
Large vehicles have huge blind spots directly behind them that extend up to 200 feet.
Two hundred feet is a long way back to still be invisible, which is why following a truck closely gains a driver nothing.

When passing a large vehicle a driver should look for the whole front of the vehicle in the rear-view mirror before pulling in front and maintaining speed.
Seeing the whole front of the truck is the only way to know you are past the part it cannot see.
When passing a large vehicle look for the whole front of the vehicle in the rear-view mirror before pulling in front and maintaining speed.
A driver should avoid driving in the right lane when traveling up or down hills, and near truck weigh stations where large vehicles re-enter faster traffic.
Trucks use the right lane on hills and at weigh stations, and staying out of it removes the conflict entirely.
Avoid driving in the right lane, if possible, when traveling up or down hills, as well as near truck weigh stations
On the test
Where are the No-Zones around a large vehicle?
On the sides, rear and front. Naming the areas is how a driver learns to pass through them rather than sit in them. New Hampshire Driver's Manual, p.38: “These blind spots are on the sides, rear and front of the large vehicle.”
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.
