Free New Hampshire CDL practice questions

Five questions from the general knowledge, air brakes and combination vehicles banks, the three tests most New Hampshire Class A applicants take first. Show the answer to read the explanation.

Cargo loaded so that the center of gravity is high:
- Improves traction on the drive wheels
- Makes the vehicle more likely to tip over on curves or in sudden steering moves
- Makes the vehicle easier to stop
- Has no effect on handling
Show answer
Answer: B. Makes the vehicle more likely to tip over on curves or in sudden steering moves
Keep the heaviest parts of the load low and spread them evenly between axles. Piling heavy cargo on top raises the center of gravity and the rollover risk.

Overloading a vehicle can:
- Improve fuel economy
- Make the brakes work better because of extra weight
- Make it harder to control, lengthen stopping distance, and cause brakes to overheat on downgrades
- Reduce tire wear
Show answer
Answer: C. Make it harder to control, lengthen stopping distance, and cause brakes to overheat on downgrades
Extra weight slows you on upgrades, makes you go faster on downgrades, and stretches stopping distance. Overloads also stress tires and suspension and are illegal.

Even if you did not load the cargo, as the driver you are responsible for:
- Only driving the vehicle; the shipper is responsible for everything else
- Nothing, as long as the paperwork is signed
- Only the weight on the steering axle
- Recognizing overloads and poorly balanced weight, and making sure the cargo is secured
Show answer
Answer: D. Recognizing overloads and poorly balanced weight, and making sure the cargo is secured
The driver answers for the load on the road. Inspect it before you leave, know your weights, and refuse a load that is unsafe or over the legal limit.

When hauling livestock in a trailer that is only partly full, you should:
- Use false bulkheads to keep the animals bunched together
- Drive faster so the animals do not move around
- Leave extra room so the animals can lie down
- Open the vents wide to calm the animals
Show answer
Answer: A. Use false bulkheads to keep the animals bunched together
Loose animals move around and shift the vehicle's weight, which can roll the trailer in a turn. Bulkheads keep them bunched. Even so, drive carefully because animals will still lean on curves.

Oversized loads:
- May be hauled anywhere at any time as long as the truck is strong enough
- Require special permits and are usually allowed only at certain times, sometimes with escort vehicles and special signs
- Need no permit if the trip is under 50 miles
- Are allowed only on interstate highways
Show answer
Answer: B. Require special permits and are usually allowed only at certain times, sometimes with escort vehicles and special signs
Over-length, over-width, or overweight loads need transit permits. They are often limited to daylight hours or certain days and may require pilot vehicles, flags, and 'Oversize Load' signs.

Every CDL test for New Hampshire drivers

Each page has ten free sample questions, the real question count, the 80% pass mark and what the test covers.

How the New Hampshire CDL knowledge test works

You take the general knowledge test first; it is required for every CDL class. Class A drivers add the combination vehicles test. Almost everyone takes the air brakes test, because skipping it puts an air brake restriction on the licence. Endorsements (hazmat, tanker, doubles/triples, passenger, school bus) each have their own knowledge test. Pass the tests and you hold a commercial learner's permit; the skills test in a truck comes later.

Fees, appointment rules and test centre locations are set by New Hampshire and change over time, so check the state driver licensing agency before you go. What does not change is the content, and that is what PassRig drills.
