Sample questions

Six questions from the North Carolina bank, with the rule behind each answer

Sample 1 · North Carolina Cdl Classes Endorsements Restrictions Tests And Commerce Status

A power unit and trailer have a combined rating of 34,600 pounds. The trailer alone is rated at 12,200 pounds. Which license group applies?

  1. Class A, because the combination exceeds 26,000 pounds and the towed unit exceeds 10,000 poundsCorrect
  2. Class B, because every two-unit vehicle starts in the straight-truck group
  3. Class C, because only the trailer rating is considered
  4. No CDL, because the tractor rating is not independently above 26,000 pounds

Why: Class A, because the combination exceeds 26,000 pounds and the towed unit exceeds 10,000 pounds addresses the operating condition safely. Class A covers a combination rated at least 26,001 pounds when the towed vehicle or vehicles have a gross vehicle weight rating above 10,000 pounds.

Sample 2 · Speed Space Hazards Weather And Railroad Crossings

A car looks comfortably distant in a convex mirror, but it is actually close to the trailer. Which mirror limitation explains the error?

  1. Convex mirrors widen the view but make objects look smaller and farther awayCorrect
  2. Convex mirrors enlarge nearby vehicles and make them look closer
  3. Every convex image gives an exact distance without driver judgment
  4. Convex mirrors show only the roadway directly ahead of the truck

Why: Convex mirrors widen the view but make objects look smaller and farther away addresses the operating condition safely. Mirror checks should be brief, and convex mirrors require judgment because they make objects appear smaller and farther away than they are.

Sample 3 · Cargo Inspection Weight Balance And Securement

A shipper seals a trailer after its employees load it. What cargo-safety responsibility still belongs to the driver?

  1. The driver remains responsible for being satisfied that distribution and securement are safeCorrect
  2. The seal transfers all driving responsibility to the shipper
  3. The driver needs to consider cargo only after a roadside citation
  4. Cargo condition can never affect the driver of a sealed vehicle

Why: The driver remains responsible for being satisfied that distribution and securement are safe addresses the operating condition safely. Even when another person loads the vehicle, the driver remains responsible for inspection, overload and balance recognition, securement, clear visibility, and access to emergency equipment.

Sample 4 · Passenger Vehicle Inspection Loading And Operation

Yesterday's bus report notes a defective emergency-exit latch. What evidence must today's driver have before signing off?

  1. Proof that the bus completed yesterday's route despite the defect
  2. Nothing, because prior inspection reports never affect the next driver
  3. Confirmation that it was repaired or that the carrier determined immediate repair was unnecessaryCorrect
  4. A promise that no passenger will use that exit

Why: Confirmation that it was repaired or that the carrier determined immediate repair was unnecessary addresses the operating condition safely. A bus driver signs the previous driver's inspection report only after listed defects have been certified as repaired or certified as not requiring repair.

Sample 5 · Combination Vehicle Control Coupling And Inspection

Heavy coils are offset high on one side of a semitrailer. What loading change improves combination stability?

  1. Move every coil rearward without changing its height
  2. Leave the load unchanged and use abrupt steering to oppose lean
  3. Lower and center the coils while distributing weight rather than leaving a high side biasCorrect
  4. Stack them higher on the same side to keep tiedowns tight

Why: Lower and center the coils while distributing weight rather than leaving a high side bias addresses the operating condition safely. Combination cargo should be kept low, centered, and distributed because a high or side-biased center of gravity increases rollover risk.

Sample 6 · Hazardous Materials And School Bus Safety

A hazmat package is correctly listed on the paperwork but is visibly leaking. What must the driver do?

  1. Remove all placards so the leak does not need to be documented
  2. Place it by the cab and continue without notifying the carrier
  3. Refuse the defective package and accept only a properly prepared shipment with required papers and placardsCorrect
  4. Load it because paperwork always overrides physical package condition

Why: Refuse the defective package and accept only a properly prepared shipment with required papers and placards addresses the operating condition safely. The hazardous-material driver rejects leaking or improperly prepared packages, maintains required placards and papers, and transports the shipment safely after shipper and carrier checks.

What is on the test

The 10 topics the North Carolina CDL practice test covers

These are North Carolina's own topic areas, from north carolina cdl classes endorsements restrictions tests and commerce status to hazardous materials and school bus safety, each with 10 questions. Under each one are two questions from the bank, shown without their answers; the practice test explains every one of them.

  1. North Carolina Cdl Classes Endorsements Restrictions Tests And Commerce Status10 questions
    • A straight truck rated at 29,500 pounds pulls a utility trailer rated at 8,900 pounds. How is it classified?
    • A small activity bus is built for 15 passengers plus its driver and falls below the Class A and B weight levels. What CDL group can the seating capacity trigger?
  2. Vehicle Inspection Control Visibility And Communication10 questions
    • An inspector finds a cracked steering component before a scheduled run. Why can the vehicle be placed out of service?
    • Mid-trip, the driver notices a hot smell, a rising temperature gauge, and a new vibration. How should these clues be treated?
  3. Speed Space Hazards Weather And Railroad Crossings10 questions
    • Before moving one lane right in dense traffic, when should a commercial driver operate the turn signal?
    • A shower leaves the freeway glossy, and the steering begins to feel light over standing water. What is the proper speed response?
  4. Emergencies Abs Skids Crashes Fires And Driver Fitness10 questions
    • A box falls into the lane with no stopping room, but an open lane provides an escape. Which steering technique limits the chance of overturning?
    • A collision is imminent on dry pavement and all wheels are still rolling. How does controlled braking use available traction?
  5. Cargo Inspection Weight Balance And Securement10 questions
    • A flatbed begins a trip with freshly tightened tiedowns. By what point must its first on-road cargo check occur?
    • Following the initial check, which event can trigger another required look at cargo securement?
  6. Passenger Vehicle Inspection Loading And Operation10 questions
    • An exterior service panel is open as a bus prepares to merge into traffic. What is required first?
    • Packages occupy two seats and narrow the aisle leading to an emergency door. Which interior standard is violated?
  7. Air Brake Components Inspection And Use10 questions
    • Which pairing correctly states the jobs of the three air-brake subsystems?
    • Air pressure has dropped from the governor's cut-out setting. What event tells the compressor to begin pumping again?
  8. Combination Vehicle Control Coupling And Inspection10 questions
    • Why are sharp steering inputs especially hazardous when a combination has multiple trailing units?
    • A driver expects an empty combination to stop more easily than a loaded one in all conditions. What important exception challenges that assumption?
  9. Doubles Triples And Tank Vehicle Operation10 questions
    • A driver makes a quick steering correction while pulling doubles. Where is the crack-the-whip response most severe?
    • A twin-trailer set has one nearly full semitrailer and one lightly loaded semitrailer. Which should be closest to the tractor?
  10. Hazardous Materials And School Bus Safety10 questions
    • A driver stores hazardous-material papers in a closed sleeper drawer while underway. Why is that location unsuitable?
    • A shipping description lists the packing group first and the identification number last. What order should replace it?
How to prepare

A study plan for the North Carolina CDL knowledge test

1

Find out where you stand

Take a Quick check of 25 in coaching mode. Read each explanation, including the ones you got right; it tells you the rule North Carolina tests, not just the answer.

2

Study the topics you missed

Your account's Study tab ranks the 10 topics by your results. Read that chapter of the North Carolina Commercial Driver License Manual, then take another Quick check to confirm the gap has closed.

3

Rehearse the real thing

Take the Full challenge of 100 in exam mode. Aim for 80 percent or better twice in a row; at that point you are answering from the rules, not from memory of the questions.

Questions

North Carolina CDL practice test questions

Is this the official North Carolina CDL knowledge test?

No. DMV Exam Pass is an independent study service and is not affiliated with North Carolina Division of Motor Vehicles. The questions are written in the style of the exam to prepare you for it; the official test is taken with the agency.

What does the North Carolina CDL practice test cover?

The 100 questions are spread evenly across 10 topics: North Carolina Cdl Classes Endorsements Restrictions Tests And Commerce Status, Vehicle Inspection Control Visibility And Communication, Speed Space Hazards Weather And Railroad Crossings, Emergencies Abs Skids Crashes Fires And Driver Fitness, Cargo Inspection Weight Balance And Securement, Passenger Vehicle Inspection Loading And Operation, Air Brake Components Inspection And Use, Combination Vehicle Control Coupling And Inspection, Doubles Triples And Tank Vehicle Operation, and Hazardous Materials And School Bus Safety. Every test you take draws from all of them, so a weak area shows up quickly.

How many questions are in the practice test, and how long does it take?

The North Carolina bank holds 100 questions. A Quick check of 25 takes about ten minutes, a Practice run of 50 about twenty, and the Full challenge of 100 about forty. You can pause any time.

Are these the real questions from the North Carolina exam?

No. Nobody outside the agency has the real questions, and we do not use, claim, or advertise leaked or exact exam questions. These are independently written questions that test the same rules, so what you learn transfers to whatever the real test asks.

Which handbook should I study for the North Carolina CDL knowledge test?

The North Carolina Commercial Driver License Manual (2005 CDL Testing System (July 2014)), published by North Carolina Division of Motor Vehicles. Every question here is written for it, and each explanation names the rule, so when you miss a question you know which chapter to read.

What is the difference between coaching mode and exam mode?

Coaching mode shows whether each answer was right, and why, before you move on; it is for learning. Exam mode holds the explanations and the correct choices until the end and still shows your running score; it is for checking readiness. Both draw from the same bank, and scoring happens on our servers, so no answer key is loaded in your browser.

Does the practice test include road signs and pictures?

Yes. 1 of the 100 questions are illustrated with a sign, signal, marking, or road scene, the way the CDL knowledge test presents them.

Is the North Carolina practice test free, and do I need an account?

It is free, with no sign-up. An optional account saves your progress across devices and shows which topics need work.

Can I pause and come back later?

Yes. A test in progress is saved on this device and offered again when you return. With an account, it is saved to your account as well, so you can continue on another device.

What score should I aim for before test day?

Aim for 80 percent or better on a Full challenge in exam mode, more than once. The official passing score is set by the agency; scoring consistently above 80 here means you are answering from the rules rather than from luck.
