Sample questions

Six questions from the Kentucky bank, with the rule behind each answer

Sample 1 · Kentucky Cdl Classes Endorsements Training And Driver Duties

A Kentucky combination has a 31,500-pound GCWR, and its semitrailer alone is rated at 11,200 pounds. Into which CDL class does that vehicle fall?

  1. Class ACorrect
  2. Class B based only on the power unit
  3. Class C despite the combination rating
  4. No commercial class because the trailer is separate

Why: The Kentucky manual locator supports this result: 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. Therefore, the proposed response is "Class A".

Sample 2 · Speed Space Hazards Weather And Railroad Crossings

A motorcycle seems distant in a convex mirror while a truck prepares to merge. What distance error must the driver allow for?

  1. The car may be closer than the mirror image suggestsCorrect
  2. The sedan must already be outside every blind area
  3. The convex surface displays exact distance
  4. A small image proves the sedan is pulling away

Why: The Kentucky manual locator supports this result: Mirror checks should be brief, and convex mirrors require judgment because they make objects appear smaller and farther away than they are. Therefore, the proposed response is "The car may be closer than the mirror image suggests".

Sample 3 · Cargo Inspection Weight Balance And Securement

A warehouse crew loads and seals a trailer before the driver arrives. Which cargo-safety duties still belong to the person who will operate the vehicle?

  1. Confirm the cargo is safe within the driver's inspection and securement dutiesCorrect
  2. Transfer every road-safety duty to the loading crew
  3. Assume balance is safe because the doors are sealed
  4. Leave the decision entirely to a future roadside officer

Why: The Kentucky manual locator supports this result: 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. Therefore, the proposed response is "Confirm the cargo is safe within the driver's inspection and securement duties".

Sample 4 · Passenger Vehicle Inspection Loading And Operation

An incoming coach driver sees an unrepaired emergency-exit defect on the previous inspection report. When may the driver sign that report?

  1. Accept the defect because boarding has started
  2. Treat it as solely the previous driver's responsibility
  3. No, wait for the required repair or no-repair certificationCorrect
  4. Sign first and let the signature serve as repair proof

Why: The Kentucky manual locator supports this result: 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. Therefore, the proposed response is "No, wait for the required repair or no-repair certification".

Sample 5 · Combination Vehicle Control Coupling And Inspection

Dense pallets are concentrated high along the right wall of a semitrailer. Where should they be moved to improve rollover resistance?

  1. Put every item behind the rearmost axle
  2. Use extra steering instead of redistributing freight
  3. Move the heavy cargo lower and toward the centerCorrect
  4. Move the dense load higher and farther left

Why: The Kentucky manual locator supports this result: Combination cargo should be kept low, centered, and distributed because a high or side-biased center of gravity increases rollover risk. Therefore, the proposed response is "Move the heavy cargo lower and toward the center".

Sample 6 · Hazardous Materials And School Bus Safety

A hazmat package has correct paperwork but leaks through a damaged seam. What acceptance decision belongs to the driver?

  1. Carry the damaged package inside the cab
  2. Position a placard so the leak cannot be seen
  3. Reject the leaking packageCorrect
  4. Load it because its documents are correct

Why: The Kentucky manual locator supports this result: 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. Therefore, the proposed response is "Reject the leaking package".

What is on the test

The 10 topics the Kentucky CDL practice test covers

These are Kentucky's own topic areas, from kentucky cdl classes endorsements training and driver duties 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. Kentucky Cdl Classes Endorsements Training And Driver Duties10 questions
    • A box truck carries a 28,500-pound GVWR and is not towing another unit. Which commercial license class covers that straight vehicle?
    • A hotel shuttle weighs below the Class A and B thresholds but was built with 16 seating positions counting the driver. Why is it still a CDL vehicle?
  2. Vehicle Inspection Control Visibility And Communication10 questions
    • A cracked steering component is discovered before a delivery truck leaves Louisville. What is the immediate safety value of finding it during inspection?
    • Mid-route, a driver hears a new metallic scrape even though no dashboard warning appears. How should that sound influence the next equipment decision?
  3. Speed Space Hazards Weather And Railroad Crossings10 questions
    • A tractor is approaching a right turn. Which signaling pattern communicates the maneuver and avoids misleading traffic afterward?
    • Rainwater builds across the lane and the tires begin to lose road feel. Which two effects should cause an immediate speed reduction?
  4. Emergencies Abs Skids Crashes Fires And Driver Fitness10 questions
    • A disabled car blocks the lane too close for a full stop, and an open shoulder provides an escape. How should the driver steer through and out of the avoidance path?
    • Heavy braking without ABS locks the wheels during an emergency. What control change allows the driver to recover steering and continue stopping?
  5. Cargo Inspection Weight Balance And Securement10 questions
    • A shipment was checked at departure and the truck is now 41 miles into the trip. By what point must the driver inspect its securement again?
    • A driver stops after three hours, although only 138 miles have passed since the prior cargo inspection. Is another load check due?
  6. Passenger Vehicle Inspection Loading And Operation10 questions
    • A luggage-bay access door remains unlatched after the walk-around. What must happen before the bus enters traffic?
    • The seats are tight, but baggage blocks half the center aisle and an exit indicator does not work. How should the bus be treated?
  7. Air Brake Components Inspection And Use10 questions
    • A mechanic describes normal stopping, holding a parked vehicle, and responding to system failure. Which three air-brake systems perform those jobs?
    • Air pressure drops to the governor's lower control point after several brake applications. What should the compressor do next?
  8. Combination Vehicle Control Coupling And Inspection10 questions
    • A quick steering input at the tractor produces a larger swing at the rear trailer. What combination-vehicle effect explains the change?
    • An unloaded tractor is traveling without a trailer on damp pavement. Why may its powerful brakes and stiff suspension make smooth stopping difficult?
  9. Doubles Triples And Tank Vehicle Operation10 questions
    • A triple combination enters a curve. Which trailer is exposed to the largest crack-the-whip movement and therefore the greatest rollover danger?
    • A twin set includes one empty trailer and one carrying a dense shipment. How should the two be ordered behind the tractor?
  10. Hazardous Materials And School Bus Safety10 questions
    • Emergency crews may need hazmat shipping papers after the driver leaves the cab. Where must the papers be kept during travel?
    • A shipping clerk is arranging the basic description for a regulated material. What sequence should begin the entry?
How to prepare

A study plan for the Kentucky 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 Kentucky 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 Kentucky Commercial Driver's 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

Kentucky CDL practice test questions

Is this the official Kentucky CDL knowledge test?

No. DMV Exam Pass is an independent study service and is not affiliated with Kentucky State Police. 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 Kentucky CDL practice test cover?

The 100 questions are spread evenly across 10 topics: Kentucky Cdl Classes Endorsements Training And Driver Duties, 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 Kentucky 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 Kentucky 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 Kentucky CDL knowledge test?

The Kentucky Commercial Driver's License Manual, published by Kentucky State Police. 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 Kentucky 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.
