Kentucky CDL permit test: what to expect
The written exam most people call the Kentucky CDL permit test is the general knowledge test, and passing it is what gets you a commercial learner's permit rather than the license itself. You need 80% to pass, a federal standard that is the same in every state. The number of questions is set by Kentucky, and our practice tests use the common 50-question format.
Once you hold the permit you have to keep it for at least 14 days before you are allowed to attempt the skills test, so it is worth sitting the written exam as early as you can. Practice below until you are clearing Kentucky's standard comfortably rather than scraping it.

5 Kentucky CDL Practice Questions and Answers
Here are 5 sample Kentucky general knowledge questions with the right answer and a quick explanation for each. Read through them, then take the quiz above to see how you do without looking.
1. When driving around a curve, where should your visual attention be directed?
- A. Immediately in front of your front bumper.
- B. At the inside edge of the road surface only.
- C. Across the curve as far as you can see to anticipate hazards, oncoming traffic, and judge the sharpness. (correct answer)
- D. In the rearview mirror to watch the trailer tracking.
Why: Looking through the curve allows you to see the path ahead, spot obstacles early, and smoothly adjust your steering and speed.
2. What is a hidden hazard of driving through a deep puddle of water?
- A. The water can wash away the paint on your bumper.
- B. Water can get into the brake drums, causing the brakes to become weak or pull to one side. (correct answer)
- C. The puddle may contain fish that damage your radiator.
- D. The puddle will freeze your tires to the pavement instantly.
Why: Driving through deep water can cause your brake drums to get wet. Wet brakes are less effective and can apply unevenly, causing the vehicle to pull to one side or not stop in time.
3. Why should you never attempt to start moving a heavy commercial vehicle in a high gear?
- A. It will cause the engine to over-rev
- B. It can cause severe damage to the clutch and drivetrain (correct answer)
- C. It engages the clutch brake prematurely
- D. The air brakes will automatically lock
Why: Starting in a high gear requires excessive slipping of the clutch, which generates immense heat and will quickly burn out the clutch disc.
4. How does an automatic transmission compare to a manual transmission regarding engine braking on a downgrade?
- A. Automatic transmissions provide no engine braking
- B. Automatic transmissions downshift automatically to the safest gear on downgrades
- C. You must manually select a lower range in an automatic transmission to get the same engine braking effect (correct answer)
- D. Automatic transmissions provide superior engine braking without driver input
Why: In an automatic transmission, the driver must manually select a lower range to effectively utilize engine braking, similar to a manual transmission.
5. When attempting to pass another vehicle at night, you should:
- A. Turn off your headlights so they don't see you coming
- B. Signal early, check your mirrors frequently, and ensure you have enough clear distance (correct answer)
- C. Tailgate them closely until they pull over
- D. Flash your high beams continuously during the entire pass
Why: Passing at night is dangerous due to limited visibility. You must signal early, check blind spots, and be absolutely certain there is no oncoming traffic hidden in the darkness.
