What the Kentucky written test covers and how it is scored
Kentucky's written knowledge test has 40 questions drawn from the Kentucky Driver's Manual. You must answer at least 32 questions correctly to pass — that is 80 percent. The test covers road signs, right-of-way rules, speed limits, parking, seat belt laws, and what to do at traffic lights and stop signs. Questions are multiple choice with four answer options each.
The test is administered on a computer at any Kentucky Transportation Cabinet Driver Licensing office. You take it on the same day you come in for your appointment. There is no separate scheduling for the written test itself — it happens as part of your license transaction. The test takes most people 20 to 30 minutes to complete.
Your score appears on screen when ready after you finish. If you pass, you move forward to the road test (if you are a new driver) or to payment and photo. If you do not pass, you can retake the test the same day, but you must pay the test fee again. Most offices allow you to retake it within the same visit, though some require you to schedule a new appointment.
Key Takeaways
- You need a score of at least 32 out of 40 questions correct to pass the Kentucky written test.
- All questions come from the Kentucky Driver's Manual, which is free to read or pick up at any DMV office.
- The test is computer-based and takes 20 to 30 minutes; you get your score when ready.
- If you fail, you can retake the test the same day for an additional fee, or schedule a new appointment depending on your local office policy.
- You must bring a valid ID and proof of residency to your appointment; without these, you cannot take the test.
How to study using the Kentucky Driver's Manual
The Kentucky Driver's Manual is your only study resource you need. Every question on the written test comes directly from this manual. You can read it free from the Kentucky Transportation Cabinet website, or pick up a printed copy at any Driver Licensing office. The manual is organized by topic: traffic signs, road rules, parking, pedestrians, and special situations like driving in bad weather or around school buses.
Read the manual section by section rather than skimming. Pay close attention to the sign recognition section — the test includes real images of road signs, and you must know what each one means and what action it requires. For example, you need to know the difference between a yield sign and a stop sign, and what a diamond-shaped yellow sign means versus a rectangular white sign.
Take notes on rules that surprise you or that differ from what you thought you knew. Common trouble spots include Kentucky's specific speed limits in school zones (20 mph when children are present), right-of-way at four-way stops, and when you can and cannot pass another vehicle. Write these down and review them the night before your test.
Common mistakes on the Kentucky test and how to avoid them
The most frequent error is misreading the question. Test questions sometimes ask what you should NOT do, or what happens in a specific weather condition. Read the entire question and all four answer choices before you select. If a question says "Which of the following is NOT allowed," make sure you pick the action that is prohibited, not the one that is permitted.
Another common mistake is confusing speed limits. Kentucky has different limits for residential areas (25 mph unless posted otherwise), rural highways (55 mph), and interstate highways (65 to 70 mph depending on the road). The test includes questions about what speed is legal in each zone. Memorize these numbers exactly as they appear in the manual.
A third mistake is getting right-of-way rules wrong at intersections. Many people guess on questions about who goes first at a four-way stop or when two cars approach an uncontrolled intersection at the same time. The rule is: the car on the right has the right of way. If you are both coming from the same direction, the car going straight has the right of way over the car turning. Study the right-of-way section of the manual twice.
What to bring and what to expect on test day
Bring one valid photo ID (a passport, military ID, or out-of-state driver license) and one proof of Kentucky residency. Proof of residency can be a utility bill, lease agreement, bank statement, or government mail with your name and current address. Both documents must be original or certified copies — photos or faxes are not accepted. If you do not have both documents, you cannot take the test and will need to reschedule.
Arrive at least 15 minutes before your appointment time. The office will check your documents, verify your identity, and take your photo. Then you will be directed to a computer terminal to take the written test. You cannot bring notes, phones, or study materials into the testing area. You also cannot wear a hat or sunglasses during the test.
The computer will display one question at a time. You can review your answers before you submit the test, and you can go back and change an answer if you want to. Once you submit, your score is final and appears on screen. If you pass, the office will tell you what happens next — either scheduling your road test or moving to payment and licensing.
Retaking the test if you do not pass on your first attempt
If you score below 32 out of 40, you have not passed. You can retake the test when ready at most Kentucky offices, but you must pay the test fee again. The fee varies by county but is typically between $10 and $15. Ask the office staff whether you can retake it the same day or whether you need to schedule a new appointment.
Before you retake the test, spend time reviewing the sections of the manual where you struggled. If you failed questions about signs, go back to the sign section and study each one. If you missed questions about speed limits or right-of-way, focus there. Do not straightforward retake the test without studying — the questions are drawn from the same manual, and the same gaps in your knowledge will likely cause you to fail again.
You can retake the test as many times as you need to pass. There is no limit on the number of attempts in Kentucky. Each attempt costs the test fee, so budget for that if you think you may need more than one try.
Differences between the standard test and the CDL knowledge test
If you are testing for a Commercial Driver License (CDL), the written test is different and much longer. The CDL test has 50 questions and covers air brakes, hazardous materials, passenger safety, and large vehicle operation. You must score at least 40 out of 50 to pass. The CDL manual is separate from the standard driver manual and covers these commercial topics in detail.
The CDL test is also computer-based and administered at the same Driver Licensing offices, but you must pass the standard knowledge test first if you do not already have a valid driver license. If you already hold a Kentucky driver license, you can go straight to the CDL test. Study the CDL manual thoroughly — the questions are more technical and require understanding of vehicle systems and safety regulations specific to commercial driving.
Frequently Asked Questions
Can I take the written test online or by mail?
No. Kentucky requires you to take the written test in person at a Driver Licensing office on a computer terminal. You cannot take it online, by mail, or at home. You must schedule an appointment and appear at the office on the date and time you book.
What happens if I fail the written test three times?
Kentucky does not impose a limit on retakes. You can retake the test as many times as you need. Each attempt requires paying the test fee again. If you keep failing, spend more time studying the manual and consider asking someone to quiz you on the material before your next attempt.
Is the written test given in languages other than English?
Kentucky offers the written test in English only. If you need language support, you may bring a certified interpreter to the office, but the test itself will be in English. Contact your local Driver Licensing office in advance if you need an interpreter so they can arrange for one.
How long is the written test score valid if I pass?
Your passing score is valid for 12 months from the date you pass. If you pass the written test but do not complete your road test or finish your license transaction within that year, you will need to retake the written test. Schedule your road test as soon as possible after passing the written test.
Can I see which questions I missed after I take the test?
No. Kentucky does not provide a detailed breakdown of which questions you missed or why. You only see your overall score. If you fail and retake the test, review the entire manual again rather than trying to guess which topics gave you trouble.
