What the Louisville Knowledge Test Covers and How It Works
Kentucky's written knowledge test in Louisville is administered by the Kentucky Transportation Cabinet at any of the state's driver licensing offices. The test covers road signs, traffic laws, safe driving practices, and right-of-way rules specific to Kentucky. You will answer 40 multiple-choice questions on a computer or paper form, depending on the testing location.
You must score at least 32 correct answers (80 percent) to pass. The test takes about 15 to 20 minutes to complete. If you fail, you can retake it the same day at most Louisville locations, though you may have to wait and pay the retest fee again.
The test is offered in English and Spanish. If you need the test in another language, contact the Louisville Regional Office of the Kentucky Transportation Cabinet ahead of time to arrange an interpreter or translated materials.

Where to Take the Test in Louisville
The main Louisville driver licensing office is located at 1025 Bardstown Road, Louisville, KY 40204. This is the busiest location in the area and handles knowledge tests, road tests, and license renewals. Hours are typically Monday through Friday, 8:00 a.m. to 4:30 p.m., and Saturday 8:00 a.m. to 12:00 p.m., though hours vary by season and staffing.
There is also a satellite office in the East End area that offers limited services. Call ahead to confirm that the location you plan to visit offers knowledge testing on the day you want to go. Wait times at the main Bardstown Road office can exceed two hours during peak times (late morning and early afternoon on weekdays).
You do not need an appointment for the knowledge test at most Louisville locations, but arriving early in the morning or on a weekday afternoon typically means shorter waits. Some locations now offer online scheduling through the Kentucky Transportation Cabinet website; check before you go.
Documents You Must Bring
Bring a valid form of government-issued photo identification. Acceptable documents include a passport, military ID, state ID card, or an out-of-state driver's license. A school ID, library card, or work badge will not be accepted.
You will also need to provide your Social Security number or an Individual Taxpayer Identification Number (ITIN). Have this memorized or written down; you will enter it into the system before the test begins.
If you are under 18, bring a parent or legal guardian with you. They must sign consent forms before you can test. Bring the original or certified copy of your birth certificate as well.
What the Test Questions Look Like
Kentucky knowledge test questions are straightforward and based directly on the Kentucky Driver's Manual. You will see questions about speed limits in residential areas, what to do at a four-way stop, how to read common road signs, and rules for passing, turning, and parking.
Example questions include: "What does a yellow diamond-shaped sign mean?" (warning), "When must you use your headlights?" (30 minutes after sunset), and "At a red light, can you turn right if no traffic is coming?" (yes, unless a sign says no right turn on red). Each question has four answer choices.
The test does not include trick questions or questions about local Louisville ordinances. It focuses on statewide Kentucky traffic laws and universal driving safety. If you study the official Kentucky Driver's Manual cover to cover, you will recognize nearly every question on the test.
How to Study and Prepare
The Kentucky Driver's Manual is the only study material you need. It is available free online at the Kentucky Transportation Cabinet website (transportation.ky.gov) and in print at any driver licensing office. The manual is about 60 pages and covers all topics tested on the knowledge exam.
Read the manual at least twice before testing. On your first read, go straight through. On your second read, focus on sections you found confusing. Pay special attention to road signs (Chapter 2), right-of-way rules (Chapter 3), and speed limits and parking (Chapter 4).
Many people use online practice tests to drill questions. The Kentucky Transportation Cabinet does not publish an official practice test, but several third-party websites offer free Kentucky knowledge test simulators. These are helpful for building confidence, but remember that the real test questions come directly from the manual, so reading the manual is more important than taking practice tests.
Common Mistakes That Cause Failures
The most common reason people fail is not reading the Kentucky Driver's Manual before testing. They rely on general driving knowledge or assume they know the rules already. Kentucky has specific rules about right-of-way, speed limits in school zones, and when to use headlights that differ slightly from other states. If you learned to drive in another state, you must study the Kentucky manual.
Another frequent mistake is rushing through the test. You have 15 to 20 minutes to answer 40 questions, which gives you plenty of time. Read each question carefully and all four answer choices before selecting your answer. If you are unsure, skip the question and come back to it at the end.
Some test-takers also misread road sign questions. Study the signs in the manual carefully and learn what each color and shape means. Yellow means warning, red means stop or do not enter, white means regulation, and green means direction or permission.
What Happens After You Pass
Once you pass the knowledge test, you will receive a Certificate of Passage or a stamp in your test record. This is valid for 12 months. You must then schedule and pass the road skills test (the driving test) before your certificate expires.
If you do not take the road test within 12 months of passing the knowledge test, you will have to retake the knowledge test. The road test is scheduled separately and is administered by a Kentucky Transportation Cabinet examiner. You will drive your own vehicle (or a vehicle provided by the testing location) on public roads in the Louisville area.
After you pass both the knowledge test and the road test, you will pay the license fee and receive your Kentucky driver's license. Standard licenses are valid for five years; REAL ID-compliant licenses are also available and required for federal purposes like air travel.
Frequently Asked Questions
Can I take the knowledge test online from home in Louisville?
No. Kentucky requires all knowledge tests to be taken in person at a driver licensing office. You cannot take it remotely or by mail. You must go to the Bardstown Road office or another authorized testing location in the Louisville area.
What if I fail the test? Can I retake it right away?
Yes. Most Louisville locations allow you to retake the test the same day if you fail. You will pay the retest fee again (the fee varies but is typically $5 to $10). You do not have to wait days or weeks between attempts, though some offices may have a short waiting period between tests.
Is the test different if I am getting a commercial driver's license?
Yes. Commercial driver's license (CDL) knowledge tests are longer and cover additional topics like air brakes, hazardous materials, and large vehicle handling. If you are testing for a CDL, you will take a different, more difficult exam. Confirm which test you need before you arrive.
Do I need to bring my Social Security card to the test?
No. You do not need to bring the physical card. You only need to know your Social Security number and provide it when you register for the test. Bring a photo ID instead.
What if I do not pass after multiple attempts?
Kentucky does not limit the number of times you can retake the knowledge test. You can keep retaking it until you pass. However, each attempt costs a fee. If you are struggling, spend more time studying the Kentucky Driver's Manual and consider using online practice tests to identify weak areas before your next attempt.
