Tennessee's permit test has 30 questions, and you need to answer at least 24 correctly to pass
The Tennessee written permit test, officially called the Knowledge Test, contains exactly 30 multiple-choice questions. Each question has four possible answers. To pass, you must score at least 80 percent, which means getting 24 or more questions right. You have up to one hour to complete the test, though most people finish in 20 to 30 minutes.
The test covers information from the Tennessee Driver Handbook, which the Department of Safety and Homeland Security publishes. You can read the handbook online for free on their website before you take the test. The questions focus on road signs, traffic laws, safe driving practices, and what to do in different driving situations.

What the test covers
The 30 questions come from several main topics. You will see questions about road signs and what they mean, traffic laws and speed limits, right-of-way rules, parking rules, and how to handle emergencies or bad weather. The test also includes questions about impaired driving, distracted driving, and the consequences of traffic violations.
Questions are drawn from the Tennessee Driver Handbook, so studying that handbook is the most direct way to prepare. The handbook explains each topic in plain language and includes pictures of road signs. You do not need to memorize every detail — the test focuses on the most important safety information that affects how you drive.
Where you take the test
You take the permit test at a Driver Services Center run by the Tennessee Department of Safety and Homeland Security. There are centers in most counties across the state. You can find the location nearest you and their hours on the department's website.
When you arrive, bring your Social Security number, proof of your date of birth (such as a birth certificate), and proof of your current address (such as a utility bill or lease). The staff will verify your information, then you will sit at a computer or paper station to take the test. The test is administered in English, but some locations may offer it in other languages — call ahead to ask.
How the test is scored
Your score is calculated when ready after you finish. The system counts how many questions you answered correctly and tells you whether you passed or failed. A passing score is 24 out of 30 questions. If you pass, you can move forward with getting your permit. If you do not pass, you will receive a score report showing which topics gave you trouble.
The score report does not tell you which specific questions you missed, but it does show which subject areas you should study more. For example, it might show that you need to review road signs or right-of-way rules. You can use this feedback to focus your studying before you retake the test.
Retaking the test if you do not pass
If you do not pass on your first try, you can retake it. The waiting period between attempts varies by location — some Driver Services Centers let you retake it the same day, while others require you to wait a day or longer. Call the center where you plan to test to find out their specific policy.
Each time you retake the test, you pay the same fee as the first attempt. There is no limit to how many times you can retake it, so you can keep trying until you pass. Most people who study the handbook pass on their second attempt if they did not pass the first time.
How to prepare for the test
The Tennessee Driver Handbook is your main study resource. Read through it at least once before you take the test, paying special attention to road signs, speed limits, and right-of-way rules. These topics appear frequently on the test. You can read the handbook as a PDF or read it online on the Department of Safety and Homeland Security website.
Practice tests can help you get used to the format and see what kinds of questions appear. Some practice tests are available online through the state website or through third-party sites. Taking a practice test shows you which topics you understand well and which ones need more study. Even if a practice test has different questions than the real test, it helps you learn the material and build confidence.
Frequently Asked Questions
Can I take the permit test online from home?
No. Tennessee requires you to take the test in person at a Driver Services Center. You cannot take it online or by mail. You must go to a center, bring your identification documents, and take the test there.
What happens if I fail the test?
You receive a score report showing which topics you should study more. You can retake the test after waiting the required time at your local Driver Services Center. There is no limit to how many times you can retake it, and each attempt costs the same fee.
Do I need to study the entire handbook or just certain sections?
The test draws from the whole handbook, so studying all of it gives you the best chance to pass. However, road signs, right-of-way rules, and traffic laws appear most often. If you are short on time, focus on those sections first, then read the rest.
Is the permit test the same as the driver's license test?
No. The permit test is the written knowledge test you take first. After you get your permit and practice driving, you take a separate road test with an examiner who watches you drive. Both tests must be passed to get your license.
Can I bring notes or the handbook into the test room?
No. The test is closed-book, meaning you cannot use any materials during the test. You must study and memorize the information beforehand. The Driver Services Center staff will not allow notes, phones, or the handbook in the testing area.
