Tennessee's learner's permit test covers road signs, right-of-way rules, and safe driving practices
The Tennessee learner's permit knowledge test is administered by the Department of Safety and Homeland Security's Driver Services division. You will answer 30 multiple-choice questions on a computer at a Driver Services office. You need to score at least 24 correct answers (80 percent) to pass. The test draws from the Tennessee Driver's Handbook, which is free and available online at the Driver Services website.
The test is not timed, though most people finish in 20 to 30 minutes. You can take it as many times as you need if you do not pass on your first attempt. There is a fee each time you test — currently $15 for the knowledge test — though this amount can change. You must bring a valid photo ID and proof of your Social Security number or an Individual Taxpayer Identification Number.

The three main content areas on the test
Road signs and markings make up a significant portion of the test. You will see questions about what different colored signs mean (red, yellow, white, green, blue), what shapes signal what information (octagon for stop, triangle for yield), and what road markings tell you to do. For example, a solid yellow line on your side means you cannot pass, while a dashed yellow line means passing is allowed if it is safe.
Traffic laws and right-of-way rules are the second major area. These questions test whether you know when to yield at intersections, how to handle four-way stops, what to do at a red light with an arrow, and who has the right of way in common situations. You will also see questions about speed limits in different zones — school zones, residential areas, and highways — and what the default speed limit is on Tennessee roads when no sign is posted.
Safe driving practices and vehicle operation round out the test. This includes questions about seat belt use, following distance, how to handle skids or hydroplaning, what to do if your brakes fail, and the effects of alcohol and drugs on driving. You may also see questions about headlight use, when to use turn signals, and how to properly adjust mirrors.
How the test questions are structured
Each question presents a scenario or asks a direct question, followed by four answer choices. You select one answer on the computer screen. The questions do not require you to rank answers or select multiple correct responses — each question has one right answer.
Some questions show a picture of a road sign or road situation and ask what it means or what you should do. Others are text-only and describe a driving scenario. For example, you might see a picture of a yield sign and be asked what it means, or you might read a description of an intersection and be asked who has the right of way.
The test does not show you your score when ready after you finish. The Driver Services office staff will tell you whether you passed or failed before you leave. If you pass, you will receive your learner's permit that day. If you fail, you can schedule another test appointment, though some offices require you to wait a certain number of days before retesting.
Topics covered in detail on the test
Road signs by color and shape: Red signs (stop, do not enter, wrong way), yellow signs (warning), white signs (regulatory), green signs (direction), and blue signs (services). Diamond-shaped yellow signs warn of hazards ahead. Rectangular signs give information or rules.
Right-of-way at intersections: At a four-way stop, the first vehicle to stop has the right of way. If two vehicles stop at the same time, the vehicle on the right has the right of way. At a T-intersection, the vehicle on the through road has the right of way over the vehicle on the stem of the T.
Speed limits and zones: Tennessee's default speed limit on rural highways is 55 mph unless posted otherwise. In school zones during school hours, the limit is typically 25 mph. In residential areas, the limit is often 25 or 30 mph. On interstate highways, the limit is 70 mph for cars and 65 mph for trucks.
Seat belts and child safety: All front-seat passengers must wear seat belts. Children under a certain age or weight must use an appropriate car seat or booster seat. The test will ask about these requirements and why they matter.
Impaired and distracted driving: Questions cover the effects of alcohol, drugs, and fatigue on driving ability. You will also see questions about cell phone use while driving and why distraction is dangerous.
How to study for the test
The Tennessee Driver's Handbook is your primary study resource. It is available as a free PDF on the Driver Services website and covers every topic that appears on the test. Read through the entire handbook at least once, paying close attention to sections on road signs, traffic laws, and safe driving practices.
After reading the handbook, use practice tests to identify weak areas. Many online resources offer Tennessee-specific practice questions. Take several practice tests under conditions similar to the real test — sit at a computer, answer questions without looking back at notes, and time yourself to get used to the pace. If you score below 80 percent on a practice test, go back to the handbook and review that topic.
Focus extra study time on road signs and right-of-way rules, as these appear frequently on the test. Draw or print out pictures of signs and quiz yourself until you can identify them when ready. For right-of-way scenarios, write out the rule in your own words to make sure you understand it, not just memorize it.
What happens after you pass or fail
If you pass the knowledge test, you will receive your Tennessee learner's permit on the same day. Your permit is valid for five years. With a learner's permit, you can drive only when a licensed driver who is at least 21 years old is in the front passenger seat. You must follow all traffic laws and cannot drive between midnight and 5 a.m.
If you fail, you can retake the test. There is no mandatory waiting period between attempts at most Driver Services offices, though you will pay the $15 fee each time. Some offices may require you to wait a few days before scheduling your next test. When you retake the test, you will answer a different set of 30 questions drawn from the same content areas.
After you hold your learner's permit for a certain period and meet other requirements, you can take the road test to earn your full driver's license. The road test is separate from the knowledge test and is administered by a Driver Services examiner.
Common mistakes people make on the test
Rushing through questions is one of the most common errors. Even though the test is not timed, reading each question carefully and all four answer choices before selecting one reduces careless mistakes. A question might ask what you should do, and one answer choice might describe what you should not do — reading carefully prevents choosing the wrong answer.
Confusing similar road signs is another frequent mistake. Yellow warning signs look similar to each other, and red regulatory signs can be confused if you do not pay close attention to the specific symbol or text on each one. Spend time studying sign differences during your preparation.
Misunderstanding right-of-way rules at complex intersections trips up many test-takers. If a practice test shows you are weak in this area, draw diagrams of intersections and work through the rules step by step. Do not just memorize answers — understand the logic behind each rule.
Frequently Asked Questions
Can I bring notes or study materials into the testing room?
No. You cannot bring the handbook, notes, or any study materials into the testing room. You must answer all questions from memory. You can review the handbook before your test appointment, but once you enter the testing area, only you and the computer are allowed.
What if I fail the test — how soon can I retake it?
Most Tennessee Driver Services offices allow you to retake the test when ready or within a few days. Call your local Driver Services office to ask about their specific retesting policy. Each attempt costs $15. You will answer a different set of 30 questions each time you test.
Are the practice tests online the same as the real test?
Practice tests online cover the same topics and use the same question format as the real test, but they are not the exact same questions. The real test draws from a larger question bank, so you may see different scenarios. Use practice tests to learn the material and identify weak areas, not to memorize specific answers.
Do I need to pass the knowledge test before I can take the road test?
Yes. You must pass the knowledge test first and hold a valid learner's permit before you can schedule a road test. The road test is a separate exam where a Driver Services examiner watches you drive and evaluates your ability to operate the vehicle safely.
What if I do not understand a question on the test?
You can raise your hand and ask the test administrator for clarification on what a question is asking, though they cannot tell you the correct answer or explain the content. If you are unsure between two answers, select the one that seems most correct based on what you studied, and move on.
