What the Tennessee F Endorsement Test Covers
Tennessee's F endorsement allows you to haul for-hire vehicles — meaning you can charge passengers or freight owners for transportation. The written test for this endorsement covers the rules specific to commercial driving: how to load cargo safely, what weight limits explore, how to inspect a vehicle before a trip, and what logbook entries you need to keep.
The test itself is 20 questions, and you need to answer at least 16 correctly to pass. You take it at your local Driver Services Center after you have already passed your regular written test and obtained your learner's permit. The F endorsement test is separate from the road test — you will take both before you can get your full commercial license.
Unlike the general knowledge test, the F endorsement focuses on practical safety and legal requirements you will actually follow on the job. The questions are straightforward: they ask what you should do in a specific situation, not trick questions or edge cases.

Where to Find Official Tennessee F Endorsement Study Material
The Tennessee Commercial Driver License Manual is the official source for everything on the F endorsement test. You can read it free from the Tennessee Department of Safety and Homeland Security website. The manual breaks down each topic — cargo handling, vehicle maintenance, hours of service, and more — with examples and explanations.
Read through the sections that explore to the F endorsement. The manual is written for people taking the test, so it does not assume you already know the material. Take notes on anything that seems unfamiliar, and go back to those sections when you practice.
The official manual is also what the test writers use to create the actual questions. If you understand the manual, you understand what the test will ask.
How Practice Tests Help You Prepare
A practice test shows you the format and style of the real test before you take it. You will see how questions are worded, what kinds of scenarios they describe, and how the answer choices are structured. This familiarity reduces anxiety on test day and helps you work through questions faster.
Practice tests also reveal gaps in your knowledge. If you miss several questions about weight limits or logbook rules, you know to spend more time on those sections of the manual. You can take a practice test more than once — retake it a few days later to see if you have improved.
The goal is not to memorize the practice test. The goal is to use it as a tool to find weak spots and build confidence with the real material.
What to Study Before Taking a Practice Test
Read the relevant sections of the Tennessee Commercial Driver License Manual first. Do not jump straight to a practice test without any background. You will learn more if you understand the concepts before you see the questions.
Focus on these core topics: how to inspect a commercial vehicle before driving, weight and load limits, how to find cargo, hours of service rules, and what goes in a logbook. These topics appear repeatedly on the test because they are the foundation of safe commercial driving.
If you have access to a commercial vehicle, walk through an actual pre-trip inspection while you study. Seeing the real vehicle and touching the parts you are learning about makes the material stick better than reading alone.
Taking the Practice Test and Reviewing Your Answers
Take the practice test in a quiet place without distractions, just like you will on test day. Set a timer — you will have a limited amount of time on the real test, so practicing under time pressure helps. Do not look at the manual or your notes while you are taking the test.
When you finish, check your answers against the answer key. For every question you missed, go back to the manual and find the section that covers that topic. Read it again and understand why the correct answer is right. Write down the rule or concept so you remember it next time.
If you scored below 80 percent, study the weak areas and take the practice test again in a few days. You should see improvement the second time. Once you are consistently scoring 80 percent or higher, you are ready for the real test.
The Difference Between Practice Tests and the Real Test
Practice tests are designed to match the real test in format and difficulty, but they are not identical. The real test may include questions that are worded slightly differently or cover edge cases you did not see in practice. This is normal and not a sign that you are unprepared.
The real test is also taken on a computer at the Driver Services Center, not on paper or on your phone. If you have not used a computer-based test before, ask the staff at the center to show you how it works when you arrive. They can walk you through the basics so you are not learning the system on test day.
One advantage of the real test: you can flag questions and come back to them if you have time left. On a practice test, you may not have that option, so do not assume the real test will work exactly the same way.
How Often You Can Retake the F Endorsement Test
If you do not pass the F endorsement test on your first try, you can retake it. Tennessee allows you to test again after a waiting period — check with your local Driver Services Center for the exact timeline, as it may vary by location.
Use the time between tests to study the topics you struggled with. Take another practice test, review the manual again, and ask someone with commercial driving experience to explain concepts you find confusing. The second attempt is usually easier because you know what to expect.
Most people pass on the second try if they study the material they missed the first time. Do not get discouraged by a first failure — it is a common step on the way to getting your endorsement.
Frequently Asked Questions
Can I take the F endorsement test without a learner's permit?
No. You must pass the regular written test and hold a valid learner's permit before you can take the F endorsement test. The learner's permit shows that you have already demonstrated knowledge of basic driving rules.
How much time do I have to answer the 20 questions?
Tennessee gives you a set amount of time to complete the test at the Driver Services Center. The exact time limit varies, so ask the staff when you arrive for your test. Practice tests may not have the same time limit, so do not rely on practice test timing as a perfect match.
What happens if I fail the F endorsement test?
You can retake it after a waiting period. Study the topics you missed, use practice tests to identify weak areas, and review the Tennessee Commercial Driver License Manual again. Most people pass on the second or third attempt.
Are the practice test questions the same as the real test questions?
Practice tests are based on the same material and cover the same topics, but the exact wording and scenarios may be different. The real test may include questions you have not seen before, but if you understand the concepts in the manual, you can answer them.
Do I need to study anything else besides the manual and practice tests?
The manual and practice tests cover everything on the test. If you have the chance to observe or ride along with a commercial driver, that real-world experience can help you understand the rules in context, but it is not required to pass the test.
