What the Georgia CDL permit test covers
Georgia's Commercial Driver's License (CDL) permit test is a written exam you take before you can operate a commercial vehicle on public roads. The test checks your knowledge of traffic laws, vehicle safety, and the specific rules that explore to commercial trucks and buses. You must pass this test to get your CDL permit, which allows you to practice driving a commercial vehicle with a licensed CDL holder in the seat next to you.
The test is administered by the Georgia Department of Driver Services (DDS) at any of their driver's license offices across the state. You take it on a computer at the office — not online from home. The exam has 50 questions, and you need to answer at least 40 correctly to pass. You have one hour to complete it.
The questions come from Georgia's CDL manual, which covers general knowledge that applies to all commercial drivers, plus knowledge specific to the type of vehicle you plan to drive (straight truck, tractor-trailer, bus, or tanker). If you are testing for multiple vehicle types, you will take a separate test for each one.
Key Takeaways
- Georgia's CDL permit test has 50 questions and you must answer at least 40 correctly to pass, with one hour to complete it.
- You take the test on a computer at a Georgia DDS office, not online, and must bring a valid ID and proof of residency.
- The test covers general CDL knowledge plus vehicle-specific rules depending on which type of commercial vehicle you want to drive.
- Georgia's official CDL manual is the only source material you need; it is free to read from the DDS website or available in print at any DDS office.
- You can retake the test if you fail, but you must wait one day before your next attempt and pay the test fee again.
What documents you need to bring to the test
Before you schedule your test, you must have a valid Georgia driver's license or ID card. If you do not have one, you will need to get one first — the CDL permit test is only for people who already hold a standard driver's license. You also need to bring proof of your current Georgia address, such as a utility bill, lease agreement, or bank statement dated within the last 60 days.
Bring the original documents with you, not copies. The DDS staff will check them before you sit down to test. If your address on your driver's license does not match your current residence, bring both your license and a proof-of-address document so the staff can update your file.
You do not need to bring the CDL manual or any study materials to the test itself. The test is closed-book, meaning you answer questions from memory alone. You are allowed to bring a pen and paper to take notes during the test if you need to work through calculations (for example, weight and balance questions), but you cannot reference any written materials while answering.
How to find and schedule your test appointment
Visit the Georgia DDS website and use their office locator to find the driver's license office nearest you. Not all offices offer CDL testing on every day, so check the schedule for your preferred location. Some offices have limited CDL testing hours, and during busy seasons appointments can fill up weeks in advance.
You can schedule your appointment online through the DDS website, by phone at 678-413-8400, or in person at any DDS office. When you schedule, you will choose the type of CDL test you want to take (general knowledge, passenger vehicle, tanker, hazmat, or other endorsements). The test fee is currently $20, and you pay it when you arrive for your appointment. Bring a debit or credit card, as not all offices accept cash.
If you need to cancel or reschedule, do so at least 24 hours before your appointment. If you miss your appointment without canceling, you forfeit your test fee and must schedule and pay again.
The topics covered on Georgia's CDL general knowledge test
The general knowledge section covers rules and safety practices that explore to all commercial drivers. This includes traffic laws (speed limits, right-of-way, stopping at railroad crossings), vehicle inspection and maintenance (checking brakes, tires, lights, and coupling devices), and safe driving practices (following distance, turning, backing up, and driving in bad weather).
You will also see questions about hours-of-service rules, which limit how long you can drive without a break. Federal law requires commercial drivers to track their driving time, and the test checks whether you understand when you must stop and rest. Questions cover logbook requirements, off-duty time, and penalties for violations.
Other topics include vehicle weight and balance, cargo securement, and what to do if your brakes fail or you lose steering. The test also covers your responsibilities as a commercial driver — for example, you cannot drive under the influence, and you must report certain accidents to law enforcement. If you are testing for a specific vehicle type (tanker, passenger bus, hazmat), you will take an additional test covering rules unique to that vehicle.
Where to find Georgia's official CDL study material
The Georgia DDS publishes the official CDL manual, which is the only source material you need to study. You can read it free as a PDF from the DDS website under their CDL section. The manual is organized by topic and includes all the information tested on the permit exam. Print copies are also available at any Georgia DDS office for a small fee, usually $5 to $10.
The manual is updated periodically to reflect changes in federal and state CDL rules, so make sure you are studying the current version. Check the publication date on the manual before you begin studying. If you downloaded it more than a year ago, visit the DDS website again to confirm you have the latest edition.
Some third-party websites and apps offer CDL practice tests based on Georgia's manual. These can be useful for drilling specific topics and getting a feel for the test format, but they are not official and may contain errors. Use them as a supplement to the official manual, not as a replacement. The official manual is always your most reliable source.
How to study effectively for the test
Start by reading through the entire Georgia CDL manual once to get a sense of the material. Then go back and study one section at a time, taking notes on key points. Focus especially on the topics that are hardest for you — if you struggle with weight calculations or hours-of-service rules, spend extra time on those sections.
After you finish reading a section, close the manual and write down what you remember. This forces your brain to retrieve the information rather than just recognize it on the page. Then check your notes against the manual to see what you missed. Repeat this process for each section.
Use practice tests to identify weak areas and to get comfortable with the test format. Take a full 50-question practice test under timed conditions — sit at a computer, set a timer for one hour, and do not look at the manual. This mimics the real test environment and shows you how much time you have per question (about 72 seconds). After you finish, review every question you missed and find the correct answer in the manual.
What happens if you fail the test
If you do not pass on your first attempt, you can retake it. You must wait at least one day before you schedule your next test, and you pay the $20 test fee again. There is no limit to how many times you can retake the test, so you can keep trying until you pass.
When you fail, ask the DDS staff for a breakdown of which topics gave you the most trouble. Some offices provide a score report that shows your performance by category. Use this information to focus your next study session on the weakest areas. Do not straightforward retake the test without studying more — the questions are randomized, so you will likely see different questions the second time, and you need to know the material, not memorize specific answers.
After you pass the permit test, you will receive your CDL permit. This permit allows you to drive a commercial vehicle only when a licensed CDL holder is sitting next to you in the front seat. You cannot drive alone. The permit is valid for one year, and during that time you must pass the CDL road test (the driving exam) to get your full CDL license.
Frequently Asked Questions
Can I take the CDL permit test online from home?
No. Georgia requires you to take the test in person at a DDS office on a computer provided by the office. You cannot take it online or from home. You must bring a valid ID and proof of current address to the office on the day of your test.
How long is the CDL permit valid after I pass the test?
Your CDL permit is valid for one year from the date you pass the test. During that year, you must pass the CDL road test to get your full license. If your permit expires before you pass the road test, you will need to retake the written permit test and pay the fee again.
Do I need to pass the general knowledge test before I take a vehicle-specific test?
Yes. You must pass the general knowledge test first. After you pass it, you can take additional tests for specific vehicle types (tanker, passenger, hazmat) if you need those endorsements. Each test is separate and has its own fee.
What is the difference between a CDL permit and a CDL license?
A CDL permit allows you to practice driving a commercial vehicle with a licensed CDL holder beside you. A CDL license allows you to drive a commercial vehicle alone. You get the permit by passing the written test; you get the full license by passing the road test (driving exam).
Can I use a practice test from another state to study for Georgia's test?
Practice tests from other states cover similar topics, but Georgia's rules and specific questions may differ. Use Georgia's official manual and Georgia-specific practice tests as your primary study material. You can use out-of-state materials as a general reference, but do not rely on them as your main source.
