What is the Georgia CDL knowledge test?

The Georgia CDL knowledge test is a computer-based assessment that tests your knowledge of commercial vehicle regulations and safe driving practices. Before you can take hands-on skills testing, you must first get your Commercial Learner's Permit (CLP) by passing this knowledge test. The test checks your familiarity with Georgia traffic laws, federal regulations, vehicle inspection procedures, and safe driving techniques to ensure you have enough knowledge to operate commercial vehicles safely.

Who needs to take the CDL knowledge test in Georgia?

You'll need to take the Georgia CDL knowledge test in these situations:

  • First-time Commercial Learner's Permit applicants
  • Current CDL holders seeking additional endorsements
  • Drivers upgrading their license class (for example, from Class B to Class A)
  • Individuals with CDLs expired for more than one year requiring reinstatement
  • Drivers transferring an out-of-state CDL who want to add endorsements

Every applicant starts with the general knowledge test which is the foundation of commercial driving knowledge.

Why is the CDL knowledge test important?

The CDL knowledge test is a safety filter, ensuring only qualified individuals operate commercial vehicles in Georgia. Given the size, weight, and potential dangers of commercial vehicles, operators must demonstrate thorough knowledge before getting behind the wheel. The test verifies you understand vehicle handling, safety regulations, emergency procedures, and technical aspects of commercial vehicles to protect all road users.

How does the Georgia test match federal requirements?

Georgia's CDL testing program balances federal requirements with state-specific regulations. The Department of Driver Services (DDS) designs tests that fully comply with Federal Motor Carrier Safety Administration (FMCSA) standards and Georgia's traffic laws. This balanced approach ensures your Georgia CDL will be recognized throughout the United States, allowing you to operate across state lines as long as you meet other interstate commerce requirements.

How many questions are on the Georgia CDL knowledge test?

The Georgia CDL knowledge tests have varying numbers of questions depending on the license type or endorsement:

  • General Knowledge: 50 multiple-choice questions
  • Air Brakes: 25 multiple-choice questions
  • Combination Vehicles: 20 multiple-choice questions
  • Passenger Endorsement: 20 multiple-choice questions
  • School Bus Endorsement: 20 multiple-choice questions
  • Hazardous Materials Endorsement: 30 multiple-choice questions
  • Tank Vehicles Endorsement: 20 multiple-choice questions
  • Doubles/Triples Endorsement: 20 multiple-choice questions

Each question has 4 possible answers, and you must select the best option.

A) It is painted a bright color for visibility

B) It has been properly lubricated

C) It is positioned above the kingpin

D) It has been polished recently

Answer: B) It has been properly lubricated

What score do I need to pass?

In Georgia, you need to score 80% on each separate test:

  • General Knowledge: 40 out of 50 questions
  • Air Brakes: 20 out of 25 questions
  • Combination Vehicles: 16 out of 20 questions
  • Passenger Endorsement: 16 out of 20 questions
  • School Bus Endorsement: 16 out of 20 questions
  • Hazardous Materials Endorsement: 24 out of 30 questions
  • Tank Vehicles Endorsement: 16 out of 20 questions
  • Doubles/Triples Endorsement: 16 out of 20 questions

Each test is scored separately, so you'll only need to retake the tests you don't pass.

What languages can I take the test in?

Georgia only offers CDL knowledge tests in English. This is in line with federal requirements that commercial drivers must be able to read and speak English sufficiently to interpret road signs, communicate with officials, complete required documentation, and understand shipping papers. There are no exceptions to this language requirement for CDL testing in Georgia.

Can I use study aids during the test?

Georgia prohibits the use of any study aids or reference materials during CDL knowledge tests. Using any unauthorized materials will result in immediate test failure. Banned items include:

  • Electronic devices (phones, tablets, calculators)
  • Written notes, cheat sheets, or study guides
  • CDL manuals or handbooks
  • Reference materials including dictionaries
  • Calculators (except when specifically permitted)

Testing centers have secure environments with monitoring to ensure test integrity.

How long do I have to complete the test?

The Georgia Department of Driver Services (DDS) doesn't have time limits for CDL knowledge tests, so you can take your time. Most test-takers complete the general knowledge test in 60-90 minutes and endorsement tests in 30-45 minutes each. If you're taking multiple tests in one session, plan your day accordingly. Applicants with documented learning disabilities or special needs may request reasonable accommodations with proper documentation.

What types of knowledge tests are available?

How similar are practice tests to the actual test?

Our practice tests mirror the Georgia CDL knowledge test format and content areas, but the questions are different. We design our questions to match the style, difficulty, and content coverage of the actual exam. Our practice tests help you:

  • Get used to question formats and phrasing
  • Experience the depth and breadth of content
  • Learn time management for the testing environment
  • Build critical thinking skills for test success

Focus on understanding the underlying principles, not just memorizing answers, as the actual test draws from a large question bank.

Where do I take the CDL knowledge test?

The Georgia CDL knowledge test is administered at Department of Driver Services (DDS) customer service centers that offer commercial licensing. Not all DDS locations offer CDL testing, so verify testing is available before you go. Major testing locations include Atlanta, Savannah, Augusta, Macon, Columbus, and other cities across Georgia. For a complete list of locations offering CDL testing, visit the Georgia DDS website.

Do I need an appointment?

Yes, the Georgia DDS highly recommends scheduling appointments for CDL knowledge tests. You can schedule your testing appointment through:

  • The official DDS website
  • The Georgia DDS mobile app
  • Direct phone contact with your local DDS office

Some locations may accept walk-ins for CDL testing, but this can result in long wait times and possible same-day testing unavailability if daily capacity is met. Scheduling an appointment guarantees your testing time and location.

Can I take the test online?

No, Georgia requires all CDL knowledge tests to be taken in person at authorized DDS locations. This is to ensure proper identification, test security, and testing integrity. This is a federal requirement and applies to all states. The supervised testing environment prevents cheating and confirms the person earning the CDL is the one who took the test.

What do I need to bring to the test?

When you arrive for your Georgia CDL knowledge test, bring:

  • Current valid Georgia driver's license
  • Social Security card or documentation of your Social Security number
  • Citizenship or legal residency proof (birth certificate, U.S. passport, permanent resident card, etc.)
  • Georgia residency documentation (two separate documents showing your Georgia address)
  • Current Medical Examiner's Certificate (DOT medical card, Form MCSA-5876)
  • Completed CDL application form
  • Payment for all applicable fees (cash, check, or credit/debit card)
  • For Hazmat endorsement: Additional identity documentation for security threat assessment

Also bring:

  • Prescription eyeglasses if needed
  • Your appointment confirmation

All documents must be original or certified copies; photocopies are not accepted. If you have document questions, contact the DDS before your appointment.

How early should I arrive?

Plan to arrive 15-20 minutes before your appointment time. This allows for:

  • Document verification processing
  • Application review and completion
  • Fee payment processing
  • Finding the testing area and getting settled

Late arrivals may result in appointment cancellation and rescheduling. First-time CDL applicants should arrive 30 minutes early to allow for additional paperwork processing.

What if I pass?

After you pass your CDL knowledge tests, you will receive a Commercial Learner's Permit (CLP) valid for 365 days (one year) with the following restrictions:

  • 14-day waiting period before taking your skills test
  • A qualified CDL holder must be in the passenger seat during practice driving
  • No passengers (except authorized individuals like instructors)
  • No hazardous materials
  • Additional restrictions based on your vehicle class and endorsements

Your CLP will have notations for any endorsements you tested for.

What can I do with my CLP?

Your Commercial Learner's Permit allows you to practice driving commercial vehicles under supervision before taking the skills test. Use this time to develop and practice the practical skills needed for the three-part skills test (pre-trip inspection, basic controls, and road test). This supervised practice time is crucial to build the confidence and competence needed to pass your skills test.

How long are test scores valid?

Your CDL knowledge test scores are valid for 365 days (one year), just like your CLP. If your CLP expires before you take your skills test, you will need to start over and retake all knowledge tests. There is no extension for score validity, so plan your skills testing within your CLP's one-year window to avoid retesting.

What if I fail?

If you don't pass your CDL knowledge test:

  • You must wait at least until the next business day to retest
  • You only need to retest the sections you didn't pass
  • Use our practice tests to focus on your weak areas
  • Review the topics you got wrong to understand the material better
  • Consider changing your study approach if you're struggling with certain topics

Georgia doesn't have a limit on retesting, but consistent failures mean you need more preparation.

Sample question: If you fail the CDL general knowledge test in Georgia, when can you retest?

A) You must wait 30 days before retesting

B) You can retest at a different location the same day

C) You must wait until at least the next business day

D) You need to retest all test sections, even the ones you passed

Answer: C) You must wait until at least the next business day

How do I schedule the skills test?

After holding your CLP for 14 days:

  • Schedule your skills test online through the Georgia DDS website or by phone at your testing location
  • Verify your CLP is not expired and your medical certificate is current
  • Arrange for a test vehicle that matches your CDL class
  • Pay the $50 skills test fee
  • Choose from available test dates and times

Practice all three parts of the skills test: pre-trip inspection, basic controls, and road test before your test date.
