How Many Questions Are on the Georgia CDL General Knowledge Test?
Fifty multiple-choice questions, 40 correct to pass — that's the Georgia CDL general knowledge test, and it's the same format used almost everywhere in the country, since it's set by federal rule rather than the Georgia DDS.
A federal format layered onto a state-run test
Georgia's own permit test is actually split into two separately-scored sections (Road Rules and Road Signs), but that state-specific structure doesn't carry over here — the CDL general knowledge test is a single 50-question exam under 49 CFR Part 383, identical in length and passing score nationwide.
Topics span vehicle inspection, basic vehicle control, air brakes, cargo securement, and hours-of-service, drawn from the same federal knowledge base every CDL applicant in the country studies.
What Georgia DDS still controls locally
Scheduling, required documents, and Customer Service Center procedures are all set by the Georgia DDS and can vary — the 50-question format is fixed, but how you book and sit the test isn't.
Endorsement-specific tests (air brakes, combination vehicles, and others) are layered on top of the general knowledge test depending on the CDL class and endorsements you're pursuing.
Studying for a federally-set test
Since the topics are the same nationwide, understanding the reasoning behind each rule pays off more than memorizing isolated facts — the same underlying knowledge is tested whether you're in Georgia or anywhere else.
Our free Georgia CDL practice tests spread 100+ original questions across 17 topic areas into multiple shorter sets, giving you more total repetitions than one 50-question run would.
Frequently Asked Questions
Does Georgia's split permit-test format (Road Rules / Road Signs) apply to the CDL test too?
No. That two-section split is specific to Georgia's regular permit test. The CDL general knowledge test is a single federally-set 50-question exam, the same format used nationwide.
Are there other knowledge tests besides the general knowledge test?
Yes, endorsement-specific tests (such as for air brakes, combination vehicles, or hazardous materials) may also be required depending on the type of CDL and endorsements you're pursuing. Confirm current requirements with the Georgia DDS.
What happens if I don't pass the CDL general knowledge test?
Retake policies, including any waiting period or fee, are set by the Georgia DDS and can vary. Check with your local Customer Service Center for current retake rules.
