About the Alabama CDL permit test
The permit test is the General Knowledge test: one written exam, two names. It is the exam every CDL applicant sits, whatever class of license they are working toward. The questions come from the Alabama CDL manual, they are multiple choice, and you need 80% to pass. Alabama Law Enforcement Agency gives the test, and passing it is what earns your commercial learner's permit, the permit you hold before taking the skills test in a truck.
What it covers
Our 10 free questions and the full 81-question General Knowledge bank are drawn from these manual sections:
- Vehicle Inspection
- Basic Control of Your Vehicle
- Shifting Gears
- Seeing
- Communicating
- Controlling Speed
- Managing Space
- Seeing Hazards
Endorsements such as HazMat, Tank, Passenger and School Bus are separate written tests on top of this one. See which Alabama CDL endorsements you need before you book anything, because the endorsement you are missing decides which tests you sit.
What Alabama requires
- The CLP must be held for at least 14 days before the CDL skills test.
- The CLP is valid for 360 days and cannot be renewed; once it expires you retake all knowledge tests and buy a new permit.
- You self-certify your type of driving and, for non-excepted interstate driving, keep a medical examiner's certificate on file; missing medical information removes CDL privileges after a 45-day notice.
- Military service members with recent commercial driving experience can have the skills test waived but still take the knowledge tests.
- Re-examination is required if an Alabama CDL has been expired more than 3 years.

Common questions
Is the Alabama CDL permit test the same as the knowledge test?
Yes. They are the same written exam. It is the General Knowledge test, and passing it is what earns your commercial learner's permit (CLP), so people call it the permit test. A CDL permit practice exam, pretest or mock test all mean practice questions for this same test.
What score do I need to pass the Alabama CDL knowledge test?
You need 80% to pass. Miss more than that and you retake the test, so the goal while studying is to be comfortably above 80%, not just at it.
Where do I take the Alabama CDL knowledge test?
At Alabama Law Enforcement Agency. Passing the General Knowledge test is what earns your commercial learner's permit, which you hold before the skills test.
Is this free test the real Alabama CDL exam?
No. These are 10 real questions from the same General Knowledge bank our paid study material uses, so the style and difficulty match what you are studying for. The official exam is given only by Alabama Law Enforcement Agency.
