In the opening pages of the Alabama Commercial Driver Manual, the Chief Examiner from the Alabama Department of Public Safety encourages you to “study diligently” to pass your written exam and become a safe driver. These 20 multiple-choice questions will help you do just that, as they help you review necessary topics, including everything from emergency preparedness to right-of-way rules. Each question also has a hint and explanation, so you’ll be able to answer correctly even if you see the material on the real exam worded slightly differently. Practice often, and read the explanations closely until you feel confident with CDL exam concepts. Good luck at your exam and drive safely on the Alabama roadways, and across the country!

FAQs

How do you get yours?

To obtain a CDL in Alabama, you must first get a commercial learner’s permit (CLP) by passing the required knowledge tests. Hold the CLP for at least 14 days before taking the CDL skills test. Complete any required training and pass the skills test. Ensure you meet all age, medical, and legal requirements.

What is the associated cost?

The cost for a CDL in Alabama includes a $25 application fee for the CLP and a $20-$40 fee for the CDL license, depending on the class and endorsements. Additional fees may apply for skills testing and medical examination.

What are the requirements you need to know about?

CDL requirements in Alabama include being at least 18 years old (21 for interstate driving), holding a valid Alabama driver’s license, passing a medical examination, and successfully completing the knowledge and skills tests. Specific endorsements may require additional tests.

How long does the process take?

The time to get a CDL in Alabama varies depending on individual readiness and training program length. After obtaining a CLP, you must wait at least 14 days before taking the skills test. Training programs can last from a few weeks to several months.

What can get you disqualified from being eligible?

In Alabama, disqualifications from obtaining a CDL include major traffic violations like DUIs or reckless driving, certain criminal convictions, and medical conditions that impair safe driving abilities. Accumulating too many points on your driving record can also lead to disqualification.

Alabama CDL requirements to know

CLP and General Knowledge requirements before skills testing and endorsements

General Knowledge comes first

Start with General Knowledge for your AL CLP. Add Combination Vehicles, Air Brakes, or endorsement tests only when they match the license class and endorsements you need.

CLP is separate from skills testing

Passing the written test does not give you a CDL. After your CLP is issued, federal rules require you to hold it for at least 14 days before the CDL skills test.

Medical certification matters early

Pick the right medical self-certification category early. If you drive non-excepted interstate, keep your DOT medical certification current with the state licensing agency.

ELDT may be required before testing

ELDT may be required before Class A or B skills testing, first-time Passenger or School Bus endorsements, or the HazMat knowledge test. Your training provider submits completion through FMCSA's Training Provider Registry.

Recommended CDL study path

Use General Knowledge as the base, then move into the CDL tests that match your license class and endorsements.

1
Pass General Knowledge first
This is the base CLP knowledge area before endorsement-specific study.
2
Add required CDL areas
Most Class A/B paths also need Air Brakes, Combination Vehicles, or other focused tests.
3
Practice only relevant endorsements
HazMat, Tanker, Passenger, School Bus, and other endorsements matter only when they match your goal.
