CDL FAQs
Common questions about the CDL licensing process in Alabama.
What is the difference between a Class A and Class B CDL?
A Class A CDL allows you to operate combination vehicles with a gross combination weight rating (GCWR) of 26,001 lbs or more, where the towed vehicle exceeds 10,000 lbs — such as tractor-trailers. A Class B CDL covers single vehicles over 26,001 lbs or towing a vehicle not exceeding 10,000 lbs, such as straight trucks, buses, and dump trucks.
How do I get a Commercial Learner's Permit (CLP)?
To obtain a CLP in Alabama, you must pass the CDL General Knowledge written test and any endorsement knowledge tests at an ALEA Driver License office. You must hold the CLP for at least 14 days before taking the CDL skills test.
What is a DOT physical and where do I get one?
A DOT physical is a medical examination required for all CDL holders, conducted by a licensed medical examiner listed on the FMCSA National Registry. It evaluates vision, hearing, blood pressure, and overall physical fitness to ensure safe driving.
What endorsements can I add to my CDL?
Common CDL endorsements include: H (Hazardous Materials), N (Tank Vehicles), P (Passenger), S (School Bus), T (Double/Triple Trailers), and X (Combination Tank/HazMat). Each requires passing an additional knowledge test, and some require a skills test.
How long is a CDL valid in Alabama?
In Alabama, a CDL is valid for 4 years. You must renew it before the expiration date and maintain a valid DOT medical certificate throughout the period.
Can I transfer my out-of-state CDL to Alabama?
Yes. If you hold a valid CDL from another state, you can transfer it to Alabama by visiting an ALEA Driver License office, surrendering your out-of-state license, and passing the vision test. Knowledge and skills tests are generally waived for valid out-of-state CDL holders.
