CDL licensing in Alabama is administered by the Alabama Law Enforcement Agency. Fees, scheduling, forms, and the official Alabama CDL manual live on the official site: ALEA — official CDL page (verified 2026-08-09).
Truckcess is not affiliated with or endorsed by the Alabama Law Enforcement Agency. Our practice tests cover the federal CDL knowledge standards (49 CFR Part 383) that every state exam is built on; exact question counts, fees, and procedures vary by state and change over time — the official site is always the authority.
How the Alabama CDL process works
- Study the official Alabama CDL manual from the ALEA — state exams draw from it.
- Pass the written knowledge tests to earn your Commercial Learner's Permit (CLP). You can take the CLP knowledge tests before completing ELDT.
- Complete Entry-Level Driver Training (ELDT) from a provider on the federal Training Provider Registry — required before your skills (driving) test. Truckcess provides the theory portion. (Exception: for the HazMat endorsement, ELDT theory is required before its knowledge test.)
- Pass the three-part skills test — vehicle inspection, basic control, and road driving.
The full prep course — every practice test, narrated lessons, the spoken pre-trip trainer — is one-time (Class A $69, Class B $59) with 12 months of access: mytruckcess.com/cdl.
