Alabama CDL Manual 2026

How to use the Alabama CDL Manual

The ALEA draws its 30-question knowledge test from the Alabama CDL Manual, and you need 80% to pass, which is 24 correct answers. Read the 160 pages once for coverage, then answer practice questions to find the rules that did not stick. Practice tells you what you do not know yet; the CDL Manual is where the rule is actually stated, in the words the state chose.

It is also the only source that settles an argument. When a practice answer and your instinct disagree, the Alabama CDL Manual decides it, and every explanation we write points back into it.
