Alabama CDL Classes Explained
Which Alabama CDL class you need depends on vehicle weight, what it tows, and the type of operation, not just the truck size. The three classes are set by federal rule (49 CFR 383.91) and are the same in every state, so a Alabama CDL is valid nationwide. Alabama Law Enforcement Agency issues the license and runs the knowledge and skills tests. Alabama sits along major Southeast freight corridors connecting Gulf ports to Midwest manufacturing centers.
A Class A CDL is generally used for combination vehicles, including tractor-trailers, when the gross combination weight rating is 26,001 pounds or more and the towed unit is over 10,000 pounds.
