Alabama CDL Endorsements
Endorsements are add-ons to your Alabama CDL that authorize specific vehicle types or cargo. Each requires a separate knowledge test, taken through Alabama Law Enforcement Agency, and the endorsement codes are federal, so a Alabama endorsement is recognized in every state. With automotive manufacturing, poultry and food processing, port logistics shaping Alabama freight, the examples under each endorsement show where that endorsement pays off locally.
Not all endorsements apply to every CDL class. Use the CDL Selector to find what you need.
