Arkansas CDL Endorsements
Endorsements are add-ons to your Arkansas CDL that authorize specific vehicle types or cargo. Each requires a separate knowledge test, taken through Arkansas Department of Finance and Administration, and the endorsement codes are federal, so a Arkansas endorsement is recognized in every state. With retail distribution, poultry and food processing, steel and metals shaping Arkansas 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.
